Travel behaviour has evolved in unexpected ways in urbanised areas in the early 21st century. This report examines how significant breaks with past trends happened - and why these shifts were not foreseen. The Covid-19 pandemic adds to uncertainty about future demand to travel. Forecast-led transport planning is not well equipped to handle uncertainty. The report presents new approaches which explicitly address uncertainty, are vision-led and enable the development of resilient plans. It also considers how governance and institutions can be adapted to support such a paradigm shift.
