摘要： In a center apparatus, a feature space projection processing unit performs a feature space projection process for probe data corresponding to a road section which are stored in a current probe data storage unit to extract the feature data, and a change point detecting unit; an event section partitioning unit and an event assigning unit 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 distributes the event information assigned to the road section. In a vehicle-installed terminal apparatus, a probe data partitioning unit and an orthogonal component decomposition unit performs processes of partitioning and orthogonal component decomposition of the probe data using a feature score vector obtained from the center apparatus, to thereby reduce the probe data to be uplinked.

摘要： A traffic situation is predicted based on the correlation in the traffic situation between road sections. A base vector generation unit generates the base vectors constituting a feature space representing the correlation between a plurality of links by making a principal component analysis for the necessary time in the past recorded in a necessary time database. A projection point trajectory generation unit records a projection point trajectory of projecting the necessary time in the past recorded in the necessary time database to the feature space in a projection point database. A feature space projection unit projects the necessary time at present to the feature space, and a neighboring projection point retrieval unit retrieves a past projection point in the neighborhood of the concerned projection point from the projection point database, and a projection point trajectory trace unit traces the trajectory of past projection points starting from the retrieved neighboring projection point for a prediction target time width, and an inverse projection unit inversely projects the end point of the concerned trajectory to calculate the predicted value of the necessary time.

摘要： In a traffic information system, the principal component analysis of the floating car data collected in the past is performed for each traffic area. From among the bases representing the traffic data collected on the road-links in the traffic area, the bases which have strong correlation to the road-links on which real-time traffic data were collected are selected. The weighting coefficients for the selected bases are calculated by projecting the real-time traffic data onto the selected bases. The traffic estimation data are calculated by linearly combining the selected bases with the obtained weighting coefficients as the coefficients of the respective bases. The calculated traffic estimation data are used for the interpolation of the road-links on which the real-time traffic data were not collected.

摘要： When receiving a traffic information providing request, a traffic information providing apparatus analyzes which area's traffic information is requested based on the received request information. Traffic information of road links located in the requested area is read from the traffic information, and it is determined whether the road links' traffic information is similar or not. Similar links configure a link group, and traffic information corresponding to the link group is created. Traffic information of the configured link group is delivered to an in-vehicle information apparatus.
