Visual Modeling and Representations of Spatiotemporal Transportation Data: An Object-Oriented Approach

Information technologies are widely applied to present the investigation and exploration of the modeling approaches involving spatial, temporal and spatio temporal data in a geography information system (GIS) framework. This paper introduces a visual object-oriented modeling approach which is applied to the modeling and representations of spatio temporal transportation data, and is supported by the unified modeling language (UML). The modeling process implements the adaption, integration and extensions of spatial and temporal UML-based semantics based on the plug-in for visual languages (PVLs) for accommodating the descriptions of dynamic transportation system. The study presented in this paper implements the representations and maintains of the multiple properties, relationships and behavioral changes of transportation data. This promotes the cognition of the complex process of transportation objects, activities and phenomena, particularly the visual modeling and representations of spatio temporal transportation data in the context of a dynamic transportation system. Also, it offers a media to enhance means of communication between model designers and transportation professionals.
