山地城市商圈环道信号协同控制方法
Signal Collaborative Control Method for Ring Roads in Business District of Mountainous City
摘要
Abstract
The ring roads in mountainous city business districts are prone to congestion due to numerous intersec-tions and fluctuating traffic flows.To address this,a cooperative signal control method for managing ring roads entrances and exits is proposed.Road and traffic characteristics were extracted using high-altitude video,check-point data,and Internet-based datasets.The control objectives include maximizing vehicle throughput,minimiz-ing entrance queue lengths,and reducing downstream congestion at exit intersections.The optimization model is constrained by signal control parameters,queue lengths,and overall ring roads density.The standard NSGA-Ⅱalgorithm was improved in operator design and population size configuration.A MATLAB-VISSIM simulation platform was developed for joint simulation.A case study of the Guanyinqiao business district ring roads in Chongqing was conducted.Results show that,compared to the original scheme,the optimized strategy increases ring roads capacity by 8.9%during peak hours,reduces entrance lane queue length by 31.7%,and decreases exit lane queue length by 15.0%.These findings validate the effectiveness of the proposed multi-objective optimiza-tion and cooperative signal control method.By enhancing coordination among multiple intersections,this ap-proach provides valuable guidance for alleviating regional traffic congestion during peak hours.关键词
