基于交通流微观仿真的交叉口控制模型分析

Analysis of Control Model at Intersections Based on Traffic Flow Simulation

通过对信号交叉口的车辆发生、车道选择、期望车速、信号控制等微观仿真模型的分析,有必要建立以交通延误为交通效益指标的控制方案,实现交叉口多相位、配时参数可变的可视化控制,并进行行车延误指标评价。

By analyzing on microcosmic simulation models of occurring vehicle, choosing lane, expecting speed and signal controlling at signalized intersections, it is necessary to set up control schemes with delays being transportation performance criterion. The system carries out visual controlling which consists of multi-phases and adjustable parameters, and evaluates transportation delays as criterion in the end.
