摘要
基于VISSIM建立交叉口交通仿真模型,选取排队长度、延误时间和服务水平三项指标对优化前后设计方案进行交通仿真分析,从而筛选出更合理的交叉口设计方案,为交叉口优化设计提供明确的方向。
Based on VISSIM,establishing the intersection traffic simulation model and selecting three indicators of queue length,delay time and service level,the traffic simulation analysis is optimized before and after the design scheme,so as to screen out a more reasonable intersection design scheme,then provide clear directions for intersection optimization design.
