This volume addresses key contemporary aspects in cycling policy, practice and research. Cycling has seen a sharp increase in scientific and policy attention in the past decade. The amount of research has surged over the past couple decades. Also, levels of cycling have increased substantially in many countries and cities, and many areas have seen increases in infrastructure investments. In addition, the last decade has seen innovations in bicycle technology, in particularly the rise of electric-assist (e-bikes) and dock-less bike sharing schemes. This volume reviews the state of the art on cycling from various angles. As such it explores planners' (engineers', policy makers') provisions for cycling, of cyclists' (and non-cyclists') travel behaviour, and resulting consequences for individuals and society. One focus is on demand-side aspects, including the use of bicycles and their users including patterns and trends in cycling, determinants of cycling, and modelling of cycling. Another focus is on impacts of cycling, such as emissions, safety aspects, as well as changes during the COVID pandemic. - Contemporary overview of key aspects in cycling research and bicycle planning - A focus on design for cycling, behavior of cyclists and consequences of cycling
