Abstract

Passenger cars occupy about 74% among registered vehicles in Korea and the ratio of transportation mode sharing is approximately 60% in the passenger transport part. However, there is no statistics related to travel characteristics of passenger cars, and official statistics are estimated from O/D travel data. Thus, National Transportation DataBase Center in KOTI has attempted to construct various statistical data through Korea Vehicle Use Survey. Based on these data, Analysis of Variance (ANOVA) was conducted to investigate the differences in travel characteristics of each analysis group. As a result, all of the explanatory variables(weekday vs. weekend, metropolitan area vs. non-metropolitan area, male vs. female, commute time vs. other time, routine purpose vs. non-routine purpose) were found to be different across households. In addition, travel distances per trip of weekday, metropolitan area, male, commute time, and non-routine purpose are longer than the opposite variables. Also, the trip distances of small size(1 to 2 persons) households are shorter compared to large size(more than 5 persons) households.

우리나라에서 자가용 승용차는 전체등록차량의 약 74%의 정도를 차지하고 있고, 여객수송부문에서 차지하는 수단 분담비율도 약 60%(도보, 자전거, 기타 제외) 정도를 차지하는 주요 교통수단이다. 하지만, 자가용 승용차관련 보유 및 이용 관련한 통계는 전무한 상태일 뿐만 아니라, 분담율 산정의 기준이 되는 인-km 수송실적 자료조차 여객기종점통행량을 기초로 추정한 값을 사용하고 있다. 이에 한국교통연구원 국가교통DB센터는 '자가용이용실태조사'를 통해 자가용 승용차의 이용 및 보유관련 다양한 통계자료를 구축하고자 하였으며, 본 연구에서는 '자가용이용실태조사'를 통해 구축된 통행자료 기반으로 가구인별 통행특성 차이를 분석하기 위해 ANOVA(Analysis of Variance)를 실시하였다. 분석 결과, 가구 규모별로 모든 설명요인(주중 vs. 주말, 수도권 vs. 비수도권, 남성 vs. 여성, 출퇴근 시간 vs. 기타시간, 일상 vs. 비일상)간 차이가 있는 것으로 분석되었으며, 주말보다 주중이, 비수도권보다 수도권에서, 여성보다 남성이, 출퇴근 시간이 기타시간보다, 비일상 통행보다 일상통행의 경우 통행당 거리가 길게 나타났다. 특히, 소인가구의 통행당 거리가 다인가구에 비해 상대적으로 짧게 나타나고 있음을 알 수 있었다.
