Abstract

This study analyzes factors that affect average daily travel time budgets, using the Time Use Survey data from 1999 to 2014 in Seoul. We first developed multivariate regression models for travel time from each year, considering demographic and socio-economic variables as well as non-home activity time. The model results showed that household and personal characteristics and non-home activities significantly affect travel time, and their effects are different over time. In addition, we developed seemingly unrelated regression (SUR) models for time allocation for non-home activity and travel, considering their correlations, and explanatory variables were compared over time. Overall, demographic and socio-economic variables significantly affect travel time as well as non-home activity time.

본 연구에서는 1999년부터 2014년까지 통계청에서 조사한 생활시간조사 자료를 활용하여 조사연도별로 평일 통행시간예산에 영향을 미치는 요인을 분석하여 이를 비교하고자 하였다. 먼저 인구 및 인구 및 사회경제지표, 비가정 활동시간 등을 비가정 활동시간 등을 고려한 통행시간에 관한 다중회귀모형을 구축하여 영향력을 분석하였다. 모형추정 결과, 가구특성, 개인특성, 비가정 활동시간 변수들이 통행시간에 유의하게 영향을 미치는 것으로 분석되었으며, 연도별로 영향력에 차이가 있음을 확인하였다. 또한, 통행시간과 비가정 활동시간간의 상관성을 고려하여 SUR모형을 구축하였으며, 독립변수들이 미치는 영향력을 시계열적으로 비교·분석하였다. 전반적으로 인구 및 사회경제지표가 통행시간은 물론 비가정 활동시간들에 지속적으로 영향을 미치고 있는 것으로 나타났다.
