Method, device and system of calculation of real time traffic status on the basis of information interaction

Abstract

The present invention discloses a method, device and system of calculation of a real time traffic status on the basis of information interaction. The method provided by the invention comprises: performing real time acquisition of positional information and movement speed information of a user terminal through the user terminal; sending a query request response to a cloud platform, extracting an average speed of a road with respect to the present position information from the query request response to take as a present average speed when the query request response sent by the cloud platform is received; and determining whether the present movement speed of the user terminal is larger than a driving lower limiting value or not, and reporting driving information to the cloud platform so as to allow the cloud platform to calculate real time traffic status through adoption of received driving information if the present movement speed of the user terminal is larger than the driving lower limiting value. Through the interaction of a user terminal and a cloud platform, driving information of the user terminal is reported only when the present movement speed of the user terminal is close to or larger than the average speed of the present road, therefore the accuracy of the real time traffic status may be improved, and the amount of network transmission and the amount of cloud calculating may be effectively reduced.

Description

technical field [0001] The present invention relates to the communication field, in particular to a method, device and system for calculating real-time road conditions based on information interaction. Background technique [0002] At present, the main model of collecting road conditions is the floating car model, which uses GPS (Global Positing System, Global Positioning System) to record (generally provided by taxi companies) the speed and direction of the floating car, and then calculates the road conditions according to road matching. Existing methods for judging road congestion mainly include traditional road condition information detection methods and GPS-based road condition information monitoring. [0003] The traditional road condition information detection method is to install ground sensing coils, speed radars and video monitoring tools on the main roads of the city. These devices are mainly used to detect traditional road condition information such as road occupa...

AI Technical Summary

Problems solved by technology

[0005] 1. It is necessary to deploy monitoring facilities on the monitoring road section, which requires a large investment and insufficient automation;

[0006] 2. Insufficient accuracy and real-time performance (for example, the road congestion prompt of Baidu map is not accurate)
