Abstract

Recently, due to THE MOBILITY ENHANCEMENT FOR THE MOBILITY IMPAIRED ACT, local governments have tired to make various efforts on special transport services(STS), low-flow bus, and installing elevator in subway stations for handicapped people. But in case of STS, insufficient numbers of taxi are raised against the increasing demand of hadicapped people due to the limited budget. This study investigated actual use condition of STS and characteristics of selection of handicapped people on Duribal. In addition, an ordered-logistic model was employed for developing taxi use prediction model considering taxi fare discounts for diverting Duribal demands to taxies. The results can be a significant basic data for transportation policies to improve travel efficiency of the handicapped.

'교통약자의 이동편의 증진법'이 제정됨에 따라, 각 지자체에서는 교통약자의 이동권을 보장하기 위해 지하철 역사 엘리베이터 설치, 저상버스 공급, 특별교통수단 도입 등의 다양한 노력을 해오고 있다. 그러나, 특별교통수단의 경우 예산의 제약으로 인하여 늘어나는 장애인 교통수요에 대비한 차량의 증차가 미흡한 상태이다. 따라서 본 연구에서는 부산광역시 특별교통수단 '두리발'을 대상으로 특별교통수단 이용실태 및 장애인의 교통수단 선택특성을 고찰하였다. 또한, 일반택시의 요금할인을 통하여 특별교통수단을 이용하는 장애인의 교통수요 분산을 유도하고자, 순서형 로지스틱 모형을 이용하여 요금할인에 따른 일반택시 이용 예측모형을 구축하였다. 본 연구의 결과는 특별교통 수단을 이용하는 교통약자의 이동효율 증진을 촉진할 수 있는 정책의 기초 자료로 사용될 것으로 기대한다.
