A UML-Based Visual Modelling Tool Integrated with PVL for Urban Metro Transit Network Data Modelling——A Case Study of the City of Guangzhou, China
This paper proposes the design of a spatial-temporal Geographic Information System for Transportation (GIS-T) data model for facilitating analysis and management of an urban metro transit network (MTN). We apply a UML-based visual modelling tool integrated with spatial plug-in for visual languages (Spatial PVL) that supports spatial multi-representation abstractions of static and dynamic objects to facility analysis and conceptual spatial-temporal modelling without considerations of implementation issues. The approach provides a description of the formalism based on UML Class Model schemas, and the geospatial transit network structure with a special emphasis on spatial, temporal and spatial-temporal components provided by PVL extensions. On the basis of the stereotype extension mechanism of UML, the resulting metro transit network data model for the city of Guangzhou,China is specified as high-level conceptual class models using a UML-based object-oriented visual modelling language that is extended with the spatial and temporal PVLs pictograms.
