[0018] see figure 1 Shown, a kind of accurate dynamic traffic information voice broadcasting method based on GIS data of the present invention is characterized in that, comprises the steps:
[0019] Step 1. Load the geographic information system GIS data, and initialize the map information data at the vehicle terminal;
[0020] Step 2, open the traffic information reading detection thread, and update the traffic information in a loop; simultaneously open the user request detection thread, respond to the user request, and analyze and obtain the GPS data of the user's request by the network protocol (i.e. the TCP link process);
[0021] Step 3, geographic information system GIS platform obtains the driving data of user's history from database, according to the driving data of user's history and described GPS data, obtains user's current road position and user's expected driving road;
[0022] Step 4. Accurately match the user's expected driving road with the traffic information...
