本发明涉及交通事故分析技术领域,尤其涉及一种基于多元数据的交通事故分析方法及系统,本方法包括:根据相关性分析结果确定历史交通事故的影响因素并形成影响因素集;根据主成分分析方法确定实际影响因素集;根据实际影响因素集确定当前交通事故的表征倾向以控制采集无人机采集对应高速路段的交通视频,并确定各行驶车辆的行驶数据组以确定任意行驶车辆的驾驶表征趋势;根据隐性稳定趋势的行驶车辆的行驶数据锁定其在拥堵路段的位置,结合拥堵路段的位置关系控制通讯无人机的飞行预设位置采集拥堵视频,以确定拥堵原因;本发明根据历史交通事故分析事故影响因素并结合实时交通特征预测事故倾向,从而提高交通事故发生的及时性。
The invention relates to the technical field of traffic accident analysis, in particular to a traffic accident analysis method and system based on multivariate data, and the method comprises the steps: determining influence factors of historical traffic accidents according to a correlation analysis result, and forming an influence factor set; determining an actual influence factor set according to a principal component analysis method; the characterization tendency of the current traffic accident is determined according to the actual influence factor set so as to control the acquisition unmanned aerial vehicle to acquire the traffic video of the corresponding highway section, and the driving data set of each driving vehicle is determined so as to determine the driving characterization tendency of any driving vehicle; locking the position of the driving vehicle on the congested road section according to the driving data of the driving vehicle with the recessive stable trend, and controlling the flight preset position of the communication unmanned aerial vehicle to collect a congestion video in combination with the position relationship of the congested road section so as to determine the congestion reason; the accident influence factors are analyzed according to the historical traffic accidents, and the accident tendency is predicted in combination with the real-time traffic characteristics, so that the timeliness of the traffic accidents is improved.
