| Abstract: | Starting with introducing the present situation of the worsening urban traffic and the rapid development of 3S technologies,this paper formulates the definition of the spatio-temporal GIS,space- time path,four kinds of spatio-temporal relations of human activities,and the setting up of the systematic model of the coordinate.According to the principle and model of GPS spatial positioning and navigation,this paper makes the optimized integration of the spatio-temporal GIS and GPS,and elaborates its functions such as the collection,analysis and presentation of the urban traffic information.The role of the spatio-temoral GIS and GPS integration in controlling the urban traffic such as early warning, warning,coordination etc.is discussed in the last part of the paper. |
