摘要
分析了城市道路交叉口的平均延误时间、道路通行能力和信号配时的数学模型和计算方法。在对宝鸡市的22个主要信控交叉口进行了大量的交通调研的基础上,选取了有代表性的太白路、公园路上多个交叉口作为协调控制交叉口,阐述了交叉口信号协调控制系统的设计方法。最后通过公式计算和Synchro系统仿真的两种方法,对线控前后的系统进行了对比,结果表明宝鸡市受控干道交叉口的延误和通行能力得到了明显的改善。
In this paper, the mathematic model and calculation method of intersection average delay, capability of road and intersection signal timing are analyzed. Based on the research and analysis of 22 main intersections in Baoji City, this paper selects several typical intersections of Taibai Road and Gongyuan Road as signal coordination control intersections and then introduces the design method of the signal coordination control system. Finally, the paper compares the signal coordination control systems both before and after the application of the linear control system with the help of formula calculation and Synchro software system. The results show that the intersection delay and capability of road are significantly improved.
