Abstract
A computer-implemented method is provided for displaying on a graphical map traffic flow data representing traffic conditions on a road system. The graphical map includes one or more keyroutes, each keyroute being defined by one or more contiguous road segments. Congestion status of the one or more keyroutes are displayed on the graphical map. The congestion status is defined by partitioning the keyroute into one or more congestion segments, each congestion segment being defined in terms of a percentage range of the keyroute from the start of the keyroute. Each congestion segment has a congestion status. Also, a plurality of identification objects are shown at fixed positions in the graphical map and a plurality of different views of the graphical map are defined. Each identification object is coded to be either displayed or not displayed for each of the different views. Also, for a selected keyroute, a single display screen displays keyroute identifying information, and the real-time status of the keyroute, wherein the status is continuously updated on the single display screen.
