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 present invention relates to information fusion technology, in particular to a method and system for processing traffic information fusion. Background technique

[0002] With the deteriorating urban traffic conditions, many countries have carried out research and construction on Intelligent Transportation Systems (ITS). Intelligent transportation system is a general term for transportation systems that use traffic information systems, communication networks, positioning systems, and intelligent analysis and route selection for the purpose of alleviating road congestion and 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., are all fixed detection types,...
