The relationship between speed, flow and density of a highway traffic stream

  • R. J. Salter


Theoretical relationships between speed, flow and density When 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.
