A method for obtaining graphical real-time traffic information

Abstract

The invention provides an acquisition method of graphical real-time traffic information and belongs to the field of intelligent transportation. The acquisition method includes the steps: a terminal device uploads current arrived position geographic coordinates, driving direction and driving speed to a traffic information service platform; the traffic information service platform determines a section number of a road section where a vehicle locates, according to the uploaded position geographic coordinates; according to the position geographic coordinate s, the driving direction, the driving speed and the section number, the traffic information service platform searches for graphical real-time traffic information of at least one intersection, possibly passed in a preset range in front of or around the vehicle, and transmits the graphical real-time traffic information to the terminal device for displaying. The acquisition method has the advantages that the graphical real-time traffic information of the intersections ahead that a user possibly passes by can be displayed in the driving process, the fact that the user knows of jamming of a road section till approximately reaching the road section is avoided, the user can optimally select to drive on the smooth road section, and the jamming road sections are avoided better.

Description

technical field [0001] The invention relates to the field of intelligent traffic, in particular to a method for acquiring graphic real-time traffic information. Background technique [0002] With the increasing urban congestion and the continuous development of intelligent transportation, more and more users are using real-time traffic information. [0003] At present, the application of displaying road conditions through various navigation terminals (navigators, mobile phones, etc.) has become very popular. However, it is difficult for the driver to recognize the road conditions of the main road ahead from the map of the navigation terminal when the driver is concentrating on driving. In order to clearly and clearly display the main road conditions ahead, many products display the road conditions ahead in the form of simple maps.

AI Technical Summary

Problems solved by technology

[0005] However, the existing technology only provides a method for generating graphical real-time road conditions and a selection principle for triggering positions of graphical real-time traffic information, but cannot provide road condition information for multiple intersections ahead.

[0006] Taking the patent application of 201110308758.8 as an example, it provides a method for selecting the trigger position of graphical real-time traffic information, but it can only provide graphical real-time traffic information of one intersection ahead, and cannot provide the road conditions of multiple intersections ahead
