摘要： A position coordinate based route transmitted from a server is reconstructed as a route of link numbers or node numbers in map data of navigation apparatus without error. A route guidance server searches a route from a start point to end point designated by a navigation apparatus; selects all or a part of nodes included in the searched route as route nodes; sets complementary points to the respective selected route nodes on the route and at a distance longer than a predetermined distance from the respective route nodes; and transmits information including coordinate information on the route nodes and complementary points as route information to the navigation apparatus. Then, based on the coordinate information on the route nodes and complementary points transmitted from the server, the navigation apparatus identifies the route nodes and road links connecting the route nodes by identification numbers in map data the navigation apparatus it self has.

摘要： A navigation device displays predicted traffic information downloaded from a server device and statistical traffic information stored in a storage unit, on the same screen. Both information items may be displayed in such a manner that at least a part of them is overlaid (a superimposed display). The predicted traffic information may be superimposed on the statistical traffic information. When traffic information of the same time band of the same object (link, mesh area) exists in both the information items, one thereof may be selected to be displayed.

摘要： There is provided a method and a device for accurately estimating traffic information of a link having no traffic information even if different types of roads are mixed. The device finds a parameter characterizing a damping curve of a quantity of change of relative speed based on stored traffic information for links on a city center side on a minimum-time cost route connecting the city center and suburbs, finds a quantity of change of relative speed of the link having no observed traffic information and estimates its traffic information based on the damping curve. The device also calculates a ratio of quantities of change of relative speed of two links whose road types change as a speed change similarity ratio and estimates traffic information of the link of a second road type from known traffic information of the link of a first road type by using that ratio.

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.

摘要： A technique which enables a navigation system mounted on a vehicle or the like to be connected with an information providing device by utilizing a short range base station. In cases where a recommended route passes through a communication spot, which is an area enabled for communication by the short range base station, the navigation system is connected with the information providing device through the base station, after moving as far as the communication spot, and in cases where the recommended route does not pass through the communication spot, the system is connected with the information providing device through a public network by a communication terminal.

摘要： Route search is performed considering the fact that traffic conditions differ according to lane even for the same road. A navigation device performs route search, using link costs (link travel times) classified by lane. For example, the navigation device searches for a route having the lowest total cost to the destination, using link data that determine cost for each lane of a component link of a road on a map. A cost of a lane on which a vehicle runs to move to a next link, being the cost of any lane of the link, is used as a cost of a link on a route.

摘要翻译： 进行路线搜索是考虑到交通条件因道路而异，即使对于同一条道路也是如此。 导航装置使用按车道分类的链路成本（链接行驶时间）来执行路线搜索。 例如，导航装置使用确定地图上道路的分量链路的每个车道的成本的链接数据来搜索具有最低总成本的路线到目的地。 车辆运行到下一个链路的车道的成本（作为链路的任何车道的成本）被用作路由上的链路的成本。
