고령자의 통행에 미치는 요인 분석: 수도권 사례 연구

Abstract

Recently rapid aging society has been a critical issue everywhere in Korea. In transportation field, however, travel behavior of the elderly has not much been considered in transportation planning and policy, thereby limiting their mobility and accessibility. This study is to identify key factors influencing travel behavior of the elderly using 2006 household travel survey data in Seoul Metropolitan Area. To this end, we first conducted descriptive analysis on travel characteristics between elderly (65 years or older) and non-elderly (19 ~ 64 years) groups with respect to trip frequencies, trip purpose, mode, trip distance, and travel time. Then, we developed ordered probit models for number of trips, and log-linear models for travel distance and time by total and travel purpose (work and shopping/social/personal business), considering household and personal characteristics, and land use variables as explanatory variables, and compared the model results between two groups. The results show that economic and socio-demograhic variables (such as gender, age, household size, and income) and land use (such as population and employment density) variables significantly affect elderly travel.
