The real-time traffic system proposed in this paper is built as a mobile phone APP for Android 4.0 or above. This system uses the GPS real-time positioning information provided by mobile terminal, which is collected and screened by the VID (Vehicle Information Database) of a Cloud Server and fed back to the mobile terminal SQLite for access. It is calculated according to the present direction of mobile terminal. The real-time traffic diagrams are displayed. When the network is unavailable and the VID information cannot be acquired, Wi-Fi Direct search the users within the connection range, and acquire VID information from owner terminals with normal internet connection. Hence, complementary broadcast of real-time traffic can be achieved.
