MTISS: A Novel Mobile Transportation Information Service System Based on SOA

One of the major problems that limit the practical realization of Intelligent Transportation System is collecting and distributing transportation information rapidly and effectively. Aside from traditional passive means, mobile devices, such as smart phones, could be exploited to collect various types of transportation information from individuals in massive quantities interactively as well as deliver guidance and navigation signals to the public to achieve purposes like congestion avoidance. This paper proposes a Mobile Transportation Information Service System (MTISS) which integrates client-end applications with SOA-enabled server-end web services. A unified, loosely-coupled and scalable architecture is presented. Then a prototype on Android platform and Windows Communication Foundation (WCF) is implemented. The key techniques are discussed. Application scenarios and the features of MTISS are addressed. Finally, experiments are conducted to evaluate the overall performance of the MTISS prototype and the results indicate that our system has high usability, scalability and efficiency.
