The distribution of vehicular speeds in a highway traffic stream

  • R. J. Salter


One of the fundamental parameters for describing traffic flow is the speed, either of individual vehicles or of the traffic stream. It is of importance in work connected with the theory of traffic flow because of the fundamental connection between speed, flow and concentration when the movement of a traffic stream is being considered.
