The invention discloses a method, a system and a device for judging and positioning a traffic accident in a non-monitoring road section, which specifically comprise the following steps of: dividing aroad network into road sections based on road network monitoring points and relative spatial positions thereof, and monitoring vehicle flow entering the road sections, vehicle speed, vehicle flow leaving the road sections and vehicle speed at two ends of the road sections; performing road section two-way modeling, and learning road information of a specific road section through neural network model training parameters: inputting change vectors of vehicle speeds of monitoring points at two ends at different moments and change vectors of flow at different moments, and standardizing and mapping data of four time sequences to a [0, 1] interval according to the first n moments; and recording the monitoring state at the current moment. According to the method, the monitoring data are adopted torealize judgment and positioning of unmonitored road section accidents.
本发明公开了一种非监控路段判断与定位交通事故的方法、系统及装置,具体为:基于路网监测点以及其相对的空间位置,将路网进行分割成路段,并监测路段两端进入车辆流量、车速、离开车辆流量、车速;进行路段双向建模,对于特定路段的道路信息通过神经网络模型训练参数中学习:输入两端的监控点的车速在不同时刻的变化向量以及流量在不同时刻的变化向量,将四个时序的数据按照前n个时刻标准化映射到[0,1]区间;并记录为当前时刻的监控状态。本发明采用监控数据实现对未监控路段事故进行判断与定位。
