基于主成分分析的穿村镇公路事故影响因素分析

Analysis of Factors of Rural Traffic Accidents Based on Principal Component Analysis

对于道路行车安全与交通事故的研究是交通研究的重要方向之一,但对于穿村镇公路事故分析相对较少。文章从网络中获取中国山东省穿村镇公路交通事故数据,通过主成分分析法对穿村镇公路交通事故影响因素进行研究,发现穿村镇公路交通事故主要影响因素是交通控制状态、道路线形、路面坡度等因素。这些发现为改善穿村镇公路交通安全提供了重要依据。最终研究建议加强交通控制、优化道路设计,并考虑路面坡度,以降低交通事故的发生率。这将有助于确保驾驶者和行人在穿村镇公路上的安全出行。

The study of road safety and traffic accidents is one of the important directions of transportation research,but there are relatively few analyses of road accidents through villages and towns.In this paper,we obtained the traffic accident data of through-village town highway in Shandong Province,China,and studied the inf luence factors of through-village town highway traffic accidents through principal component analysis,and found that the main inf luence factors of through-village town highway traffic accidents are traffic control status,road alignment,roadway gradient,and other factors.These findings provide an important basis for improving the traffic safety of highways through villages and towns.The final study recommended better traffic control,optimized road design,and consideration of road gradient to reduce the incidence of traffic accidents.This will help to ensure the safe travel of motorists and pedestrians on roads through villages and towns.
