  • 옐로카펫 보급된 이후 어린이 교통사고는 감소세이나 아직 옐로카펫 설치와 교통사고간의 인과관계에 대한 설명력은 부족한 상황이다. 기존의 실차조사연구에서 상황 구현의 어려움이나 위험성 등의 이유로 수행하지 못한 다양한 상황을 VR시뮬레이션 실험을 활용하여 옐로카펫 효과를 더욱 심도있게 분석하였다. 실제 옐로카펫이 설치되어있는 대상지를 선정하고, 가상환경으로 구현한 후 시선측정장비를 착용하고 시뮬레이터에 탑승하도록 하였다. 옐로카펫 설치 전·후의 시각/주행행태를 비교하였고, 통계적 검증을 위해 t-test 분석을 수행, 모두 통계적으로 유의한 수준인 것으로 나타났다.

  • Pedestrian safety was recently highlighted with a yellow carpet, a yellow-colored pavement material prepared for children waiting for signals for pedestrian crossing, without validation of its efficiency in practice. It was a promising device likely to assist highway safety by stimulating pedestrian to step on the yellow-colored area; it was generally called nudge effects. This paper delivers a study conducted to check the effectiveness of yellow carpet in three different aspects in vehicle driver's perspective by applying the newly introduced information technology (IT) service: Visual Attention Software (VAS). It was assumed that VAS developed by 3M in the United States should be able explain the Korean drivers' visual reaction behaviors since technology embedded in VAS was developed based on and proved by other various international countries and continents in the world. A set of pictures was taken at thirteen different field sites in seven school zone areas in the Seoul metropolitan area before and after the installation of a yellow carpet, respectively. Sets of those pictures were analyzed with VAS, and the results were compared based on the selective safety measures: the likely focusing on standing pedestrians (waiting for a pedestrian's green signal time) affected by its background (yellow-colored pavement) contrasting him or her. The test results from a set of before-and-after comparison analyses showed that the placement of yellow carpet would (1) increase 71% of driver's visual attention on pedestrian crossing areas and (2) change the sequential order of visual attention on that area 2.4 steps ahead. The findings would enhance deployment of such promising efficiency and thus increase children safety in pedestrian crossing. The result was promising to highlight the way to support the changes in conservative traffic safety engineering field by applying the advanced IT services, while much robust research was recommended to overcome the limitation of simplification of this study.
