However, for Chinese cities with large cities and complex urban road conditions, the amount of RDS-TMC messages is very large. If the European general real-time traffic information release strategy is adopted, only part of the RDS-TMC messages can be released within the specified time. There are many important RDS-TMC messages that cannot be released, resulting in insufficient real-time traffic information received by the vehicle navigation system and reducing the reliability of vehicle dynamic navigation

Embodiment Construction
[0020] In order to make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions provided by the embodiments of the present invention will be described in detail below with reference to the accompanying drawings.
[0021] See figure 1 , Is a flowchart of a method for screening real-time traffic information provided by the first embodiment of the present invention, and the method includes:
[0022] Step 101: Read the real-time traffic information release status of the road. If the release status is the real-time traffic information released on the road, go to step 102, otherwise, go to step 105;
[0023] In the embodiment of the present invention, real-time traffic information includes: general traffic problems, weather conditions, road event background (for example, congestion caused by an accident) and its severity (for example, the length of the queue caused), etc.
[0024] Step 102: Determine whether the real-ti...

The invention provides a method and a device for screening real-time traffic information. The method comprises the following steps of: reading a real-time traffic information release state of a road; judging whether released real-time traffic information is same as real-time traffic information to be released of the road or not if the release state is that the real-time traffic information of the road is released; and discarding the real-time traffic information to be released if the released real-time traffic information is same as the real-time traffic information to be released of the road. The screening device comprises a release state judgment unit, a release content judgment unit and an information discarding unit, wherein the release state judgment unit is used for reading the real-time traffic information release state of the road and triggering the release content judgment unit if the release state is that the real-time traffic information of the road is released; the release content judgment unit is used for judging whether the released real-time traffic information is same as the real-time traffic information to be released of the road or not; and the information discarding unit is used for discarding the real-time traffic information to be released which is same as the released real-time traffic information. By the method and the device, more comprehensive real-time traffic information can be released, and the reliability of dynamic navigation of a vehicle can be improved.
Description
Technical field [0001] The invention relates to the technical field of intelligent transportation, and in particular to a method and device for screening real-time traffic information. Background technique [0002] With the rapid economic development and the increasing population expansion, the number of motor vehicles has increased sharply. As the growth rate of motor vehicles far exceeds the construction speed of roads and transportation facilities, the pressure on urban road traffic is increasing, and the contradiction between people and vehicles is increasing. The contradiction between vehicle and road has become increasingly prominent. [0003] With the widespread application of computer, information and communication technologies, people are working to use a new technology to improve the efficiency of road resources, and to improve the speed and safety of travel. This new technology is called Intelligent Transportation System (ITS). ITS is an open and complex system that int...
