Method and system for updating real-time traffic information

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...

AI Technical Summary

Problems solved by technology

[0006] 1. High cost and time-consuming: The city map has a wide range and high scale level, so the number of slices is huge, and the slices are time-consuming and costly

[0007] 2. The server has heavy tasks and low stability: the real-time traffic information is characterized by high real-time requirements, and the traffic information source is generally updated every 5 minutes. Therefore, the server needs to slice tasks with a large amount of data. The processing cycle puts forward very high requirements. Improper processing may cause system downtime and directly affect the use of the final product. Therefore, there is a risk to system stability
