Comparative Analysis of Synchro Optimization Plans for Arterial Signal Coordination Based on Vissim Simulation
摘要
Abstract
In order to determine the optimal signal timing plan in Synchro for signal coordination on the arterial road,three simulation platforms were established by using VISSIM model based on the criteria of minimum delay,minimum stops,and minimum PI,respectively.A comparative analysis was conducted between the optimization plans by using the evaluation indexes of vehicle delay,vehicle travel time,queue length,and vehicle stops.A case study was carried out on Siwei Road in the East Section of Beijing Capital International Airport.The results indicate that the timing plan optimized based on the minimum delay performs best when all the four indexes are jointly considered.Consequently,it is recommended to adopt the optimization plan based on minimum delay instead of the default minimum PI when Synchro is used for arterial signal coordination.Further,the optimization timing plan based on the minimum PI performs significantly better than that based on the minimum stops on all indexes except vehicle stops.关键词
