APPLICABILITY OF CROWD SOURCING TO DETERMINE THE BEST TRANSPORTATION METHOD B...IJDKP
Traffic is one of the most significant problem in Sri Lanka. Valuable time can be saved if there is a proper way to predict the traffic and recommend the best route considering the time factor and the people’s satisfaction on various transportation methods. Therefore, in this research using location awareness applications installed in mobile devices, data related to user mobility were collected by using crowdsourcing techniques and studied. Based on these observations an algorithm has been developed to overcome the problem. By using this, the best transportation method can be predicted as the results of the research. Therefore, people can choose what will be the best time slots & transportation methods when planning journeys. Throughout this research it has been proven that for the Sri Lankan context, the data mining concepts together with crowdsourcing can be applied to determine the best transportation method.

A low cost method of real time pavement condition data sharing to expedite maintenance intervention
Pavements for roads in cities and highways are degraded with potholes, cracking, and rutting distresses. There is a strong need to identify these locations and sections with undesired longitudinal roughness quickly and accurately every year. Traditionally, expensive standalone survey vehicles for roughness measurements and more expensive multi-function vehicles are employed by highway agencies or through contract services, which most cities and local agencies can’t afford. The primary objective of this study is to describe a low cost method to collect essential pavement condition data and share real time to expedite maintenance intervention needs. This facilitates rapid identification of pavement sections with undesired longitudinal roughness and local defects. This paper discusses the impact of social media, crowd sourcing, and advances in cheaper accurate motion sensors and cloud server data processing. These tools make it possible to develop easy-to-use low cost methods, which are affordable by city public work and smaller road agencies.
The Kentucky Transportation Cabinet developed a statewide public roadway centerline database in the late 1990s to improve transportation data and analytics. Area Development Districts were contracted to collect centerline data using GPS. This data serves as the foundation for other state and federal transportation databases and systems. The database has been refined over time and now contains over 360,000 road segments. It is updated weekly with state roads and biweekly with local roads to support 911 systems and local initiatives. Collaboration between state and local agencies has been important for maintaining an accurate statewide transportation network.
Design of Highway with Major Bridge on Stagnant WaterIRJET Journal
This document summarizes a research paper that designed a highway and major bridge project in India. It analyzed traffic patterns and soil conditions to design sustainable pavement that meets standards. Hydraulic studies of a river were also conducted to design a safe bridge. The project included a 6-lane highway in Maharashtra, India. Traffic surveys found the soil CBR was low, so cement treatment of the sub-base was recommended. The bridge design considered hydraulic catchment of the dam. Economic analyses aimed to identify the most cost-effective design options.
This document discusses a mobile app called "Road Factor" that uses GPS to provide information on road conditions. It allows users to view details of the road they are currently on, like when it was last resurfaced. Government agencies can use the data to monitor roads and make planning/budget decisions to improve road maintenance. The app aims to help build better transportation infrastructure and facilitate governance through electronic monitoring of roadwork. It connects to a centralized database containing road condition details for cities across India.

This document discusses dynamic resource allocation in the road transport sector using mobile cloud computing techniques. It provides an overview of existing literature on dynamic resource allocation methods and their limitations in addressing high vehicle and route demand fluctuations. The document then proposes using mobile cloud computing to allow for real-time vehicle-route allocation with minimal processing time by installing mobile devices at stations to communicate demand data to nearby clouds and a central traffic manager for computation and order distribution. Simulation case studies are developed and results are compared to real data to validate the mobile cloud computing approach for improved dynamic resource allocation under heavy demand fluctuations.

Literature review revealed application of various techniques for efficient use of existing resources in road transport sector vehicles, operators and related facilities. This issue assumes bigger dimensions in situations where there are multiple routes and the demand in the routes is highly fluctuating over the day. The application of the existing techniques as reported in literature addresses above issues to a considerable extent. However the main draw back in existing techniques is lack of
proper uninterrupted information about vehicles and demand available at a central place for allocation of vehicles in different roads and huge computational times required for processing. Cloud computing is a recently developed processing tool that is used in effective utilization of resources in transport sector under dynamic resource allocation.

Intelligent Traffic Management System using Shortest Pathijtsrd
Due to current significant increases in population and consequently in traffic congestion in most metropolitan cities in the world, designing of an intelligent traffic management system ITMS in order to detect the path with the shortest travel time is critical for emergency, health, and courier services. The aim of this research study was to develop a theoretical traffic detection system and capable of estimating the travel time associated with each street segment based on the traffic data updated every 20 seconds, which successively finds the path with the shortest travel time in the network by using a dynamic programming technique. Furthermore, in this study we model the travel time associated with each street segment based on the historical and real time data considering that the traffic speed on each road segment is piecewise constant. It would be useful to implement such algorithms in GIS systems such as Google map in such a way that the service delivery drivers can avoid congested routes by receiving real time traffic information.

IRJET- Bus Route Optimization in Jyothi Engineering College using ARC- GISIRJET Journal
This document discusses optimizing bus routes in Jyothi Engineering College using ArcGIS. It involves collecting data on the existing bus routes, digitizing the routes and roads on a map of Thrissur district. Attributes like distance, time and passenger demand at stops are added. Network analysis using ArcGIS Network Analyst is then used to analyze if the current routes are optimal in terms of distance and time or if alternative optimized routes can be suggested. The analysis found the existing routes to be optimal given the demand. Fully optimizing each route would require separate analysis using vehicle routing problems, but potential alternative routes had less demand, so would not be profitable.

1. Keeping Traffic Moving
during Bridge Repair Project
By Matthew DeMeritt, Esri Writer
With 12 percent of US bridges declared structurally
deficient by the Federal Highway Administration in
2006, bridge repair remains a top priority for most
states. Three years before that, an extensive in-
vestigation of Oregon’s bridges conducted by the
Oregon Department of Transportation (ODOT)
found that 365 of Oregon’s bridges had structural
problems that necessitated a large-scale bridge
repair plan. Implementing that plan required that
the department expand its GIS infrastructure and
integrate a new traffic modeling application to
ease congestion at multiple construction zones
along the state’s highway system.
Oregon Transportation Investment Act
From 2001 to 2003, Oregon passed a series of funding
packages called the Oregon Transportation Investment
Act (OTIA I, II, and III) to improve its highway infra-
structure. For OTIA III, which included the State Bridge
Delivery Program, ODOT turned to engineering consult-
ants Oregon Bridge Delivery Partners (OBDP), a joint ven-
ture between HDR Engineering and Fluor Corporation,
to create practices that would ensure the project finished
successfully and within budget. One of the primary goals
of the program was to reduce the impact on commuter
and business traffic during large-scale construction on
its road system.
Many of the bridges designed during the early devel-
opment of Oregon’s highway system used a reinforced
concrete deck girder (RCDG) design specified in the
regulations of that time. As specifications became
more stringent in the 1960s, Oregon transitioned to pre-
stressed and post-tensioned concrete bridges that im-
proved structural integrity at a reduced cost. However,
many RCDG bridges remained in service well past
their expected decommission date and began to show
signs of deterioration on deeper investigation. “In 2001,
ODOT inspectors noticed that cracks identified in previ-
ous inspections had grown to the point of threatening

structural stability,” said Jim Cox, assistant manager of
major projects at ODOT. “We immediately placed load
restrictions on these bridges and started discussion on
how to plan repairs with the least impact on commercial
and commuter traffic.”
GIS and Geodesign
Established in 2004, ODOT’s GIS comprised the depart-
ment’s information-sharing infrastructure to plan and
manage roadway projects. To integrate with ODOT’s
GIS, OBDP designed its system on the same ArcGIS plat-
form for flexibility and scalability throughout the pro-
ject life cycle and beyond. “We wanted easy adoption of
tools and practices to smooth transition during project
closeout and ensure usefulness beyond that,” said Robb
Kirkman, GIS Services manager for HDR Engineering.
“GIS provided the foundation to start linking program
systems, automate tasks, and better mitigate environ-
mental impacts.”
Before any construction work began, ODOT collected
comprehensive environmental data on more than 400
of its bridge sites to identify nearby environmental
resources. Standard ODOT practice involves consulta-
tion with experts such as biologists, wetland specialists,
and archaeologists to get a better understanding of the
effects of construction zones in ecologically sensitive
areas. “We took a different approach for the OTIA III
Bridge Program by conducting environmental fieldwork
before we did any design,” said Cox. “In ArcGIS, we drew
a box around a bridge site and identified all the resources
inside the box. This allowed the engineers to develop
designs that minimized impacts on the surrounding
environment.”
Improving Work Zone Traffic Analysis
Prior to its collaboration with OBDP, ODOT had been
using spreadsheets containing traffic counts and auto-
matic traffic recorder information from across the

state to document and predict traffic impacts for its
various road construction projects. That process could
take up to four hours for each scenario because data had
to be searched and collected from multiple databases
within the agency and then inserted into a spreadsheet.
“Gradually, that process evolved to incorporate GIS pro-
cesses,” Kirkman said. “Using macros and automation
tools in ArcGIS, ODOT’s traffic group was able to auto-
matically populate the spreadsheets with information
from the database.”
Although much leaner, the spreadsheet-only approach
experienced crashes as the database grew ever larger.
The traffic team worked with OBDP to develop a more ef-
ficient GIS-based method for running traffic scenarios—
one that tightly wove ODOT’s geospatial data into a dedi-
cated web-based analysis tool. Using common protocols,
they worked on tying the datasets together to give ODOT
staff direct access to the department’s databases from a
single interface. Called the Work Zone Traffic Analysis
(WZTA) tool, the application allowed traffic scenarios to
be run and shared in a web browser.
WZTA serves as a repository for information on traf-
fic and road data that can be accessed and queried in
a browser. The system allows users to view ODOT data
to determine the effects on mobility created by lane
closures related to construction and roadwork. Today,
the department can run traffic scenarios in a matter of
minutes, eliminating redundancy and enabling ODOT
engineers to modify traffic plans on the fly.

ing systems aren’t intuitive to all users,” Kirkman said.
“GIS enabled users to find exactly what they were looking
for and verify the correct project information within a
more appropriate map-based user interface where spa-
tial relationships are more obvious.”
Documented Return on Investment
In 2010, ODOT and OBDP documented their experi-
ence with the tools to evaluate the impact of ODOT’s

investments and determine if they should be used after
completion of the bridge program. With the assistance
of economic consultant Mark Ford, they analyzed every
piece of software OBDP created for the OTIA III Bridge
Delivery Program to determine the economic benefits and
cost to the department. The study concluded that ODOT
experienced a combined benefit-cost ratio of 2:1 for all
enterprise IT investments related to management of the
bridge program.
ODOT’s GIS infrastructure alone returned a benefit-
cost ratio of 3:1. “Integration of formats and standards
proved to be important in generating value from the in-
vestment,” said Ford.
In addition to these tangible benefits, ODOT experi-
enced three types of intangible benefits. Migrating the
data from disparate sources into a unified system allowed
OBDP to employ consistent analysis methods, reducing
the risk of calculation errors. The centralized database
also made it easier for ODOT to maintain data integrity
and reduce the risk that analysts working at different lo-
cations could use outdated information. “Systems like
ODOT’s GIS infrastructure generate accurate, consistent,
and timely information for reporting and responding to
inquiries,” Ford said. “WZTA, and GIS in particular, has
resulted in improved coordination with other agencies
and interest groups, increasing the credibility of both
ODOT and the bridge program in the eyes of the public
and the legislature.”
At the beginning of 2011, 351 of the 365 bridges in the
OTIA III Bridge Delivery Program were free of construc-
tion zone delays. WZTA played a primary role in expedit-
ing the construction process by allowing the team to run
lane closure traffic analyses in minutes as opposed to
hours. The tool is now being used by ODOT on other road-
way maintenance and construction projects to quickly
determine impacts from lane closures across the state.
Using a GIS-based interface, ODOT analysts can select the location and other information for a specific project
site from the map itself rather than tabular lists. In 2007, WZTA received the Team Excellence Pathfinder Award
from the American Association of State Highway and Transportation Officials.
