The invention relates to the technical field of signal lamp control equipment accessory devices, in particular to a signal lamp color real-time control device based on radar and video analysis fusion data. According to the system, real-time study and judgment can be carried out on the color of a signal lamp released at a current intersection through integrating exit lane overflow, entrance lane queuing over-limit/congestion data and lane-level real-time traffic flow state data collected by an intersection traffic radar, and whether green light keeping or green light switching is carried out or not is judged; the next operation phase is selected according to the traffic flow data collected by the traffic radar in real time, so that the complex traffic demand prediction and signal timing optimization model is eliminated, the responsible degree of the model is reduced, the matching degree of the operation scheme and the traffic demand is optimized, the working efficiency of the equipment is improved, the practicability is improved, and the application prospect is wide. The system collects exit lane overflow through an integrated intersection traffic radar.
本发明涉及信号灯控制设备附属装置的技术领域,特别是涉及一种基于雷达与视频分析融合数据的一种信号灯色实时控制装置,其可以通过系统通过集成路口交通雷达采集的出口道溢出、进口道车道排队超限/拥堵数据及车道级实时交通流状态数据对当前路口放行的信号灯色进行实时研判,判断是否进行绿灯保持或者是进行绿灯切换,同时在灯色切换时,依据交通雷达实时采集的交通流数据对下一个运行相位进行选择,以此来摆脱复杂的交通需求预测和信号配时优化模型,降低了模型的负责度,优化了运行方案和交通需求的匹配度,因此提高了设备的工作效率,从而增加了实用性,包括系统通过集成路口交通雷达采集的出口道溢出。
