基于Synchro-VISSIM系统的畸形交叉口改善及评价方法

Improvement and Evaluation Method for Deformity Intersection Based on Synchro-VISSIM System

针对现行畸形交叉口的改善与评价理论体系中存在的若干问题,提出了一种基于Synchro-VISSIM系统的改善与评价方法。首先,对Synchro中关于信号配时优化的模型及VISSIM中关于驾驶员行为的模型进行介绍。其次,提出了基于两种软件分析结果的,适用性较好的新型畸形交叉口改善及评价方法。最后,以秦皇岛市海浪花交叉口为例进行了分析,并运用该方法对此进行改善与评价,得到了服务水平由E级跃升到C级的结论。该方法的提出完善了我国现阶段的畸形交叉口改善与评价理论体系,而且具有良好的可操作性和实用性。

In order to solve the problems of improvement and evaluation theoretical system of deformity inter- section, an improvement and evaluation method was proposed which is based on the Synchro-VISSIM system. Signal timing optimization model in Synchro and driver behavior model in VISSIM were introduced. An im- provement and evaluation method was proposed which is good at applying for deformity intersection based on the results obtained from Synchro and VISSIM. Finally, Hailanghua intersection of Qinhuagndao （deformity intersection） was taken as the example to improve and evaluate by this method, the service level of this inter- section had been raised from E to C. This method perfects the improvement and evaluation theoretical system of China at this stage, and has good maneuverability and practicality.
