SUMMARY
One of the main objectives of the European transport strategy in its 2011 White Paper is to help establish a transport system that enhances competitiveness of European countries. By performing a methodological study, analysing several European transport infrastructure investment cases and conducting a review on various assessment tools, we clarify the relationship between transport infrastructure investment and its wider economic impacts, namely competitiveness and economic growth, we make synthesis of some proposed improvement of the methodology used to assess these impact as well as some recommendations on assessing European Union (EU) policy in transport infrastructure investment in respect of competitiveness and economic growth.
