The Transport Research Arena (TRA) is the foremost European transport event that covers all transport modes and all aspects of mobility. Occurring biennially, it attracts 3,000 attendees from all over Europe and beyond. TRA2020 was planned to take place in Helsinki on 27–30 April on the theme “Rethinking transport – towards clean and inclusive mobility”. For the first time a Journal review track was organised, and the 20 best research papers published in a Special Issue in ETRR. Despite the Conference being cancelled due to the COVID-19 pandemic, we are pleased to announce that the valuable scientific work from the Conference is still available in this Special Issue.
