全感应控制方法是一种适合交叉口交通量随机变化比较大的交通信号控制方法。为了验证该方法的有效性,文章以单个交叉口为研究对象,运用Vissim交通仿真软件进行建模,并分析比较在不同时段下,实施全感应控制与定时控制方式后的各项交通信号控制性能指标。仿真结果表明,与定时控制相比,全感应控制在不同时段下的各项交通信号控制性能指标均有所改善:高峰时段,全感应控制的平均行程时间改善了4.26%,平均延误时间改善了15.6%,平均停车次数改善了1.3%,平均排队长度改善了17.4%。
The full induction control is a traffic signal control method which is suitable for intersections with large changing in traffic flow.In order to verify the validity of the method,this paper takes a single intersection as the research object,using the Vissim traffic simulation software to analyze the traffic signal control indexex of the full induction control method and the fixed control method in different stages.The results show that,compared with the fixed control method,the traffic signal control indexes of full induction control method are improved obviously.Taking the high stage as an example,the improvement of the average travel time is 4.26%,the improvement of the average delay time is 15.6%,the improvement of the average number of stops is 1.3%,and the improvement of the average queue length is 17.4%.
