The ERIM Project, carried out in 2004-2007, has been based on a detailed database on main international corridors, mainly for freight, between 32 countries.
The ERIM database is constituted of about 50,000 route-km divided into 1,100 interconnected line sections enabling the corridors to be redefined to suit any particular business or political configuration.
The main areas covered by the database are:
Current and planned 2020 infrastructure provision (including detailed investment plans).
Estimations on current and 2020 traffic volumes
Estimations on current and 2020 capacity utilisation
The ERIM database will be updated regularly and the UIC Atlas of Infrastructure in the ERIM Network will be published on a yearly basis.
