With all but essential travel restricted, walking and cycling have emerged as vital forms of mobility during the COVID-19 crisis. These are physically-distant, active, equitable and low-carbon transport modes which are helping to facilitate safe essential shopping and exercise, and alleviate pressure on public transport for essential workers. There has also been an uptick in food and other deliveries by bike, cargo, e-bike and e-cargo modes. As cities plan how to sustainably live with the virus in the medium-longer term, increased walking and cycling will be critical to enable more people to travel safely and efficiently around their cities. Investment in walking and cycling now, while streets are quiet and traffic is reduced, will also quickly deliver a raft of other benefits for local economies as well as improvements in air pollution, equity and more.
