Abstract
The findings of earlier groups which have considered the implementation of traffic restraint are reviewed. Parking charges were Seen as a starting point for restraint but in the long run a system of entry charges or electronic metering would be more likely to be beneficial. The economic principles of marginal congestion pricing are discussed, the effect of environment costs are outlined, and the implications of the wider effects briefly noted. The development of equipment and systems for road pricing at R R L is described.
