基于RST的事故黑点成因实例分析

本文结合实例,首先,对交通事故的主要形态进行分析,在此基础上,运用巴雷特曲线对事故主要形态进行事故因素分析,得到交通事故黑点的主要影响因素;然后,对交通事故黑点的主要影响因素简单加权,得到一个粗略的因素影响度排序;最后,运用粗糙集算法再次对影响因素的重要度进行分析,确定事故因素及其重要程度排序。

Cause Analysis of the Traffic Black-spot Based on RST

Combining with the instance, the author used an analysis model, which integrates the existed traffic accidents’ data and factors, to search for traffic accidents black-spots. Furthermore, the main reasons of the traffic accident black-spots formation were analyzed with rough set. Through the simple weighted analysis of the traffic accident black-spots on the main factors we roughly sort the factors according the affecting degrees. Finally, the rough set algorithm was used to analyze the importance of the factors and the degree was determined.
