The invention relates to the technical field of vehicle-road cooperation, in particular to a roadside system for prompting passing vehicles when pedestrians cross a street, which comprises the following components: C1, a pedestrian detection triggering unit: when pedestrians, non-motor vehicles and other targets pass through a detection area, a thunder-vision fusion all-in-one machine sends out an early warning signal, finally, the information is transmitted to the vehicle early warning prompt unit and the RSU through two information links. C2, a vehicle early warning prompt unit: after the vehicle early warning prompt unit receives the control information, the vehicle early warning prompt unit is linked with an LED high-brightness indication board to pop up preset early warning text information, and controls the lamp board to keep flickering or normally lighting in a certain period; C3, a RSU data communication unit: the data is sent to a cloud platform and a vehicle-mounted OBU when the RSU receives effective data, and the cloud platform and the vehicle-mounted OBU can receive and prompt the same early warning information as roadside facilities in real time; and after the pedestrian passes, the early warning signal disappears, the highlight lamp board and the LED high-brightness indication board are recovered to the initial state, and the RSU does not send early warning information any more.
本发明涉及车路协同技术领域,尤其为一种行人过街时提示过往车辆的路侧系统,包括以下组成部内容:C1,行人检测触发单元:当有行人和非机动车等目标通过检测区域时,雷视融合一体机发出预警信号,最终通过两条信息链路分别传输至车辆预警提示单元和RSU;C2,车辆预警提示单元:车辆预警提示单元接收到控制信息后,联动LED高亮度指示牌弹出预设的预警文本信息,并控制灯牌在一定周期内保持闪烁或常亮;C3,RSU数据通信单元:当RSU接收到有效数据时,将数据分别发送至云平台和车载OBU,云平台和车载OBU可实时收到并提示与路侧设施相同的预警信息;行人通过后,预警信号消失,高亮灯牌和LED高亮度指示牌恢复至初始状态,RSU不再发送预警信息。
