ABSTRACT
Humans, throughout our history, have continuously searched for new ways to facilitate movement, travel, and transportation to survive, but also to improve quality of life. Nowadays, as distance becomes less critical thanks to continuous advances in communications and transport technologies, more and more people proceed into urban and interurban traveling for business, leisure, socialization, entertainment, and education. For example, we move from one location to another to get to work, to attend a business meeting, to visit a museum or a friend in another city or country, for shopping, and so on. Clearly, mobility, the ability and willingness to move by means of self-powered motion (e.g., walking) or transportation, is a basic facilitator toward autonomous living and social inclusion.
