Abstract

In Korea, older pedestrian accounted for 57% of all pedestrian deaths although a ratio of older pedestrian accidents to total pedestrian accidents was only 25.9%. Though ageing population problem becomes more challenging for road safety, little is know about the behaviour of older pedestrian's behaviour. This study aimed to identify road crossing behaviour of older pedestrian at three-lane unsignalized crosswalks using video image analysis and to compare the behaviour of older pedestrian to younger one by indicators including approaching speed, the number of walking steps and other factors. The results showed that there was a difference of approaching time at kerb, waiting time at kerb, the number of glances at kerb, and the number of glances at crossing between two groups under the situation of car approaching to crosswalks. It also showed that older pedestrian usually spent 1.16 times more than younger pedestrian to walk across the crosswalk with only 84.4% of walking speed of younger pedestrian. The number of steps of older pedestrian for road crossing was 1.12 times higher with 90% shorter steps than younger pedestrian. It was concluded that older pedestrian usually decided to walk across in case of 1.67 times longer headway than younger pedestrian's decision. These results could be applied in road and facility design for better safety of older pedestrians.

현재 우리나라 고령자의 보행사고건수는 전체 보행자 사고건수의 25.9%를 차지하고 있고 이중 고령자 사망사고는 57%에 달한다. 향후 다가올 고령사회를 대비하여 이러한 고령자 사고를 줄이기 위한 다양한 노력이 필요하다. 본 연구는 3차로 무신호 일반로 구간내 횡단보도지역에서 고령자와 비고령자의 횡단단계에 대한 이동행태지표를 정의, 조사 및 분석한 연구이다. 유의성 분석 결과, 고령자와 비고령자의 이동 행태상 몇 가지의 결과를 얻을 수 있었다. 첫째, 접근차량의 존재유무에 따라 고령자와 비고령자 간에 횡단보도 접근시간, 횡단보도 대기시간, 횡단보도 연석에서의 시선수, 횡단하면서의 시선수애 대한 통계적 차이가 존재하였다. 둘째, 횡단 보도 횡단시간의 경우 고령자는 비고령자의 1.16배가더 소요되고, 고령자의 보행속도는 비고령자의 84.4%의 수준이다. 셋째, 보행수는 고령자가 비고령자에 비하여 약 1.12배가 많았고, 보폭의 크기는 고령자가 비고령자에 비하여 90%의 수준을 갖는 것으로 확인되었다. 넷째, 고령자는 횡단을 위해 대기하는 동안 연속된 차량의 차두간격이 비고령자 대비 1.67배 이상 크게 요구하고 있었다. 이러한 주요 분석 결과는 고령자 횡단 시설 및 도로설계 등에 기초적인 자료로서 활용이 가능할 것으로 기대된다.
