摘要： In a case where a CPU 11 provided in an information distribution center 3 has received a request command for requesting predicted traffic information transmitted from a navigation apparatus 2 as well as vehicle information such as a navigator identifying ID, coordinate data of a vehicle position, or coordinate data of a destination, the CPU 11 searches a basic route based on update-purpose map information 14A, and sets a distribution range serving as a transmission target of traffic information 16A, 16H, and 16C. Then, the CPU 11 generates the predicted traffic information 16C such as congestion prediction information corresponding to the distribution range, extracts the predicted traffic information 16C of each link having a difference in the generated predicted traffic information 16C and the current traffic information 16A, and distributes the extracted predicted traffic information 16C to the navigation apparatus 2 together with a link ID of a corresponding link.

摘要： A navigation apparatus outputs facility information needed by a user in a simple and easy-to-understand manner and includes a change processing unit. The change processing unit searches, responsive to a signal from a facility display change icon on a facility information display screen, facility information limited to those facilities that are in the direction of travel ahead of the current position, selected from among facility information stored in a facility information storage unit. Additional facilities within the output facilities are searched for within additional facility information stored in an additional facility information storage unit. Then all types of facility icons are displayed on a facility display change screen, but only facilities in the direction of travel from the current position are selectable. All types of additional facility icons are displayed on the facility display change screen but, again, only additional facilities in the direction of travel from the current position are selectable. Then, when the user selects facilities or facilities including the desired additional facilities, the three facilities nearest the current position are displayed on the guidance screen.
