Abstract

There is provided a navigation device, the navigation device operable to calculate routes to one or more destinations, the device further operable to provide a navigation instruction together with an alternative navigation instruction. There is also provided a method of providing navigation instructions for a navigation device, the method comprising the steps of (i) calculating routes to one or more destinations, (ii) providing a navigation instruction together with an alternative navigation instruction. There is also provided a computer program product operable to execute on a navigation device, the computer program product operable to calculate routes to one or more destinations, the computer program product further operable to provide a navigation instruction together with an alternative navigation instruction.

Claims

1. A navigation device, the navigation device operable to calculate routes to one or more destinations, the device further operable to provide a navigation instruction together with an alternative navigation instruction.

2. The navigation device of claim 1, wherein the device is operable to provide a navigation instruction and an alternative navigation instruction without user intervention.

3. The navigation device of claim 1, wherein the device provides an alternative route without a user being required to request a calculation of an alternative route.

4. The navigation device of claim 1, the device comprising a screen, the device displaying on the screen a navigation instruction and an alternative navigation instruction simultaneously.

8. The navigation device of claim 1, wherein the device provides an alternative route advice that deviates from the route that the driver normally drives.

9. The navigation device of claim 1, wherein the device provides an alternative route advice and shows an original advice as well, augmented with a difference in distance and travel time.

10. The navigation device of claim 1, wherein the device provides an alternative advice for a route to or via a nearest parking or rest area.

11. The navigation device of claim 1, wherein the device provides an alternative advice for a route to or via a nearby fuel station.

14. The navigation device of claim 1, wherein a verbosity of alternative advices is configurable.

15. The navigation device of claim 1, wherein alternative advices are configurable to be augmented with a difference in at least one of length and time.

17. The navigation device of claim 1, wherein the device is such that if a driver follows an alternative advice which is part of an alternative route, rather than continuing with the main route, the device considers the alternative route associated with that alternative advice to be the new main route.

20. The navigation device of claim 1, wherein alternative advice is identified because it has a different colour, or a different background colour, or a different style, or a different location on a screen.

24. The navigation device of claim 1, wherein the device receives traffic information.

25. The navigation device of claim 24, wherein an alternative route is computed by considering what would be a best route if there were no traffic, but then computing an actual travel time required for that best route in view of traffic.

26. The navigation device of claim 1, wherein information about an alternative route is displayed as a modified road sign.

28. The navigation device of claim 1, wherein the device can be programmed with a map database and software that enables a route to be planned to a destination.

30. The navigation device of claim 1, wherein the device is selected from the group consisting of:

a portable device, an in-built vehicle device, a device designed for non-vehicle use, and a device designed for vehicles other than cars.
