ABSTRACT D:\My Journal\papers\Vol 4 ISSUE 1\1 senem sadri Turkey\check for updates2020ijcua.tif
The interaction between transport, land-uses and travel patterns produce diverse transportation problems in urban cities with traffic congestion as the most visible manifestation. Traffic congestion is a frequent phenomenon in most cities around the globe. This paper reviews the interaction between land-use traffic congestion through published literature. The objective of this study is to encourage and provide researchers with future research directions in land-use and traffic congestion. For this purpose, a systematic review was performed analysing 45 articles from the year 2010 to 2020 using a descriptive approach. Subsequently, the results of the study show that although the interaction between land-use and traffic congestion has gained currency in developed countries far less is known on this subject in developing parts of the world, though new evidence is steadily accumulating. Consequently, limitations of this work are presented, opportunities are identified for future lines of research. Finally, the conclusion confirms the need for further research addressing the methodological concerns.

Conceptualizing Sustainable Transportation for City of Pune, IndiaIJERA Editor
Pune the second largest city of Maharashtra state of Indian union is witnessing large scale urban sprawl and its
negative ramifications in last couple of decades. Urban sprawl is defined as dispersed and discontinuous
suburban land development associated with low population densities and high auto dependence. This
phenomenon is adversely affecting sustainability of the city because of its negative environmental, social and
economic impacts. It saps local resources, destroys open space and farmland, and increases the energy
consumption of mobility by promoting long travel distances. Another problem is high levels of traffic
congestion and harmful emissions causing environmental pollution. There is a plethora of research that sought
to address the issue of urban sustainability and combat sprawl; little has been done on developing analytical
tools that could be used to assess the future of urban sustainability for Indian cities and for Pune in particular.
This paper explores that how particular land use development patterns or the expansion of the current urban
transportation infrastructure are likely to impact urban sustainability.

ABSTRACT
Many studies have been conducted over the last 20 years to determine and measure factors that affect the walkability of city streets. Walkability is an essential factor in deciding whether a city is green or sustainable. This paper creates a comprehensive walkability index by analysing built environmental indicators that affect walkability. This research was conducted on mixed land use streets in Cairo, Egypt, combining the results from an online survey and a walkability assessment model developed by multi-criteria decision analysis techniques. The results were based on a three-pillar approach starting with the theoretical background to frame the walkability indicator, numerical assessment over the Egyptian cases using a multi-criteria decision-making (MCDM) technique and a qualitative user perception survey. Our results confirm that determining to what extent Cairo’s streets are walkable is crucial to enhancing pedestrians’ perceptions of the walking environment. Furthermore, the results illustrated the essential factors within the built environment indicators that influence pedestrian walking behaviour.

ABSTRACT D:\My Journal\papers\Vol 4 ISSUE 1\1 senem sadri Turkey\check for updates2020ijcua.tif
Transportation has always been the backbone of development. Transit-oriented development (TOD) has been theorized, piloted and expanded increasingly in the past few decades. In this regard, this paper investigates the relationship between urban development, the transportation process, and the required implementation guidelines within fast-urbanizing cities, such as Cairo. After reviewing different related sustainable development theories, the study investigates pioneering case studies that have applied TOD and provided adequate implementation frameworks. The authors then extract and compare a set of required policies. The current Egyptian development paradigm is then discussed in relation to these enabling policies, focusing on Greater Cairo Region, Egypt. The authors debate previous development plans, progress, and newly proposed ones, focusing on the transportation process as the means for development. The study concludes with a set of required guidelines to ensure the integration of transportation with land-use planning, thus ensuring a more prosperous and inclusive urban development.

Perception of Urban Dwellers on Street Interlocking in Maiduguri, Borno State...Premier Publishers
The document discusses a study that assessed the perceptions of urban dwellers in Maiduguri, Nigeria regarding street interlocking construction in their area. 200 questionnaires were administered across 4 wards. The respondents perceived street interlocking positively due to benefits like beautification and improved walkways. No negative environmental impacts of street interlocking were found. The study aimed to understand perceptions in order to support sustainable urban landscape management.
This document summarizes a meta-analysis of over 200 studies on the relationship between the built environment and travel behavior. The analysis found that while travel variables are generally insensitive to changes in the built environment, certain environmental factors can significantly influence travel. Vehicle miles traveled is most strongly related to accessibility and street network design, while walking is most strongly linked to land use diversity, intersection density, and nearby destinations. Bus and train use correlate most with proximity to transit and street networks. Population and job density have weaker associations once other variables are controlled for. However, the results should be interpreted cautiously due to small sample sizes and limited controls for residential preferences in the studies.

This document summarizes a meta-analysis of over 200 studies examining the relationship between the built environment and travel behavior. The study aims to quantify the effects of variables like density, land use diversity, and design on travel outcomes including vehicle miles traveled, walking, and transit use. It finds that travel is generally inelastic to changes in the built environment, with elasticities below 0.39 for most relationships. Vehicle miles traveled is most strongly associated with accessibility and street design, while walking correlates most with land use diversity, intersections and nearby destinations. The study concludes that its elasticities can help adjust travel models to account for built environment impacts, but more research is still needed to address self-selection biases.

(Geo-) Daten für ein besseres Verständnis der FahrradmobilitätMartin L
This document summarizes key points from a presentation about using data to better understand bicycle mobility.
The presentation discusses how (1) historically, transportation planning focused on motorized modes and marginalized walking and cycling due to a lack of data, (2) new technologies now enable widespread collection of mobility data at fine-grained spatial and temporal scales, and (3) combining these diverse data sources could provide insights but also challenges relating to data integration and ensuring data quality and representation. The presentation calls for more work developing methods and models to fuse different data types and involve stakeholders to create an evidence base that increases visibility and support for sustainable transport.
This document reviews research on planning Transit Oriented Development (TOD) through the integration of land use and transportation. It discusses methods, criteria and indicators used in TOD research over the last 5 years. It also reviews strategic plans and public transportation plans implementing TOD in cities worldwide. Finally, it provides a cross-continent comparison of TOD implementation and the integration of transportation and land use planning. The document concludes that practicing TOD through integrated land use and transportation planning is an alternative solution for achieving master plan objectives and addressing urban issues like congestion, travel time reduction, and car dependency.

Synthesis Paper - Sarah Hooker & Ping Na Huang - Vancouver TransportationSarah Mae Hooker
This document summarizes a study that examines how modes of transportation decision-making vary across distance, commute time, and accessibility to downtown Vancouver. The study analyzes census and transportation data from Vancouver's 22 local planning areas. It investigates the relationship between residents' choice of transportation to work and their commute times using alternative modes like public transit and biking. The study also examines how accessibility to public transit and bikeways affects transportation decisions.
This document provides an overview of transit-oriented development (TOD), including its definition, types, goals, planning considerations, case studies, and how its effects are measured. TOD aims to maximize access to public transport through compact, mixed-use development near transit facilities. Case studies discussed include developments in the US, Brazil, and Australia that incorporated TOD principles like density, mixed uses, walkability and public transport access to achieve goals like increased ridership and reduced automobile dependence. A variety of indicators are used to measure TOD outcomes, such as ridership, vehicle ownership, and accessibility.

A Case Study Of Sustainable Urban Planning Principles In Curitiba (Brazil) An...Nathan Mathis
This document presents a case study comparing principles of sustainable urban planning in Curitiba, Brazil and their applicability in Shiraz, Iran. It analyzes how Curitiba has implemented sustainability strategies since the 1960s through integrated approaches combining decision making, education, transportation, public welfare, heritage conservation, and waste management. While every urban context has unique opportunities and constraints, the study argues many lessons can be learned from Curitiba's success that could apply to improving sustainability in Shiraz if adapted appropriately to its local conditions.
This document summarizes a research paper that studied factors influencing cycling using data from the 2000 Bay Area Travel Survey. The study found that street block size and bike lane density encouraged cycling, while population density deterred it. Previous literature found mixed results on factors like age, sex, and infrastructure, possibly due to varying contexts. This study aims to build more accurate cycling prediction models by excluding non-bike owning households. It analyzes urban form, demographic, and travel data for over 28,000 people to model cycling rates.
In spite of the many advancementsinsafety technology, roadway design and engineering as well as
several policy initiativesaimed at addressingtraffic crashes (and it concomitant injuries and fatalities); it
continuesto saddle humanity and present significant health hazards and threats to the socio-economic wellbeing
of the inhabitants of this earth. Even though federal and state transportation engineers, policy makers, planners
and researchers have spent large sums of money and effort on this complex and ubiquitous problem, traffic
crashes is one of the top causes of fatal and non-fatal injuries in the United States. In this work a piecewise
approach was used to perform an exploratory,systemic characterization and analysis of the six-year (2008-
2013) traffic crash data from North Dakota to discover the nature, peculiarities and trends in the data.Several
important features and trends in the data were discovered and the outcome of this paper can be further used for
engineering design, planning and policy analysis. The research approach could be duplicated in any other state
to enhance its societal benefits. Heterogeneity and uncertainty will be fully addressed in future work.

Urban design is a technique and knowledge seeking to organize and improve urban qualities
and increase the quality of citizenship life. Based on the perspectives and objectives of urban design, the
dominant intention in all urbanism activities is to reach high humanistic and social dimensions. In fact,
what give meaning to a city are the social aspects raised in recent urban activities, in addition to the
physical and visual body of it. Over the past decade the quality of the walking environment has become
a significant factor in transportation planning and design in developed countries. It is argued that the
pedestrians’ environment has been ignored in favors of automobile. The purpose of this study was to
examine the effects of walkability on property values and investment returns. Research method is
descriptive. The method of collected data is field. Also, were used questionnaire tools in order to
collecting data. On the other hand, was referred to municipality 9 region due to, studied area was
located in this urban region.
In continue, was used SWOT technique in order to analyzing questionnaire. At finally, proposed
strategies in order to improving urban space qualify.
Stakeholder analysis is component in a project design and implementation central to achievement of the goals and objectives for which projects are carried out. This study aimed at establishing the effect of stakeholder analysis on performance of road construction projects in Elgeyo Marakwet County. The study was anchored on Stakeholder Theory. The study population comprised of 19338 individuals who included employees of the county working within the road sector, personnel within various road construction agencies, contractors and community beneficiaries of the project. Stratified random sampling was then used to group individuals into two homogenous groups, one working directly with the project and the other of beneficiaries. Proportionate random sampling technique was then employed to sample 103 respondents in the first group who included Managers (4), County government employees (29), KURA (6), KenHA (6), KERRA (13) and Contractors (45). Simple random sampling was adopted to select 377 respondents from the community. Data collection instruments were self-administered questionnaires for personnel working directly with the project. On the other hand research assistants facilitated focused group discussions to get views from the community stakeholders. Both descriptive and inferential statistics informed the data analysis and presentation. Descriptive statistics included; percentages, means, standard and deviation. Inferential statistics was Analysis of Variance (ANOVA) and multiple ordinal regression equation analysis. Statistical package for Social Sciences (SPSS 23.0) software helped in data analysis. The study found out that stakeholder analysis had significant effect on performance of road construction projects (β3=0.203, P <0.05) on performance of road construction projects in Elgeyo Marakwet. The study recommends county Government should develop blueprints to guide road contractors in road project activities. Hence establish a favourable environment for implementations of road projects.
The document discusses the connections between transportation and land use. It explores how transportation influences development patterns and travel choices, and vice versa. It also looks at the relationships between density, sustainability, and transportation modes in cities around the world. Specifically, it examines the links between density, emissions, and commuting by private vehicles versus public transit or active transportation in Canadian cities.
The Impact of Waiting Time on Pedestrian Violations at Signalized Intersectionscivejjour
The phenomenon that pedestrian violates traffic signals at intersections and crosses with danger is
universal. This study aims to find out the influence of the waiting time of pedestrians at an intersection and
the three main factors of pedestrian violations. In this study, 13 intersections and 1075 violations sample
were collected in Suzhou China, which had different maximum waiting times. The validation would use the
complementary video data. There are several factors, which have great influence on the proportion of
pedestrian violations, such as the age, sex, arrive time, red phase, conflicting traffic volume and the length
of volume crosswalks. Additionally, The significance of pedestrian maximum waiting time was highlighted
in the end. For the purpose of reducing dangerous pedestrian behaviors at signalized intersections,
minimizing waiting times is supposed to be one proper way.
THE IMPACT OF WAITING TIME ON PEDESTRIAN VIOLATIONS AT SIGNALIZED INTERSECTIONS civej
This document summarizes a study that examined the impact of waiting time on pedestrian violations at signalized intersections in China. The study observed 13 intersections and recorded data on over 1,000 pedestrian crossings. It found that longer waiting times for pedestrians correlated with higher rates of violations. Specifically, factors like age, gender, arrival time, traffic volume, and length of the crossing period all influenced violation rates. The study concluded that minimizing pedestrian waiting times could help reduce dangerous crossing behaviors at intersections.
This document describes a multi-agent model used to develop and assess urban forms in terms of sustainability, focusing on transportation, land use distribution, and vehicle emission pollution minimization. Two city forms are examined - a compact city and a multi-nuclear city. The model generates land use maps for each city form based on transportation networks and user preferences. An activity-based transportation model then simulates travel patterns and evaluates total travel, trips, and accessibility to determine pollution emissions. Planners can provide input to adjust the computer-generated maps. The goal is to understand the planner's options for developing sustainable cities and determine the optimal city form.
Large cities in developing countries are characterized by growth in automobile ownership, insufficient
transportation infrastructure and service development. These cities often suffer from congestion, poor mobility
and accessibility, significant economic waste, adverse environmental impact and safety problems. This paper
focuses on identification of travel time characteristics and other traffic parameters and to develop a predictive
model for travel time on Akure major roads. Data on travel time were collected for vehicles during the morning
and evening peak periods using floating car technique. The data was analyzed using Statistical Packages for
Social Sciences (SPSS) and fitted into Multiple Regression model to establish a relationship between the
Travel Time and other road traffic parameters. Travel time (Tt) was modeled as a function of section length
(X1), number of intersections (X2), pedestrian/ economic activities (X3), Traffic volume (X4), enforcement
agency (X5) and road width (X6). The Coefficient of multiple determination R2 was 0.702 which means that
there is 70.2% of the dependent variable (travel time) in the forward direction as explained (accounted) by the
independent variables and 72.2% in the opposite direction. The result revealed that section length, pedestrian
economic activity and traffic volume were all significant at 5% level and has a positive relationship with travel
time in both forward and reverse direction. The model identifies the impact of these traffic parameters on travel
time and recommend measures for improvement.

ABSTRACT D:\My Journal\papers\Vol 4 ISSUE 1\1 senem sadri Turkey\check for updates2020ijcua.tif
This study investigates how urban parks can contribute to helping cities become more sustainable through developing a set of criteria for the sustainable design of urban parks. Today, there is no example around the world where all the proposed sustainable design criteria are applied together in a specific urban park. In this context, this study aims to make a novel contribution by systematically reviewing the literature on the sustainable design of urban parks. In the light of research findings, this study contributes to the implementation of a comprehensive sustainable park design practice in our cities in the future. These design criteria may further serve as performance indicators to offer information and know-how to local authorities, practitioners, communities, and other actors in this field to help them assess their success levels and progress over time.

ABSTRACT D:\My Journal\papers\Vol 4 ISSUE 1\1 senem sadri Turkey\check for updates2020ijcua.tif
Rehabilitation projects are interventions that can lead to the transformation of the socio-spatial structure of obsolescent neighborhoods. The main intention of such projects is the creation and/or improvement of social interactions after physical and functional interventions. Urban Renewal Organization of Tehran (UROT) is tasked with identification of target obsolescent neighborhoods, preparation of neighborhood development plans and implementation of rehabilitation projects to improve the quality of space and stimulate social interactions. In this paper, three urban spaces in different scales (“micro” for neighborhoods, “meso” for local and “macro” for trans-local scales), designed and implemented by UROT, were selected as a case study. By designing and filling a questionnaire and after analyzing research findings, the effect of the scale of the urban project on different activities was evaluated based on the Gehl model. Overall, in the expanded model based on the scale of space, an inverse ratio between the scale of space and both optional selective and social activities has been revealed.

(Geo-) Daten für ein besseres Verständnis der FahrradmobilitätMartin L
This document summarizes key points from a presentation about using data to better understand bicycle mobility.
The presentation discusses how (1) historically, transportation planning focused on motorized modes and marginalized walking and cycling due to a lack of data, (2) new technologies now enable widespread collection of mobility data at fine-grained spatial and temporal scales, and (3) combining these diverse data sources could provide insights but also challenges relating to data integration and ensuring data quality and representation. The presentation calls for more work developing methods and models to fuse different data types and involve stakeholders to create an evidence base that increases visibility and support for sustainable transport.

This document presents a case study comparing principles of sustainable urban planning in Curitiba, Brazil and their applicability in Shiraz, Iran. It analyzes how Curitiba has implemented sustainability strategies since the 1960s through integrated approaches combining decision making, education, transportation, public welfare, heritage conservation, and waste management. While every urban context has unique opportunities and constraints, the study argues many lessons can be learned from Curitiba's success that could apply to improving sustainability in Shiraz if adapted appropriately to its local conditions.
This document summarizes a research paper that studied factors influencing cycling using data from the 2000 Bay Area Travel Survey. The study found that street block size and bike lane density encouraged cycling, while population density deterred it. Previous literature found mixed results on factors like age, sex, and infrastructure, possibly due to varying contexts. This study aims to build more accurate cycling prediction models by excluding non-bike owning households. It analyzes urban form, demographic, and travel data for over 28,000 people to model cycling rates.
In spite of the many advancementsinsafety technology, roadway design and engineering as well as
several policy initiativesaimed at addressingtraffic crashes (and it concomitant injuries and fatalities); it
continuesto saddle humanity and present significant health hazards and threats to the socio-economic wellbeing
of the inhabitants of this earth. Even though federal and state transportation engineers, policy makers, planners
and researchers have spent large sums of money and effort on this complex and ubiquitous problem, traffic
crashes is one of the top causes of fatal and non-fatal injuries in the United States. In this work a piecewise
approach was used to perform an exploratory,systemic characterization and analysis of the six-year (2008-
2013) traffic crash data from North Dakota to discover the nature, peculiarities and trends in the data.Several
important features and trends in the data were discovered and the outcome of this paper can be further used for

Urban design is a technique and knowledge seeking to organize and improve urban qualities
and increase the quality of citizenship life. Based on the perspectives and objectives of urban design, the
dominant intention in all urbanism activities is to reach high humanistic and social dimensions. In fact,
what give meaning to a city are the social aspects raised in recent urban activities, in addition to the
physical and visual body of it. Over the past decade the quality of the walking environment has become
a significant factor in transportation planning and design in developed countries. It is argued that the
pedestrians’ environment has been ignored in favors of automobile. The purpose of this study was to
examine the effects of walkability on property values and investment returns. Research method is
descriptive. The method of collected data is field. Also, were used questionnaire tools in order to
collecting data. On the other hand, was referred to municipality 9 region due to, studied area was
located in this urban region.
In continue, was used SWOT technique in order to analyzing questionnaire. At finally, proposed

Stakeholder analysis is component in a project design and implementation central to achievement of the goals and objectives for which projects are carried out. This study aimed at establishing the effect of stakeholder analysis on performance of road construction projects in Elgeyo Marakwet County. The study was anchored on Stakeholder Theory. The study population comprised of 19338 individuals who included employees of the county working within the road sector, personnel within various road construction agencies, contractors and community beneficiaries of the project. Stratified random sampling was then used to group individuals into two homogenous groups, one working directly with the project and the other of beneficiaries. Proportionate random sampling technique was then employed to sample 103 respondents in the first group who included Managers (4), County government employees (29), KURA (6), KenHA (6), KERRA (13) and Contractors (45). Simple random sampling was adopted to select 377 respondents from the community. Data collection instruments were self-administered questionnaires for personnel working directly with the project. On the other hand research assistants facilitated focused group discussions to get views from the community stakeholders. Both descriptive and inferential statistics informed the data analysis and presentation. Descriptive statistics included; percentages, means, standard and deviation. Inferential statistics was Analysis of Variance (ANOVA) and multiple ordinal regression equation analysis. Statistical package for Social Sciences (SPSS 23.0) software helped in data analysis. The study found out that stakeholder analysis had significant effect on performance of road construction projects (β3=0.203, P <0.05) on performance of road construction projects in Elgeyo Marakwet. The study recommends county Government should develop blueprints to guide road contractors in road project activities. Hence establish a favourable environment for implementations of road projects.

The Impact of Waiting Time on Pedestrian Violations at Signalized Intersectionscivejjour
The phenomenon that pedestrian violates traffic signals at intersections and crosses with danger is
universal. This study aims to find out the influence of the waiting time of pedestrians at an intersection and
the three main factors of pedestrian violations. In this study, 13 intersections and 1075 violations sample
were collected in Suzhou China, which had different maximum waiting times. The validation would use the
complementary video data. There are several factors, which have great influence on the proportion of
pedestrian violations, such as the age, sex, arrive time, red phase, conflicting traffic volume and the length
of volume crosswalks. Additionally, The significance of pedestrian maximum waiting time was highlighted
in the end. For the purpose of reducing dangerous pedestrian behaviors at signalized intersections,
minimizing waiting times is supposed to be one proper way.
THE IMPACT OF WAITING TIME ON PEDESTRIAN VIOLATIONS AT SIGNALIZED INTERSECTIONS civej
This document summarizes a study that examined the impact of waiting time on pedestrian violations at signalized intersections in China. The study observed 13 intersections and recorded data on over 1,000 pedestrian crossings. It found that longer waiting times for pedestrians correlated with higher rates of violations. Specifically, factors like age, gender, arrival time, traffic volume, and length of the crossing period all influenced violation rates. The study concluded that minimizing pedestrian waiting times could help reduce dangerous crossing behaviors at intersections.
This document describes a multi-agent model used to develop and assess urban forms in terms of sustainability, focusing on transportation, land use distribution, and vehicle emission pollution minimization. Two city forms are examined - a compact city and a multi-nuclear city. The model generates land use maps for each city form based on transportation networks and user preferences. An activity-based transportation model then simulates travel patterns and evaluates total travel, trips, and accessibility to determine pollution emissions. Planners can provide input to adjust the computer-generated maps. The goal is to understand the planner's options for developing sustainable cities and determine the optimal city form.
Large cities in developing countries are characterized by growth in automobile ownership, insufficient
transportation infrastructure and service development. These cities often suffer from congestion, poor mobility
and accessibility, significant economic waste, adverse environmental impact and safety problems. This paper
focuses on identification of travel time characteristics and other traffic parameters and to develop a predictive
model for travel time on Akure major roads. Data on travel time were collected for vehicles during the morning
and evening peak periods using floating car technique. The data was analyzed using Statistical Packages for
Social Sciences (SPSS) and fitted into Multiple Regression model to establish a relationship between the
Travel Time and other road traffic parameters. Travel time (Tt) was modeled as a function of section length
(X1), number of intersections (X2), pedestrian/ economic activities (X3), Traffic volume (X4), enforcement
agency (X5) and road width (X6). The Coefficient of multiple determination R2 was 0.702 which means that
there is 70.2% of the dependent variable (travel time) in the forward direction as explained (accounted) by the
independent variables and 72.2% in the opposite direction. The result revealed that section length, pedestrian
economic activity and traffic volume were all significant at 5% level and has a positive relationship with travel
time in both forward and reverse direction. The model identifies the impact of these traffic parameters on travel
time and recommend measures for improvement.

This study investigates how urban parks can contribute to helping cities become more sustainable through developing a set of criteria for the sustainable design of urban parks. Today, there is no example around the world where all the proposed sustainable design criteria are applied together in a specific urban park. In this context, this study aims to make a novel contribution by systematically reviewing the literature on the sustainable design of urban parks. In the light of research findings, this study contributes to the implementation of a comprehensive sustainable park design practice in our cities in the future. These design criteria may further serve as performance indicators to offer information and know-how to local authorities, practitioners, communities, and other actors in this field to help them assess their success levels and progress over time.

ABSTRACT D:\My Journal\papers\Vol 4 ISSUE 1\1 senem sadri Turkey\check for updates2020ijcua.tif
The COVID-19 lockdown period has highlighted the ability of housing to accommodate a comprehensive programme typical of the city and its public space. Housing units of under 60 m2 and in blocks of flats are the more vulnerable, as they have a higher percentage of non-community open spaces. That problem was analysed using a methodology based on psychological, urban planning and architectural indicators applied to two coastal cities in the Mediterranean area of southern Spain. The results highlight three aspects in this type of dwelling: the need to consider the orientation of the housing to improve the quality of indoor and outdoor space; the need in public housing policies for a greater number of rooms to facilitate remote working; and finally, the importance of functional terraces overlooking green areas.

Recently the effect of greenhouse gases (GHGs) is worldwide terrified anxiety to the public and scholars. Even this global problem is one of the great issues that continuously makes worrying the governments and environmentalists, but its solution findings are not out of the image at all. In this study, we have proposed and analysed a mathematical model for the solvable management of GHGs by sowing the seeds of green building dynamic systems. Moreover, in the model, the human community is used to enhance the production power of individuals of green buildings by absorbing the GHGs. The model is analysed by stability analysis at the equilibrium points: trivial and global equilibrium, and also by convincing the stability and instability of the system of equations. The behaviour of the propound model has been developed by numerical simulations which shows the rate of the fruitfulness of GHG components.

ABSTRACT D:\My Journal\papers\Vol 4 ISSUE 1\1 senem sadri Turkey\check for updates2020ijcua.tif
Afghanistan has suffered from four decades of war, causing a massive migration of the rural population to the cities. Kabul was originally designed for 1,5 million people, whereas there are now 5 million in the city. The importation of modern western styles housing for rapid reconstruction reveals apparent cultural conflict and a significant environmental footprint. The new drive for sustainable reconstruction should consider the use of local materials combined with modern technologies. Earthen architecture underlies the embodiment of Afghan architecture. This research aims to revisit traditional Afghan earthen construction with the tools of industrial modernity. The three soils of the Kabul region are first characterized. Sun-dried mud brick and compressive earth block, with and without stabilization have been prepared and tested in the laboratory to develop the most suitable earth construction element which is cost-effective and easily available compared to imported modern products.

Tourism is a major economic source for Egypt, due to its significant natural and cultural attractions. Yet, rapid development and construction of touristic facilities have a negative impact on the fragile natural and cultural heritage. This paper studies the recent touristic developments of the coastal stretch of Ain-Sukhna on the Red Sea coastal region of Galala Mountain, and their impact on the surrounding natural and cultural attractions. Coral reefs and rich marine life have made this stretch among the prime fishing and scuba diving destinations in the world. The area is also famous for its year-round sunny beaches and the spectacular coastal scenic drive where Galala Mountain reaches the Red Sea. Recently, development has started on the mountains following the construction of Galala Mountain Road. Galala City started with Galala University and several residential, touristic, and commercial facilities. This paper studies the pattern of development in the area during the past 40 years and assesses its impact on natural and cultural resources.

ABSTRACT
Heritage admits diverse readings depending on different territorial spaces, contexts, and knowledge fields. The relation between Heritage and the social contexts is one of these knowledge areas. But Heritage accepts a dual perception as a cultural reflection. It may be considered either as the origins of the conflicts or the engine for recomposing disrupted territories. The paper proposes a reflection on the topics related to conflict territories and the roles currently played by Cultural Heritage. The recomposition of conflict territories is based on a continuous intercultural approach with important contributions from human rights, genders equality, intercultural dialogue perspectives and the fact of taking heritage as a territorial stabilization factor. The paper presents specific practical cases in the Eastern Mediterranean region where actions on Heritage religious elements collide with the national sovereign of the respective current countries. A comparative study among these different actions proves that the initial clashes can be progressively transformed into strategies able to become the future guideline for the resolution of heritage regional conflicts. These conflicts reflect two discourses: political (with strong links between national identity and religion) and scientific (with a clash between static concept and dynamic vision) where objects interact with the visitors.

ABSTRACT
Since the 1960s, new town developments within large metropolises have been widely adopted to decongest the city centres, especially in Asian cities. This paper provides a brief account of the liveability dimensions of two new townships developed in large metropolitan areas: Senri New Town in Osaka and Purbachal New Town in Dhaka. The study primarily draws on master plans of the two developments to identify how the components of the plans reflect the physical, social, functional and safety dimensions of a proposed liveability framework. The methodology combines a review of masters plans with scholarly and grey literature on the two new town developments. The findings show while the social and functional dimensions are integrated with Senri New Town; Purbachal New Town, though more recent, appears to have missed opportunities for diversifying density, social mix and mass transit. The paper concludes that the comparative case, Senri-New Town provides insights on how public-private people participation can leverage citizen-centred design for more liveable residential living environments in developing cities.

ABSTRACT
Nowadays, uncontrolled urbanisation is one of the major problems facing Algerian oasis regions. The monitoring and evaluation of its landscape transformations remain a key step for any oasis sustainability project. This study highlights the evolution of spatial growth in the city of Adrar in southern Algeria during the period 1986-2016 by establishing a Spatio-temporal mapping and landscape quantification. The methodological approach is based on a multi-temporal analysis of Landsat satellite images for 1986, 1996, 2006 and 2016, and the application of landscape metrics. The results show two opposite spatial trends: significant growth of built-up areas against an excessive loss of palm groves. The landscape metrics allowed the identification of a progressive fragmentation process characterising the palm groves. Thus, the findings of this study show the utility of satellite imagery and landscape metrics approach for monitoring urbanisation patterns and assessing their impacts on oasis ecosystems.

Participation in decision-making processes foreshadows enabling citizens, communities, non-governmental organizations and other interested parties to influence the formulation of policies and laws affecting them. The purpose of this study is not only to review Lithuanian legal documents but also to analyse recent processes in Kaunas city planning. Kaunas city is undergoing various urban processes, which do not always meet the needs of the community. This study presents an analysis of the forms of community involvement in the urban planning processes and survey data on the effectiveness of community involvement. The methodology requires using a sociological survey with representatives of the city community and a comparative analysis between legal obligations and actual urbanization process.

ABSTRACT D:\My Journal\papers\Vol 4 ISSUE 1\1 senem sadri Turkey\check for updates2020ijcua.tif
Assessing the impact of urban morphology on the indoor thermal condition of housing in a tourism city in central Vietnam — Hoi An City is the main objective of this study. The research process is carried out by a variety of methods including in situ surveys, measuring with temperature sensors, data analysis and map analysis. Four houses, located in two areas with different urban forms, were selected for measurement within one month to investigate the differences in housing indoor temperature. The impact of urban morphology on housing was thereafter determined. Temperature sensors were permanently installed in 4 houses; based on these empirical measurements and data collected, the paper addresses solutions to improve urban morphology and indoor thermal condition.

ABSTRACT D:\My Journal\papers\Vol 4 ISSUE 1\1 senem sadri Turkey\check for updates2020ijcua.tif
The phenomenon of planning involving citizen’s participation in planning literature has been from the second half of the 20th century. Indeed, different methods and techniques have been used in the process. However, participatory practices are time-consuming and negotiations are tiresome. Accordingly, the integration of developing digital technologies into participatory processes has been seen as a potential to reach large audiences and provide time-space independence. Within the scope of this research, a detailed literature review was done regarding e-participation, and ten (10) examples representing the upper levels at the ladder of participation were examined within the context of the project, participation, and socio-technical criteria. SWOT analyzes were structured by grouping similar applications, and current trends for the use of e-participation in urban design have been revealed. The analysis showed that citizens e participation- participation tend to allow citizen design or location-based interaction, playful interfaces and game elements which can be sources for encouragement.

ABSTRACT D:\My Journal\papers\Vol 4 ISSUE 1\1 senem sadri Turkey\check for updates2020ijcua.tif
For decades, numerous countries have been witnessing the Street Children phenomenon where millions of children worldwide are subjected to risks. Despite the crucial role of intermediate non-residential interventions - using drop-in centers- in protecting and rehabilitating street children, there is a paucity of research addressing the quality of design of these centers and how architecture might influence their operational process. Those observations invite investigating drop-in centers used in practice from a design perspective and question adapting architectural applications for humanitarian emergencies, focusing on “Child-Friendly Spaces”. The study aims to provide solutions for better quality design, facilitating operational challenges. The methodology undertakes the investigation through primary and secondary axes. This involves conducting literature and international precedents review and secondarily, an Egyptian contextual first-hand documentation and qualitative analysis of selected centers.

ABSTRACT
The notion of “Cultural heritage” is quite modern compared to other humanistic fields developed in the last century. Conservation as a science has emerged and took shape during international conventions and treaties in many places in Europe and developed various frameworks to recognize the heritage and its value but based on “Eurocentric bias” criteria. The fact of sharing universal values and common practices during the age of globalization had a significant impact on conservation actions in contexts utterly different from western societies and don’t share the same historical or cultural dimensions. Therefore, this study traces the history of the evolution of conservation in the west from two perspectives; the historical one and the developing methodologies, and the philosophies behind the main theories in conservation. Cultural heritage is a reflection of the identity of the society and its past; thus, this study outlines the development of conservation practices in Egypt within the international approaches in a chronological order to investigate the social response and the impact of the political and cultural influence of the cultural consciousness of the society and the conservation actions in the Egyptian context. Furthermore, to investigate the contribution of international charters in developing national policies in Egypt.

ABSTRACT
The present study argues that the urban form of affordable housing projects affects safety and security. The study examines the level of safety and security in the Prince Fawaz project proposing recommendations that enhance it. Theories and approaches concerned with the environmental crime are initially reviewed. Then, urban and architectural features as well as crime rates and patterns are documented. Also, trace and behaviour observations are carried out. The observations monitored urban features and behaviours associated with crime or fear of crime. Residents’ perception for security and fear of crime is extracted through a questionnaire. A Space Syntax is processed and linked with the questionnaire and observation outputs. Observations demonstrate a semblance of fear of crime which is supported by records of car and home theft. Although the questionnaire reflects a suitable level of security, it points to peripheral spaces and areas around mosques and shops as the less secure. However, enhancing security in the Prince Fawaz project requires urban interventions including controlling access to peripheral spaces, reviving areas detected to be unsafe, repositioning elements causing visual obstacles and enhancing appearance by vegetation and sustainable maintenance. Besides, reformulating the movement network so that an appropriate integration between residents and strangers is achieved. On the conceptual level, the study proves that none of the theories of environmental crime can act as a comprehensive approach; but each can partly work.

ABSTRACT D:\My Journal\papers\Vol 4 ISSUE 1\1 senem sadri Turkey\check for updates2020ijcua.tif
“SIMURG_CITIES” is the research and development project that is developed under the main project named SIMURG: “A performance-based and Sustainability-oriented Integration Model Using Relational database architecture to increase Global competitiveness of Turkish construction industry in industry 5.0 era”, is a relational database model that is currently being developed in a dissertation for performance-based development and assessment of sustainable and sophisticated solutions for the built environment. This study aims to analyze the key performance indicators (KPIs) at «Cities Level» for the smart city concept that is referred to as «Layers» in the master project. KPIs for the concept of a smart city are determined by using the meta-analysis technique. Hence, the three most reputable urban journals issued from 2017 through 2020 are reviewed in this study. In addition to this, models of smart city frameworks/assessment tools/KPIs are reviewed within the context of this paper; environment, economy, and governance were found to have domain themes on urban sustainability according to the literature review. Consequently, efficient and integrated urban management, environmental monitoring and management, public and social services of urban development, and sustainability are found to be the most important dimensions in urban and regional planning. SIMURG_CITIES evaluation models for urban projects can use the findings of this paper.

ABSTRACT D:\My Journal\papers\Vol 4 ISSUE 1\1 senem sadri Turkey\check for updates2020ijcua.tif
Paris Agreement of December 2015 was the last official initiative led by the United Nations (UN) as the driver of climate change mitigation. Climate change was hence linked with an increase in the occurrence of natural hazards. A variety of initiatives were consequently adopted under different themes such as sustainable cities, climate-friendly development, and low-carbon cities. However, most of the initiatives targeted by global cities with urban areas being the focus in terms of taking action against global warming issues. This is due to the structural and environmental features of cities characterized by being populated, as such, they not only generate a large number of carbon emissions but also happens to be the biggest consumer of natural resources. In turn, they create a microclimate, which contributes to climate change. Masdar City, for example, was designed as the first fully sustainable urban area, which replaced fuel-based energy with electric-based energy. China, as another example, introduced the Sponge Cities action, a method of urban water management to mitigate against flooding. Consequently, architects and urban planners are urged to conform to the proposals that would mitigate global warming. This paper, as a result, examines some of the models that have been internationally adopted and thereafter provide recommendations that can be implemented in large urban areas in Turkey, primarily in Istanbul.

Improving the viability of probiotics by encapsulation methods for developmen...Open Access Research Paper
The popularity of functional foods among scientists and common people has been increasing day by day. Awareness and modernization make the consumer think better regarding food and nutrition. Now a day’s individual knows very well about the relation between food consumption and disease prevalence. Humans have a diversity of microbes in the gut that together form the gut microflora. Probiotics are the health-promoting live microbial cells improve host health through gut and brain connection and fighting against harmful bacteria. Bifidobacterium and Lactobacillus are the two bacterial genera which are considered to be probiotic. These good bacteria are facing challenges of viability. There are so many factors such as sensitivity to heat, pH, acidity, osmotic effect, mechanical shear, chemical components, freezing and storage time as well which affects the viability of probiotics in the dairy food matrix as well as in the gut. Multiple efforts have been done in the past and ongoing in present for these beneficial microbial population stability until their destination in the gut. One of a useful technique known as microencapsulation makes the probiotic effective in the diversified conditions and maintain these microbe’s community to the optimum level for achieving targeted benefits. Dairy products are found to be an ideal vehicle for probiotic incorporation. It has been seen that the encapsulated microbial cells show higher viability than the free cells in different processing and storage conditions as well as against bile salts in the gut. They make the food functional when incorporated, without affecting the product sensory characteristics.
Microbial characterisation and identification, and potability of River Kuywa ...Open Access Research Paper
Water contamination is one of the major causes of water borne diseases worldwide. In Kenya, approximately 43% of people lack access to potable water due to human contamination. River Kuywa water is currently experiencing contamination due to human activities. Its water is widely used for domestic, agricultural, industrial and recreational purposes. This study aimed at characterizing bacteria and fungi in river Kuywa water. Water samples were randomly collected from four sites of the river: site A (Matisi), site B (Ngwelo), site C (Nzoia water pump) and site D (Chalicha), during the dry season (January-March 2018) and wet season (April-July 2018) and were transported to Maseno University Microbiology and plant pathology laboratory for analysis. The characterization and identification of bacteria and fungi were carried out using standard microbiological techniques. Nine bacterial genera and three fungi were identified from Kuywa river water. Clostridium spp., Staphylococcus spp., Enterobacter spp., Streptococcus spp., E. coli, Klebsiella spp., Shigella spp., Proteus spp. and Salmonella spp. Fungi were Fusarium oxysporum, Aspergillus flavus complex and Penicillium species. Wet season recorded highest bacterial and fungal counts (6.61-7.66 and 3.83-6.75cfu/ml) respectively. The results indicated that the river Kuywa water is polluted and therefore unsafe for human consumption before treatment. It is therefore recommended that the communities to ensure that they boil water especially for drinking.
Optimizing Post Remediation Groundwater Performance with Enhanced Microbiolog...Joshua Orris
Results of geophysics and pneumatic injection pilot tests during 2003 – 2007 yielded significant positive results for injection delivery design and contaminant mass treatment, resulting in permanent shut-down of an existing groundwater Pump & Treat system.
Accessible source areas were subsequently removed (2011) by soil excavation and treated with the placement of Emulsified Vegetable Oil EVO and zero-valent iron ZVI to accelerate treatment of impacted groundwater in overburden and weathered fractured bedrock. Post pilot test and post remediation groundwater monitoring has included analyses of CVOCs, organic fatty acids, dissolved gases and QuantArray® -Chlor to quantify key microorganisms (e.g., Dehalococcoides, Dehalobacter, etc.) and functional genes (e.g., vinyl chloride reductase, methane monooxygenase, etc.) to assess potential for reductive dechlorination and aerobic cometabolism of CVOCs.
In 2022, the first commercial application of MetaArray™ was performed at the site. MetaArray™ utilizes statistical analysis, such as principal component analysis and multivariate analysis to provide evidence that reductive dechlorination is active or even that it is slowing. This creates actionable data allowing users to save money by making important site management decisions earlier.
The results of the MetaArray™ analysis’ support vector machine (SVM) identified groundwater monitoring wells with a 80% confidence that were characterized as either Limited for Reductive Decholorination or had a High Reductive Reduction Dechlorination potential. The results of MetaArray™ will be used to further optimize the site’s post remediation monitoring program for monitored natural attenuation.

Water polluted by dyestuffs compounds is a global threat to health and the environment; accordingly, we prepared a green novel sorbent chemical and Physical system from an algae, chitosan and chitosan nanoparticle and impregnated with algae with chitosan nanocomposite for the sorption of Malachite green dye from water. The algae with chitosan nanocomposite by a simple method and used as a recyclable and effective adsorbent for the removal of malachite green dye from aqueous solutions. Algae, chitosan, chitosan nanoparticle and algae with chitosan nanocomposite were characterized using different physicochemical methods. The functional groups and chemical compounds found in algae, chitosan, chitosan algae, chitosan nanoparticle, and chitosan nanoparticle with algae were identified using FTIR, SEM, and TGADTA/DTG techniques. The optimal adsorption conditions, different dosages, pH and Temperature the amount of algae with chitosan nanocomposite were determined. At optimized conditions and the batch equilibrium studies more than 99% of the dye was removed. The adsorption process data matched well kinetics showed that the reaction order for dye varied with pseudo-first order and pseudo-second order. Furthermore, the maximum adsorption capacity of the algae with chitosan nanocomposite toward malachite green dye reached as high as 15.5mg/g, respectively. Finally, multiple times reusing of algae with chitosan nanocomposite and removing dye from a real wastewater has made it a promising and attractive option for further practical applications.

However, the magnitude and significance of a
relationship between land use and congestion
remain unclear. Two major impediments to
statistically sound, comparative studies of land
use and congestion exist a lack of good
measures of congestion; and the difficulty in
modelling the complex interrelationships
between congestion, land use, and transport
infrastructure (Wang, 2010).
Traffic congestion is a comparison of the use of
transportation systems with the capacity of the
transportation system. In a way, land-use affects
traffic congestion in both dimensions. On the
supply side, the street network determines the
number of lane-miles in a given area whereas,
on the demand side, different types of land-uses
will cause variation in travel behaviour (such as
travel frequency, length and mode choice)
which in turn influences the level of congestion
(Ewing & Cervero, 2017). A sizeable number of
studies have investigated the impact of density
development (compact or sprawl) on vehicle-
miles traveled (VMT), traffic volume (e.g. annual
total traffic volume, and volume to capacity
ratio), throughput (e.g. vehicles per hour, and
average daily traffic per lane), travel time and
speed, travel delay, and congestion indices
(e.g. travel time index and roadway congestion
index) (Cervero, 2013; Engelfriet, 2015; Ewing, et
al., 2014; Ewing, et al., 2018). However, these
studies have reported mixed links between
density and traffic congestion measures.
In response to the new urbanism and compact
city concepts, developments with diverse uses
are strongly thought to maintain sustainability
and reduce car dependency (Kusumastuti &
Nicholson, 2017). There is relatively strong and
significant empirical evidence that diversity
reduces the individual VMT (Cervero, 2013;
Geyer & Quin, 2019; Spears, Houston, & Boarnet,
2013). A balance between jobs and housing
might reduce the length of commute trips thus
reducing traffic congestion and air pollution.
Scholars have been arguing that the reasons for
the continued lengthening of commuting times
and the marked deterioration of traffic
conditions are the results of the increasing job
and housing imbalance in many metropolitan
areas (Niedzielski, O'Kelly, & Boschmann, 2015;
Zhang et al., 2017). A community is considered
balanced when residential and employment
distributions are approximately equal
(Jiangping, Chun, Xiaojian, Wei, & Peng, 2014;
Masoumi et al., 2018; J. Zhou & Long, 2014).
Areas with diverse uses are found to significantly
increase slow modes shares, increase walk
mode choice for work trips (Ton, et al., 2019)
and non-work trips (W. Zhou & Li, 2016). The
proximity of commercial centers to the
residence location has a strong impact on
increasing the walk mode share for non-work
trips (Alqhatani, Setunge, & Mirodpour, 2014).
Regarding public transport (transit), similarly,
empirical evidence is found in the literature
about the positive impact of the land-use
mixture in promoting the frequency and mode
share of public transport. Numerous scholarly
efforts have observed that walking distance
and walking time are critical factors in
determining mode choice (for example
whether to use public transport or not) (Durand
et al., 2016; Ewing & Cervero, 2010; Grisé, Wasfi,
Ross, & El-Geneidy, 2019). A plethora of studies
has investigated whether urban design increase
or reduce traffic congestion (Ewing & Cervero,
2010). Household VMT could be significantly
reduced with an increase in bicycle lane
density or with an increase in intersection
density (Litman, 2012). In contrast, residential
areas with a high proportion of intersections are
empirically found to provide pedestrian-friendly
land-uses. These areas significantly increase the
active transport trip frequency and increase the
probability of the walk mode choice for work
and other trips alike
Another body of research investigated the
impact of destination accessibility on traffic
congestion (Ewing & Cervero, 2010; Hasibuan,
et al., 2014; Suzuki, et al., 2013). A development
toward a more sustainable transport system (as
in increasing walking, cycling and public
transport, and decreasing car-use) has been
regarded as an important aim in the field of
transportation research in the last decades due
to an array of reasons, including environmental
issues and congestion. Therefore, the objective
of this literature review is to present current issues
surrounding the interaction between land-use
and traffic congestion. For this purpose, a
systematic literature review published from 2010
to 2020 is carried out. A systematic literature
review was chosen due to its transparent and
replicable characteristics, and its identification
of research gaps and occurrence for further
investigation. This review analyses the literature
from a descriptive standpoint, to assess
advancement and emphasize the areas of
further research required. Thus, this study aims to
answer the question: what sort of a relationship
3. JOURNAL OF CONTEMPORARY URBAN AFFAIRS, 5(1), 77-84/ 2021

exists between land-use and traffic congestion?
For this purpose, the present review is organized
as follows: Section 2 presents the methodology
followed by Section 3 which presents the results
of the investigation. Section 4 presents the
discussion of the topic, section 5 presents the
research gap, section 6 presents limitations and
future research and finally, Section 7 presents a
brief conclusion.
2. Methodology
To provide a vigorous review of the literature we
performed a systematic review on the
relationship between land-use and traffic
congestion. The inclusion criteria were (i)
publications indexed in Elsevier, ScienceDirect
and JSTOR databases, (ii) publication date
between 2010 and 2020 (iii) written in English,
and (iv) particular search terms covered.
Editorial material, books, or book chapters,
technical reviews were excluded from our
research. We employed the Systematic Review
Data Repository (SRDR), a cutting-edge tool for
extraction, administration and inspection of
data for our systematic review. Gathering and
analysing publicly accessible literature we
required no institutional ethics approval before
initiating our research. During the period August
2019 we conducted a quantitative literature
review of Elsevier, ScienceDirect, and JSTOR
databases, with search terms including “land-
use” and “traffic congestion” Out of 436 papers
found, dated from 2010 to 2020, only 45 articles
met the eligibility criteria. These articles were
analysed and classified according to different
categories based on their characteristics.
Descriptive analysis was adopted and it
included the geographical framework and
research methodologies being used. Fig 1
depicts the sequence of steps undertaken for
this research methodology.
Figure 1. The sequence of steps taken for this research methodology.
3. Results
The results comprise of descriptive analysis of
the 45 articles. The descriptive analysis consists
in identifying and classifying the articles by
geographical framework and analysis of
research methodology.
3.1 Analysis of articles by the geographical
framework
Table 1 shows the geographical framework of
articles used to analyse the interaction of land-
use and traffic congestion.

The geographical distribution shows that the
American continent dominates research on
land-use and traffic congestion. For instance,
Wang (2010) used a multi-dimensional
approach to measure the impact of land-use
and traffic congestion in Florida. Kuzmyak
(2012) performed a detailed analysis of the
relationships between higher-density land-use
and traffic conditions in four Phoenix
transportation corridors in the United States.
Using aggregated commute data from the
American Community Survey, Gordon and Lee
found that job dispersion, rather than just density
or population dispersion is the critical factor for
congestion and travel time. Ewing, Keith, et al.
(2018) conducted a study in the United States
and found that compact, mixed-use
development is inherently more efficient and

private vehicle use rates by bringing people
and activities closer together, and also
providing densities that are capable of
supporting walking and effective transit
services. Adetunji (2020) stated that as
population increase, the number of
automobiles, tricycles, and motorcycle also
increase.
Some notable studies conducted in Asia
include a study conducted by Patel, Kheni,
Patel, Patel, and Chauhan (2019) who
evaluated traffic congestion using a
comparative land-use pattern in Surat, India,
and found that land-use impacts the
movement of traffic. Zhang et al. (2017)
proposed a new method to describe, compare,
and classify the traffic congestion points in
Beijing, China, using the online map data and
further revealed the relationship between traffic
congestion and land-use. Shubho and Neema
observed that careless unplanned
development of land-uses in Dhaka,
Bangladesh has resulted in perpetual traffic
congestion along with pollution, thereby
aggravating its sustainability. Mukherjee et al.
(2014) carried a study to determine the effects
of heterogeneity in land-use distribution on
traffic congestion in rapidly urbanising Ranchi
City, capital of Jharkhand state, India and
found that there is a positive relationship
between heterogeneity in land-use distribution
and traffic congestion. There is a paucity of
studies on the research topic in the African
continent. The only study obtained from the
search was a study by Oduwaye, Alade, and
Adekunle (2011) who surveyed the land-use
and pattern along the Lagos-Badagry corridor,
in the Lagos metropolis, Nigeria.
3.2 Analysis of Research Methodologies
This sub-section presents a comprehensive
analysis of the methodologies that were used to
uncover the relationship between land-use and
traffic congestion. Although a consensus has
been reached on the interaction of land-use
and traffic congestion, the magnitude and
significance of a relationship between the two
are still unclear suggesting that there might be
inconsistencies in the methods used to analyse
this topic. The differences in conceptual models
in previous studies are likely to generate
contradictory results. For instance, land-use is
measured in different ways (Newman &
Kenworthy, 2015) and so is congestion (Rao &
Rao, 2012). Ewing, et al., (2018) assert that no
one has yet determined, using credible land-
use metrics and credible congestion data, the
net effect of those countervailing forces on
area-wide congestion. Cutsinger et al., (2010)
points that there are eight dimensions of the
metropolitan structure, namely: density,
continuity, concentration, clustering, centrality,
nuclearity, mixed uses, and proximity.
Ewing et al. (2014) used the
compactness/sprawl index metrics
methodology to measure sprawl in 162 U.S
urbanised areas. Following the same logic,
Sarzynski, Galster, and Stack (2014) explored the
multi-dimensional variations and changes in U.S.
metropolitan land-use patterns during the
1990s. Jaeger and Schwick (2014) have
conducted analyses extending the time
considerably. They developed a Weighted
Urban Proliferation (WUP) metric to assess urban
sprawl in Switzerland and present for the first
time quantitative figures about the
development of sprawl for an entire country
over a time of more than a century. Their
method is suitable for studying changes in
regional sprawl patterns over time and offers
valuable tools for analysing the changing
nature of sprawl and urban development
historically. European Environmental Agency
used urban permeation (UP) and WUP as sprawl
metrics for all European countries. Fuladlu (2019)
that urban sprawl does not promote auto-
dependency.
Cutsinger et al., (2010) used a multidimensional
conceptualization of land-use to prove to be an
important improvement. Cervero (2013)
conducted a cross-sectional study design with
Structural Equation Modelling (SEM). Using
compactness/sprawl metrics they found that an
increase in compactness reduces the amount
of driving people to do, but also concentrates
the driving in smaller areas. Using data from 45
county-level urban areas of 2007 in the State of
Florida, Wang (2010) measured 12 indices of
land-use and 3 measures of traffic congestion,
grouping them into 5 distinct factors and
conducting bivariate analysis between
variables. Kuzmyak (2012) used the volume to
capacity ratio (V/C ratio) to measure
congestion and density, diversity, and
destinations to measure land-use.
In light of the articles reviewed, it clear that
there is a lack of consensus on the credible
variables, congestion data used, population
size, and consideration for reverse causation
and time-lags. This lack of consensus suggests
5. JOURNAL OF CONTEMPORARY URBAN AFFAIRS, 5(1), 77-84/ 2021
Phd Candidate James Kanyepe, Prof. Dr. Marian Tukuta & Prof. Dr. Innocent Chirisa 81
that further refinement of the models may be
necessary, paying special attention to these
methodological issues.
4. Discussions
This study conducts a literature review of articles
on land-use and traffic congestion, published
from 2010 to 2020, in Elsevier, ScienceDirect,
and JSTOR databases. This research investigates
the available literature under several
constraints: Time period, English language,
three database sources, research and literature
articles only with different variants on search
keywords, and land-use and traffic congestion
emphasis. Furthermore, this research classifies
the extracted articles under different
approaches: Distribution of articles by the
geographical framework and research
methodology, and tools and techniques used
for analysis. The results of these classifications
have facilitated the discussion on the current
status and progress on traffic congestion and
land-use. Therefore, the key findings will be
discussed, followed by the research gaps and
future research opportunities.
Policymakers, including transport planners and
transport engineers, have become increasingly
aware and interested in understanding the
interaction between land-use and traffic
congestion. However, there is a paucity of
research on the research topic in developing
countries. Out of 45 articles used for this study,
the American continent had 44%, followed by
Asia (26%), Europe (21%), and Australia (8%)
whereas African had less than 1% of the articles.
The study also revealed that the United States
has been the major contributor to land-use and
traffic congestion articles, followed by China,
Bangladesh, Europe, and Nigeria. The study
revealed that linear regression is the most used
technique (21 articles) followed by correlation
analysis (17 articles) and the least used
approach is Structural Equation Modelling (SEM)
(7 articles), Ewing, Tian, and Lyons (2017) used a
cross-sectional study, regression analysis along
with Structural Equation Modelling. Kuzmyak
(2012) developed a set of regression models to
quantify the effects of key land-use variables on
household vehicle ownership and VMT,
illustrating the mitigating effects of higher
density, better mix, and better transit
accessibility.
Density is the most commonly used measure of
land-use. From the articles used, 87% used
density, design, and diversity concerning traffic
congestion. Wang (2010) adapted the multi-
dimensional approach to measure land-use
and traffic congestion. He obtained data
obtained from 45 county-level urban areas as of
2007 in the State of Florida. In the conceptual
model, he developed three (3) congestion
indicators – Roadway Capacity Index (RCI),
Travel Time Index, and delay per capita, which
were correlated with twelve (12) land-use
measures, grouping urban form indices into 5
distinct factors, and conducting bivariate
analyses between variables. Zhang et al. (2017)
used linear regression analysis to determine the
influence of the high proportion of commercial
land-use on traffic congestion. The findings
show that there are studies on land-use and
traffic congestion in developing countries
particularly in Africa are scarce. Furthermore,
the study findings show that there are
inconsistencies in the methods that were used
to analyze the topic.
5. The Research Gaps
The current body of knowledge lacks empirical
insights into the interaction between land-use
and traffic congestion in developing countries.
There has been inadequate attention to and
discussion on how land-use influences traffic
congestion in developing countries. However, a
great amount of literature-based evidence on
the research topic is abundant in developed
countries but findings from these studies have
been refuted based on methodological
concerns. For instance, a sizeable number of
scholars have focused on how density
influences traffic congestion but the influence
of other measures of land-use (such as diversity,
design, destination accessibility, and distance
to transit) on traffic congestion is scarce.
Besides, previous studies have used basic
measures of traffic congestion and obtained
varying results. For example, Kuzmyak (2012)
used volume capacity (V/C ratio) and found
that that there was considerably less congestion
despite densities that were many times higher in
four Phoenix transportation corridors in the
United States of America while Zhang et al.
(2017) used commute time and found that a
reasonable ratio of land-use could efficiently
reduce traffic congestion. However, studies
exploring the interaction between land-use and
traffic congestion using a multi-dimensional
approach are limited. Therefore, it is important
to address the deficiencies exhibited by basic
6. JOURNAL OF CONTEMPORARY URBAN AFFAIRS, 5(1), 77-84/ 2021
Phd Candidate James Kanyepe, Prof. Dr. Marian Tukuta & Prof. Dr. Innocent Chirisa 82
measures through the use of a multi-
dimensional approach.
6. Limitations and Future Research
This sections present limitations and further
research opportunities. The restriction of
database access availability has limited the
research and thus articles from other sources of
primary importance on the interaction between
land-use and traffic congestion could have
been excluded from processing. The keywords
used may not be all-inclusive. The review was
carried out on 45 articles; therefore, the
exploration of more articles could broaden the
conceptualization and knowledge of empirical
research, and issues currently addressed
regarding land-use and traffic congestion. The
land-use dimensions that influence traffic
congestion have not been studied in the same
magnitude particularly in developing countries.
Besides, a plethora of research has not yet
agreed on the proper methodology to use
when examining the interaction between the
two. Likewise, the current body of literature on
the research topic can be criticised for a lack of
insight into the aspects that make a good
congestion measure. For example, commute
time computes travel time across different
travel modes; ADT/lane and commute time are
averaged numbers across time and space
while delay per capita is limited to peak hours
and only for arterial and freeways. Therefore,
research on the interaction between land-use
and traffic congestion must evolve from these
basic indicators and use multi-dimensional
measures. Moreover, by increasing the number
of articles, more specific topics can be
analysed and trends can be identified with
greater precision. Furthermore, there is a need
to segregate empirical research for developed
and developing countries due to intrinsic
differences that may result in distinctive findings.
7. Conclusions
Research on the interaction between land-use
and traffic congestion in developing
economies has begun and advanced in the last
two decades, however it is still in its infancy
when compared to research in developed
countries. This study attempted to enrich the
knowledge of the research field by carrying out
a literature review of articles available on
specific databases in the last decade. The
undertaken different approaches classification
and analysis of the selected papers helped to
provide and discuss outcomes on current
research status. Although a consensus has been
reached on the interaction of land-use and
traffic congestion, the magnitude and
significance of a relationship between the two
are still unclear thus a critical knowledge gap
that needs to be filled. The ongoing debate with
regards to the significance of the relationship is
intensified by inconsistencies in methodological
approaches, lack of multi-dimensional
measures for both land-use and traffic
congestion. Further research can be directed
toward addressing these issues. It is also
recommended to conduct a study on the topic
in developing countries as far less is known on
this subject.
