교통약자 이동지원 서비스의 사회적 가치 추정 연구: 장애인콜택시의 통행시간 질적 수준 개선을 중심으로

Abstract

Since the enactment of the Act for the Promotion of Convenience in the Mobility of Vulnerable Populations, the central government and local authorities have been taking the lead in implementing projects to improve and expand transportation means, passenger facilities, and pedestrian environments for people with disabilities and the elderly. However, the inconvenience in mobility for vulnerable populations remains a serious issue. While multifaceted efforts are being made to secure the mobility rights of vulnerable populations, research on the effectiveness of service expansion and its societal value is not actively conducted. Most domestic mobility support services for vulnerable populations are primarily funded and driven by local governments or public agencies, making it challenging to expand services due to issues related to funding and operational efficiency. To activate services with high societal value, there is a need for national consensus on service operation, which can lead to sustainable funding and operations. This study aims to estimate the qualitative improvement effect of travel time, one of the societal values associated with mobility support services for vulnerable populations. It analyzes the factors influencing this effect by utilizing Contingent Valuation Method (CVM) to estimate the Willingness to Pay (WTP) of users of disability call taxis residing in Seoul, South Korea. The survey includes general information about the survey participants and open-ended questions related to their use of disability call taxis, as well as an analysis of the factors affecting WTP.
