基于VISSIM微观仿真的错位交叉口改善策略

Strategies of Staggered Intersection based on Microscopic Simulation with VISSIM

错位交叉口是一种特殊的平面交叉口,由于其自身特性,严重影响了交叉口的通行能力和行车安全。通过对错位交叉口的研究提出相应的改善策略,对提高交叉口的通行能力和行车安全具有非常重要的意义。利用微观交通仿真软件VISSIM的模拟和预测功能,对淄博市人民路与西六路错位交叉口进行仿真分析,结合组群城市中心城区的实际情况,提出多个微观改善策略,具有一定的现实意义。

As a result of the historical reason, there are some irregular intersections such as staggered intersection in many the old city zone. Staggered intersection is a special kind of plane intersection, which affects seriously the traffic capacity and safety of the characteristic of the intersection. It is very meaningful to improve the traffic capacity and traffic safety by study the staggered intersection and make improvement strategy. The traffic microscopic simulation software VISSIM contains the function of simulation and predicting. The staggered intersection of Ren Min road and Xi Liu road of Zibo city to be simulated and analyzed by VISSIM, and many microscopic improving strategies were proposed by combining to actual situation of central city zone of Zibo city, and these improving strategies were simulated and analyzed by VISSIM, and the suitable scheme was selected.
