Abstract
The traffic of an urban area increases rapidly due to the growth in population and vehicle ownership. With the advancement in transportation and urbanisation, traffic congestion has become the main socio-economic problem in urban as well as rural areas in developing countries. Careful and balanced management is required for this increased traffic problems. The urban road of India generally carries the heterogeneous traffic which is the combination of various types of vehicles like cars, buses, motor cycles, trucks, auto rickshaws, carts, etc. These all vehicles have different size, speed, load carrying capacities or passenger capacities, etc. which affect the traffic flow. The variation in carriageway width is common especially in developing countries. Due to change in carriageway width, the traffic stream speed also encounters more congestion level along the length of link. In case of homogeneous traffic the characteristics of traffic does not change abruptly, as the traffic mainly consisting of same type of vehicles. While in case of heterogeneous traffic, there is a combination of different type of vehicles which have a remarkable variation in the traffic stream characteristics. Traffic congestion is managed conventionally by signalisation, widening the roads, interchanges and intersections. Intersections provided sometimes prove the best but growth of population leading to continuous increase in traffic brings with it a deadlock condition. Intersections are the junction (at same level) of two or more roads either meeting or crossing. This study deals with cross intersection provided at Pakwan cross road, connecting Sarkhej-Gandhinagar Highway and Bodakdev-Sindhubhavan Road. The study works for three main parameters: Capacity of Intersection, Heterogeneous traffic flow simulation using VISSIM and suitable measures to be taken for reducing traffic congestion and reconfigure the intersection. The main objective is to survey the study area and to prepare a model of the same. By comparison of the actual data obtained by survey and the data obtained from model, find out the actual reason for the traffic congestion and to give necessary suggestions for solving the problem.
