First Claim
Patent Images
1. A navigation system comprising:
- a processing resource and an output device for providing a departure time to a user, wherein the processing resource is configured to;
receive destination data representative of a destination;
determine, for each of a plurality of possible routes to the destination, a reliability measure representative of an expected reliability of an expected travel time for the route;
select a route in dependence upon the reliability measures for the routes;
determine an expected travel time to the destination based on the selected route; and
determine the departure time in dependence upon the expected travel time to the destination,the processing resource being further configured to;
receive an indication whether an appointment associated with the destination is of high importance; and
,when the appointment is of high importance, select a route only from amongst routes having a reliability measure above a predetermined threshold.

15. A method of operation of a navigation apparatus comprising:
-
receiving, by a processing resource, destination data representative of a destination at the navigation apparatus; determining, by the processing resource, for each of a plurality of possible routes to the destination, a reliability measure representative of an expected reliability of the expected travel time for the route; selecting, by the processing resource, a route in dependence upon the reliability measures for the routes; determining, by the processing resource, an expected travel time to the destination based on the selected route; determining, by the processing resource, a departure time in dependence upon the expected travel time to the destination; and providing, by the processing resource, the departure time to a user, the method further comprising; receiving, by the processing resource, an indication whether an appointment associated with the destination is of high importance; and
,when the appointment is specified to be of high importance, selecting, by the processing resource, the route only from amongst routes having a reliability measure above a predetermined threshold.

16. A non-transitory computer readable medium comprising computer executable instructions to perform, when executed on a computer, a method of operation of a navigation apparatus comprising:
-
receiving destination data representative of a destination at the navigation apparatus; determining for each of a plurality of possible routes to the destination, a reliability measure representative of an expected reliability of the expected travel time for the route; selecting a route in dependence upon the reliability measures for the routes; determining an expected travel time to the destination based on the selected route; determining a departure time in dependence upon the expected travel time to the destination; and providing the departure time to a user, the method further comprising; receiving an indication whether an appointment associated with the destination is of high importance; and
,when the appointment is specified to be of high importance, selecting the route only from amongst routes having a reliability measure above a predetermined threshold. - View Dependent Claims (17, 18, 19, 20)
