1. A computer-implemented method of displaying traffic flow data on a graphical map of a road system, the graphical map including one or more segments, the traffic flow data representing traffic conditions on a road system, the method comprising: (a) determining a status of each segment on the graphical map, the status corresponding to the traffic flow data associated with that segment; (b) creating an animated traffic flow map of the road system by combining the graphical map and the status of each segment, wherein the animated traffic flow map is created by being continuously rendered in real time; and (c) updating the traffic flow data in real-time, the traffic flow map immediately reflecting the updated traffic flow data.
