OPTIMAL LOCATIONS FOR ROAD PRICING CORDONS

Although alternative technologies are being developed, it is clear that road pricing systems in the immediate future will continue to be cordon-based, with charges to pass points in the road network, or to use vehicles within such cordons. Evidence from a number of studies indicates that the performance of road pricing schemes, in reducing congestion and enhancing the environment, is critically dependent on the design and location of the cordon. In some cases, benefits have been reduced by 20% or more by inappropriate locations, particularly as a result of re-routeing to avoid the cordon. At the same time, the cost of relocating charging points is suhstantial, making it important that the optimal locations are identified initially. This paper reports on the work being conducted in a study, funded by the UK Engineering and Physical Sciences Research Council (ESPRC) to develop improved methods of identifying optimal cordon locations. The methodology has been developed from two sources: a review of the practical and judgmental considerations in determining cordon locations; and a mathematical approach which both determines the best set of links to charge in a network and specifies the optimal charges at each. The paper first discusses the judgmental approach, briefly describes the theoretical approach and displays the theoretical approach for a simple network. It then draws brief conclusions.
