摘要： Disclosed is a traffic information distribution apparatus 1 including date-time information in traffic information acquired by the traffic information acquire unit 12 or generated by the traffic information prediction unit, and accumulates the traffic information in the traffic information DB 13. When the traffic information distribution apparatus 1 receives distribution request information transmitted from the in-vehicle terminal 5, based on date-time information of reference traffic information held by the in-vehicle terminal 5 included in the distribution request information, the traffic information distribution apparatus 1 retrieves traffic information including the same date-time information as the date-time information of the reference traffic information from the traffic information DB 13. Then, difference traffic information generation unit 18 generates difference traffic information between the retrieved traffic information and traffic information to be distributed, and the traffic information distribution apparatus 1 distributes the generated difference traffic information to the in-vehicle terminal 5.

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： A server device 1 included in the route-search system 7 comprises a guided-navigation-route-search section 130 for searching a route starting from a departure point and reaching a destination; and a preparatory-route-search section 140 for searching a preparatory route in view of a possible deviation of the vehicle from a navigation route. The server device 1 transmits information on the navigation route and the preparatory route to the navigation device 2. When detecting the deviation of the vehicle, the navigation device 2 selects one of preparatory routes having nodes closest to the current position of the vehicle. The navigation device 2 searches a supplementary route connecting the current position of the vehicle to the nodes, and combines the preparatory route with the supplementary route to create a new route for continuing navigating the vehicle to the destination.
