The innovation of urban road navigation by “automobile network”

Build the Wi-Fi nodes covering the urban streets; identify the directions and quantity of the moving automobiles by the communication between the mobile terminal and the Wi-Fi node, and form dynamic data in the general data base; comparing these data with the pre-designed automobiles in the streets, we can complete the investigation of the crowding conditions of automobiles in the street. By accessing the data center, the auto PC in the mobile terminal can reflect all the streets´ data image vividly, and then establish the search system to complete the automatic navigation system.
