太湖大道干道信号协调控制研究
摘 要
21 世纪以来,随着社会经济的高速发展,人民生活水平不断提高,城市人口也不断增多,车辆保有量成线性增加,城市交通压力也日益加重,而城市交通流主要汇集地是干道路线,因此最常见的堵塞通常发生在一些干线道路,尤其是干线上的交叉口。近年来,路网设计被不断提出,并高速发展,在干线上设计设置信号绿波带能大大改善道路的通行状况。本文就以苏州市太湖大道干线为研究对象,通过对干线上三个交叉口的调查及分析,计算出合理的信号配时,根据计算结果建立合适的模型,再利用VISSIM 交通仿真软件将关键参数进行数据对比,从而确定最优方案,以达到改善太湖大道干线的交通拥堵问题的目的。

Research on the design of the signal coordination
control of the main road of the Taihu road
Abst ract
Since the 21st century, with the rapid development of the social economy, the people#39;s living standards have been continuously improved, the urban population has also increased, the number of vehicles has increased linearly, and urban traffic pressures have increased. The main collection of urban traffic is dry roads. The most common blockages usually occur on some main roads, especially at intersections on the main line. In recent years, road network design has been continuously proposed and developed at a high speed. Designing a signal green wave band on the trunk line can greatly improve the road traffic conditions. This paper takes the Taihu Avenue trunk line in Suzhou as the research object. Through the investigation and analysis of the three intersections on the trunk line, the reasonable signal timing is calculated, and the appropriate model is established according to the calculation result. Then the key parameters are calculated by using VISSIM traffic simulation software. Data comparison is carried out to determine the optimal solution to achieve the purpose of improving the traffic congestion problem of the Taihu Avenue trunk line.
Key words green wave band; intersection;signal timing;simulation
