The evaluation of the TEN-T guidelines will address pre-defined questions on relevance, effectiveness, efficiency, EU-added value and coherence with other EU policy areas. Efficient, safe, smart and sustainable transport abreast with the challenges of climate change and digitalisation is enabled by a strong TEN-T. The evaluation will therefore take account of the progress made since its entry into force in relevant areas, e.g. on alternative fuel for transport, multi-modality or digitalisation.
