Example Embodiment

[0032] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described here are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0033] figure 2 It is a flowchart of Embodiment 1 of a method for updating real-time traffic information according to the present invention. Such as figure 2 As shown, this embodiment includes:

[0034] Step S202: Collect and store real-time traffic information;

[0035] Specifically, real-time traffic information can be obtained from various real-time traffic information source platforms. The real-time traffic information source platform is responsible for processing the original real-time traffic information sources into information that can be applied. The collection of real-time traffic information sources can be based on location points to provide external data Time can ...

Abstract

The invention discloses a method and system for updating real-time traffic information. The method comprises the following steps: collecting and storing real-time traffic information; differentially comparing the collected real-time traffic information with the previously stored real-time traffic information to obtain changed traffic information; and generating updated real-time traffic information in accordance with the changed traffic information. The system and method provided by the invention can be used to realize incremental update of the real-time traffic information and blocked raster maps, thus greatly improving the update efficiency, shortening the update time of real-time traffic network maps, relieving server performances, reducing the update cost, and solving the technical problems of high cost, low efficiency and the like in the prior art.

Description

technical field [0001] The invention relates to data services and wireless communication technologies in the communication field, and in particular to a method and system for updating real-time traffic information. Background technique [0002] In recent years, Internet-based maps and geographic information services have developed rapidly. Internet map websites represented by "Google Map" have emerged. Users can find locations, stores, points of interest, etc. through this map. Currently, real-time traffic can also be viewed on Internet maps. information to understand real-time traffic conditions. [0003] In the prior art, the Internet map mainly adopts block grid map slicing algorithm or technology, which cuts and saves the rendered map into several map pictures according to a certain projection algorithm, and stores the map pictures in multiple file directories according to the law Next, use the "Ajax" component on the browser side to calculate the file name that compose...
