NAVIGATION DEVICE & METHOD
First Claim
1. A navigation device operable to generate an output indication representing whether or not journey conditions are favourable, the navigation device comprising a processing resource configured to:
- determine first journey time information for traversing at least one segment of a navigation route at a first predetermined time;
determine second journey time information for traversing said at least one segment of the navigation route at a second predetermined time different from said first predetermined time;
determine from said first and second journey time information a journey time parameter representative of an evolution characteristic of journey time; and
generate, responsive to the journey time parameter, said output indication representing whether or not journey conditions are favourable.

Abstract
A navigation device is disclosed which is operable to generate an output indication representing whether or not journey conditions are favourable. In at least one embodiment, the navigation device includes a processing resource configured to: determine first journey time information for traversing at least one segment of a navigation route at a first predetermined time; determine second journey time information for traversing the one segment of the navigation route at a second predetermined time different from the first predetermined time; determine from the first and second journey time information a journey time parameter representative of an evolution characteristic of journey time; and generate, responsive to the journey time parameter, the output indication representing whether or not journey conditions are favourable.

16. A method of operation of a navigation device for generating an output indication representing whether or not journey conditions are favourable, the method comprising:
-
determining first journey time information for traversing at least one segment of a navigation route at a first predetermined time; determining second journey time information for traversing said at least one segment of the navigation route at a second predetermined time different from said first predetermined time; determining from said first and second journey time information a journey time parameter representative of variation in journey time; and generating the output indication responsive to the journey time parameter. - View Dependent Claims (17, 18, 19, 20, 21, 22, 23)

24. A computer program which, when executed by a processor, implements a method for generating an output indication representing whether or not journey conditions are favourable, the method comprising:
-
determining first journey time information for traversing at least one segment of a navigation route at a first predetermined time; determining second journey time information for traversing said at least one segment of the navigation route at a second predetermined time different from said first predetermined time; determining from said first and second journey time information a journey time parameter representative of variation in journey time; and generating the output indication responsive to the journey time parameter. - View Dependent Claims (25)
