基于VISSIM仿真的交叉口信号配时优化方案
Optimization scheme of intersection signal timing based on VISSIM simulation:A case study of Jiangsu Avenue and Jiangchong Road intersection in Lhasa
摘要
Abstract
As a key node in the urban road network,intersections experience traffic congestion in the context of accelerated urbanization.This study takes the intersection of Jiangsu Avenue and Jiangchong Road in Lhasa as the research object.After obtaining basic data through field surveys,a traffic flow model is constructed using the VISSIM simulation platform,and phase timing optimization is implemented in combination with the Webster signal cycle algorithm.The results show that the optimization plan reduced the core indicators of queue length,maximum queue length,average vehicle delay,and stop delay by 23%,18%,19%,and 25%,respectively.This effectively relieved the congestion pressure at the intersection and significantly improved the traffic operation efficiency of the node.关键词
