Abstract

This study deals with the relationships between signal operation and traffic accident of signalized intersections. The objective of this study is to analyze the traffic accident reduction effects on the operation of all-red clearance interval (ARCI). This study gives particular attentions to evaluating the traffic accident reduction effects of ARCI at 37 signalized intersections in Cheongju using before-after evaluation with comparison group. The main results are as follows. First, the number of traffic accidents, fatalities and injuries has changed before operating ARCI and thereafter. Second, the result of before-and-after evaluation with comparison group showed that the number of accidents was reduced by 20.0% and that the number of fatalities and injuries was reduced by 28.0%. Finally, reduction effects from operating ARCI were evaluated to be 6.0~35.0% in the number of accidents and 18.0~37.0% in the number of fatalities and injuries.

이 연구는 신호교차로의 신호운영과 교통사고의 관계를 다루고 있다. 연구의 목적은 전적색신호시간(ARCI) 운영에 따른 교통사고 감소효과를 분석하는데 있다. 이를 위해 이 연구는 청주시 37개 신호교차로를 대상으로 비교그룹 방법을 사용하여 ARCI의 교통사고 감소효과를 평가하는데 중점을 두고 있다. 주요 결과는 다음과 같다. 첫째, 교통사고 건수와 사상자 수는 ARCI 도입 전 후가 다른 것으로 평가되었다. 둘째, 교통사고 감소효과를 비교그룹방법으로 분석한 결과, 사고건수는 20.0%, 그리고 사상자 수는 28.0% 감소한 것으로 분석되었다. 마지막으로, 전적색신호시간 운영에 따른 사고건수의 감소 효과는 6.0~35.0%, 사상자 수의 감소 효과는 18.0~37.0%로 평가되었다.
