Research on Temporal and Spatial Data Models Based on GIS for Urban Traffic Planning Information Support System

Based on the analysis of spatial and temporal characteristics about urban transportation planning information, this paper discussed the method about introducing the time dimension during build object-oriented spatio-temporal data model in urban transportation planning system, built the relations of history topology in space, Studied on the information storage and management of space information such as the geometry and topology of the data object in urban transport planning information system, which laid the foundation for the realization of the spatio-temporal information management of the urban transportation plan.
