Abstract:

Within the domain of Intelligent Transportation Systems (ITS) research, models devoted to solving dynamic traffic problems are proposed by means of integrating historical data with real time traffic information. Due to the complexity of these models and the strength of spatial analyzing and display capability of GIS, a trend of embedding these algorithms with GIS is emerging. Although GIS has been adopted in many disciplines to solve real world problems successfully, bottlenecks exist because 1) current GIS mainly deals with data that are not sensitive to temporal changes; 2) the need of decomposable data structure in GIS to facilitate processing algorithm to meet the time constraints of dynamic (real-time) routing system, and 3) the need of a consistent location referencing system to integrate spatial data from various sources. This paper discusses these difficulties in details and proposes a conceptual model by integrating GIS with dynamic traffic asignments algorithm(DTA) to resolve this problem.
