Guiding Route Generation Device and Guiding Route Generation Method
First Claim
1. A guiding route generating device characterized by comprising:
- storage means for storing a guiding route generated based on specification of a position as a route used in guiding a route;
display means for displaying the guiding route stored in the storage means with roads in the periphery of the guiding route;
specified route determining means for determining whether the road based on passage specification by a user among the roads displayed with the guiding route is available as a part of a route from a starting point to an ending point of the guiding route or not;
generating means for generating an alternative route for a place unavailable of the road if the road specified to pass through by the specified route determining means is determined as unavailable; and
updating means for updating a part or the entire of the guiding route stored in the storage means with the route which combines the road determined as available by the specified route determining means and the road of the alternative route generated by the generating means.

Abstract
When a user specifies a road that he/she wants to pass through, a guiding route generation device generates a guiding route that passes through the specified road up to a destination. A guiding route (37) generated based on waypoints specified is stored in a storage means (15) of the guiding route generation device. A display means (11) displays the guiding route (37) along with roads in the periphery. The guiding route generation device specifies a certain road as the specified pass-through road from among the roads displayed along with the guiding route (37), and further, finds and determines whether there are crossings and the number of the crossings between the specified pass-through road and the guiding route (37). When there is no crossing, the guiding route generation device generates two routes between the specified pass-through road and the guiding route (37) and extends the specified pass-through road to generate a user-specified road. When there is one crossing, the guiding route generation device generates one route between the specified pass-through road and the guiding route (37) and extends the specified pass-through road to generate a user-specified road. A user-specified road and the guiding route (37) are connected to generate a renewed guiding route.

1. A guiding route generating device characterized by comprising:
-
storage means for storing a guiding route generated based on specification of a position as a route used in guiding a route; display means for displaying the guiding route stored in the storage means with roads in the periphery of the guiding route; specified route determining means for determining whether the road based on passage specification by a user among the roads displayed with the guiding route is available as a part of a route from a starting point to an ending point of the guiding route or not; generating means for generating an alternative route for a place unavailable of the road if the road specified to pass through by the specified route determining means is determined as unavailable; and updating means for updating a part or the entire of the guiding route stored in the storage means with the route which combines the road determined as available by the specified route determining means and the road of the alternative route generated by the generating means. - View Dependent Claims (2, 3, 4, 5, 6, 7, 8, 9, 10)

11. A guiding route generating device characterized by comprising:
-
storage means for storing a guiding route generated based on specification of a position as a route used in guiding a route; display means for displaying the guiding route stored in the storage means with roads in the periphery of the guiding route; user-specified route generating means for generating a user-specified route which is available as a part of the route from a starting point to an ending point of the guiding route based on passage specification by a user for the road displayed with the guiding route; and intersection determining means for determining whether a route which connects the user-specified route generated by the user-specified route generating means with the guiding route stored in the storage means is regulated for traffic in the direction from a starting point to an ending point of the route that connects said routes at their intersection or not.

12. A guiding route generating method characterized by comprising:
-
a step of displaying a guiding route generated based on specification of a position and stored in a storage means with roads in periphery of the guiding route; a step of determining whether the road based on passage specification by a user among the roads displayed with the guiding route is available as a part of a route from a starting point to an ending point of the guiding route or not; a step of generating an alternative route for a place unavailable if the specified pass-through road is determined as unavailable; and a step of updating the guiding route stored in the storage means with the route which combines the road determined as available and the road for the alternative route.

14. A guiding route generating device characterized by comprising:
-
storage means for storing a guiding route generated based on specification of a position as a route used in guiding a route; display means for displaying the guiding route stored in the storage means with roads in the periphery of the guiding route; specified road specifying means for specifying a predetermined road among the roads displayed with the guiding routes as a specified pass-through road based on a user'"'"'s operation; intersection specifying means for specifying the presence and the number of intersections of the specified pass-through road and the guiding route stored in the storage means; user-specified route generating means for generating two routes between the specified pass-through road and the guiding route and generating a user-specified route which is the specified pass-through road extended with the generated two routes, when the intersection specifying means specifies that there is no intersection, and generating a route between the specified pass-through road and the guiding route and generating a user-specified route which is the specified pass-through road extended with the generated route, when the intersection specifying means specifies only one of the intersections; updated guiding route generating means for generating an updated guiding route by connecting the user-specified route with the guiding route stored in the storage means at their intersections. - View Dependent Claims (15, 16, 17, 18, 19, 20)

21. A guiding route generating method characterized by comprising:
-
a step of displaying a guiding route generated based on specification of a position and stored in a storage means with roads in the periphery of the guiding route; a step of specifying a predetermined road among the toads displayed with the guiding route as a specified pass-through road based on a user operation; a step of specifying the presence and the number of intersections of the specified pass-through road and the guiding route stored in the storage means; a step of generating two routes between the specified pass-through road and the guiding route and generating a user-specified route which is the specified pass-through road extended with the generated two routes, when it is determined as no intersection is present and generating a route between the specified pass-through road and the guiding route and generating a user-specified route which is the specified pass-through road extended with the generated route, when only one of the intersections is identified; and a step of generating updated guiding route by connecting the user-specified route with the guiding route stored in the storage means at their intersections.
