The spatial characteristics of bicycle-to-person collisions: a focus on bicycle paths of the Han River Park in Seoul, Korea

Recently, as the number of cyclists has grown in Seoul, Korea, bicycle traffic accidents have also increased rapidly. Most precedent research concerning bicycle traffic accidents has focused on the cases where motor vehicles have injured cyclists. Unlike preceding studies, this study focuses on the cases where bicycles have collided with pedestrians. The purpose of this study is to identify the spatial characteristics of the bicycle-to-person collisions caused by bicycles. Binomial Logistic Model is used to identify the spatial relationships of bicycle-to-pedestrian collisions. For the analysis, the entire Han River Park is broken down into 50 × 50 m grids, which become the units of analysis of this study. The target period for the analysis is set from 2014 to 2016. Dependent variables are accident points in the Han River Park. As the independent variables, the variety of spatial and physical factors of the Han River Park are considered. The model shows that the crosswalks, speed restriction features, street furniture, floating population, and bicycle rental shops in the Han River Park are significant factors relating to bicycle-to-pedestrian collisions.Highlights Bicycle-to-person collisions are also on the rise as the use of bicycles increasesWhat are the physical and spatial factors that affect bicycle-to-person collisions?Binomial logistic regression was used to determine factors related to collisionsCrosswalk, speed restriction facility and street furniture are significant variables
