Roads traffic speed calculating and matching method and system

Abstract

The traffic speed counting and matching method for road traffic includes: fetching position information of mobile terminals from collected traffic data information; when the position information of the mobile terminals is lost, according to the change information of the position information of the mobile terminals, dynamic predicting and obtaining the position and speed information of the mobile terminals by using follow-up arithmetic; matching the position and speed information of the mobile terminals onto a road network to generate road traffic speed information. The road traffic speed counting and matching system is also disclosed. The method and system can provide exact traffic condition information to traffic managers and going out people.

Description

technical field [0001] The present invention relates to a method and system for calculating and matching the traffic speed of road traffic, in particular to a method and system for determining the traffic speed of the road where the mobile terminal is located by analyzing and calculating the location information of the mobile terminal, and further providing users with the current road traffic conditions . Background technique [0002] With the rapid development of the economy, there are more and more vehicles, which leads to more and more serious road traffic congestion in cities, especially in big cities, which brings great inconvenience to traffic managers and travelers. If the traffic conditions can be displayed correctly , giving vehicles reasonable scheduling and guidance can greatly alleviate the current situation of traffic congestion. At present, the collection and release technology of dynamic traffic information is relatively mature. Dynamic traffic data can be me...

Problems solved by technology

[0003] Although traffic information navigation has solved the technical problems of information collection and release, the technology of traffic data processing and processing is quite lacking.

[0004] Currently existing methods mainly focus on using mobile terminals to obtain traffic flow information. For example, Chinese patent 200480008487 discloses a method for obtaining traffic information using mobile terminal billing information. The billing information necessary for the billing operation is used to obtain the designated number of the mobile terminal, track the moving time of the mobile terminal between base stations, and obtain the traffic status information on the road. Sometimes, the location of the mobile terminal cannot be determined at a certain moment or within a certain period of time due to the failure of the mobile terminal itself or interference from the surrounding environment. For example, in a newly completed underground tunnel, since the communication system has not been installed, GPS car navigation system or other location recognition systems will therefore be unable to determine the location of the mobile terminal, thereby failing to guarantee the continuity and integrity of data information, resulting in the inability to provide correct traffic condition information

[0005] In addition, this invention does not involve screening the location information of mobile terminals, because not all mobile terminals can represent road traffic conditions, for example, mobile phones carried by pedestrians cannot represent road traffic conditions, and the existing methods do not The terminal data information is screened, resulting in a large error between the statistical traffic flow data and the actual road traffic conditions. Places with large traffic volumes do not represent road congestion, and places with small traffic volumes may also be very congested, so that traffic status information cannot be provided correctly.
