The International Transport Forum (ITF) organised with great success the 2021 ITF Summit which was held online, on 17-28 May. ITF’s research unit supported the Summit with topical analyses and a pre-summit Research Day was organised with leading institutions to provide cutting-edge academic input to the Summit debate. Side events hosted by ITF partner organisations took place in and around the Summit thereby allowing greater opportunities for presentations of recent work and dialogue on key issues complementing the Summit theme.
