Study the Effect of Traffic Heterogeneity in a Coordinated Corridor using Simulation
Ponpriya M,  Dr.Gunasekaran K
Urban roads are experiencing a significant period of congestion and delay due to traffic signals. Traffic signal timing optimization and coordination are an easy and very cost-effective way to improve the flow of traffic along the corridor. By altering and retiming existing traffic signals to the traffic flow variations, the efficiency of each intersection will improve. For the study, the Chennai Airport to Kathipara intersections was taken. The stretch has seven signalized intersections. The morning peak flow was during 8:00am and 9:00am. Signal timings were optimized using Macro Simulation software. The vehicular flow in PCU values and link attributes are given as input and the signal timings were optimized and coordinated with offset timings. The traffic flow in the network was simulated with the aid of microsimulation software to understand the vehicle to vehicle interaction and flow characteristics at the micro level. The study findings are reported in this paper.
Keywords- Coordination, Offset timings, Optimization, Signal timings.
