OGSA-Based Traffic Information System

As a complicated system, the intelligent transportation system (ITS) encounters the difficulties of resource sharing and service coordination in conventional network environment, which influences the further development of ITS. The feature, which utilizes grid technology to establish traffic grid application environment to achieve sharing and coordination, offers a new way to resolve such problem. Information grid can provide stronger computing and more resource sharing by integrating heterogeneous computers for complicated distributed traffic system. This paper analyses the relation of traffic services and presents a traffic information system based on open grid service architecture standard (OGSA-based). The OGSA-based traffic information system realizes resource sharing and promotes computing efficiency with grid in selection of optimal travel scheme. Simultaneously, it is the demonstration of practising and applying information grid technology. It can promote further study and development of information grid technology and offer better services for traffic information users
