It is organised around four main areas:

• • Contributing to spatial planning by planning and financing the construction of railway, public
    transport, river and port infrastructures;
  • Participating in improving security and safety for all land and sea transport activities;
  • Contributing to achieving a balance between the various modes of transport;
  • Helping to develop other modes of transport as alternative to road transport;
  • Guaranteeing compliance with technical, economic, and social rules in a transport market, which is
    deregulated at European level, by drafting regulations and regulating the market.

The DGITM conducts certain of its missions in partnership with major public companies falling under
its authority, such as Réseau ferré de France or Voies navigables de France which construct and
manage infrastructures or the SNCF and the RATP which provide transport services.

The DGITM contributes to the government’s action at regional level thanks to the privileged relationship
it maintains with the decentralised departments (regional Infrastructure and Maritime Affairs directorates,
maritime departments within the departmental Infrastructure directorates, etc.).
