Abstract

This study aims to propose the location selection method of car-sharing services in Daejeon Metropolitan city. In order to select locations for car-sharing, Daejoen area was divided in $500m{\times}500m$ cell size using GIS Arc/Info 10, and input factors which may affect car-sharing service were determined, and then each input factor was standardized for analysis. The weight for each input factor was determined through experts' survey and index of goodness of fit was estimated in each cell ($500m{\times}500m$ size) using AHP method. Also, This study proposed the method to select 30 service facility location using Location-allocation Model in Network Analysis module. The proposed method for the location selection of car-sharing service in this study can be used for preliminary data for initial car-sharing introduction. Henceforward, appropriate demand forecasting and economic evaluation for the location selection of car-sharing service are needed for the further study.

본 연구에서는 대전광역시를 대상으로 향후 카쉐어링 서비스를 제공할 경우를 가정하고 위치 선정방안을 제시하는 것을 목적으로 한다. 이를 위해 GIS Arc/Info 10 소프트웨어를 활용하여 대전광역시 전역을 $500m{\times}500m$ 크기의 셀로 구분하고 카쉐어링 서비스에 영향을 미칠 것으로 예상되는 요인들을 선정하고 각 요인들의 값을 표준화하는 과정을 거쳤다. AHP 기법을 도입하여 각 요인별 가중치를 전문가 설문을 통해 결정하고 모든 셀($500m{\times}500m$ 크기)별로 적합도 지수를 산정하였으며, 네트워크 분석(Network Analysis)모듈에 내장되어있는 입지배분모델(Location-allocation Model)을 이용하여 서비스 시설의 위치를 30개의 권역으로 선정하는 방안을 제시하였다. 본 연구에서 제안한 카쉐어링 서비스 위치선정을 위한 방안은 향후 카쉐어링 서비스가 도입될 때 기초 자료로 활용할 수 있을 것으로 기대되며, 향후 적정한 수요의 추정과 경제성 검토 등에 대한 추가연구가 필요할 것으로 판단된다.
