The invention discloses a traffic safety evaluation method, system and device based on traffic conflict prediction, and the method comprises the steps: obtaining a corresponding reconstruction set group and a non-reconstruction set group of a traffic road in a limited region range, obtaining the data in a preset period corresponding to each set group in a historical time range, and obtaining a reconstruction set group and a non-reconstruction set group; and screening the continuous collision duration in the group to obtain extreme value collision duration distribution, applying the obtained data and the extreme value collision duration distribution to obtain a constructed traffic safety evaluation model, and applying the traffic safety evaluation model to obtain a traffic safety evaluation result. According to the invention, the traffic roads are evaluated in groups, so that the deviation of traffic safety evaluation results is reduced, and the accuracy and reliability of traffic safety evaluation are greatly improved.
本发明公开了一种基于交通冲突预测的交通安全评价方法、系统及装置,包括获取限定区域范围内交通道路的对应改造集合组和非改造集合组,在历史时间范围内,获得各个集合组对应的预设周期内的数据,对分组中的持续碰撞时长进行筛选,获得极值碰撞时长分布,并对获取数据、以及极值碰撞时长分布进行应用,得到构建好的交通安全评价模型,应用交通安全评价模型获得交通安全评价结果。通过本发明中对交通道路进行分组评价,降低交通安全评价结果偏差,大幅提高交通安全评价的准确性和可靠性。
