Embodiment Construction

[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...

Abstract

The invention provides an accurate dynamic voice broadcast method of traffic information based on GIS data. The voice broadcast method comprises that 1) the GIS data is loaded, and map data is initialized in a vehicle terminal; 2) a traffic information reading and detecting process is started to update the traffic information in a cycled manner, and at the same time, a user request detection process is started to make response to user requests and obtain GPS data of the user requests; 3) a GIS platform obtains historical driving data of a user from a database, and the present road position where the user is placed and an expected driving road of the user are obtained according to the historical driving data and GPS data of the user; 4) the expected driving road of the user is accurately matched with the traffic information to obtain dynamic driving traffic information that satisfies the user requirements; and 5) the GIS platform packages the dynamic driving traffic information into a data message and transmits the data message to the vehicle terminal, and the vehicle terminal implements voice broadcast. The travel quality is improved, the dynamic traffic information can be accurately pushed to different users, and useless traffic information is reduced and filtered.

Description

technical field [0001] The invention relates to the technical field of intelligent transportation, in particular to a voice broadcasting method for precise dynamic traffic information based on GIS data. Background technique [0002] The precise dynamic traffic information voice broadcasting method of geographic information system GIS data is an extension product based on the existing real-time road conditions combined with the application of map display technology. It is a trend of future navigation functions for people to travel, especially in large and medium-sized cities. The roads are criss-crossed and complex, and the traditional static display of road conditions on the map requires users to observe the changes of road conditions on the map from time to time, which seriously affects the driving safety of users and cannot meet the requirements of users. In this situation, the real-time broadcast of real-time traffic broadcast technology The road condition product shows i...
