The invention discloses a self-adaptive signal control method for pedestrian traffic. The method comprises the following steps: S1, obtaining pedestrian traffic flow in each time period in each entrance direction and real-time pedestrian traffic flow on a zebra crossing; s2, generating a data matrix according to historical pedestrian traffic; s3, predicting a data matrix according to the generated data matrix by adopting a time sequence prediction method; s4, performing time sequence clustering on the obtained prediction data matrix, solving an optimal clustering point, and obtaining all classification numbers and classification sequences; s5, calculating the classified prediction data matrix, and obtaining the predicted pedestrian traffic flow; s6, the pedestrian crossing time is calculated, and the signal lamp control time in each direction in each time period is set by combining the predicted pedestrian traffic flow and the pedestrian crossing time; s7, comparing the real-time pedestrian traffic flow with the predicted pedestrian traffic flow at the end of the green light in each time period, and adjusting the signal lamp control time according to the comparison result; after real-time green light detection is finished, according to whether pedestrians stay on the zebra crossing, prediction data and real-time data are compared, green light time is selectively prolonged, and the traffic requirements of the pedestrians are fully met.

    本发明公开了一种行人交通的自适应信号控制方法,包括以下步骤:S1:获取各个进口方向上各个时段行人通行流量及斑马线上的实时行人通行流量;S2:根据历史行人通行流量生成数据矩阵;S3:采用时间序列预测方法,根据生成的数据矩阵预测数据矩阵;S4:对得到的预测数据矩阵进行时序聚类,求取最优聚类点,得到所有分类数和分类序列;S5:计算分类后的预测数据矩阵,获得预测行人通行流量;S6:计算行人过街时间,结合预测行人通行流量和行人过街时间,设置各个时段各个方向的信号灯控制时间;S7:各个时段的绿灯末时,将实时行人通行流量与预测行人通行流量作比较,根据比较结果调整信号灯控制时间;实时检测绿灯结束后,根据斑马线是否存在滞留行人,将预测数据与实时数据做对比,选择性进行绿灯时间延长,充分满足行人交通需求。
