摘要 隨著城市化進(jìn)程的加快及機動車輛人均擁有率的增加，城市交通問題己成為影響社會進(jìn)步的熱點及難點問題。而城市主干道作為城市交通網(wǎng)絡(luò)中車輛通行的大動脈，承擔(dān)著車輛流通的重?fù)?dān)。因此，在解決城市交通阻塞問題中，重中之重的是提高干線上車輛的通行能力，減少車輛的阻塞次數(shù)?，F(xiàn)代城市交叉口信號控制理論研究證明：交叉口信號間的協(xié)調(diào)優(yōu)化，使得交通流在交叉口處遇到綠燈信號而不停車等待，形成道路雙向交通流的“綠波帶”，將極大地改善交通擁堵現(xiàn)象。由于地理資源和資金的限制，尚難以通過道路的大量投資建設(shè)，來滿足城市交通發(fā)展的需要。因此，提高現(xiàn)有道路的通行能力成為解決城市道路設(shè)施負(fù)擔(dān)過重的突破點。
本文針對現(xiàn)代交通中干線協(xié)調(diào)控制的問題，對城市主干道雙向綠波帶控制優(yōu)化進(jìn)行了研究，主要工作如下：
（1）本文針對城市干道協(xié)調(diào)理論與方法，對國內(nèi)外的研究現(xiàn)狀做了一個回顧，然后討論了城市交通信號控制的基本理論。就如何根據(jù)各交叉口幾何特性、交通流特征等影響因素，合理進(jìn)行交叉口信號燈配時的問題進(jìn)行了探討，并在此基礎(chǔ)上，研究了干線交叉口交通信號協(xié)調(diào)控制理論。
（2）給出干線信號聯(lián)動控制系統(tǒng)的設(shè)計思路和流程,再依據(jù)設(shè)計思路,以鎮(zhèn)江市學(xué)府路為例,對采集到的數(shù)據(jù)進(jìn)行分析處理,得出設(shè)計方案。

Abstract With the acceleration of the process of urbanization and the increasing ownership of vehicles, the issue of transportation has become a thorny and difficult problem in urban. As the city traffic artery of traffic network, urban trunk road take the great role in the traffic flow. To solve the urban traffic problem, the most importance is to improve the capacity of the trunk road, to reduce the number of vehicles blocking. The modern urban intersection signal control theory proves that the coordination and optimization during the intersection signals makes the traffic flow pass through the intersection in the green light without stopping , forming the "green wave band" of two-way road traffic flow,which will greatly improve the traffic congestion. Owing to the limit of geography resources and the funds, to satisfy the needs of municipal transportation is hard to implement just by big investing in traffic construction still. Therefore, improving the capacity of the existing traffic line become the breakthrough point to solve overburdened of the urban road facility.
On the basis of analyzing the problems of traffic signal coordination control of trunk road, the thesis makes a study on optimal control of dynamic Bidirectional Green-Wave. The research mainly includes several parts as follows:
（1）Firstly,aiming at urban arterial traffic signal coordination control theory and methods,I present a review of its studies at home and abroad.Then,I discussed the basic theory of urban traffic signal control.This paper probes into the problem of how to timing the signal rationally at the intersection according to the influencing factors such as the geometrical features and characteristics of the traffic flow of each intersection,and based on this,this paper researches the theory of arterial traffic signal coordination control at the intersection of the trunk road.
（2）The paper presents the design thinking and process of the arterial coordination control system.Then according to the design thinking and process,XueFu Road of ZhenJiang City is taken for example.The survey data are analyzed and the scheme is acquired.
Key words：intersection, signal control,artery road control system,green wave
