Patent

CA 2257438

A system for periodically transmitting traffic speed data files in a graphical format over Digital Audio Broadcasting channels is disclosed. The traffic speed data files are fused from a plurality of raw traffic data streams related to different road sections. Also broadcast, but less frequently, are background road map files in a raster image format which, when received with the traffic speed data files in a display terminal, provide a colour-coded road map showing different traffic speeds in different road sections. Additional weather and tourism information can be combined with the traffic data for presentation of a common display (on different zones and pages) at the receiving end.
