This paper explores characteristic differences of pedestrian environments in six urban residential neighborhoods, Seoul, Korea. The cases range from the residential neighborhood of single detached old houses to that of recently redeveloped high-rise apartments, which represent different types of residential neighborhood forms in Seoul. The selected cases are Gahoe-dong, Sanggye7-dong, Shiheung3-dong, Hangdang2-dong, Gaepo3-dong, and Sungsan1-dong. The goal of this paper is to test whether the walkability indicators, proposed in the previous paper, operate well in demonstrating the differences of each neighborhood's walking conditions. The research methods include literature reviews of existing studies, GIS analyses, and site observations on walking and neighborhood forms. The research findings point that the proposed walkability indicators positively work in revealing each case's different walking environment. According to the findings, among the six case neighborhoods, Sanggye7-dong provides most walkable neighborhood characteristics, while Hangdang2-dong does least. The contribution of this research is that it tested the walkbility indicators representing the environmental characteristics of physical walking conditions in residential neighborhoods of Korea for the first time. Modified by further studies, those indicators would be useful in evaluating and then designing more walkable residential neighborhoods in Korea.
