The changes in the number of transport PPI projects by geographic regions in the 1991-2018
period are presented in Figure 26. In terms of using PPI models in transport projects, South Asia
- with an increasing trend in recent years - and Latin America and the Caribbean are the two
best performing regions whereas Middle East and North Africa and Sub-Saharan Africa
remained at the bottom of the figure. Another interesting feature of the figure is its fluctuant
pattern as a result of regional and global crises which proves that PPI/PPP implementation has
been quite sensitive to economic stability.

shares of 27.3%, 11.7%, and 9.4%, respectively. Table 17 provides the global transport PPI
project counts and their respective shares with regard to transport modes.
