Travel is the movement of individuals between different distant geographic locations. Travel can be to a local destination or to another location that is quite a distance away. Travel can also be one-way or round-trip, and may be either public or private. It can also take place by land, sea or air.
Travel has taken many shapes and forms through history. A simple definition of travel is the travel of one’s self. If we want to define travel as a single kind of movement, then we could say that the first journey was a single journey, then repeated, now we have buses, planes, trains and automobiles, so what is there left for the travel of the self? Perhaps nothing, but this question begs the next one – what about travel between places?
To define travel as a means of human interaction within geographical boundaries and in between these boundaries is not too difficult. For example, travelling from Paris to London by train is not really a journey, it is a circuit around the edge of Paris and London and back again. To define travel on a more global scale, there are no fixed boundaries where one ends and another begins, it is simply a circuit of travelling. The same principle applies to travelling by road or by air.
