The invention discloses a highway exit ramp confluence point sensing signal control method and system, and a medium. The method comprises steps of obtaining the vehicle queuing detection results of a first queuing detector, a second queuing detector and a third queuing detector, and enabling the first queuing detector to be arranged at the joint of an exit ramp and an urban road, the second queuing detector being arranged at an exit toll station connection ramp, and the third queuing detector being arranged at an exit ramp of an expressway main line; formulating a signal timing scheme according to the traffic condition of the signalized intersection and the vehicle queuing detection result of the first queuing detector; and controlling the vehicle release rate of the exit toll station according to the vehicle queuing detection results of the second queuing detector and the third queuing detector. By adjusting the traffic flow release sequence and release time of the two confluence ramps, traffic flow interlacing of the toll square is reduced, and toll station passing efficiency is improved.
本发明公开了一种高速公路出口匝道合流点感应信号控制方法、系统及介质,所述方法包括:获取第一排队检测器、第二排队检测器和第三排队检测器的车辆排队检测结果,所述第一排队检测器设置在出口匝道与城市道路衔接处,所述第二排队检测器设置在出口收费站衔接匝道处,所述第三排队检测器设置在高速公路主线出口匝道处;根据信号交叉口交通状况以及第一排队检测器的车辆排队检测结果,制定信号配时方案;根据第二排队检测器和第三排队检测器的车辆排队检测结果,控制出口收费站车辆放行速率。本发明通过调整两条合流匝道的车流放行顺序和放行时间,减少收费广场车流交织,提高收费站通行效率。
