Abstract

After a user inputs a source, a destination and preferences, many different routes will be generated accordingly. Some of the routes may have shorter estimated traveling times, some of the routes may have shorter traveling distances, but other routes may make use of freeways. Different kinds of routes can be indicated simultaneously and thus the user can choose an optimal route perceived by the user from the generated routes.

Claims

1. A route-inquiry method comprising:

generating a plurality of feasible routes according to a source and a destination; and

indicating the plurality of feasible routes simultaneously.

2. The method of claim 1 further comprising selecting a route from the plurality of feasible routes.

3. The method of claim 1 further comprising inputting the destination.

4. The method of claim 3 further comprising inputting the source.

5. The method of claim 3 further comprising detecting the source through a Global Positioning System (GPS).
