초록

본 연구는 이처럼 보행자 교통사고 심각성에 있어 차이를 보이는 주간과 야간 시간대의 보행자 교통사고를 대상으로 분석을 진행하고자 한다. 해당 시간대에 발생하는 보행자 교통사고를 Point 단위로 미시적으로 분석해서 보행자 교통사고의 사고심각성 요인에 대해 규명하고 이에 대한 정책적 시사점을 제공하는 데 이 연구의 목적이 있다.

영어초록

Although the pedestrian crash in Korea is gradually decreasing, it is still high compared to major developed countries. The pedestrian crash is known to be more dangerous in the nighttime than in the daytime. However, there have been few studies on factors affecting the severity of pedestrian crash at various times including daytime and nighttime. Using the data of the Traffic Accident Analysis System (TAAS) from 2015 to 2017, this study analyzed 16,650 observations including 8,265 cases of daytime accidents and 8,385 cases of nighttime accidents. This study examines the factors affecting the severity of pedestrian crash during the daytime and nighttime and provides policy implications for pedestrian safety. Analysis results from logistic regression models confirmed that conventional variables such as demographic characteristics, weather, and population density showed expected outcomes. In particular, the youth and the elderly drivers are more likely to be associated with the severity of pedestrian crash. In addition, traffic density is strongly associated with the severity of pedestrian crash. This outcome indicates that traffic volume and speed are crucial factors to the severity of pedestrian crash. This study also identified disparate physical factors that affect pedestrian crash severity between the daytime and nighttime. Road characteristics such as one-way below two lanes, exclusive median bus lane crosswalk showed strong associations with the severity of pedestrian crash. Finally, this study suggested policy implications to promote pedestrian safety.
