Paper Abstract

Due to the phenomenon of route overlapping, issues with bus transit have never been easily handled. For transit models and transit trip guidance, accurate quantitative data have to be retrieved from transit database. The appropriate representation of bus transit entities is of key importance in these tasks. The simple route-stop bus data model is efficient at the macro level and has been applied in many transport-related applications. However, a more comprehensive data model is needed to cope with different levels of needs as well as complicated situations existing in heavily bus-oriented cities. A multi-tier, object-oriented bus data model is developed in response to these requirements. The multi-tier data model puts transit features under one unified framework, which facilitates multi-scale applications of bus transit system.
