摘要： A traffic information generation method for generating traffic information for each link includes a vehicle speed detection step of detecting a vehicle speed at predetermined distance intervals or at predetermined time intervals using a vehicle speed sensor; and a traffic jam degree detection step of referring to a specified speed and a specified distance prescribed in association with a traffic jam degree representing a level of a traffic jam and a connection determination distance prescribed in accordance with a road type to detect the traffic jam degree corresponding to the vehicle speed. When a link length falls within a predetermined range, information on the traffic jam degree corresponding to a fastest vehicle speed within a prescribed starting point distance from a beginning of the link is allocated to the link.

摘要： Navigation systems, methods, and programs store traffic information and crated prediction traffic information based on the stored traffic information. The systems, methods, and programs search a plurality of routes to a destination, each route including at least one link and calculate a predicted passage time of each link in each route. The systems, methods, and programs obtain, for each link, prediction traffic information at the predicted passage time, based on the created prediction traffic information and extract the obtained prediction traffic information pertinent to route-search-as information to be distributed, according to a predetermined order of priority.

摘要： Method and apparatus for searching for a navigation route search a tentative route from a start point to a destination, based on hierarchical map data. The methods and apparatus search for a start-area route from the start point to a point on the tentative route at which wide-area map data is connected to local-area map data, based on the local-area map data and traffic information and search for a destination-area route to the destination from a point on the tentative route at which the wide-area map data is connected to the local-area map data, based on the local-area map data and the traffic information. The methods and apparatus determine a navigation route from the start point to the destination, based on the start-area route, the tentative route, and the destination-area route.

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： Navigation systems, methods and programs for a vehicle detect a number of travel lanes available for traveling in a direction that the vehicle is traveling. The systems, methods, and programs detect a lane in which the vehicle is currently located and determine a congestion degree for each of the available travel lanes. The systems, methods, and programs determine a degree of difficulty of turning right or left at a next intersection that the vehicle is approaching based on the detected number of available travel lanes, the detected lane in which the vehicle is currently located, and the detected congestion degree. The systems, methods, and programs select a travel route in accordance with the determined degree of difficulty and provide guidance information on the selected travel route.
