According to this report, transport infrastructure investment is projected to increase at an average annual rate of about 5% worldwide over the period of 2014 to 2025. Sub-Saharan Africa leads the pack with the fastest average annual growth rate of over 11%. Meanwhile, Asia-Pacific remains by far the largest transport infrastructure market, with investments increasing from $557bn per year to nearly $900bn per year in 2025. On the downside, transport infrastructure investment levels in Western Europe are expected to take a long time to recover due to continual fiscal austerity – returning only to 2008 levels in 2022.
