Abstract
A system and method for displaying traffic information in an automotive navigation system having a display, memory and a data receiver. The method includes the first step of storing in a traffic speed table in memory at least two speed threshold limits wherein each speed threshold limit represents a different traffic flow category. The receiver receives data representative of the vehicle speed on at least one road segment and compares that received vehicle speed data with the traffic speed table to determine the traffic flow category corresponding to the received speed data for the road segment. A visual indicator is then displayed on the display which corresponds to the traffic flow category for the road segment. The user is able to customize the speed threshold limits through a GUI. These speed threshold limits are further user modifiable as a function of weather, day of the week, road conditions, type of road, as well as other factors.
