Road pricing (tolls, etc.) as a means of generating revenue for infrastructure investment has become a major policy option in both Europe and North America. It can also be used as a policy in the management of traffic demand and flow, environmental objectives, and optimal resource allocation as regards the size of investments. Road pricing is assumed to be able to solve many problems simultaneously -- congestion control, pollution reduction, and investment financing. This volume assembles and assesses theoretical knowledge, empirical results and experiences of actual road pricing. In addition, the impact of new information technology on future policy formulation is considered.
