基于粗糙集的道路交通事故预警算法研究

Forecasting Algorithm of Traffic Accident Based on Rough Set Theory

按照历史道路交通事故数据分析,把交通事故分为具有不同特征的道路交通事故类型,归纳造成不同特征的道路交通事故发生原因(人,道路,车辆,天气等),利用粗糙集理论在事故原因与事故类型之间建立一个映射规则,为道路交通事故的预警提出了既快又简的融合算法。通过安装在汽车上的算法数据库,建立道路交通事故监测预报系统,根据监测驾驶员可在事故来临之前做出正确的调控措施,把道路交通事故消灭在萌芽状态中。

Through analyzing the historical data of traffic accident,this paper divides traffic accidents into different type,and summarizes the reasons inducing traffic accident with different features(caused by human reason,road reason,car reason,weather reason).The authors establish a mapping rule between these reasons and traffic accident using rough set theory,and build a quick and easy fusion algorithm for warning of traffic accident.By using the algorithm database installed on the car,one can build a system to forecast traffic accidents,so the driver can make the correct regulative measure based on the monitor system and prevent the occurrence of traffic accident.
