The invention discloses an intersection bus signal priority control optimization method, and the method comprises the steps: selecting the weighted sum of the passenger delay of a bus, the passenger waiting delay of a downstream station and the per capita delay of other social vehicles to evaluate the priority level of a bus signal priority request, and comparing the priority levels of a pluralityof bus signal priority requests; and the problem of multi-bus signal priority request conflict at the intersection is solved. The method comprises the following steps of judging whether a bus can smoothly pass through an intersection, judging whether the bus runs according to a time table, determining a bus signal priority strategy and generating a priority request, judging whether a priority request conflict exists, formulating a priority request conflict resolution method and updating a signal timing scheme. The method is simple in design and easy to calculate; according to the method, after the conflict of bus signal priority requests is solved, the implementation effect of bus signal priority is greatly improved, and the punctuality rate and the service level of buses are improved, sothat more travelers are attracted to select buses to travel, the use of private cars is reduced, and the problem of urban traffic congestion is solved.

    本发明公开了一种交叉口公交信号优先控制优化方法,该方法选取公交车辆车上乘客延误、下游站点乘客等待延误和其他社会车辆的人均延误的加权和来评估公交信号优先请求的优先水平,通过对比多个公交信号优先请求的优先水平,解决了交叉口处的多公交信号优先请求冲突问题。本发明包括以下几个步骤:判断公交车辆是否能顺利通过交叉口、判断公交车辆是否按照时刻表运行、确定公交信号优先策略并产生优先请求、判断是否存在优先请求冲突、制定优先请求冲突解决方法、更新信号配时方案。本发明方法设计简单,易于计算;解决了公交信号优先请求冲突后,公交信号优先的实施效果将大大提高,提升了公交车辆准点率和服务水平,从而吸引更多的出行者选择公交出行,进而降低了私家车的使用,有助于缓解城市交通拥堵问题。
