부산광역시 교통카드데이터를 활용한 버스 내 재차인원 추정 및 혼잡도 표출

Abstract

The objective of this paper is to calculate passenger occupancy and the degree of congestion in a Busan City bus using the data collected from transit cards. Most of the local governments have adopted the Bus Information System (BIS) for their users. The service provides real-time bus location-based information through Bus Information Terminals (BIT) to improve user convenience. However, additional information beyond bus arrival time is required for choosing the most efficient traffic means and enhancing service. Therefore, we calculate passenger bus occupancy using the passenger number data classified by station. The model for estimating bus occupancy reflect distinct characteristics in the Busan bus card system which do not require an additional scan of their transit card when passengers exit the bus. Finally, depending on the congestion of estimated passenger bus occupancy, we classified level of service into three categories based on passenger numbers. Accuracy of estimated results is more than 80%. And if punctuality of buses is improved, the accuracy of the study will be advanced. The proposed system in this study provides advantages of efficient decision-making and more convenient bus use.
