Abstract

Embodiments of the invention, which relate to a traffic information intelligence service field, disclose a link information difference method and an apparatus thereof. Updating of a real-time information of China (RTIC) version can be simplified and efficiency for publishing link information can be increased. The method of the invention comprises the following steps: acquiring a previous-edition RTIC map sheet and a next-edition RTIC map sheet, wherein the RTIC map sheet comprises: a link number, a link coordinate, a link direction, a link grade and a link shape; comparing the previous-edition RTIC map sheet and the next-edition RTIC map sheet so as to obtain a difference result; outputting the difference result. The method and the apparatus are mainly used in an intelligent traffic system.

Description

technical field [0001] The invention relates to the field of traffic information intelligent services, in particular to a road link information differential method and device. Background technique [0002] With the development of the modern automobile industry and the continuous improvement of people's living standards, vehicles have become a part of people's lives. However, with the acceleration of road construction and development, if the latest road information cannot be grasped during the driving process, the efficiency of travel will be greatly reduced, resulting in unnecessary waste of traffic resources. These problems not only bring a lot of inconvenience to people's daily travel life, but also cause huge economic losses to the society. [0003] In order to solve this series of traffic problems, in addition to the efforts made in the construction of road infrastructure and the formulation of related laws and regulations, countries in the world are working on using IT...
