The invention discloses a road traffic risk early warning method and system based on a driving safety field. The method comprises the following steps: determining a risk F caused by a target vehicle on a target road section to a road traffic environment; determining the risk U caused by all vehicles on the target road section to the road traffic environment; the risk level of the risk F is judged, and if the risk F reaches the danger level, early warning information is sent to a driver of the target vehicle; the risk level of the risk U is judged, and if the risk U reaches the danger level, early warning information is sent to drivers of all vehicles. According to the invention, global monitoring analysis can be carried out on people-vehicle-road-environment in a whole area, timely early warning for a driver is realized, the road traffic safety is improved, and the road traffic accident rate is reduced.
本发明公开了一种基于行车安全场的道路交通风险预警方法及系统,包括:确定目标路段目标车辆对道路交通环境造成的风险F;确定目标路段所有车辆对道路交通环境造成的风险U;判断风险F所属的风险级别,若风险F达到危险级别,则向目标车辆的驾驶员发出预警信息;判断风险U所属的风险级别,若风险U达到危险级别,则向所有车辆的驾驶员发出预警信息。本发明能够对整体区域内的人‑车‑路‑环境进行全局监测分析,实现对驾驶员的及时预警,提高了道路交通安全性,降低了道路交通事故率。
