The latest update of annual transport infrastructure investment and maintenance data collected by the International Transport Forum at the OECD shows that for the last 15 years:

• Investment in inland transport infrastructure has remained constant at 0.8% of GDP for the OECD (excluding Japan) and the volume of investment has grown 30%; 
• In North America and Western Europe the GDP shares for investments in road, rail and inland waterways are constant, whereas in many developing and transition economies transport investment as a share of GDP is increasing; 
• Western European economies have invested increasingly in rail while in Central and Eastern European countries the focus is on roads; 
• While record investment levels were reached in Central and Eastern European countries in 2009, the latest data show decline for the first time (-11% in real terms in 2010).
