The invention discloses an intersection signal lamp adaptive control method based on a radar detector, and relates to the technical field of traffic, and the method comprises the steps: monitoring the number of real-time vehicles in the current release direction of an intersection through the radar detector, and determining a green light demand degree index of the current release phase; meanwhile, the vehicle queuing length of each current waiting direction of the intersection is monitored through a radar detector so as to determine the red light urgency degree index of each current waiting phase, and phase switching is achieved as soon as possible when the red light urgency degree index of the current waiting phase exceeds the green light demand degree index of the current release phase. According to the method, comparative analysis is carried out based on real-time vehicle data to carry out automatic phase switching so as to coordinate traffic flows in different directions and realize asymmetric phase release, so that the pressure in each direction is equally distributed and the load is balanced, and the traffic efficiency of the traffic flows is improved.
本申请公开了一种基于雷达检测器的交叉口信号灯自适应控制方法,涉及交通技术领域,该方法通过雷达检测器监测交叉口的当前放行动向的实时车辆数并确定当前放行相位的绿灯需求度指数,同时通过雷达检测器监测交叉口的每个当前等待动向的车辆排队长度以确定各个当前等待相位的红灯紧迫度指数,在当前等待相位的红灯紧迫度指数超过当前放行相位的绿灯需求度指数时尽快实现相位切换。该方法基于实时的车辆数据进行比较分析进行自动化的相位切换,以协调不同动向的车流量,实现不对称式相位放行,使得各动向压力均分负载均衡,提高车流的通行效率。
