The invention relates to a public transport signal priority implementation method and system based on artificial intelligence vehicle-road cooperation. The method comprises the steps of receiving public transport vehicle information; determining a priority level; receiving current signal lamp information; calculating a recommendation speed; if the recommended speed does not exceed the preset speedvalue, sending the recommended speed and the current signal lamp information to the vehicle-mounted equipment; if the recommended speed exceeds the preset speed value, optimizing the current signal lamp information, and recalculating the recommended speed until the recommended speed does not exceed the preset speed value; calculating a per capita delay value according to the current signal lamp information and the optimized signal lamp information; and if the difference between the per capita delay value of the optimized signal lamp information and the per capita delay value of the current signal lamp information is not greater than a preset allowable value, sending the optimized signal lamp information to signal lamp control equipment. According to the method and the system, signal priority processing of a plurality of public transport vehicles can be realized, and adverse effects on overall traffic are reduced.

    本发明涉及基于人工智能车路协同的公交信号优先实现方法和系统,该方法包括:接收公交车辆信息;确定优先等级;接收当前信号灯信息;计算推荐速度;如推荐速度未超过预设速度值,则向车载设备发送推荐速度和当前信号灯信息;如推荐速度超过预设速度值,优化当前信号灯信息,重新计算推荐速度,直至推荐速度不超过预设速度值;根据当前信号灯信息和所述优化后信号灯信息计算人均延误值;如优化后信号灯信息的人均延误值与当前信号灯信息的人均延误值之差不大于预设允许值,向信号灯控制设备发送优化后信号灯信息。本发明的方法和系统能够实现多个公交车辆的信号优先处理,且减少对整体交通的不利影响。
