Abstract

The expressway facilities management system is becoming crucial for successful traffic management with the spreading of expressway construction in China. In this paper, the current expressway facilities management systems are analyzed. Due to lack of the spatiotemporal data management capability of these systems, a bi-temporal spatial data model is proposed, which combines the temporal relational data structure with the spatial data model. In considering the characteristics of expressway facilities management, the corresponding data structure and data manipulation steps are formulated. Hopefully the research would make a useful exploration for the expressway facilities management transformation from three-dimension to spatiotemporal four-dimension.
