【摘要】:随着城市的发展,交通需求和城市路网密度随之增长,道路交通对于城市的发展和人们的出行变得愈发重要。交叉口作为城市路网的基本组成单元,是道路交通拥堵的常发区域,如何从整个系统的战略角度出发,针对交叉口之间的关联性进行有效的交通协调控制,已经成为城市交通控制的新需求。本文针对现有交通控制方法的不足,从我国城市路网结构入手,通过分析道路交通流运行状态,对干线排队车辆消散、干线协调优化控制、路网协调优化控制、远程交通信号控制系统的构建等方面进行了相关研究,主要研究成果概括如下: 1.对道路交通流运行状态进行分析,根据道路交通流特性,建立了两种车流情况下的排队车辆消散模型:非饱和情况下的排队车辆消散模型与过饱和情况下的排队车辆消散模型。在现有的绿波协调控制方法基础上,将排队车辆消散模型引入干线绿波控制,建立了基于排队车辆消散的干线绿波控制方法,给出了完整的公共周期时长、绿信比、相位差的计算方法。 2.分析我国城市路网结构特征,对复杂干线路网进行分类:普通交叉干线路网和“井”字形干线路网。在前述基于排队车辆消散的干线绿波控制方法的基础上,建立路网协调控制优化目标,给出了基于排队车辆消散的复杂干线路网绿波协调控制方法。 3.针对如何有效地将先进的交通信号控制技术应用到实际的交通信号控制系统中,真正实现最佳交通信号控制方案的计算、选取、以及应用到路口的问题,构建了远程交通信号控制系统。对信号控制系统模块、服务器处理方式、控制方案过渡等方面进行了研究。通过交通仿真分析与系统在温州市龙湾区的实际运行,对本文协调控制方法和远程交通信号控制系统的稳定性和有效性进行验证,综合有效的验证了本文协调控制方法的科学和理性。
[Abstract]:With the development of the city, the traffic demand and the density of the urban road network increase, and the road traffic becomes more and more important for the development of the city and people's travel. As a basic component of urban road network, intersection is a common area of traffic congestion. From the strategic point of view of the whole system, how to carry out effective traffic coordination control in view of the intersections' correlation. It has become a new demand for urban traffic control. In view of the deficiency of the existing traffic control methods, starting with the structure of the urban road network in China, this paper analyzes the running state of the traffic flow on the main lines, such as the vehicle dissipation in line, the coordinated optimal control of the trunk lines, and the coordinated optimal control of the road network. The construction of remote traffic signal control system is studied. The main research results are summarized as follows: 1. According to the characteristics of road traffic flow, two queuing vehicle dissipation models are established, namely, the queuing vehicle dissipation model under unsaturated condition and the queuing vehicle dissipation model under supersaturated condition. Based on the existing coordinated green wave control methods, the queuing vehicle dissipation model is introduced into the main line green wave control, and the main line green wave control method based on the queuing vehicle dissipation is established, and the complete public cycle time and the green signal ratio are given. Calculation method of phase difference. 2. This paper analyzes the structural characteristics of urban road network in China and classifies the complex trunk road network: the common cross trunk network and the "well" zigzag trunk network. On the basis of the above mentioned green wave control method for trunk line based on queuing vehicle dissipation, the optimization goal of coordinated control of road network is established, and the coordinated control method of green wave in complex trunk road network based on queueing vehicle dissipation is presented. In order to solve the problem of how to effectively apply the advanced traffic signal control technology to the actual traffic signal control system, to realize the calculation, selection and application of the optimal traffic signal control scheme, The remote traffic signal control system is constructed. The signal control system module, server processing mode and control scheme transition are studied. Through the traffic simulation analysis and the actual operation of the system in Longwan District of Wenzhou City, this paper verifies the stability and effectiveness of the coordinated control method and the remote traffic signal control system. It verifies the science and rationality of the coordinated control method in this paper synthetically and effectively.
