A NEW STUDY OF THE TRAFFIC FLOW-CONCENTRATION RELATIONSHIP

A generalised equation relating the traffic flow to concentration is derived. The equation, which leads to a new definition of traffic congestion detectable through the measurement of average vehicle speed or concentration, may be used in on-line traffic control systems. (A) /TRRL/
