System and method for collecting and distributing traffic information

摘要

The invention relates to a system and a method for collecting and distributing traffic information, wherein in a center apparatus (10), a feature space projection processing unit (14) performs a feature space projection process for probe data corresponding to a road section which are stored in a current probe data storage unit (21) to extract the feature data, and a change point detecting unit (15); an event section partitioning unit (16) and an event assigning unit (17) determine a road section corresponding to the feature data, and assign the event information to the determined road section; and an event information distributing unit (18) distributes the event information assigned to the road section. In a vehicle-installed terminal apparatus (30), a probe data partitioning unit (34) and an orthogonal component decomposition unit (35) performs processes of partitioning and orthogonal component decomposition of the probe data using a feature score vector obtained from the center apparatus (10), to thereby reduce the probe data to be uplinked.
