Abstract
In this study, our goal was to determine the impact of various risk factors on traffic accidents in the city of Shenyang, China, and to discuss the various common factors that influence pedestrian and non-motor vehicle accidents. A total of 1227 traffic accidents from 2015 to 2017 were analyzed, of which, 733 were accidents involving pedestrians and 494 were non-motor vehicle accidents. Among these traffic accidents, pedestrians and non-motor vehicle users had either minor or no responsibility. Sixteen influencing factors, including main responsible party attributes, pedestrian/non-motor vehicle user attributes, time attributes, space attributes, and environmental attributes were analyzed with regards to their impact on accidents using the binary logistic regression model (BLR) and the classification and regression tree analysis model (CART). Age, administrative division, and time of year were the three most common factors for pedestrian and non-motor vehicle accidents. For pedestrian accidents, the personal influencing factors of the main responsible party included illegal acts while driving and hit-and-run behavior. Factors affecting pedestrian and non-motor vehicle accidents also had different orders of importance.
Highlights
Traffic accidents pose a considerable threat to public health, and deaths resulting from traffic accidents have become a serious concern for society
Of all parties involved in traffic accidents, pedestrians and cyclists are more vulnerable as they have less protection than motor vehicle drivers
In binary logistic regression analysis (BLR), the impact on accidents was set as the interpreted variable, Y, with two possible values (0, 1)
Summary
Traffic accidents pose a considerable threat to public health, and deaths resulting from traffic accidents have become a serious concern for society. As World Health Organization statistics show, road traffic accidents have been a leading factor, resulting in the deaths of many people in the past twenty years [1]. Of all parties involved in traffic accidents, pedestrians and cyclists are more vulnerable as they have less protection than motor vehicle drivers. It is vital to study road traffic accidents, both non-motor vehicle and those involving pedestrians, to make our world safer and more sustainable. Many scholars have studied traffic accidents involving both pedestrians [2] and non-motor vehicles [3]. The analysis of the factors affecting the severity of traffic accidents is of great significance for the protection of the relatively more vulnerable groups that include pedestrians and non-motor vehicle users [4]
