One of the immediate impacts of COVID-19 on urban centres has been the significant change in public transport usership as citizens have moved away from public transport into cars, onto bicycles or towards walking as a method of getting from A to B. Whilst some of these shifts may at first appear temporary there is a risk that some of the more negative modal shifts (e.g. into private cars) could linger. A negative shift in public transport attitudes and behaviours of this type could be hugely disruptive to city leaders already struggling to both meet stretching greenhouse gas emissions targets, and improve the experience of citizens who are using city roads.
