utis (urban transportation information system) a geo-spatial transport database
This paper proposes the design of an extended DBMS as required for integrated management of urban transportation systems. We introduce an extended `lowest common denominator' database model that supports a wide and varied range of urban transport tasks, which include management, simulation and planning. This paper is the result of research being carried out and is formulated by database expertise and transport knowledge. There has been a full analysis of transport data objects and attributes. The database schema is based on an object-relationship model extended to the representation of spatial data types and spatial and temporal events.
