摘要： A voice route-guidance system for vehicles which terminates its route-guidance when the vehicle arrives at the destination and even if the present position of the vehicle is measured with low accuracy. An approach judging unit judges that the vehicle approaches a point spaced apart from a destination by a predetermined distance. A guidance termination judging unit further judges whether or not there is a point in which the route-guidance should be carried out between the present vehicle position and the destination. From these judgments, the system judges that the vehicle approaches the point spaced apart from the destination by the predetermined distance and also that all the route-guidance has been terminated. Thus, a termination unit terminates the route-guidance.

摘要： Even when the present position does not exist on a guide road after deviation from an established guide route, a guide road is identified and a more advantageous route is identified. Furthermore, only a minimum amount of required data are displayed on the map picture. The searching again is executed by taking the direction of progress of the car into consideration. Street names of the roads are displayed on the guide map, enabling a guide route to be easily recognized. A particular area is specified by a postal code number or by a telephone number, and the streets or the facilities in the specified area are displayed. This makes it easier to search the destination.

摘要： According to the invention, when a target name is inputted using characters such as alphabet and numerics, strings of characters or numerics are compared with data of registered places each time one character is inputted, names of registered places including the inputted string of characters or numerics is listed, and the number of registered target names remaining on the list is displayed. When the target name is inputted in characters, the inputted data is compared with a list of the registered names having word components arranged in different orders with respect to a single official name by a forward match comparison, and the number of registered target names remaining on the list with forward match is displayed. When the number of the inputted characters or numerics increases and the number of registered target names remaining on the list decreases, a list of the registered place names is displayed. The target name is selected from this list. When the number registered target names remaining on the list is one, the target name is selected. A map of the vicinity of the target name thus selected is displayed.

摘要： A navigation device stores road data in a storage part. The road data includes a consecutive connection of a plurality of links as a link queue, the plurality of links acquired by sectioning a road length into a plurality of pieces. The navigation device includes a guidance part that performs route search and guidance to a destination using the road data. The link queue includes a standard link for which, based on a sectioned link of a specific road stored in the storage part, information relating to the sectioned link is stored as road-related information in the storage part, and an invariance link for which the road-related information is not stored in the storage part if there is no difference in the road-related information compared to an adjacent link in the link queue. A navigation road data creating device is also provided.

摘要： The present invention provides a navigation system for guiding a driver along an optimum route by comparing a route with preference on the traveling direction of a vehicle with a route with no preference on the traveling direction thereof when the driver is guided from the current position thereof up to a destination. To search for a route, a first route with preference on the traveling direction of a vehicle is calculated (1) and then, a second route with no preference on the traveling direction thereof is calculated (2). An appropriate route is selected from found routes according to a predetermined setting condition (3) and displayed on screen. The setting condition includes comparison of distances of respective routes and time lengths required for traveling thereon, ease of traveling, width and type of roads, scenery and the like. In a case where distances of the respective routes, for example, are compared with each other, if the distance of the first route is longer than the second route by at least a predetermined value, the second route is displayed, and if the first route is not longer than the second route by at least the predetermined value, the first route is displayed.

摘要： Navigation apparatuses, methods, and programs having conducted a search for an original driving route that goes through a plurality of destinations in a designated order and provided route guidance based on the original driving route, receive an input of a new destination. Upon receipt of the new destination, the apparatuses, methods, and programs designate an ordinal position of the new destination in terms of the designated order and receive an input of a destination change request. When the destination change request is received, the apparatuses, methods, and programs automatically delete one or more of the destinations in ordinal positions within the designated order that are before the ordinal position of the new destination, conduct a new search for a new driving route based on the new destination, and output the new driving route. When an added destination request is received, the apparatuses, methods, and programs conduct a search for the new driving route including the new destination, without deleting destinations in ordinal positions within the designated order that are before the ordinal position of the new destination.

摘要： Systems, methods, and programs for navigation guide to a destination along a searched route and receive road information and traffic information including traffic congestion information. If according to the received traffic congestion information, traffic congestion is detected on the guidance route, the systems, methods, and programs search a detour route to avoid such congestion. The systems, methods, and programs guide to a destination along the detour route. If traffic congestion which was previously avoided by the detour route is determined to have been eased, the systems, methods, and programs search for a new route and switches guidance from the detour route to the new route.
