초록

이 논문은 통행선택행위를 간접효용함수 대신 체감비용을 비교하는 평가방법을 제시하였다. 체감비용 비교방법은 가계생산이론을 통행자가 통행비용과 시간 등 정량적 요소와 함께 안락성과 안전성 등 정량적 요소를 동시에 고려하는 경우에 적용하여 도출되었다. 이 분석에서는 통행행위가 통행목적 달성과 함께 여러 정성적 요소를 동시에 산출하는 과정을 기술하는 특수한 형태의 동차 공동생산함수를 고안하여 이용하였다. 통행대안별 체감비용은 금전적인 통행비용에 시간가치 중에서 정량적 요소에 대해 통행자가 느끼는 기회비용을 제한 값을 합하여 산출하였다. 이러한 체감비용은 통계적 측정가능조건을 충족시킬뿐더러 통행선택행위를 보다 합리적으로 설명할 수 있어, 통행선택에 대한 통계분석에서 간접효용함수에 비해 통계측정 대상으로서 보다 우수하다.

This paper suggested an approach to characterize travel choice behaviors using the implicit price instead of the indirect utility. The choice criterion to compare the implicit prices of available trip options was developed from the utility maximization problem of a trip maker which is supposed to choose the best option from the available ones differentiated by only by the quantitative attributes such as travel cost and time but also by qualitative attributes such as comfort and safety. The utility maximization problem is constructed under household production theory, and is incorporated with a special kind of joint homogeneous production functions. The implicit price of a certain trip option is the sum of the monetary price and the multiple of travel time and the value-of-travel-time, and the value-of-travel-time refers to the portion of wage, which can be assignable to the trip-making activity. This choice criterion is statistically identifiable, and behaviorally plausible. Moreover, this criterion has the expression simpler than the indirect utility, and therefore could be an effective target of the statistical estimation for travel choice behaviors.
