摘   要
     城市道路交通擁擠是當今世界普遍關注的問題，它所帶來的嚴重危害日益影響到人們的日常生活和社會經濟的發展。交叉路口作為城市交通的主要集散點，是產生交通擁擠的重要環節，對其交通流進行合理分析和控制，是緩解交通擁擠的重要手段和途徑，也是研究城市交通問題的一個關鍵切入點。城市干線道路作為城市道路網中的重要組成部分，它的通暢與否直接影響整個城域交通網絡能否平穩、安全的運行。因此本文以此為出發點，開展了對城市道路交通信號控制的研究，重點研究了城市相鄰交叉口的協調優化控制的方法。
    本文針對目前城市交通問題的現狀，首先分析和討論了交通信號控制的基本理論及單個交叉口的信號配時方案；其次，研究了干線相鄰交叉口交通信號聯動控制的基本理論及配時方案，重點研究了城市相鄰交叉口交通信號的協調優化控制，分析了現有的單個交叉口的信號控制的交通現狀，對其不足，給出了單個交叉口的最佳渠化方案，并以使車輛的總延誤減小和提高系統的交通效益為目標，通過相鄰信號協調控制的方法，建立了以相位差為優化控制變量的動態協調控制系統。并給出了相鄰交叉口協調控制系統的帶速。最后，對原有的單個交叉口的信號控制與渠化后的方案進行了對比分析，證明了本文所提方法的有效性及可行性。
    本文采用英國韋伯斯特方法對單個交叉口進行渠化，又采用了數解法計算協調控制系統的信號時差，求解出了相鄰交叉口的通過帶速，形成了全球通大橋相鄰交叉口間的綠波帶。雖然只是實現了小范圍的綠波控制，但文中方案的優勢較原方案相比還是比較明顯的。因此，本文提出的方法還是具有解決城市道路協調控制及城市交通擁擠問題的潛力的。

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.
