Travel demand exhibits a long coevolution with technological development, both directly, in response to the invention of new transport systems, and indirectly, as a result of transport aspirations being influenced by innovations in other sectors, such as the invention of the telephone and the diffusion of refrigeration.

The development of information-communication technologies in recent decades is central to this theme, having triggered a further round of interactions. New developments have enhanced our ability to manage and interact with the transport system in real-time, and in some cases, offer the prospect of avoiding travelling at all.
