This introduction presents an overview of the key concepts discussed in the subsequent chapters of this book. The book addresses gender in relation to the various ideas and practices of smart mobilities and sustainable mobility for all. This includes the importance of sustainable and gender-fair development in mobility and transport, which has so far been neglected in research and policy making all over the globe. Gender and diversity are perspectives which thus far have been marginal in the research, design, and planning of smart mobility. Mobility is a key element in the formation of well-functioning societies. While transport is an asset on both individual and societal levels, it contains a series of serious externalities. Smart mobility in its various meanings is said to hold the solution to some of these problems by facilitating the aims of curbing pollution, reducing traffic congestion, and noise and travel costs, along with increasing safety and transfer speed.
