【摘要】：隨著城市的發(fā)展,交通需求和城市路網(wǎng)密度隨之增長,道路交通對于城市的發(fā)展和人們的出行變得愈發(fā)重要。交叉口作為城市路網(wǎng)的基本組成單元,是道路交通擁堵的常發(fā)區(qū)域,如何從整個系統(tǒng)的戰(zhàn)略角度出發(fā),針對交叉口之間的關(guān)聯(lián)性進行有效的交通協(xié)調(diào)控制,已經(jīng)成為城市交通控制的新需求。本文針對現(xiàn)有交通控制方法的不足,從我國城市路網(wǎng)結(jié)構(gòu)入手,通過分析道路交通流運行狀態(tài),對干線排隊車輛消散、干線協(xié)調(diào)優(yōu)化控制、路網(wǎng)協(xié)調(diào)優(yōu)化控制、遠程交通信號控制系統(tǒng)的構(gòu)建等方面進行了相關(guān)研究,主要研究成果概括如下： 1.對道路交通流運行狀態(tài)進行分析,根據(jù)道路交通流特性,建立了兩種車流情況下的排隊車輛消散模型：非飽和情況下的排隊車輛消散模型與過飽和情況下的排隊車輛消散模型。在現(xiàn)有的綠波協(xié)調(diào)控制方法基礎(chǔ)上,將排隊車輛消散模型引入干線綠波控制,建立了基于排隊車輛消散的干線綠波控制方法,給出了完整的公共周期時長、綠信比、相位差的計算方法。 2.分析我國城市路網(wǎng)結(jié)構(gòu)特征,對復(fù)雜干線路網(wǎng)進行分類：普通交叉干線路網(wǎng)和“井”字形干線路網(wǎng)。在前述基于排隊車輛消散的干線綠波控制方法的基礎(chǔ)上,建立路網(wǎng)協(xié)調(diào)控制優(yōu)化目標(biāo),給出了基于排隊車輛消散的復(fù)雜干線路網(wǎng)綠波協(xié)調(diào)控制方法。 3.針對如何有效地將先進的交通信號控制技術(shù)應(yīng)用到實際的交通信號控制系統(tǒng)中,真正實現(xiàn)最佳交通信號控制方案的計算、選取、以及應(yīng)用到路口的問題,構(gòu)建了遠程交通信號控制系統(tǒng)。對信號控制系統(tǒng)模塊、服務(wù)器處理方式、控制方案過渡等方面進行了研究。通過交通仿真分析與系統(tǒng)在溫州市龍灣區(qū)的實際運行,對本文協(xié)調(diào)控制方法和遠程交通信號控制系統(tǒng)的穩(wěn)定性和有效性進行驗證,綜合有效的驗證了本文協(xié)調(diào)控制方法的科學(xué)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.
