The weight of each route is defined as the ratio of loaded/empty containers traffic volume along this route to the total volume of transported containers for the accounting period.

As additional instruments to ERAI, two sub-indices have been created - ERAI U West and ERAI U East, which reflect the cost of 1 FEU transportation on Asia-Europe or Europe-Asia route respectively. ERAI as well as the sub-indices (ERAI U West and ERAI U East) constitute the hierarchical system of the Index, which currently has two levels.
Thus, ERAI is a comprehensive composite indicator reflecting the current state of the container railway transportation market and can be applied as an instrument for analytics and marketing research. ERAI U West and ERAI U East sub-indices, in turn, reflect the weighted average transportation cost on the definite routes (Asia-Europe or Europe-Asia) and can be applied in determining the value of contracts for containers transit transportation.
