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.
