Embodiment Construction

[0050] In the method and device for distributing dynamic traffic information in the embodiment of the present invention, after selecting a certain road composition and using the links of the road to form an electronic map, the links in the electronic map are identified with digital IDs, and the number of each link is The IDs are different and have certain regularity, which can reduce the amount of data sent when dynamic traffic information is released.

[0051] Such as figure 1 As shown, the method for publishing dynamic traffic information in the embodiment of the present invention includes:

[0052] Step 11, obtaining first links used to represent roads in the first electronic map, each of the first links includes and only includes two nodes as endpoints;

[0053] Step 12, setting a one-to-one corresponding digital ID for each first link in the first electronic map;

[0054] Step 13, recording the correspondence between the first link and the digital ID in the database of ...

Abstract

The invention discloses a method and a device for distributing dynamic traffic information, solving the problem in the prior art that after data is updated, a user having the old edition electronic map can not be ensured to normally receive information. The method comprises the steps: first links which are used for indicating roads are obtained in a first electronic map, the first links in the first electronic map are provided with digital identifications ID which correspond to the first links one by one, and the corresponding relation of the first links and the digital identifications ID is recorded in a database of the first electronic map; when the roads in the first electronic map are changed, the digital ID of a second link which corresponds to the changed road in the first link is reset, and the second link is restored into a second electronic map. When the dynamic traffic information is distributed, the digital IDs of the second link in the first electronic map and the second electronic map are transmitted at the same time. The users who use different editions of electronic maps all can correctly receive the issue information of dynamic traffic information and can reduce the transmitting quantity of the information.

Description

technical field [0001] The invention relates to the technical field of electronic map data processing, in particular to a method and device for publishing dynamic traffic information. Background technique [0002] In the existing electronic map for distributing dynamic traffic information, each road is represented by a link (LINK), that is, represented by a line segment. [0003] In order to realize the release of dynamic traffic information, it is necessary to set a unique digital ID for each link. When publishing dynamic traffic information, the digital ID can represent a link. [0004] However, in the process of realizing the present invention, the inventor finds that the prior art has at least the following disadvantages: [0005] In the existing electronic map used for dynamic traffic information publishing, although each link has a unique ID, which guarantees its uniqueness, after the data is updated, it cannot be guaranteed that users of the old version of the electr...
