The invention discloses a street-crossing signal control method for vulnerable pedestrian groups. The street-crossing signal control method comprises the following steps: establishing a corresponding pedestrian individual tag data set; outputting pedestrian individual coordinate information by using a video detector; calculating information in the current pedestrian individual matrix; analyzing the video by using a deep learning method, classifying pedestrians, and calculating pedestrian remaining street-crossing time for current vulnerable pedestrians; when the pedestrian crossing phase is green, the video detectors at the two ends of the zebra crossing are used for conducting form recognition on all pedestrian individuals, and if vulnerable pedestrian individuals exist, the street crossing remaining time of the maximum vulnerable pedestrian group is calculated; the output result of the video detector in each direction is transmitted to the identification auxiliary system, and the system transmits the green flash prolonged time to the signal machine. According to the invention, traffic accidents caused by the fact that vulnerable pedestrian groups do not cross the street in time are avoided, the data of each networked assembly intersection are collected, the data sample size is improved, and cluster training learning is carried out.
本发明公开了一种针对弱势行人群体过街信号控制方法,包括步骤:建立对应的行人个体标签数据集;利用视频检测器输出行人个体坐标信息;计算当前行人个体矩阵中的信息;利用深度学习方法对视频进行分析,对行人进行分类,对当前弱势行人个体计算其行人剩余过街时间;在行人过街相位绿灯时,利用斑马线两端的视频检测器对所有行人个体进行形态识别,若存在弱势行人个体,计算最大弱势行人群体过街剩余时间;各方向视频检测器的输出结果传输到识别辅助系统中,该系统将绿闪延长时间传输到信号机。本发明避免弱势行人群体未及时完成过街而导致的交通事故发生,收集各个联网装配路口的数据,提高数据样本量,并进行集群训练学习。
