Abstract

This study attempts to construct a model of optimal headway, focusing on a practical applicability to bus transit operation. Examining the existing bus operation and scheduling plans imposed by Busan City, we found that the plans failed to reasonably take into account such realities as varying traffic and operational conditions. The model is thus developed to derive the hourly optimal headway by routes satisfying the real-world conditions: varying hourly demand and cycle time, applying the model to routes 10 and 27 as examples. To do so, we collect big-dataset generated by smart card system and BIMS (Bus Inforamtion Management System). It is expected that the results of this study wil be a basis for further refined research in this field as well as for preparing practical timetables for bus operation.

본 연구는 현실 적용성을 고려한 버스 최적 배차간격 모형 구축을 통해 현실적 운행계획 작성에 기여하고자 한다. 부산시가 제시한 시내버스 운행계획의 적정성 검토를 통해, 배차간격 및 운행시간이 현실적 여건을 고려하지 않고 계획되어 있음을 파악하였다. 이에 실제 도로 여건과 운행환경을 고려한 운행시간 제약조건과 해당 노선의 수요 충족을 위한 시간대별 배차간격 도출 모형을 구축하였고 부산시 10번과 27번 노선을 사례로 모형의 적용성을 검증하였다. 본 연구는 교통카드 및 BIMS (Bus Information Management System)가 제공하는 방대한 자료(Big-Data)로부터 필요 정보를 추출하였으며, 그 과정에서 분석에 필요한 자료와 정보 추출 과정도 요약 제시하였다. 본 연구의 결과는 현실적 운행계획 작성과 향후 보다 정밀한 여건을 고려한 연구에 기여할 것으로 기대한다.
