公路交通违法行为与事故形态间的灰色关联分析

针对超速、超载、随意变更车道等公路交通违法行为频发现象,本文运用灰色关联分析理论,建立起公路事故频数与事故形态间的灰色关联分析模型。利用公路主要违法行为及追尾、侧翻、撞击护栏等事故形态数据,计算它们与事故形态的灰色关联度,确定了影响事故形态的关联度排序。

In view of the frequent occurrence of highway traffic violations such as speeding,overloading and changing lanes randomly,this paper uses the grey correlation analysis theory to establish a grey correlation analysis model between the frequency of highway accidents and accident forms.Based on the data of main illegal behaviors on the highway and the accident forms such as rear-end collision,rollover and impact on guardrail,the grey correlation degree between them and accident forms is calculated,and the ranking of the correlation degree influencing accident forms is determined.
