The invention discloses an intersection passing control method and device, and relates to the technical field of intelligent traffic. The method mainly comprises the steps of obtaining a similar historical period of a prediction period, and collecting historical period data of the similar historical period; wherein the historical cycle data represents intersection passing data of similar historical cycles; obtaining a historical cycle passing strategy corresponding to the similar historical cycle by adopting a genetic algorithm based on the historical cycle data; and taking the historical period passing strategy as an intersection passing strategy of the prediction period, and controlling the actual vehicle speed and the actual traffic signal lamp duration of the prediction period based on the intersection passing strategy. The optimal historical period passing strategy of the whole scene can be obtained through the genetic algorithm, the traffic jam problem is effectively solved, and the intersection passing efficiency of the prediction period is improved. Through mutual cooperation of the vehicle wireless communication technology and the genetic algorithm, unified planning and accurate time control can be performed on the vehicle speed and the traffic signal lamp duration at the intersection.

    本发明公开了一种路口通行控制方法及装置,涉及智能交通技术领域。该方法主要包括:获取预测周期的相似历史周期,采集相似历史周期的历史周期数据;其中,历史周期数据表征相似历史周期的路口通过数据;基于历史周期数据采用遗传算法得到相似历史周期对应的历史周期通过策略;将历史周期通过策略作为预测周期的路口通过策略,并基于路口通过策略对预测周期的实际车辆速度和实际交通信号灯时长进行控制。通过遗传算法可以得到全场景最优的历史周期通过策略,有效的解决交通堵塞问题,提高预测周期的路口通行效率。通过车用无线通信技术与遗传算法相互配合,可以对路口的车辆速度和交通信号灯时长进行统一规划、精准控时。
