Abstract
A method that facilitates complying with traffic restrictions that involve three or more connected road segments when using a navigation system to determine a route. The method includes forming multiple instances of data representing each intermediate road segment between an entrance segment and an exit segment and storing data defining restrictions that apply to only two connected road segments, such that a valid driving paths exists between the entrance segment and the intermediate segment and between the intermediate segment and the exit segment, but that no valid driving paths exist between the entrance segment and the exit segment.
