Abstract

As pedestrian deaths account for a high proportion of traffic accident deaths in Korea, interest in pedestrian safety is growing. In particular, it is necessary to develop various pedestrian-centered traffic signal operation techniques to improve the pedestrian environment at signal intersections. Therefore, in this study, a method for time-of-day operating a pedestrian signal based on residual pedestrians was studied. To this end, the pedestrian signal operation technique in response to the pedestrian demand, which is operated by extending the pedestrian signal time only during the time when the pedestrian demand and the number of remaining pedestrians increase, was applied to the field. The difference in safety according to the application of the new pedestrian signal operation technique was statistically analyzed. As a result of the analysis, the residual pedestrian rate decreased by 20% (3.3 people) before application and 8% (1.4 people) after application, and the residual pedestrian rate in the crosswalk at the time of red signal decreased by 12% (1.9 people), And it was analyzed that the position of the residual pedestrian decreased by 3.3m from 5.2m before application to 1.9m after application.

우리나라 교통사고 사망자 중 보행 중 사망자가 높은 비율을 차지하고 있으며, 정책적으로 보행안전에 대한 관심이 높아지고 있다. 특히, 보행자 교통사고가 많이 발생하는 신호교차로에서 보행환경 개선을 위하여 다양한 보행자 중심의 교통신호 운영기법 개발이 필요한 시점이다. 이에 본 연구에서는 잔류보행 기반 시간대별 보행신호 운영기법을 연구하였다. 본 연구에서는 보행수요와 잔류보행자가 증가하는 시간대에 한해서 보행신호시간을 더 늘려서 운영하는 잔류보행기반 시간대별 보행신호 운영기법을 현장에 적용하였으며, 제안한 보행신호 운영기법 적용에 따른 안전성의 차이를 통계적으로 분석하였다. 분석 결과, 현시 단위 잔류보행자율은 적용 전 20%(3.3명), 적용 후 8%(1.4명)으로 감소하였으며, 적색신호 시 횡단보도 내 잔류하는 잔류보행자율이 12%(1.9명) 감소하고, 그리고 잔류보행자의 위치는 적용 전 5.2m에서 적용 후 1.9m로 3.3m 감소하는 것으로 분석되었다.
