Embodiment Construction

[0027] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention more clear, the embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings. Here, the exemplary embodiments and descriptions of the present invention are used to explain the present invention, but not to limit the present invention.

[0028] The processing flow of traffic information generally includes three stages: traffic information collection, traffic information analysis, and traffic information release. Among them, the data collection is to obtain the original traffic data in various formats; the traffic information analysis stage is to use the corresponding discriminant algorithm of each data source , to determine the traffic status of the road section; information release is to release traffic information, congestion, travel time and other business information. An important link in traffic ...

Abstract

The invention provides a multi-source traffic fusion method. The method includes the steps that traffic information data are acquired from three data sources of a mobile phone, a floating vehicle and traffic video images; pixel-level fusion is conducted on the traffic information data, and disqualified information in the traffic information data is removed; feature-level fusion is conducted on the traffic information data of each data source to generate road segment traffic state information of the three different data sources; decision-level fusion is conduced on the road segment traffic state information of the three different data sources to generate consistent traffic state description information of road segments; the traffic state description information of the road segments is output. The traffic information data are acquired from the multiple data sources, after three levels of fusion, final traffic states of the road segments are generated, and the traffic state of the road surface can be more accurately determined.

Description

technical field [0001] The invention relates to traffic data processing technology, in particular to a multi-source traffic data fusion method. Background technique [0002] Effective traffic information service plays an important role in private car control, traffic control and management organization. At present, most of the existing traffic information centers and intelligent transportation systems (ITS) rely on single traffic data resources, such as GPS vehicle positioning / speed, monitoring video images, coil detection speed, vehicle traffic conditions, etc. Each of these resources has its own advantages and limitations. Only relying on any one of the above-mentioned resources cannot provide accurate traffic information services at a reasonable cost, and other traffic information is wasted. Contents of the invention [0003] The present invention provides a multi-source traffic data fusion method, which is used to perform three-level fusion of traffic information dat...
