Abstract
The relationships considered in chapter 13 between speed, flow and density of a traffic stream considered traffic flow in a microscopic sense in that the 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.
