Abstract

This study analyzes 'willingness to have passenger cars' through perception survey about car use and possession. Social problems caused by increasing car use are serious. Because of the fact that 78.9% of registered vehicles are passenger cars and 75.3% of passenger cars are private cars, passenger cars are main reason of Social problems caused by using a car. So, we need to analyze the reason why people possess cars and need additional cars. Also we need to study about 'willingness to possess additional cars' through analysis of perception about car use and ownership. According to survey results, most households possess cars as means of commute, and most households need additional cars as means of commute to office, leisure, kids' commute to school and academy. Also we used Structural Equation Model to analyze car use and 'willingness to possess additional cars' according to ownership. Analysis results showed that car use is positively impacted by driving and usage perception, and negatively impacted by social problems such as parking, traffic congestion, traffic environment, and etc. Also, results showed that the number of car is positively impacted by usage perception, and negatively impacted by expenses. In case of 'willingness to have additional cars', is positively impacted by intention to use cars and negatively impacted by car ownerships. We think research results can be used as basic data to manage traffic demand.

본 연구는 승용차이용 및 보유의식 조사를 통하여 승용차 보유의향에 관한 분석을 다루고 있다. 증가하는 차량이용으로 인하여 발생하는 사회적인 문제는 심각한 상태이다. 차량등록대수의 78.9%는 승용차이고 그 중 자가용승용차는 75.3%로 승용차의 대부분을 차지하고 있으므로 차량 이용에 따라 발생하는 사회적인 문제의 주요 원인은 자가용승용차로 볼 수 있다. 이에 승용차 이용목적과 추가적인 보유목적에 대해 알아 볼 필요가 있다. 또한 승용차 이용의식과 현재 보유하고 있는 승용차대수를 분석하여 향후 추가적인 승용차 보유의향에 대해 연구 할 필요가 있다. 따라서 설문조사결과를 바탕으로 연구를 진행하였고 주요 결과는 다음과 같다. 현재 대부분의 가구에서는 출퇴근 및 통학용으로 승용차를 보유하고 있고 향후 추가적으로 보유하고자 하는 목적으로는 출퇴근 및 통학과 여가용, 자녀들의 학교 및 학원 통학용으로 나타났다. 구조방정식모형을 활용하여 승용차 이용 및 보유대수에 따른 승용차 보유의향에 대해 분석한 결과 승용차 이용은 운전인식과 이용인식에 정(+)으로, 주차, 교통 혼잡, 환경 등과 같은 사회적인 문제에 부(-)의 영향을 받고 승용차 보유대수는 이용인식에 정(+)으로, 비용적인 측면에서 부(-)의 영향을 받는 것으로 나타났다. 승용차 추가보유의향의 경우 승용차 이용의사에 정(+)으로, 현재 승용차 보유대수에 부(-)의 영향을 받는 것으로 나타났다. 본 연구결과는 향후 교통수요관리를 위한 기초적인 자료로 활용할 수 있을 것이라 판단된다.
