The macroscopic determination of speed and flow of a highway traffic streamthe speeds of, and headways between, individual vehicles have been used to obtain relationships for the whole traffic stream. An alternative approach to the determination of speed/flow relationships is the use of macroscopic relationships obtained by the observation of stream behaviour.

The relationship between speed, flow and density of a highway traffic streamWhen considering the flow of traffic along a highway three descriptors are of considerable significance. They are the speed and the density or concentration, which describe the quality of service experienced by the stream; and the flow or volume, which measures the quantity of the stream and the demand on the highway facility.
