Multi-source traffic information fusion method

Abstract

The invention provides a multi-source traffic information fusion method which comprises the following steps: all kinds of traffic information is preprocessed and is on a unified processing road network; the preprocessed traffic information is fused in a weighting method, and road sections without traffic information coverage after fusion are filled to form complete traffic information; and the complete traffic information is generated and released according to a standard position. According to the invention, floating car traffic information is fused with non-structured traffic information such as micro-blog information, event information, traffic website information and the like, and historical traffic information is used as a data source and fused with real-time traffic information based on the rules of the historical traffic information.

Description

technical field [0001] The invention relates to the field of intelligent traffic, in particular to a fusion method of multi-source traffic information. Background technique [0002] In the field of intelligent transportation, real-time dynamic traffic information services can provide efficient and feasible traffic guidance and travel planning information for public travel, transportation, etc., so as to save time, reduce costs, and low-carbon environmental protection. At present, the traffic information service in the city can provide the traffic control department with the basis of traffic control and management, and provide the reference basis for the road planning department to reasonably plan road facilities, so as to achieve the purpose of alleviating traffic congestion, energy saving and emission reduction, and it has been deepening and affecting people. travel life. [0003] At present, the equipment that can be used as traffic information collection mainly includes ...

AI Technical Summary

Problems solved by technology

[0006] Fixed-point detection equipment includes video, coil, infrared, etc., but the cost of equipment and labor maintenance is high, and it is easily affected by conditions such as weather and light, so only a limited number can be installed

Due to China's national conditions and resource sharing issues, it is difficult to obtain data sources for fixed-point testing equipment

Therefore, it is difficult to effectively provide traffic information services due to the difficulty in obtaining data resources of fixed-point detection equipment and its limited resources.
