基于相邻相位合作博弈的单信号交叉口实时滚动优化建模和仿真

Modelling and Simulation of Single Signal Intersection Real-time Rolling Optimization Based on Adjacent Phases Cooperation Game

通过对切换相位时各相位进口道的平均停车时间公式的推导,证明了执行绿灯的相位与执行红灯的相位存在对绿灯资源的博弈。以此为基础,建立了以执行绿灯的相位和下一相位为联盟的合作博弈控制模型,并提出了基于拍照法的停车时间采集方法和模型其他参数采集与计算方法,目的在于用模型求出每次相位切换时使联盟平均停车时间最短的绿灯时间。运用VBA对VISSIM软件进行二次开发,对基于相邻相位合作博弈的单信号交叉口实时滚动优化模型进行仿真。结果表明:此控制模型有良好的控制效果。

By deriving the formula of average parking time of each approach when phase exchanged,we proved that there is a game for the resource of green between green phase and red phase. On this basis,we established the cooperative game control model for the alliance that is made up of green light phase and the next green phase,and put forward a way of collecting parking time based on photography and the methods of collecting and calculating other parameters of the model,which is order to figure out the green time that makes the average parking of alliance shortest when the phase will be transited. The secondary development of VISSIM is performed using VBA,and the real-time rolling optimal control model based on the cooperation game of adjacent phases is simulated. The result shows that the model has good control effect.
