The invention relates to a pedestrian crossing signal control method based on radar detection, and the method comprises the steps: S1, a first radar determines the number of effective waiting pedestrians according to the waiting time of the pedestrians in a roadside waiting region, and then determines the maximum waiting time, and the maximum waiting time is configured to be that the larger the number of the effective waiting pedestrians detected by the first radar in the roadside waiting region is, the smaller the number of the effective waiting pedestrians is; the maximum waiting time is shorter; s2, determining the turn-on time of the passing phase signal lamp according to the maximum waiting time; and S3, determining the traffic capacity Ci of the pedestrian crossing area, and adjusting the traffic duration t of the traffic phase signal lamp according to the number P of the effective waiting pedestrians and the traffic capacity Ci. According to the invention, pedestrian state detection is carried out on pedestrian crossing key areas such as a roadside waiting area and a crossing channel area, pedestrian crossing demands, behavior characteristics and characteristics of a pedestrian crossing area are comprehensively considered, pedestrian waiting duration and pedestrian crossing duration are intelligently and dynamically adjusted, pedestrian crossing passage delay is reduced, and pedestrian crossing efficiency is improved. And the overall passing efficiency and quality are effectively improved.
本发明涉及一种基于雷达检测的行人过街信号控制方法,包括S1、第一雷达根据行人在路侧等待区内的等待时间确定有效等待行人数量,再确定最大等待时间,最大等待时间被配置为第一雷达检测到路侧等待区内有效等待行人的数量越多,则最大等待时间越短;S2、根据最大等待时间确定通行相位信号灯的开启时机;S3、确定人行横道区的通行能力Ci,根据有效等待行人数量P与通行能力Ci调节通行相位信号灯的通行时长t。本发明对路侧等待区与过街通道区等行人过街关键区域进行行人状态检测,综合考虑行人过街需求、行为特征与人行横道区本身的特征,智能化动态调整行人等待时长与行人过街时长,降低行人过街通行延误,有效提升整体通行效率和质量。
