The Corridor Performance Measurement and Monitoring (CPMM) mechanism is an empirical tool designed by the Central Asia Regional Economic Cooperation (CAREC) Program to assess the efficiency of its six priority transport corridors, which link the region’s key economic hubs and connect landlocked CAREC countries to Eurasian and global markets. The CPMM aims to (i) identify the causes of delay and unnecessary cost to cargo moving along the links and nodes of each CAREC corridor, including at border-crossing points (BCPs) and intermediate stops; (ii) help national CAREC authorities determine how to address identified bottlenecks; and (iii) assess the impact of regional cooperation initiatives implemented along the CAREC corridors by member countries. The CPMM evaluates a set of trade facilitation indicators to illustrate the overall annual performance and efficiency of the CAREC corridors. Measured over time and across corridors, the indicators provide a comparative picture that allows the assessment and validation of impacts of transport and trade initiatives in the region.
