주택유형과 대중교통 접근성의 불균등 요인이 통행목적별 보행활동에 미치는 영향분석

Abstract

This study analyzed the inequality factors of housing type and transit accessibility that influence walking time and frequency for one-weekday travel. Using the 2010 household travel survey data for the residents in the city of Seoul, in particular, the study has focused on articulating moderation effects of housing type and transit accessibility with regard to personal and household characteristics in walking activity by purposes. This study employed two-level (personal and household levels) regression modeling with dependent variables such as daily walking time, fulfillment of recommended daily physical activity time, and walking frequencies by travel purposes (daily life and non-daily life). Based on each dependent variable's data distribution, this study utilized linear, tobit and poisson regression models. Analysis results demonstrated that housing type and transit accessibility interacting with personal and household characteristics affect individual walking activities. That is, walking time and frequency by travel purpose are moderated through interactions between housing type and household income as well as interaction between bus transit accessibility and rail one. We suggested policy implications for walking activity with respect to housing type and transit accessibility.
