| Abstract |
The objective of this study is to analyze the characteristics of street environment affecting pedestrian traffic accidents and to suggest the policy implications for pedestrian safety. This study analyzes the Traffic Accident Analysis System (TAAS) 2014 data in Seoul with the street segment analysis unit and the spatial statistics. For handling spatial autocorrelation which exists in pedestrian traffic accidents, spatial regression model is used. The results are as follows. First, traffic volume and pedestrian volume are significant factors for pedestrian traffic accidents. Second, pedestrian traffic accidents are high near public transportation facility, elementary school, and commercial street. Third, school zone and crosswalk are still not safe places for pedestrians, so public policies should be addressed to reduce pedestrian traffic accidents near these facilities. Finally, 3-way intersections adjacent to main street are associated with higher pedestrian traffic accidents. We suggest pedestrian safety facilities to prevent pedestrian's jaywalking around these intersections and public awareness programs to reduce pedestrian's traffic accidents. |
