The invention discloses a road traffic accident monitoring and alarming method and system, and relates to the technical field of data processing. The method comprises the following steps: acquiring vehicle speed values, vehicle distance values and driving tracks of a plurality of vehicles on a road to be monitored; calculating a speed change rate according to the vehicle speed value of each vehicle, calculating a distance change rate according to the vehicle distance value of each vehicle, and calculating a vehicle transverse offset according to each driving track; when the speed change rate, the distance change rate or the vehicle lateral offset exceeds the corresponding standard threshold value, determining that a traffic accident occurs on the road to be monitored; receiving the lane occupancy rate, the traffic flow density and the average passing speed of the road to be monitored; and determining an accident grade corresponding to the traffic accident based on the lane occupancy rate, the traffic flow density and the average passing speed, and generating alarm information of the accident grade corresponding to the traffic accident. By implementing the technical scheme provided by the invention, the effect of improving the road traffic accident monitoring and alarming efficiency is achieved.

    一种道路交通事故监测报警方法及系统,涉及数据处理技术领域。该方法包括:获取待监测道路的多个车辆的车速值、车距值以及行驶轨迹;根据各车辆的车速值,计算速度变化率,根据各车辆的车距值,计算距离变化率,并根据各行驶轨迹,计算车辆横向偏移量;当速度变化率、距离变化率或车辆横向偏移量超出对应的标准阈值时,确定待监测道路发生交通事故;接收待监测道路的车道占用率、交通流密度以及平均通行速度;基于车道占用率、交通流密度以及平均通行速度,确定交通事故对应的事故等级,并生成交通事故对应的事故等级的报警信息。实施本申请提供的技术方案,达到了提高道路交通事故监测报警的效率的效果。
