ABSTRACT:
A method for developing traffic messages for broadcast is disclosed. Data indicating a plurality of traffic conditions on a road network are obtained. For each of the traffic conditions, the data provides a start location at which the traffic condition begins and an end location at which the traffic condition ends. For each of the traffic conditions, a road length from the start location to the end location is determined. The traffic conditions are assigned a priority based upon the road lengths. The data indicating the traffic conditions are transmitted in the assigned priority as a plurality of traffic messages.
