本发明公开了一种考虑自动驾驶专用相位的交叉口交通控制方法,针对自动驾驶车辆与人工驾驶车辆混合行驶的交叉口。首先,本发明采集交叉口各进口方向的车道数、自动驾驶车辆和人工驾驶车辆的初始交通量;其次,考虑自动驾驶车辆穿插式通行,建立自动驾驶专用相位通行能力的预测模型,构建车道布设模型;然后,设计考虑自动驾驶专用相位的相位结构,建立信号配时模型,分配各进口车道的最佳交通量;最后,以交叉口通行能力最大化为控制目标,优化获得交叉口信号配时方案。本发明基于自动驾驶专用相位,合理分配自动驾驶车辆和人工驾驶车辆的通行权,实现自动驾驶车辆和人工驾驶车辆的分离控制,提高交叉口通行能力。
The invention discloses an intersection traffic control method considering an automatic driving special phase. The intersection traffic control method aims at an intersection where automatic driving vehicles and manual driving vehicles are in mixed driving. Firstly, the number of lanes in each entrance direction of an intersection and the initial traffic volume of automatic driving vehicles and manual driving vehicles are collected; secondly, considering the alternate passage of the automatic driving vehicle, establishing a prediction model of the passage capacity of the special phase for automatic driving, and constructing a lane layout model; then, designing a phase structure considering a phase special for automatic driving, establishing a signal timing model, and distributing the optimal traffic volume of each entrance lane; and finally, optimizing to obtain an intersection signal timing scheme by taking intersection traffic capacity maximization as a control target. Based on the automatic driving special phase, the passing right of the automatic driving vehicle and the manual driving vehicle is reasonably distributed, the separation control of the automatic driving vehicle and the manual driving vehicle is realized, and the traffic capacity of the intersection is improved.
