基于关联规则的重大道路交通事故影响因素分析

相比于一般交通事故,重大道路交通事故的特征及其影响机理会有所差异,本文旨在研究重大道路交通事故的分布特征及其主要影响因素。收集2014至2018年的重大道路交通事故数据,从驾驶员行为、车辆状况、道路线形和时空分布方面对重大道路交通事故的基本特征进行分析,采用关联规则技术深入挖掘重大道路交通事故多因素的影响机理。从人、车、道路和环境四个方面,重点讨论了重大道路交通事故中的两因素和三因素交互作用的影响机理,并据此提出了针对性的事故预防措施。

Influencing Factor Analysis of Extraordinarily Severe Road Accident Based on Association Rules

There is a difference in the characteristics and influencing mechanism between serious traffic accidents and general traffic accidents on urban roads.The purpose of this paper is to study the distribution characteristics and main influencing factors of serious road accidents.We collect the accident data from 2014 to 2018 and analyze the basic characteristics of serious road accidents from four aspects including road user behavior,vehicle condition,road geometry,temporal and spatial characteristics.Furthermore,the technology of association rules is used to reveal the influencing mechanism of multi-factor interactions in serious traffic accidents.The interactions among two and three kinds of influencing factors are discussed from four aspects including drivers,vehicles,roads and environments.Finally,the corresponding countermeasures of accident prevention are put forward.
