摘　　要：道路交叉口的通行能力是道路服务水平的重要组成部分,交叉口信号配时的优化是改善通行能力、提高车辆运行效率的重要手段。以某道路交叉口为例,进行实地调查并收集相应数据,运用Vissim软件对其进行模拟仿真,并输出最大排队长度、停车延误和人均延误等参数。根据相关标准对该道路交叉口运行状况进行评价,通过ARRB信号周期模型对该道路交叉口的绿灯时长进行优化,运用Vissim软件进行模拟并输出相关参数,与优化前各参数进行对比。结果表明:在优化后的信号配时方案下,平均最大排队长度下降29.83%,平均停车延误下降40.17%,平均人均延误下降34.49%,该道路交叉口的通行效率显著提升。Traffic capacity of road intersection is an important part of road service level,and the optimization of signal timing at intersection is an important means to improve traffic capacity and improve vehicle operation efficiency.Taking a road intersection as an example,field survey was conducted and corresponding data was collected.It was simulated using Vissim,and outputting parameters such as maximum queue length,parking delay and per capita delay.The operating condition of the road intersection was evaluated according to the relevant standards,the green light time of the road intersection was optimized through the ARRB signal cycle model,and Vissim was used to simulate and output relevant parameters,comparing with the parameters before optimization.The results showed that under the optimized signal timing scheme,the average maximum queuing length decreased by 29.83%,the average parking delay decreased by 40.17%,the average per capita delay decreased by 34.49%,and the traffic efficiency of the road intersection was significantly improved.
