摘要
通过对黄骅市迎宾大街—新海路交叉口高峰时段交通调查,发现信号交叉口发生拥堵的各种问题,提出了以交叉口渠化设计和信号周期配时设计为主要研究对象的优化设计方案,运用VISSIM软件仿真对延误和排队时间进行分析,对信号交叉口改善前和改善后的延误水平和服务水平进行分析和对比研究,证明信号交叉口优化设计方案的合理性。
By investigating the peak traffic at Yingbin Street-Xinhai Road intersection in Huanghua City,this paper finds out various problems of congestion at signalized intersection,and puts forward an optimal design scheme with intersection channelization design and signal cycle timing design as the main research object.The delay and queuing time are analyzed by VISSIM software simulation,and the delay before and after improvement of signalized intersection is analyzed.The error level and service level are analyzed and compared to prove the rationality of the optimal design of signalized intersections.
