Multimodal Traffic Information Service System with K-Multimodal Shortest Path Algorithm

This paper focuses on extraction existing traffic information from heterogeneous traffic information systems and integration these information into urban traffic information platform (UITIP). And the relation of traffic data organization and multimodal network topological modal are constructed and integrated within geographic information system (GIS). Then as to provide personal preferences and contiguous on-trip/pre-trip information in multimodal transportation, a K-multimodal shortest path algorithm is design. Finally, multimodal on-trip/pre-trip information is provided to users through various means with open data exchange protocols.
