Transport geography is a sub-discipline of geography concerned about the mobility of people, freight and information and its spatial organization considering attributes and constraints related to the origin, destination, extent, nature and purpose of movements.

The unique purpose of transportation is to overcome space, which is shaped by a variety of human and physical constraints such as distance, time, administrative divisions and topography. Jointly, they confer a friction to any movement, commonly known as the friction of distance (or friction of space). In an ideal world, transportation would come at no effort in terms of cost and time and would have unlimited capacity and spatial reach. Under such circumstances, geography would not matter. In the real world, however, geography can be a significant constraint to transport since it trades space for time and money and can only be partially circumscribed. The extent to which this is done has a cost that varies greatly according to factors such as the length of the trip, the capacity of modes and infrastructures and the nature of what is being transported. Transport geography can be understood from a series of core principles:

  • Transportation is the spatial linking of a derived demand.
  • Distance is a relative concept involving space, time and effort.
  • Space is at the same time the generator, support and a constraint for mobility.
  • The relation between space and time can converge or diverge.
  • A location can be central, where it generates and attract traffic, or an intermediate element where traffic transits through.
  • To overcome geography, transportation must consume space.
  • Transportation seeks massification but is constrained by atomization.
  • Velocity is a modal, intermodal and managerial effort.
