面向现场要素关联的车辆冲撞行人案件研判系统构建

Constructing the Analysis-judgment System of Connecting the Scene Elements into Course of Vehicle Crashing to Pedestrian

车辆碰撞行人事故是中国死亡人数最多的道路交通事故形态,一些车辆冲撞人群的恶性案件也时有发生,影响恶劣并危害公共安全,因此对车辆冲撞行人事件进行深入研究分析是当务之急。当前对车辆冲撞案件的分析缺少实用化的动力学模型和可视化研判方法。面向公共安全及案件侦破处理的实际需要,为了深入分析和研判典型车辆冲撞案件的过程,本文建立了车辆冲撞案件的动力学模型与分析研判体系,并将其应用于现场要素的关联及分析,综合利用现场痕迹、人体损伤和车辆损坏等典型信息辅助进行人车接触过程分析,实现从车辆冲撞案件现场信息获取到动力学模型构建及案件动态可视化研判的全过程,并以实际的案例分析进行验证。研究结果为车辆冲撞行人案件的应急处置与再现提供了参考。

Vehicle-pedestrian crashes take up the majority of casualties of traffic accident.Sometimes,events of vehicle colliding into the crowd are reported,leaving bad social impacts and severe criminal incidents for the public security to urgently investigate and dispose.Therefore,it is essential to conduct in-depth scrutiny and analysis about the involving vehicles and individuals.However,the present available approaches lack of dynamic deciphering and visualization into analyzing the course of vehicle-pedestrian collision.Oriented to the actual demands of public safety and the detections of relevant criminal cases,a new analysis-judgment system was here set up through constructing the dynamic models for connecting the scene main factors into the course of related crash so that the investigated case can be concretely unveiled of its specific junctures.With comprehensive usage of the human inuries,vehicle damages and other typical traces/marks emerged from human bodies and vehicle in one crash process,the established system is able to handle a case over its whole process from collecting scene information through constructing dynamic models to visualizing the specific junctures.All the analysis and judgement can be reversely verified with the actual case and/or simulations.Moreover,the system can also provide references with pertinent precognition for emergency disposal and reconstruction of vehicle-pedestrian collision.
