The trans-European transport networks (TEN-T) include 30 priority projects, which are predicted to cost €225 billion. The White Paper European Transport Policy for 2010: Time to Decide raises the difficulty of mobilising capital as one of the main obstacles to carrying out infrastructure projects. Recent EU research projects have covered optimal pricing of existing infrastructure and good use of transport revenue in the presence of social marginal cost pricing. In this project the emphasis is placed on optimal charging and investment to fund new infrastructure. The principal aim of the FUNDING research project is to develop a scientifically sound approach to the funding of large transport infrastructure investments in the EU. Two different avenues are explored for the funding of these investments. The first is the creation of an EU transport infrastructure fund financed by mark-ups on transport activities. The second is the use of mark-ups on the users’ costs charged by the infrastructure suppliers that make the investment.
