Abstract
During the past decades, the paradigm of transportation planning has shifted from automobile-centered to pedestrian-oriented perspectives in Korea. In the context of this paradigm shift, this study examines the relationships between physical environmental factors and the pedestrian traffic accidents. Using the 2014 Traffic Accident Analysis System (TAAS) data, including traffic accidents of pedestrians in Seoul, Korea, we identify important physical environmental variables that influence pedestrian traffic accidents. With negative binomial regression models by the level of injury, we analyze demographic and socioeconomic factors, road physical environments, and land-use factors. Key findings and implications can be organized into following four parts. First, the number of lanes shows negative associations with pedestrian safety. Road diet projects such as lane reduction and narrow road may improve pedestrian safety. Second, although the median exclusive bus lane is convenient and beneficial to citizens, it has negative impacts to pedestrian’s safety. Public policies should be considered to improve pedestrian’s safety near the median exclusive bus station. Third, high density and mixed land use have negative impacts on pedestrian safety. The compact development strategies with transit-oriented development should consider pedestrian’s safety and walking-friendly environment. Finally, we suggest the policy implications for safer walking environments.
