考虑汇入汇出车流影响干线协调相位差模型构建与应用

为解决城市道路拥堵问题，在干线协调的基础上，充分考虑上游交叉口左右转向车流。分析这些车辆运行至下游交叉口排队情况，给出一种动态相位差模型的计算。在VISSIM仿真基础上结合MATLAB进行二次开发，随着上游交叉口左右转向交通量的不断变化，模型会及时调整周期、绿信比等，也会结合排队情况给出新的相位差，再通过VISSIM中的检测器，检测车辆延误、停车次数等。结合大连市实际数据验证，结果表明：考虑汇入车流对城市道路干线协调相位差影响是具有重要意义，干线车流总延误较原配时方案减少33.3%，停车次数减少65.6%。

Construction of the Offset Model Base on the Influence of Remittance Traffic Flow on Arterial Coordination and Application

In order to solve the problem of road congestion in the city, based on the coordination give full consideration to the upstream intersection of left and right turn traffic. Analyzes the queuing conditions of these vehicles running to the downstream intersection and gives a calculation of the phase difference model. Based on VISSIM simulation combined with MATLAB to develop two times, with the constant change of the traffic in the upper reaches of the upper intersection, the model will adjust the cycle and the green signal ratio and will give new phase difference based on queuing. It was detected that he vehicle delay, the number of parking and so on through the detector in the VISSIM. Based on Dalian actual data validation the results show that it is of great significance to consider the influence of the remittance flow on the coordinated phase difference between the urban road trunk lines. The total traffic delay line is the original scheme is reduced by 33.3%, 65.6% reduction in the number of parking.
