摘   要
     城市道路交通拥挤是当今世界普遍关注的问题，它所带来的严重危害日益影响到人们的日常生活和社会经济的发展。交叉路口作为城市交通的主要集散点，是产生交通拥挤的重要环节，对其交通流进行合理分析和控制，是缓解交通拥挤的重要手段和途径，也是研究城市交通问题的一个关键切入点。城市干线道路作为城市道路网中的重要组成部分，它的通畅与否直接影响整个城域交通网络能否平稳、安全的运行。因此本文以此为出发点，开展了对城市道路交通信号控制的研究，重点研究了城市相邻交叉口的协调优化控制的方法。
    本文针对目前城市交通问题的现状，首先分析和讨论了交通信号控制的基本理论及单个交叉口的信号配时方案；其次，研究了干线相邻交叉口交通信号联动控制的基本理论及配时方案，重点研究了城市相邻交叉口交通信号的协调优化控制，分析了现有的单个交叉口的信号控制的交通现状，对其不足，给出了单个交叉口的最佳渠化方案，并以使车辆的总延误减小和提高系统的交通效益为目标，通过相邻信号协调控制的方法，建立了以相位差为优化控制变量的动态协调控制系统。并给出了相邻交叉口协调控制系统的带速。最后，对原有的单个交叉口的信号控制与渠化后的方案进行了对比分析，证明了本文所提方法的有效性及可行性。
    本文采用英国韦伯斯特方法对单个交叉口进行渠化，又采用了数解法计算协调控制系统的信号时差，求解出了相邻交叉口的通过带速，形成了全球通大桥相邻交叉口间的绿波带。虽然只是实现了小范围的绿波控制，但文中方案的优势较原方案相比还是比较明显的。因此，本文提出的方法还是具有解决城市道路协调控制及城市交通拥挤问题的潜力的。

ABSTRACT
       Urban road traffic congestion is now the world universal matter of concern, it brings the severely impair affects day by day people's daily life and the social economy development. The four corners took the municipal transportation the main nodal point, produces the traffic congestion important link, carries on the reasonable analysis and the control to its transportation class, is alleviates the traffic congestion important method and the way, also is studies the municipal transportation question an essential breakthrough point. The city skeleton line path takes in the city system the important constituent, its unobstructed or not direct influence entire city territory transportation network whether steady, safe movement.Therefore this article take this as a starting point, has developed to the urban road traffic signal control research, has with emphasis studied the city neighboring road intersection coordinated optimization control method.
This article in view of at present municipal transportation question present situation, first analyzed and discussed the traffic signal control elementary theory and the single road intersection signal timing plan; next, has studied the skeleton line neighboring road intersection traffic signal linkage control elementary theory and the timing plan, has with emphasis studied the city neighboring road intersection traffic signal coordinated optimization control, has analyzed the existing single road intersection signal control transportation present situation, to its insufficiency, has given the single road intersection best channelization plan, and take makes the vehicles the total delay to reduce and to enhance the system the transportation benefit as the goal, through neighboring signal coordination control method, has established take the phase difference as the optimized control variable tendency coordination control system.And has given the neighboring road intersection coordination control system belt fast.Finally, has carried on the contrast analysis after the original single road intersection signal control and the channelization plan, had proven this article proposes the method the validity and the feasibility.
   This article uses the English webster method to carry on the channelization to the single road intersection, also has used the analytic method computation coordination control system signal time difference, solved the neighboring road intersection through the belt fast, formed the whole world to pass the green wave band between the bridge neighboring road intersection.Although has only realized the small scope green wave control, but in the article the plan superiority original plan compares quite obviously. Therefore, this article proposed the method has solves the urban road coordination control and the municipal transportation crowded question potential.
