Does traffic really disappear when roads are closed?

Abstract

This paper describes two studies that aimed to explore the impacts of pedestrianisation or road closures on traffic displacement, travel behaviour and the phenomenon of ‘disappearing traffic’. The first study surveyed residents whose travel routes were affected by a small-scale localised pedestrianisation scheme in the centre of a town. The second measured the traffic impacts of a temporary closure of a strategic bridge in a city centre. In the first case, the pedestrianisation produced no change in the modal shares of travel of residents. Drivers continued to drive to the same locations by longer routes. In the second case, the closure caused some traffic displacement and increased journey times but also reduced traffic volumes in both the immediate area and across the city. This paper concludes by discussing the remaining knowledge gaps on disappearing traffic, made more pressing by the decisions of authorities to reallocate road space during the coronavirus disease 2019 crisis.
