With the rapid development of communication and network technology, vehicle navigation technology is gradually to the evolution of dynamic network navigation. As dynamic navigation traffic information service platform save a few weak technical problems, this paper presents a hierarchical framework of dynamic navigation traffic information service platform. The framework consists of the data provider layer, dynamic navigation information service layer, communication layer and user layer. In this paper, the framework of the platform, software architecture, database creation and distribution protocol are researched, and the B/S and C/S mixed mode of traffic information service technology platform is realized.
