서울시민의 저상버스 이용 지불의사액에 미치는 영향 요인 분석: 이중허들모형의 활용

초록

The goal of this study is to estimate the willingness to pay for the additional introduction of low-floor bus in Seoul at the level of developed countries and to identify the factors affecting the willingness to pay and the level of payment, thereby providing quantitative basic data necessary for the low-floor bus policy. To derive the willingness to pay, we utilized the contingent valuation method (CVM) and survey data from 1,473 Seoul citizens aged 20 or older, including 289 elderly respondents aged 65 or older. For the analysis, we divided the willingness to pay and the level of payment into two stages and used the double-hurdle negative binomial model to handle data overdispersion. Sixty-seven percent of respondents expressed a willingness to pay, and the average stated amount was about KRW 171.36. As a result, age, health condition, support for mobility handicapped policy, and monthly city bus fare expenditure significantly influenced willingness to pay, while age, household income, and experience using low-floor buses significantly affected the level of payment, confirming that willingness to pay and the level of payment were affected by different factors. This study is expected to make a practical contribution by providing quantitative policy data necessary for the additional introduction of low-floor buses to enhance mobility for the transportation disadvantaged.
