Samenvatting
In the absence of congestion road pricing, the equilibrating mechanism that emerges in the city, is congested peak hour operation on the road system. This surrogate price mechanism is an essential feature of the dynamic system and should be recognised and included in the planning logic. It is an aspect of system functioning and not evidence of system failure. Acceptance of this philosophy modifies some of the traditional articles of faith in urban traffic engineering and road planning. A discussion is added.
