Problems solved by technology

[0003] During the research and practice of the prior art, the inventor found the following problems in the prior art: the existing road condition acquisition system basically uploads the original location information obtained by the acquisition terminal directly to the server, and then performs the original location information on the server side. Location point filtering, road mapping, and road condition information calculation, etc., require the server to have high computing and processing capabilities, resulting in high server costs, and, due to the limited processing capabilities of the server, real-time traffic information processed in parallel volume is very limited

specific Embodiment approach

[0102] The server calculates the average speed between the two points by using the relevant information values ​​in the information of the two adjacent points, and determines whether the real-time road condition between the two points is congested, slow or smooth according to the average speed.

[0103] Specifically, after receiving the above-mentioned points extracted according to the speed value, the server side will analyze and determine the actual path passed, and according to the length of the actual path passed between two adjacent location points and the travel time (that is, the distance between the two points) Collecting time difference), the average speed between the two points is calculated by dividing the length by the travel time. The server side just can determine the real-time road condition between these two points according to the average speed as congested, slow-moving or unimpeded.

[0104] In a specific application, when the server calculates the real-time ...

Abstract

The invention discloses a method and a device for processing traffic information in real time and relates to the field of navigation. The method comprises the following steps: collecting information of a position point by a collecting terminal according to a preset time interval; correcting the information of each position point by utilizing pre-stored map data; and uploading the corrected information of the position point to a server. The device comprises a collection module, a position correction module and an uploading module. In the embodiment of the invention, the position of an original position point is corrected at the collecting terminal, and the corrected information of the position point is uploaded to the server, so that the calculating pressure of the server is effectively reduced, thereby the parallel processing capability of the server is greatly increased and the operation cost of the server is sharply reduced.

Description

technical field [0001] The invention relates to the field of navigation, in particular to a real-time traffic information processing method and device. Background technique [0002] Float Car Data technology, also known as "Probe car" technology, is one of the advanced technical means used in the International Intelligent Transportation System (ITS) to obtain road traffic information in recent years. The basic principle is: a floating car equipped with a vehicle-mounted global positioning system regularly records information such as the vehicle's position, direction and speed during its driving, and transmits these position information regularly and in real time through a wireless communication system (for example, every few days) Ten seconds or several minutes, etc.) to the server (also known as information processing center), the server will carry out comprehensive processing, specific application filtering, map matching, path estimation and other related computing models ...
