Abstract:

Systems and methods are disclosed for generating and displaying a linear visual indicator of an entire route on a singular screen. One method includes calculating a route based on start and destination location and then determining various conditions along the calculated route. These conditions include, for example, traffic, weather, construction, road type, etc. This discloses generating and displaying a linear depiction of the full route and the navigation mapping screen, to provide the user with an easily understandable and accessible view of the full picture of route conditions.
