한국형 보행환경평가 모델 개발을 위한 기초 연구

Abstract

Walking has been neglected for a long time despite the fact that it is an important transportation mode. Recently, the Korean government initiated various pedestrian environment improvement projects to improve poor walkability conditions. However, it is difficult to evaluate quantitatively the effects of implementing those projects because of lack of evaluation system. In this context, this study conducted a preliminary study on the development of pedestrian environment evaluation model that can be used for Korean walking conditions. The study scope was limited to sidewalk segments (links) and intersections along the car streets. Nine intersection and eighteen link factors were suggested which were considered to be associated with pedestrian environmental quality and safety. While the intersectionrelated factors were grouped into two domains (safety and expediency), the link-related factors were grouped into three domains (safety, amenity, and connectivity). Based on the expert survey, weights were determined to each domain and its factors, and score values were also assigned to the factor response categories. This process enabled a specific link or intersection to be evaluated on a scale from 0 to 100. A case study was also carried out to demonstrate how to use the developed model. It is expected that the developed model would find many applications since it is helpful not only to determine the priority for links or intersections that deserve improvements, but also to evaluate quantitatively the degree of improvement of a specific pedestrian environment improvement project.
