This special issue of RSPP focuses on Covid-19, transport and mobility. It includes 10 original research papers that address the linkages between transport and mobility on the one hand and Covid-19 on the other. They can be categorized into three groups. The first group deals with the impact of mobility on the spread of Covid-19 (contributions 1 & 2). The second group analyses the opposite effect of Covid-19 on mobility behaviour and transport supply (contributions 3, 4, 5, 6 & 7). The third group focuses on the particular effect of the use of digital technology through teleworking or e-commerce practices (8, 9 & 10).
