Following discussions about the need to update the methodology for the identification of bottlenecks and missing links adopted by the Inland Transport Committee in the early 1990s, government delegates in the UNECE Working Party on Transport Trends and Economics agreed to commission a new report on this topic. An informal group of experts supported by the UNECE secretariat guided Professor Alan Pearman of the University of Leeds in the preparation of the report. The UNECE Working Party on Transport Trends and Economics adopted this report at its twenty-first session (9-10 September 2008).

The revised methodology for the identification of bottlenecks, missing links and quality of service in infrastructure networks will facilitate a coherent appraisal and selection of transport infrastructure projects of international importance across the UNECE region.
