Abstract

According to the statistics of the National Police Agency, red light running (RLR) crashes represent a significant safety issue throughout Korea. This study deals with the RLR crashes occurred at signalized intersections in Cheongju. The objectives of this study are to comparatively analyze the characteristics of between RLR crashes and the Non-RLR crashes, and to find out factors using a Binary Logistic Regression(BLR) model. In pursuing the above, the study gives particular attentions to testing the differences between the above two groups with the data of 2,246 RLR/ 3,884 Non-RLR crashes (2007-2011). The main results are as follows. First, many RLR crashes were occurred in the nighttime and in going straight. Second, the difference between RLR and Non-RLR crashes were clearly defined by crash type, maneuver of vehicle before crash, age of driver (30s, 50s), alcohol use and accident pattern. Finally, a statistically significant model (Hosmer and Lemeshow test : 7.052, p-value : 0.531) was developed through the BLR model.

경찰청 통계에 따르면, 우리나라에서 신호위반사고는 심각한 안전문제로 대두되고 있다. 본 연구에서는 청주시 신호교차로에서의 신호위반사고를 다루고 있으며, 연구 목적은 신호위반사고와 비신호위반사고의 특성을 비교분석하고 이항 로지스틱 모형을 이용하여 영향요인을 파악하기 위함이다. 이를 위해 본 연구에서는 2007-2011년간 청주에서 발생한 2천246건의 신호위반사고와 3천884건의 비신호위반사고 자료를 이용하여 두 집단 간의 차이를 검증하고자 한다. 주요 연구결과는 다음과 같다. 첫째, 신호위반사고는 야간시간대 및 직진상태에서 많이 발생하였다. 둘째, 신호위반사고와 비신호위반사고에 영향을 주는 변수로는 충돌형태, 충돌전 진행방향, 운전자 연령대(30대, 50대), 음주운전 및 사고유형 등으로 나타났다. 마지막으로, 이항 로지스틱 회귀분석에 의해 통계적으로 유의한 모형식이 개발되었다(Hosmer and Lemeshow test: 7.052, p-value:0.531).
