Study On Data Integration For Mullti-Modal Route Navigation System Based On Web Service

As its name implies, the multi-model navigation system not only provide user the traditional car navigation but also the foot navigation, and the information of transfer among car navigation and public transport navigation and foot navigation, so multiple and real-time information from various sources in the system are needed, for example, real-time public transport information and real-time traffic flow and the accident information, real-time weather and parking lots information etc. With the development of Web service, it give multi-modal navigation system a good solution, we can get the multiple static and dynamic information from different web services such as public transport web service and real-time parking lots web service etc. In this paper we present a Multi-modal Route Navigation System for mobile user or web user. First we discuss the overall architecture of this system, and then we use the web service to get the static data and real-time information from different providers and integrate them based on XML (Extensible Markup Language) mechanism, and give a case study to describe how use the XSLT (extensible style sheet language transformation) engine transforms XML files from different sources into a union requirement XML format for multi-modal navigation system. In addition we discuss the current development and the application of web service from commercial and no-commercial web sites and give conclusion and future work.
