Abstract

The invention discloses a method for describing traffic network information. The method for describing traffic network information comprises the following steps: constructing a basic object set for describing the traffic entity information according to data characteristics of traffic entities contained in a traffic network scene, wherein the basic object set comprises a plurality of basic objects;constructing a derivative object set for describing the traffic entity information in the traffic network scene by taking the constructed basic object as a basis according to traffic entities contained in the traffic network scene, wherein the derivative object set comprises a plurality of derivative objects. By adopting the method provided by the invention, more elastic description of the traffic network information is realized, and more requirements on the traffic network information in reality are met, so that a unified and flexible description mode is provided for various road network entities in a traffic network scene, and unified description of numerous and complex road networks is realized.

Description

technical field [0001] The present application relates to the field of traffic road network information processing, in particular to a method and device for describing traffic road network information. Background technique [0002] At present, the basic road network information is usually used to provide basic information to the navigation system, and the navigation system provides navigation services to users based on the basic information. [0003] However, the basic road network information is difficult to be applied in the creation of intelligent urban traffic. The main reason is that in the existing basic road network, the definition of data analysis objects is too rigid and lacks flexibility, and it is difficult to support in-depth data mining in the transportation field. , providing a unified and flexible data description method for various road network entities. Contents of the invention [0004] The present application provides a method and device for describing ...
