The invention discloses an intersection signal optimization method for a networked automatic driving mixed driving environment, and aims to fully mine data sources and provide a more flexible and effective signal timing scheme. The method mainly comprises the following steps of firstly, acquiring the speed information of a vehicle entering an intersection control area based on a fixed point detector, and preliminarily estimating time when the vehicle arrives at a stop line; secondly, vehicle information in a control area being updated in real time based on a network connection automatic driving vehicle movement detection technology, and meanwhile the expected time for the vehicle to arrive at a parking line being updated; then, obtaining all possible signal timing schemes based on a release phase conflict-free principle; and finally, traversing all the schemes and calculating delays, and selecting the scheme with the minimum delay as the optimal signal timing scheme of the intersection at the current moment.

    本发明公开了一种面向网联自动驾驶混行环境的交叉口信号优化方法,旨在充分挖掘数据来源,并提供更灵活有效的信号配时方案。主要步骤为:首先,基于固定点检测器获取车辆进入交叉口控制区的速度信息,初步估计车辆到达停车线的时间;其次,基于网联自动驾驶车辆移动检测技术实时更新控制区内车辆信息,同时更新车辆预期到达停车线的时间;之后,基于放行相位无冲突原则得到所有可能的信号配时方案;最后,遍历所有方案并计算延误,选择延误最小的方案作为当前时刻交叉口最优信号配时方案。
