This paper describes the causes of the economical inefficiency of the freight transportation system in Venice, and analyses the problems caused by the damages done by the waves. A properly modified form of road pricing, aiming at improving the efficiency of the traffic chains by introducing the pressure of competition between the freight operators, is thereby conceived and the possible deriving scenarios are described.

Since then the system is running smoothly. Currently the toll applies only to state motorways (the so called Autobahnen) but there are plans to extend it to the secondary level of federal long-distance roads (the Bundesfernstraßen). This paper describes the political and economic background of the introduction of the HGV-toll in Germany. The paper sketches the history of the implementation process, describes the major structural elements of the toll, and discusses current problems and possible future developments. Finally some policy conclusions are drawn.

Empirical results from a survey among Dutch car owners Authors: Ubbels, Barry; Verhoef, Erik Abstract: This paper presents the results from a questionnaire among Dutch car owners. We have analysed the behavioural responses to three different, policy relevant, road pricing measures. Depending on the type of measure and type of trip affected, we find reductions in the number of car trips of, on average, 11%. A flat kilometre charge affects social trips considerably more than commuting trips. However, when policy makers want to affect peak time (commuting) traffic, a time differentiated measure is more appropriate. Slow traffic and trip suppression are most popular alternatives for non-commuting trips. Departure time changes become very attractive for all purposes when the proposed measure varies over time.

The new tunnel is expected to cost more than €1 billion, and tolls have been suggested to help finance construction and to manage demand. This paper conducts a preliminary cost-benefit analysis of a new tunnel and three alternative tolling schemes, and compares them with a do-nothing scenario and an option to toll the existing tunnel without building a new one. The two tunnels are treated as imperfect substitutes, and a multi-year accounting framework is adopted that accounts for emissions, accidents and noise externalities, road damage, revenues accruing to the national and regional governments from existing transport user charges, and the salvage value of the new tunnel. With the base-case parameter values it is found that building the tunnel is worthwhile with all three tolling regimes and yields a higher benefit than not building the tunnel and tolling the old one. Nevertheless, the net benefit from building the tunnel differs appreciably between tolling regimes, and it is sensitive to the value assumed for the marginal cost of public funds.
