Abstract
Mass Rapid Transit is one of the major Transportation system proposed in metropolitan city like Bangalore in order to be beneficial
in reducing various traffic problems and result in reduction of Travel time etc. The efficiency of this system can be increased by
attracting more number of Trip makers by a suitable Integrated Transport System. Feeder system is one of these techniques proposed
for Namma Metro in Bangalore which includes Feeder bus (Minibus) operating throughout the radial areas of Metro stations. The
present study includes the necessity of these buses as par with Public Transport Buses currently operating in these areas with respect
to the willingness of commuters, Frequency and Travel Time.
At present, there are many problems being faced by road users in urban area with limitation of land space and traffic congestion, pedestrian are one of the most vulnerable entities of the transportation system It is observed that there is an increase in number of conflicts between pedestrian and the vehicles in the city. In order to mitigate the conflicts between vehicular traffic and pedestrian traffic an attempt is made to provide a Skywalk. The present study involves the Opinion survey of pedestrians, Mid-block traffic count, pedestrian count were carried out for Ashoka road on weekdays and weekends. From the opinion survey, traffic count and pedestrian counts we can conclude that there is a need to construct Skywalk to reduce the pedestrian accidents rates on Ashoka road.
Designing of a Traffic Signaling System at T-IntersectionIJERA Editor
The traffic signal design of the intersection has a direct control on its safety and operation from a design and user-ability point of view. We identified Kothavalasa T-Intersection has been arise problems like road accidents, conflicts and congestions. Design elements that are particularly important include the number of lanes provided on each approach and for each movement. These problems can solve by providing an efficient traffic signal control at the intersection for continuous movement of vehicles through the intersection. According to traffic signal, most traffic signal timing plans are designed to minimize vehicle delay based on the volumes seen in the past, not the present. Traffic count studies are to be made to determine the number, movement and classification of vehicles at an intersection. Signal timing is most important which is used to decide green time of the traffic light shall be provided at an intersection and how long the pedestrian walk signal should be provided. By using Highway Capacity Manual (HCM) intersection saturation for identifying periods of time when cycle length could be substantially short. These data is used identify normal flow of the roadway; determine the influence of heavy vehicles or pedestrians on vehicular traffic volume. Webster’s minimum delay cycle length equation overestimates the optimal cycle length compared to the results based on the HCM 2000 method. This is due to the restructuring of the HCM 2000 delay equation as compared to the original Webster’s delay calculation.
Study the Effects of Traffic Situation on Driver’s Mood and Root Choice Decis...ijtsrd
A traffic management system is essential for better mobility in terms of cost, safety, comfort, and time savings, among other factors. A traffic management system assures the safety of not only car occupants but also pedestrians crossing the road. The work primarily focuses on analysing traffic volume using software and manual counts on two types of roads, namely broad lane and service lane. This study comprises using the Picomixer STA Smart Traffic Analyzer programme to count the number of different types of vehicles, which are classified as light vehicles Cars, SUVs, etc. , medium loading vehicles trucks, minibuses , and heavy vehicles Trucks, Minibuses, etc . Trailers, Big trucks etc. .On the broad lane, traffic peaks during the day and at night, while it remains light and medium during the middle of the day. This trend also affects the rush in the service lane, which follows a similar pattern. Increased traffic and longer signal halt times encourage drivers to use the alternate service lane, which increases congestion in the narrow service lane and raises the danger of accidents. Longer signal halts were discovered to be the most important factor to consider when choosing a service lane. Reduced signal timing can have an impact on typical service lane and broad lane utilisation, as well as traffic management.

Determination of congestion charge for car users in cbd area of thiruvanantha...eSAT Journals
Abstract Congestion is a situation in which demand for road space exceeds supply and is characterized by slower speeds, longer trip times, higher transportation costs and increased vehicular queuing. Thiruvananthapuram, the capital city of Kerala, is the second largest and most populous city in the state.The roads and neighbourhoods of the city experiences more chronic congestion and serious crashes than ever before due to higher share of personalized transport and para-transit modes in traffic stream. The present study conducted in Central Business District (CBD) area of Thiruvananthapuram city. The periods of peak congestion in Thiruvananthapuram now last for 4 hours from 8.00 to 10.00 in the morning and from 4.00 to 6.00 in the evening. In this paper, an attempt has been made to assess the congestion level experienced on major road corridors of the city and to determine congestion charge for car users in Mahatma Gandhi Road, which is the most congested road corridor of Thiruvanathapuram city. The method used for the determination of optimal pricing is related to the point of pricing where the external costs are met by the revenue generated by the pricing level. Keywords: Congestion pricing, External costs of congestion, Travel time, Demand elasticity.
Focused on the lane occupancy phenomenon, this paper analyzes the roads during two different accidents to the evacuation period. Firstly, according to the statistical data, this paper calculated the correction coefficients under the road traffic condition, and then obtained the actual traffic capacity result at each moment of the road when combining the function model of the actual traffic capacity corrected by the running speed and the road traffic condition. Next the actual traffic capacity results are fitted to the Smooth spline interpolation, and then the actual traffic capacity is further verified by the traffic congestion situation. The actual traffic capacity of the road during the accident to evacuation is summarized as follows: the actual traffic capacity shows a nonlinear trend, that is, ascending-attenuating-recovering and gradually stabilizing. Finally, using Mann-Whitney U test to carry out the difference test on the actual traffic capacity, it is found that there is significant difference between the two groups of data, and the actual traffic capacity of the second case is stronger than that of the first one, and the reasons for the difference are analyzed as follows: the ratio of the steering traffic volume at the downstream intersection is different; this road section includes the community intersection and there are vehicles entering and leaving; meanwhile the speed of each lane is different and there are buildings near the lane. The above conclusions will provide theoretical basis for the traffic management department to correctly guide the vehicle driving, approve the road construction, design the road channelization plan, set the roadside parking space and the non-port-type bus stations.

A STUDY ON GAP-ACCEPTANCE OF UNSIGNALIZED INTERSECTION UNDER MIXED TRAFFIC CONDITIONS S.Siva Gowri Prasad1, Ramesh Surisetty2, Suresh Kumar ch3 1Assistant professor, Department, of Civil Engineering, GMRIT, Rajam, A.P India 2Post graduate student, Department of Civil Engineering, GMRIT, Rajam A.P India 3Post graduate student, Department of Civil Engineering, GMRIT, Rajam A.P India Abstract Unsignalized intersections are the key elements in urban streets and in rural road networks. The methodology for the analysis of unsignalized intersections has been established where homogeneous traffic conditions are dominated, there are several attempts made to develop different approaches for the analysis of unsignalized intersections under mixed traffic conditions. Conflict technique is a recent development, which is based on pragmatically simplified concept, considering interaction and impact between flows at intersection. In present study, capacity of unsignalized intersection was calculated from Conflict technique. Surveys were conducted in Visakhapatnam, to measure different traffic parameters such as volume, flow $ capacity to this method. Movements of capacity were evaluated by HCM (2000) by comparison with approach wise capacities obtained from conflict technique. Keywords: Unsignalized Intersection, Surveys, Traffic Parameters, Tanner’s Model, Capacity, Conflict technique.
--------------------------------------------------------------------***----------------------------------------------------------------------- 1. INTRODUCTION An intersection is a node, and usually it is a block of traffic flow in highway network. Capacity of a intersection affects the total capacity of highway network due to all types of turning movements. For actions of conflicting, merging and diverging caused by traffic flow, the traffic characteristics of intersection are more complex than those of road mid block section. Traffic stream in developing countries comprises of different types of motorized and non-motorized vehicles leads to mixed traffic conditions and lane changing patterns. Urban roads in India carry different types of vehicles like high speed automobiles, low speed cycles, cycle rickshaws and animal drawn carts. This will lead to complex interaction between the vehicles and study of such traffic behavior needs special attention. The traffic plying on roads in western countries is of characteristics of different vehicles with marginal variation contrary to large variation on Indian roads. This will result in increased interactions between vehicles; then they tend to move in clusters rather than one after the other. Further two or three wheelers such as scooters, cycles, and cycle rickshaws contribute to this because of their easy maneuverability.
The traffic on Indian roads consists of bi-directional freedom traffic such as two or three wheeled vehicles and uni-directional vehicles such as four wheelers. While the above tend to overtake or turning or crossing or turn right even if a small gap is available. Hence, to determine the intersection capacity traffic engineer requires a clear understanding of gaps being accepted or rejected by various modes of traffic. Besides, in these mixed traffic conditions, users do not usually follow lane discipline and can occupy any lateral position on the road. Under these conditions, capacity of an unsignalized intersection is difficult to be determined and becomes a very interesting field of highway capacity study. There are several types of capacity analysis models for unsignalized intersections. The third approach is the conflict technique which was based on the mathematical formulation of interaction and impact between flows at an intersection. Aldian et.al (2001) [1] examined the suitability of some traffic models to determine U-turn capacity at median openings. Ian C. Espada et.al (2002) [2] deals with the development of a priority intersection Capacity Formula that is sensitive to control type. Ning WU (1999) [3] performed a simplest configuration with one Major stream and one Minor stream and a new universal capacity formula is introduced. Tian et.al (1999) [4] showed that most of the capacity calculation procedures for two-way stop-controlled (TWSC) intersections are based on gap acceptance models. Wan Hashim et.al (2007) [6] showed that Critical Gap Acceptance procedure is still widely used for estimating capacity of unsignalized intersection. Werner Brilon et.al (1996) [7] deals with the capacity of minor traffic movements across major divided four-lane roadways (also other roads with two separate carriageways) at unsignalized intersections. Werner Brilon et.al (1997) [8] has performed a series of comprehensive simulations of some of the estimation methods. 1.1 Objectives

To know the priorities an intersection/junction by using Mathematical Model.
1.2 Study Area The major traffic conflicts occur at T-Intersections are identified in Visakhapatnam:
Urvasi Junction
Kancharpalem Junction
Gnanapuram Junction
Figures 1, 6 and 11 shows the pictorial representation of three Junctions 2. DATA COLLECTION The study of traffic behaviour is useful for traffic engineers to design intersections, for developing traffic control warrants, traffic signal timings, to design the vehicle storage lanes. Data is needed for analysis and understanding of the traffic conditions. The data can be collected by manual method. 2.1 Requirements The main objective of this study is to find the capacity of unsignalized intersection using conflict technique and to compare the results with the HCM (2000) procedure, which is based on the gap acceptance procedure. For this the following field observations are necessary.
Travelled distance for each movement on each approach.
Times of arrival and departure at reference lines for each vehicle from each stream.
Approach speed of the vehicles.
Volume at unsignalized intersection movement- wise.
Manual counts are typically used to gather data about the following:
Vehicle classifications
Turning movements
Direction of travel
Pedestrian movements
Vehicle occupancy
The number of people need to collect data depends on the length of the count period, type of data being collected, number of lanes or cross walks being observed, and traffic volume. 2.2 Volume Count Study (Straight Road Stretch)
To determine the number, movement and classification of roadway vehicles at a given location. The number of observers needed to count the vehicles depends upon the number of lanes in the highway on which the count is to be taken and the type of information desired. The indications in table can be used as rough guides. It is perhaps more desirable to record traffic in each of travel separately and past separate observer for each direction enumerators should be literate persons with preferably middle or matriculation level for the purpose.
This survey has been conducted at Urvasi, Kancharpalem and Gnanapuram of T-Intersections.
2.3 Volume Count Study (An Intersection)
To determine the number, movement and classification of roadway vehicles at an intersection. Traffic volume studies are conducted to determine the number of movements and classification of roadway vehicles at a given location. These data can help identifying critical flow time periods, determine the influence of large vehicles or pedestrians on vehicular traffic flow or document traffic volume trends. The length of the sampling period depends on the type of count being taken and the intended use of the data recorded. For manual count, 15min interval could be used to obtain the traffic volume data. This survey has been conducted at Urvasi, Kancharpalem and Gnanapuram of T-Intersections. 2.4 Gap Acceptance Study Pedestrians preparing to cross the roadway must access the gaps in conflicting traffic determine whether sufficient length is available for crossing and decide to cross the road. Following experiments presents a method for collecting field data to identify the minimum usable gap. As if any traffic engineering analysis recognition and definition of the difference between the standard values and the observed values, the observed values increase the accuracy. This survey has been conducted at Urvasi, Kancharpalem and Gnanapuram of T-Intersections. 2.5 Gap Acceptance Capacity Model The theory of gap-acceptance is the major concept for unsignalized intersection analysis. This method is based on critical gap acceptance and follow up times of vehicles from the minor road. The modified Tanner’s formula was found to be the most suitable model. Tanner proposed a theoretical model to relate the various parameters connected with the delay problem in dealing with an Intersection of a Major and Minor road and for finding capacity at unsignalized intersections and the expression is as follows: 퐶푝= 푞푀(1−휆푡푝)푒−휆(푡푐−푡푝) 1−푒−휆푡푓 Where, λ= qM/3600 (veh/s) tp=minimum headway in the major traffic stream tc= critical gap qM= number of major stream headways tf = follow-up gap respectively

1. Conflict technique is a simple method for calculating capacity of unsignalized intersections.
2. The modified Tanner’s formula was found to be the most suitable model.
3. The input data like Volume, Flow, and Capacity of each type of vehicle can be measured from the field where as for gap acceptance models the input parameters i.e., Critical gap and Follow up time (tc, tf) are measured.
4. By Comparing all the 3 T-intersections are:
The study area Kancharpalem has shown the mixed traffic conditions.
The study area Gnanapuram has shown the Major Stream.
The study area Urvasi has shown the Major Stream.
5. The signal should be provide at Kancharpalem and Gnanapuram Junctions.
