Abstract

Changes in the life style might vary trip purposes, ultimately leading to the change in the travel behavior. Therefore, this study analyzed the factors affecting travel time change by using the time use survey data in Seoul, surveyed by the Statistics Korea in 1999~2014. We developed multiple linear regression models for travel time, considering individual, household and time-related variables as independent variables. The models were separately estimated weekday and weekend. the model results show that the household, individual, and time related variables have an significant effect on the travel time. In addition, travel time is more influenced by individual characteristics thn household ones. Each activity time positively affects the travel time, indicating that travel is derived demand. The variable that have the greatest influence on the travel time is the activity time for leisure.

생활패턴의 변화는 통행의 목적을 변화시키기 때문에 궁극적으로 통행패턴의 변화를 야기한다. 이에 따라 본 연구에서는 1999년부터 2014년까지 통계청에서 조사한 생활시간조사자료를 활용하여 연도별 통행시간에 영향을 미치는 요인을 분석하고자 한다. 가구관련, 개인관련, 시간관련 변수들을 고려한 통행시간에 관한 다중선형회귀모형을 구축하였으며, 요일별 차이를 보기위해 주중과 주말을 분리하여 추정하였다. 모형 추정 결과, 가구관련, 개인관련, 시간관련 변수가 통행시간에 영향을 미치는 것으로 분석되었다. 가구관련변수의 경우 개인관련변수에 비해 비교적 적은 변수들이 유의한 것으로 나타났는데, 이는 통행이 개인특성에 더 큰 영향을 받기 때문인 것으로 판단된다. 각 활동시간들은 통행시간에 양의 영향을 미치는 것으로 분석되어 통행이 파생수요임을 나타내고 있다. 또한 여가활동시간이 가장 큰 영향력이 있는 것으로 도출되어, 여가를 위한 통행시간이 타활동에 비해 증가하는 것으로 분석되었다.
