Abstract
A method for developing traffic messages is disclosed. Data indicating traffic speed at a plurality of locations on a road network are obtained. Each of the locations is assigned a unique location reference code. The data indicating traffic speed for the location reference codes assigned to locations along a road of the road network are evaluated. Locations reference codes along the road having related traffic speeds are grouped into at least one congestion event along the road. The congestion events are transmitted as traffic messages.
