The invention relates to a continuous intersection collaborative optimization method based on traffic flow arrival time prediction. The method comprises the following steps: step one, correcting a traffic flow discrete model Robertson; step two, according to a corrected Robertson discrete model, predicting the time when the traffic flow arrives at the intersection, and predicting a time period required by a motorcade to arrive at a downstream intersection; and step three, establishing a trunk line delay model according to a relationship between the time of traffic flow arrival at the intersections and starting and ending time of the intersection coordination phase green light, and optimizing a relative phase difference between the intersections. According to the invention, more vehicles can continuously pass through the adjacent intersections at one time, the delay of the whole trunk line is reduced, congestion on the trunk line is avoided, and the operation efficiency of the whole trunk line is improved.
本发明涉及一种基于车流到达时间预测的连续交叉口协同优化方法，包括以下步骤，1)对交通流离散模型Robertson进行修正；2)根据修正的Robertson离散模型，对车流到达交叉口的时间进行预测、以及预测车队到达下游交叉口所需的时间段；3)依据车流到达交叉口的时间与交叉口协调相位绿灯的开启与结束时间的关系，建立干线延误模型，优化交叉口之间的相对相位差。本发明使得更多的车辆能够连续一次性通过相邻交叉口，减少整个干线的延误，避免了在干线上发生拥堵，提高整条干线的运行效率。
