Architecture research on centrally dynamic route guidance system

Recently, many existing systems provide varieties of Route Guidance Services for different devices independently. It is difficult to provide all useful traffic information for one trip's departure to arrival. So integrating and reusing all of these systems becomes the research hotspot in the field of traffic information service. This paper proposes a strong architecture to integrate these multiple systems refer to the concept of Service-Oriented Architecture. This approach is not only useful to construct a uniform platform to provide all kinds of route guidance service for different devises and demands, but also ensure the framework of the existing system as far as possible.
