The invention relates to the field of traffic lights, in particular to a sidewalk traffic light capable of dynamically identifying and intelligently adjusting, which is used for solving the problems of poor real-time performance and low passing efficiency of a timing traffic light and potential safety hazards caused by inconvenience in setting the traffic light at a part of intersections with small pedestrian flow. Pedestrians and vehicles are dynamically recognized through the traffic light, the intelligent decision-making unit analyzes the vehicle running speed, the vehicle number and the pedestrian number, the vehicle passing efficiency when the number of pedestrians is small and the pedestrian passing efficiency when the number of vehicles is small are guaranteed, and waste of the green light duration existing in transmission of the timing traffic light is avoided; the decision checking unit obtains the number of people passing through the sidewalk during the green light period and the number of vehicles overstocked on the motor vehicle lane, and the green light duration of the sidewalk in the time period is further adjusted through analysis of the decision checking unit, so that different time periods have different traffic light durations, and it is ensured that the traffic lights can better meet the actual traffic condition. The passing efficiency is improved.
本发明涉及交通信号灯领域,用于解决定时制红绿灯实时性差,通行效率低以及部分人流量小的路口不便于设置红绿灯存在安全隐患的问题,具体为一种动态识别及智能调整的人行道交通信号灯;本发明是通过红绿灯动态识别行人和车辆,智能决策单元对车辆行驶速度、车辆数量和行人数量进行分析,保证在行人较少时的车辆通过效率、车辆较少时的行人通过效率,避免传动定时制红绿灯存在绿灯时长浪费,而决策核对单元获得绿灯期间人行道的通行人数和机动车道的车辆积压数量,通过决策核对单元的分析进一步调整该时间段的人行道的绿灯时长,使得不同时间段具有不同的红绿灯时长,保证红绿灯能够更加符合实际的通行情况,提高通过效率。
