The invention relates to a safety early warning system and method for a signal-control-free intersection. The system comprises a vehicle detection module, a wireless communication module, an information processing module, an early warning information issuing module and a power supply module. The safety early warning system for the signal-control-free intersection is installed on the right side of a road in the direction of each entrance of the intersection. When the vehicle detection module in a certain direction detects that a vehicle is about to enter the intersection, information is transmitted to other interconnected early warning systems at the intersection through the wireless communication module; and after the information processing module receives the information transmitted by the wireless communication module, if the current vehicle detection module also detects that a vehicle arrives within 5 seconds through judgment, early warning information is issued through the early warning information issuing module, and the current vehicle is reminded of the vehicle coming direction of the intersection in front of the current vehicle. According to the method of the invention, real-time and more accurate early warning information can be provided for the vehicle which is about to pass through the signal-control-free intersection, and the driving safety is improved.

    本发明涉及一种无信控交叉口安全预警系统及方法,包括车辆检测模组、无线通信模组、信息处理模组、预警信息发布模组、供电模组。无信控交叉口安全预警系统安装在交叉口每个进口方向的道路右侧;当某一方向的车辆检测器模组检测到有车辆即将进入交叉口时,便通过无线通讯模组将信息传递给交叉口其他互联的预警系统;信息处理模组在接收到无线通讯模组传递的信息后,经判断,若当前车辆检测模组在5秒内也检测到有车辆到来,则通过预警信息发布模组发布预警信息,提醒当前车辆前方交叉口的来车方向。本发明可为即将通过无信控交叉口的车辆提供实时更为精确的预警信息,提高行车安全性。
