A flow travel time relationship based on concepts of the queueing theory is postulated and the level of agreement with measured data is examined. For some transportation planning purposes, a section of road can be sufficiently described purely in terms of the three parameters of the relationship. Its use leads to a more sophisticated approach to the problem of traffic assignment and enables feedback effects to be readily taken into account. It also provides a logical basis for interzonal assignments to more than one road with full capacity restraint. The nature of the relationship also gives rise to suggested more rational definitions of saturation flow rate and practical capacity (A).
