Abstract

This study investigated basic data on walking characteristics, including walking speed and cognitive-response for the elderly, and based on these, the time of walking signal was calculated. The on-site survey examined the actual pedestrian crossing speed using a stopwatch, and the age was divided into groups of ordinary people and the elderly. Analysis of the data showed that the average walking speed for the general public was 1.29 m/s, while the average walking speed for the elderly was 1.13 m/s, higher than that of the general public. In addition, the lower speed of the 15th percentile was analyzed to 1.01 m/s for the general population and 0.85 m/s for the elderly, showing a lower walking speed than the standard for the general area and 0.8 m/s for the protected area. However, for senior citizens who use walking sticks or wheelchairs, the speed of the lower 15th-percentile is 0.73 m/s, which is lower than the current standard of protected areas, according to the analysis.

본 연구는 고령자에 대한 보행속도 및 인지-반응을 포함한 보행특성에 관한 기초자료를 조사하였으며, 이를 토대로 보행 신호시간을 산정하였다. 현장조사는 스탑워치를 이용하여 보행자의 실제 횡단시간을 조사하였고, 구두조사로 연령을 조사하여 일반인과 고령자그룹으로 구분하였다. 자료를 분석한 결과 일반인의 평균보행속도는 1.29m/s, 노인은 1.13m/s로 일반지역의 기준인 1.0m/s 보다 높게 나타났다. 또한 하위 15th percentile속도를 살펴보면 일반인은 1.01m/s, 노인은 0.85m/s로 분석되어 노인의 경우 일반지역 기준보다 낮은 보행속도를 가지며 보호구역 기준인 0.8m/s 보다는 높은 속도가 나타났다. 하지만 지팡이나 휠체어를 사용하는 노인의 경우 하위 15th percentile속도가 0.73m/s로 나타나 현재 보호구역 기준보다 낮은 보행속도를 가진 것으로 분석되었다. 본 연구결과는 향후 노인의 보행환경을 개선하는데 적용할 수 있고, 장기적으로는 교통약자의 이동성 증진에 기여할 것으로 판단된다.
