Problems solved by technology

[0005] The technical problem to be solved by the present invention is to provide a traffic information fusion processing method and system to solve the problem that the floating car data can only reflect the traffic road condition information of a certain point or a certain section of the driving route of each floating car alone, and cannot calculate the overall traffic information. The problem of comprehensive traffic information for roads
[0006] Another object of the present invention is to solve the problem of insufficient road coverage of traffic information due to the small number of floating cars

Embodiment Construction

[0055] In order to make the above objects, features and advantages of the present invention more comprehensible, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0056] The main goal of intelligent transportation is to realize the modernization of the entire urban transportation system, and the key link in the modernization of the urban transportation system is the high degree of integration and sharing of various traffic information, as well as the provision of real-time dynamic traffic information services to meet the increasingly urgent needs of the public. traffic information needs. Therefore, the real-time dynamic traffic information processing of the road has become an important basis of the entire ITS information system. The real-time dynamic traffic information processing system is used to integrate and analyze the collected traffic information source data, generate real-time dynam...

Abstract

The invention discloses a public transport information integrating and processing method and system, to resolve the problem that floating car data only reflects the traffic information in its routing trace, but cannot calculate the entire road traffic information. The method includes: iteratively read source data from all floating cars in a cycle; for source data from each car, calculate traffic information in different time segments; divide each road link that form a trace into road segment units, and calculate the traffic information of each unit; according to the traffic information of the units, calculate the traffic information of each road link, and then calculate the synthesized traffic information of each road.

Description

technical field [0001] The invention relates to information fusion technology, in particular to a traffic information fusion processing method and system. Background technique [0002] With the deteriorating urban traffic situation, many countries have carried out research and construction on Intelligent Transportation System (ITS). Intelligent transportation system is a general term for traffic systems that use traffic information systems, communication networks, positioning systems, and intelligent analysis and route selection for the purpose of alleviating road congestion, reducing traffic accidents, and improving the convenience and comfort of traffic users. The realization of intelligent transportation includes the collection, analysis and processing of traffic information, and release to the public. [0003] Traditional traffic information collection methods such as induction coils, detectors, video surveillance, etc., all belong to the fixed detection type, and use t...
