The co-modality is a notion introduced by the European commission in 2006 in the field of the transport policy to define an approach of the globality of the transport modes and of their combinations. For the European commission the co-modality refers to a "use of different modes on their own and in combination" in the aim to obtain "an optimal and sustainable utilisation of resources".

 

This notion introduces a new approach to the European transport policy in which one do not seek, like in the 2001 white paper, to oppose transport modes one to another, i.e. opposing roads to its alternatives, but rather to find an optimum exploiting the domains of relevance of the various transport modes and of their combinations.
