Fusion and Integration Framework Study on Road Network and Dynamic Traffic Data in Vehicle Navigation

The rapid fusion and integration of road network and dynamic traffic data is vital for real-time road vehicle navigation. Yet current navigation electronic map and geographical information systems (GIS) are not well adapted to the real-time dynamic traffic navigation data integration and integrated Spatio-temporal database manipulation. This paper brought forward the principles, methodologies, integrative road network and dynamic traffic data spatial-temporal data model architecture and prediction method of short-time traffic parameters, which will provide a reference foundation for a high efficient multi-scale, multi-modal new vehicle navigation and LBS system.
