OECD/ITF Joint Transport Research Centre Discussion Papers

The International Transport Forum at the OECD is an intergovernmental organisation with 52 member countries. It acts as a strategic think tank for transport policy and organizes an annual summit of ministers. Our work is underpinned by economic research, statistics collection and policy analysis, often undertaken in collaboration with many of the world's leading research figures in academia, business and government. This series of Discussion Papers is intended to disseminate the International Transport Forum’s research findings rapidly among specialists in the field concerned.
