Abstract

As of 2020, 1,564 roundabouts have been installed and operated to prevent major traffic accidents and promote safe and smooth passage over the past 10 years. According to the Korea Transportation Research Institute, the number of accidents decreased by an average of 43.8% per year, fatal accidents by 50%, and serious injuries by 48.1%, confirming the safety effect. However, most intersections with high pedestrian traffic, such as children's protection areas near elementary schools, operate signal intersections. Therefore, in this study, a simulation was performed through the VISSM program to conduct a study on the pedestrian-centered roundabout installation method. This study was conducted to ensure that pedestrians can have the right of way safely by installing and operating traffic lights at crosswalks on roundabouts located in urban areas or child protection zones.

회전교차로는 지난 10년동안 대형 교통사고 예방과 안전하고 원활한 통행을 도모하기 위하여 2020년 기준 1,564개소가 설치되어 운영되고 있으며 한국교통연구원에 의하면 사고건수는 연평균 43.8% 감소하고 사망사고가 50%, 중상사고가 48.1% 감소한 것으로 나타나 안전성에 관한 효과가 검증되고 있다. 그러나 초등학교 부근 등의 어린이보호구역과 같은 보행량이 많은 교차로는 대부분 신호교차로를 운영하고 있으며 회전교차로가 설치된 경우 보행자들의 안전성 확보가 취약한 실정으로 이에 대한 개선이 필요하다. 이에 본 연구에서는 보행자 중심의 회전교차로 설치방안에 대해 연구를 수행하기 위하여 VISSIM 프로그램을 통해 시뮬레이션을 수행하였으며 분석된 주요 결과는 회전교차로 교통량이 적정할 경우 도시부나 어린이보호구역에 위치한 회전교차로 횡단보도에 신호등을 설치하여 운영할 수 있고 보행자들의 통행 우선권 확보가 가능하며 이로 인해 안전한 통행을 도모할 수 있는 것으로 연구되었다.
