Abstract

Transportation planners consider travel as derived demand to execute various activities at destinations. Here what is important is ‘activity’. Travel is just a necessary act to perform the activity. Thus travel time is considered an opportunity cost, a time that is wasted. In that respect, the ultimate objective of building a new transport infrastructure is to shorten travel time. However, since everybody owns and uses smart phones these days, whether travelers can find some utilities while doing a range of activities during travel (such as reading news, watching dramas and listening to music) is controversial. In particular, if there are people who study or work during commuting, it means that commuting time can be productively used. That goes against the traditional assumption in transportation field that travel time is an opportunity cost. This study predicts monetary values of activities during commuting. Using the Contingent Valuation Method (CVM), the authors asked 1,000 residents of Seoul as to what they did while traveling to work and how much they would pay to continue their activities during commuting. Our analysis predicts that drivers, subway users and bus riders are willing to pay for 9,278, 7,963 and 5,475 Won/hour·month, respectively. For instance, a person who commutes for 2 hours every day using subway would be willing to pay for 16,000 Won a month. This result provides a useful information and insight to evaluate current transportation policies.

교통계획 분야에서는 통행을 목적지에서의 활동을 수행하기 위해 발생하는 ‘파생수요’로 간주한다. 이러한 관점에서 통행시간은 기회비용으로 이해된다. 따라서 새로운 교통 인프라를 구축할 때의 주된 목표는 시민들의 통행시간을 단축하는 것이다. 물론 통행시간은 단축되는 것이 바람직하지만 통행시간이 단순히 기회비용이라는 가정에는 의문이 제기될 수 있다. 이를테면 통행자들은 대중교통이나 승용차로 이동 중에 뉴스 읽기, 드라마 시청, 음악 감상은 물론 공부나 업무까지 다양한 활동을 수행하고 있다. 이 연구는 통근 및 등하교 통행을 대상으로 통행 중 활동의 금전적 가치를 추정하였다. 조건부가치측정법(CVM)을 활용하여 서울 거주자 1,000명을 대상으로 출근길에 어떤 활동을 하는지, 그리고 이동 중 수행하는 다양한 활동에 얼마를 지불할 의향이 있는지 조사했다. 분석 결과, 1시간 통행 중 활동에 운전자는 매월 9,278원, 지하철 이용자는 7,963원, 버스 이용자는 5,475원을 지불할 의향이 있는 것으로 나타났다. 이 연구의 결과는통행 중 활동의 금전적 가치를 추정하여 통행시간 개념에 관한 새로운 시각을 제공한다. 본 연구 결과를 바탕으로 후속연구에서는 자율주행 차량 등에 관한 심도있는 논의가 가능할 것이라 기대한다.
