Regulation (EU) 1315/2013 on Union Guidelines for the development of the trans-European transport network (TEN-T) governs the EU policy on transport infrastructure. This policy notably aims at facilitating transport flows across Member States and supporting territorial, economic and social cohesion. In line with the Action Plan included in the Commission's Communication on the European Green Deal, and the Sustainable and Smart Mobility Strategy, a proposal for a revision of the TEN-T Regulation is planned in 2021. This consultation forms part of the impact assessment that will underpin the legislative proposal for a revised TEN-T Regulation.The objective of this consultation is to ensure that, in addition to the organisations directly involved in the TEN-T policy, other stakeholder groups and the general public are provided with the possibility to express their opinion about the topic.
