摘要： A route selection data storage unit 7 stores route selection data which are created from original data describing a detailed road system. When a plurality of crossings and a plurality of roads which are expressed on the road system in the original data satisfy prescribed conditions, these crossings and roads are integrated with each other respectively and recorded in the route selection data. The route selection data include a passage link table, so that links which are deleted by integration of the crossings are not missed. The passage link table records links which are deleted due to the integration of the crossings but passed in practice with reference to approach and escape links as to the respective crossings integrated with each other. An optimum route search unit 6 searches for the optimum route between a starting place and a destination which are designated by a position detection unit and/or a spot input unit 5 through the route selection data. When the optimum route obtained through the search passes through the integrated crossings, the optimum route search unit 6 supplements the deleted links with corresponding passage links recorded in the passage link table.

摘要： In a route selection process, an optimal route searcher 5 refers to a traffic light flag included in route selecting data stored in a second storage 4 to see whether a target intersection has any traffic light or not. When the optimal route searcher 5 determines that the target intersection has a traffic light s, a traffic light cost calculator 6 calculates a traffic light cost relevant to a waiting time due to the traffic light s. Based on the traffic light cost thus calculated by the traffic light cost calculator 6, the optimal route searcher 5 calculates a passage cost relevant to a time taken for passing the target intersection. In this manner, with consideration for the waiting time due to the traffic light, a time for going through an entire route can be estimated with higher correctness, thereby rendering the route thus searched more optimal.

摘要： In areas where composite intersection traffic regulation exits, nodes and links for use in the conventional network are separated into a plurality of nodes and links, respectively. For example, one node is separated into N1a to N1c, and one link is separated into L1a to L1c. Then, the whole road network is represented by separating the network into a road network (L1a, L2a, L3a, L4a, L5a, N1a, N2a) in view of entering links (L1a, L3a) which the composite intersection traffic regulation does not affect, and road networks .alpha. (L1b, L2b, L3b, L4b, N1b, N2b) and .beta. (L1c, L2c, L3c, L5c, N1c, N2c) in view of entering links (L4b, L5c) which the composite intersection traffic regulation affects, and one-way traffic regulations are set on suitable links to allow for a representation of the composite intersection transfer regulation. Use of such map data enables selections which are compliant with the composite intersection traffic regulation without requiring a specific processing at the time of the search processing.

摘要： An optimum route searching device 5 conducts a search in a predetermined area on road network data on a lower hierarchical level to obtain minimum arrival costs to individual nodes in the search area and then selects a node located on an upper hierarchical level existing in from the search area. Then the optimum route searching device 5 obtains a remaining cost to a node common with the upper hierarchical level which first appears on the upper hierarchical level existing link. Then the optimum route searching device 5 obtains a minimum arrival cost from the starting point of the search to the common node on the basis of the minimum arrival cost to the selected node and the remaining cost to the common node. The minimum arrival cost to the common node obtained at this time is used as initial conditions for a route search performed on the road network data on the upper hierarchical level. This makes it possible to shift the search results on the lower hierarchical level to the upper hierarchical level without causing an abnormal route such as a U-turn path and a bypass path.

摘要： In a navigation apparatus, a CPU searches for a plurality of routes from a starting point to a destination. These routes share the same starting point and the destination, but vary in their course along the way. Then for route selection, the CPU refers to position information provided by a locator to determine on which of the routes the user is now moving. In this manner, the navigation apparatus can automatically select one route from several derived through the route search.

摘要： Road network data is divided into a plurality of road network areas and one or a plurality of routes are obtained between the divided road network areas. The obtained routes are stored into a route data storage device 1. When a starting point and a destination are specified from a point input device 2, an area investigating device 3 investigates two road network areas to which the points belong. A route retrieving device 4 retrieves the route data corresponding to the combination of the obtained two road network areas from the route data storage device 1. A peripheral route searching device 8 searches for connecting routes in the road network areas to which the starting point and the destination belong, on the basis of the road network data stored in the road network data storage device 7. Further, the peripheral route searching device 8 produces the entire route from the starting point to the destination by using the route data retrieved from the route data storage device 1 and the connecting routes searched for in the vicinities of the starting point and the destination and presents the route to a user through an output device 6. This way, routes between arbitrary two road network areas are obtained in advance and stored as route data. When a starting point and a destination are specified, the route data between the corresponding road network areas are retrieved and a route from the starting point to the destination is presented on the basis of the retrieved route data. Thus the route can be searched for in an instant.

摘要： A route connecting a point and another point on a network is derived in advance with respect to entire pairs of two points, and the route is stored with a transit point placed on the route in a memory. When a route between two points is retrieved, the route is divided by the transit point, and a route in each division is retrieved. Subsequently, plural routes of the divisions are connected and thus the route between the two points is derived.

摘要： A navigation device at least includes a CPU and a detector generating a detection signal for determining whether a main device is used inside a vehicle or not. If determining, based on the detection signal from the detector, that the main device is used inside the vehicle, the CPU operates in on-vehicle mode to carry out first navigation (present position estimation and route search) suitable for use in the vehicle. Otherwise, the CPU operates in off-vehicle mode to carry out second navigation (present position estimation and route search) suitable for use outside of the vehicle. Thus, the navigation device can automatically switch its operation mode between on-vehicle mode and off-vehicle mode.
摘要翻译：导航装置至少包括CPU和产生检测信号的检测器，用于确定是否在车辆内使用主装置。如果基于来自检测器的检测信号来确定车辆内部使用主装置，则CPU以车载模式进行操作，以执行适用于车辆的第一导航（当前位置估计和路线搜索）。否则，CPU在离车模式下操作，以执行适合于在车辆外部使用的第二导航（当前位置估计和路线搜索）。因此，导航装置可以在车载模式和车外模式之间自动切换其操作模式。
