Simulation of rotary intersection at K. R. hospital junction

Abstract

In today’s scenario, cities are facing a lot of traffic problems due to increase in rate of vehicles. This has resulted in many adverse effects like pollution, delay in reaching destination, accidents and traffic congestion. Increased rate of vehicles requires more space for movement. The rotary intersection is the most vital component of urban roadway network. Hence, there is a need for capacity evaluation of rotary intersection for easy movement of vehicles which reduces accidents and improves the traffic management. The present research work is focused on calculation of PCU values, peak hour PCU capacity evaluation and redesign of rotary intersection as per IRC: 65 – 1976 and simulation of rotary intersection using vissim software. After simulation and redesign of the rotary intersection, the capacity of the rotary circle was increased from 3111 to 4081 PCU. Further, the vehicles should follow the lane traffic rules.
