Abstract

This study presents a methodology that can integrate the information generated by the Busan taxi DTGs and Tachometers. Utilizing the results by the methodology, travel patterns of taxi users were analyzed. Also to verify the reliability of the methodology was conducted by comparing its results with those of O-D information of the National Transportation DB (KTDB). Despite the limited number of samples. the results of this study showed that DTG data, which can reflect changes in status and conditions in real time, can be used as a replacement for KTDB. It is expected that the results generated by the suggested methodology can be useful for developing and executing desirable taxi related policies.

본 연구의 목적은 부산시 택시 운행기록계(DTG)와 타코메터에 의해 생성되는 개별 정보의 통합 방법론을 제시함에 있다. 통합방법론에 의해 도출된 정보를 활용하여 다양한 택시이용자 통행패턴을 분석하여 도출정보 활용성을 검토하였다. 또한 제시 방법론에 의한 O-D정보와 국가교통DB(KTDB)의 O-D정보와의 비교를 통해 방법론에 대한 신뢰성 검증을 시도하였으며, 제한된 표본 수에도 불구하고 상당히 유사한 결과를 나타냄을 알 수 있었다. 본 연구 결과는 현황 및 여건변화를 실시간 반영 가능한 DTG 자료가 향후 KTDB의 대체자료로 활용 가능함을 보였으며, 또한 국가 주도의 택시 정보플랫폼 구축시 매우 유용한 기초 연구로서, 또한 택시 정책 수립과 집행에 기초자료를 제공할 수 있을 것으로 기대한다.
