摘要:
为了提高城市干道在大型活动交通消散过程的控制效率,利用能够反映交通流动力学特性的元胞传输模型CTM实现消散干道交通信号优化控制.基于CTM建立了消散干道单向交通动力学模型,提出了基于滚动周期的干线模糊控制优化方法,通过实时调整主路绿灯时间从而实现绿波控制路段总延误最小的优化目标.对一个由4个路口组成双向六车道干线道路算例进行仿真,在消散干道主路输入流量随时间变化的情况下,采用各路口绿灯时间一致的控制方案与各路口变化绿灯时间即优化控制方案2种情况下,主路消散方向上车辆总延误分别为4 254和3 825 s.算例结果表明,优化方案对于减少主路消散方向的交通流总延误具有较好的控制效果.
Abstract:
The cell transmission model(CTM)which can describe dynamic character of traffic flow has been adopted in optimizing the traffic trunk line control under special events to improve the controlling efficiency. Based on the cell transmission model, a traffic dynamics model for trunk is put forward, and a fuzzy optimization method based on the roll cycles is advanced. By adjusting the green time of main road, the whole delay time of the controlling trunk can be reduced. Considering a six-lane traffic line combined with four crossings, the whole delay time of the controlling trunk are respectively 4 254 s and 3 825 s in fixed control scheme and optimized scheme when the importing traffic of the main road is variational. Thus the optimization method is proved to be more effective than the traditional one.
