Abstract: The basic idea of intelligent transport systems(ITS) is introduced in this paper. GPS/INU/DM integrated navigation & location technology and its application in ITS are described. In addition, several technical measures to increase integrated navigation & location precision and reliability are presented. This technology combines satellite navigation, inertial navigation with information technologies, and has all-direction, 24 hours standby and non-shadowed characteristics. The ‘automation’ of transportation management and the ‘intelligence’ of vehicular driving will be realized through using of integrated navigation & location technology. Integrated navigation & location technology has better practicing value and widely prospect. -
