摘要： A route searching method is provided which allows drivers having mutually similar traveling purposes and preferences to find highly convenient routes by sharing their route searching know-how. A center apparatus (1) collects probe data received from an in-vehicle terminal apparatus (5). A preference parameter creating unit (14) calculates, based on the probe data, road usage frequencies according to preference items such as vehicle type, driver age and gender, and travel purpose which can be factors for route selection and stores the calculated road usage frequencies as preference parameters in a preference parameter database (15). A route searching unit (513) included in the in-vehicle terminal apparatus (5) requests the center apparatus (1) to transmit a preference parameter similar to user attribute information (519), adjusts link costs according to the preference parameter received from the center apparatus, and determines a minimum-cost route to a destination.

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.

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.
