The invention discloses a vehicle-road cooperation type pedestrian crossing active safety early warning system which can be suitable for two scenes of signal control intersections and road section crossing channels so as to solve traffic conflicts caused by unclear road right of pedestrians and vehicles. The system comprises a detection module, a control module, an early warning module and a wireless communication module. The detection module is composed of a frequency modulation continuous wave millimeter wave radar and a high-definition camera, and achieves a vehicle and pedestrian detection function. The control module comprises two groups of micro-control units which are used for respectively controlling early warning condition judgment and intelligent zebra crossing LED lamp groups to be turned on by changing colors; the early warning module comprises an intelligent zebra crossing provided with an LED lamp and a voice prompt pile, and early warning can be conducted from the visual angle and the listening angle. The wireless communication module takes an IoT unit solidified in the wireless communication module as a core to realize information exchange in a region. The method can achieve the bidirectional early warning of pedestrians and vehicles, and is of practical significance for the reduction of human-vehicle conflicts.

    本发明公开了一种车路协同式的行人过街主动安全预警系统,可适用于信控交叉口和路段过街通道两种场景,以解决行人与车辆因路权不明确而导致的交通冲突。该系统包括检测、控制、预警、无线通信,四个模块。检测模块由调频连续波毫米波雷达和高清摄像机组成,实现车辆与行人检测功能;控制模块包括两组微控制单元,分别控制预警情况判断和智能斑马线LED灯组变换颜色启亮;预警模块包括装有LED灯的智能斑马线和语音提示桩,可分别从视、听两个角度进行预警;无线通信模块以固化于内部的IoT单元为核心实现区域内信息交换。本发明可对行人和车辆双向预警,对减少人‑车冲突具有现实意义。
