Abstract

A computer-implemented method of displaying traffic conditions on a road system includes creating a 3D graphical map of the road system that includes one or more segments. The status of at least one of the segments on the 3D graphical map is determined. The status of the segment corresponds to traffic data associated with that segment. A 3D model of the road system is created by combining the 3D graphical map and the status of that segment.
