The invention belongs to the field of intelligent transportation, and particularly relates to an intersection delay time optimization and speed guidance method for an intelligent network connection vehicle. The method comprises the following steps: constructing a Petri net model; numbering vehicles which are about to arrive at the intersection area, generating an intersection vehicle passing sequence according to the passing process of each vehicle passing through each road right point on the path of the vehicle, and decoding the intersection vehicle passing sequence into a transition sequence; the current transition sequence is detected, and if a deadlock phenomenon exists, the current transition sequence is repaired; input information of the vehicle is obtained, Delaytime is optimized, and finally speed regulation is carried out. And the optimal driving speed and passing time suggestions are provided for each intelligent network connection vehicle. The vehicle can pass through the intersection at the optimal speed on the premise of ensuring the safety and avoiding deadlock, so that the waiting time is effectively shortened, and the traffic jam is relieved.
本发明属于智能交通领域,具体涉及一种智能网联车的交叉口延迟时间优化与速度引导方法。本发明包括:构建Petri网模型;将即将到达交叉口区域的车辆进行编号并根据每一辆车经过其路径上的各个路权点的通行过程生成交叉口车辆通行序列,并解码成变迁序列;对当前变迁序列进行检测,如果存在死锁现象进行修复;获取车辆的输入信息,优化Delaytime,最后进行调速。为每辆智能网联车辆提供最优的行驶速度和通过时间建议。车辆能够在保证安全和避免死锁的前提下,以最优的速度通过交叉口,有效减少等待时间,缓解交通拥堵。
