EVALUATION OF PUBLIC TRANSPORTATION LEVEL OF SERVICE USING THE MINIMUM-COST HYPERPATH SEARCH ALGORITHM

Abstract

 In urban rail systems worldwide, inadequate nodal functions—such as inter-station passageways and station plazas—are frequently observed, and problems with transfer convenience to other lines and transport modes have become apparent. This situation partly reflects a history in which station locations were determined without sufficient consideration of surrounding development plans and site suitability. Quantitative evaluation of level of service at the planning stage can raise planners’ awareness of the importance of nodal functions, encourage project designs that account for transfer convenience, and help minimize the social costs associated with future retrofits of connectivity nodes. In this study, we extend the Hyperpath model by incorporating fare and transfer-resistance components to construct a multimodal level-of-service indicator that more closely reflects users’ perceived convenience. A case study of the Kama-Kama Line development project quantitatively assesses the convenience experienced by Haneda Airport users at each implementation phase.
