Optimization of Green Wave Signal Timing for Urban Intersection Based on VISSIM——A Case Study of Shenzhen University Section of Baishi-Road

Nearby Shenzhen Univeristy,Baishi Road holds a large segment where traffic is steady at peak hours. The distance between the intersection of Yue Hai Men Cunand Gui Miao Cun Kouis 1. 4km,and the signal timing plans at the two intersections are similar so that its traffic signal control can be researched by using the Green Wave. The paper,uses manual calculation method to collect data acquisition and do signal timing phase of the two the intersections,then analyzes the data and implements three kinds of optimized timing plans of the Green Wave. The simulation model is established by VISSIM. Simulation results show that by using the three kinds of optimization,the total of two-way traffic delays,parking time and number of stops decrease 36. 5%,36. 8% and 40. 6%,respectively,it effectively improve the prevailing rates and service levels.
