基于Synchro的信号交叉口优化仿真研究

摘要

通过对西安市某信号控制交叉口进行大量实际观测，分析了该交叉口存在的问题并提出解决方案，运用Synchro仿真系统中信号配时优化模型、用于延误计算的百分比延误模型和服务水平模型，对解决方案进行了优化仿真分析，交叉口各项评价指标均得到明显改善，验证了改善方案的可行性。%Through the actual observation of a signalized intersection in Xi'an city,on this basis,the papers analyzes the problem of the signalized intersection and propose solving scheme.Using the time optimization model,PDM (percentile delay method)and LOS(level of service)model in synchro software system,the papers analyzes the optimization simulation results of solving scheme,all kinds of evaluation index have been improved,the feasibility of the solving scheme has been verified.
