Abstract This research analyzed the number of pedestrian traffic accidents before and after the pedestrian priority street project was introduced by the Seoul Metropolitan Government in 2013; the Project has since been implemented nationwide. Research has not been carried out much to analyze the effects of the introduction of pedestrian priority street projects, especially how much the reduction of pedestrian traffic accidents has been made, which is the most important goal of the pedestrian priority street project, and how the creation of pedestrian priority streets affects pedestrian traffic accidents. The Project uses the Traffic Authority’s Traffic Accident Analysis System (TAAS) to identify the physical factors involved in reducing pedestrian traffic accidents, and the Poisson regression model to verify the Project’s effectiveness and to prepare detailed improvement measures. Toward this end, the Seoul Metropolitan Government analyzed the factors affecting the number of pedestrian traffic accidents before and after the Project using the T-Test, and the number of pedestrian traffic accidents through Poisson regression analysis. The T-Test analysis showed statistically significant results, and the Poisson regression analysis showed that commercial areas, population density, floating population, road width, one-way traffic, crosswalk density, and closed-circuit television (CCTV) presence all were land-use characteristics that had an effect on pedestrian safety. These findings should be considered not only for pedestrian convenience or budget, but also for their effect on pedestrian safety when making land-use or installation decisions.
