The GTMO 5+5 Multimodal Network of Transport Infrastructures in the Western Mediterranean is made up of the  infrastructures that handle the main transport flows. It also provides a conceptual base for planning and analysing.

In the five European countries in the Group, the GTMO 5+5 Multimodal Network is the equivalent to the Trans-European Transport Network (TEN-T).

The process of definition of the network in the Maghreb countries reproduces the methodology defined for the development of the TEN-T. This procedure guarantees  the internal coherence of the GTMO 5+5 Multimodal Network.

The GTMO 5+5 Multimodal Network of Transport Infrastructures contains a infrastructure network organized hierachically. Their components are the multimodal corridors, the Core network and the Comprehensive network.

The trans-Maghreb corridor  is the backbone of the transport exchanges across the Maghreb. At the same time, the  trans-Maghreb corridor  is the basis for the connection with the Multimodal TEN- Corridors in Western Mediterranean. All this corridors are the main components of the network of transport infrastructures in the Western Mediterranean.

The core network  contains the most strategically important nodes and links that ensure the main flows. Therefore, it ensures the connection among the main cities, ports and airports and provides access to peripherical areas.
