NAVIGATION DEVICE & METHOD

摘要

A navigation device (200) operable to generate an output indication representing whether or not journey conditions are favourable, the navigation device comprising a processing resource configured to: determine (660, 661) first journey time information for traversing at least one segment of a navigation route at a first predetermined time; determine (662, 663, 664) 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 (666) 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.
