【摘要】：随着我国机动车保有量的急剧增加,城市交通问题日益突出。城市主干道作为城市交通道路体系中的重要组成部分,其通畅与否决定了整个城市交通网络系统能否平稳、安全、高效地运行。而交叉口交通情况复杂,交通事故多发,是解决城市道路交通问题的瓶颈。因此,为减少车辆延误,使交通流高效通畅运行,需要在主干路交叉口进行交通信号的协调控制。本文以缓解城市交通压力,提高城市道路实际通行能力为出发点,对城市主干路交通协调控制管理进行研究把城市主干路上相邻交叉口作为一个统一联动的系统来分析研究交通协调管理与控制的优化方法,并对其交通流情况进行仿真。首先,本文对国内外城市信号控制发展情况进行阐述;然后从人、车、路的交通特性和交通流特性两方面对主干路交通特性进行分析;接着城市干线系统信号协调控制的基本内容、主要算法和优化方法进行分析,最后进行线控系统仿真研究,并对幸福街与兴济桥西路、兴济桥东路交叉口进行实例分析,采用VISSIM仿真软件对其数据及结果进行仿真,从而对整个干道信号协调控制系统的交通状况进行全面的了解。
[Abstract]:With the rapid increase in the number of motor vehicles in China, urban traffic problems are increasingly prominent. As an important part of the urban traffic road system, the urban main road is smooth or not, which determines whether the whole urban traffic network system can run smoothly, safely and efficiently. The complex traffic situation and frequent traffic accidents at intersections are the bottlenecks to solve urban road traffic problems. Therefore, in order to reduce vehicle delay and make traffic flow efficient and smooth, it is necessary to carry out traffic signal coordination control at main road intersections. This paper aims at alleviating the pressure of urban traffic and improving the actual capacity of urban roads. The traffic coordination and control management of urban trunk roads is studied. The adjacent intersections on urban trunk roads are regarded as a unified linkage system to analyze and study the optimization method of traffic coordination management and control, and the traffic flow is simulated. Firstly, this paper expounds the development of urban signal control at home and abroad, and then analyzes the traffic characteristics of trunk roads from the aspects of traffic characteristics of people, vehicles and roads, and traffic flow characteristics. Secondly, the basic contents, main algorithms and optimization methods of signal coordination control in urban trunk line system are analyzed. Finally, the simulation study of wire control system is carried out, and an example is given to the intersection of Xingji Bridge West Road and Xingji Bridge East Road. The data and results of the system are simulated by VISSIM software, so that the traffic condition of the whole signal coordination control system of the trunk road can be fully understood.
