Embodiment Construction

[0025] In order to better understand the present invention, the road address information data format and road network topology definition involved in the present invention will now be described.

[0026] Firstly, the description granularity format of various main standard traffic information supporting conversion in the present invention and the format definition of the actual road are explained.

[0027] 1.Drm Link

[0028] Drm Link, also known as road link, is the smallest granular road unit defined in the navigation electronic map. It generally represents the road section between two adjacent intersections on the road and other road intersections. Its attribute information includes road link number, road Chain number, length of the link, distance from the starting point of the link to the end point of the road in this direction, number of points and array of points;

[0029] The link number is the unique number of the link in the entire road network;

[0030] The link num...

Abstract

The invention provides a management method of road information and a device thereof, relates to the processing application field of road information of urban road traffic and solves the problem that the efficient processing and releasing of real-time information can not be realized under the condition that various traffic information data sources with different granularities exist at the same time. The management method of road information comprises the following steps: road information data of different types are respectively converted into the primary data with corresponding formats; the primary data with different formats are converted into the data with the intermediate data format; a trigger is updated, and according to the data with the intermediate data format, road traffic information is updated. The invention is applicable to the efficient conversion processing and releasing of large-scale road and link traffic information data.

Description

technical field [0001] The invention relates to the field of processing and application of urban road traffic condition information, in particular to a dynamic and real-time road information management method. Background technique [0002] The main goal of intelligent transportation is to realize the modernization of the entire urban transportation system, and the key link in the modernization of urban transportation is the high degree of integration and sharing of various traffic information, as well as the provision of real-time dynamic traffic information services to meet the public's increasingly urgent traffic information needs . The real-time dynamic traffic information of the road has become an important foundation of the entire ITS (Intelligent Transport System, Intelligent Transportation System) information system. The real-time dynamic traffic information processing system is to generate real-time dynamic traffic condition information by integrating and analyzing ...
