Transport geography

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 space.The goal of transportation is thus to transform the geographical attributes of freight, people or information, from an origin to a destination, conferring them an added value in the process. The convenience at which this can be done - transportability - varies considerably. The specific purpose of transportation is to fulfill a demand for mobility, since transportation can only exists if it moves people, freight and information around. Otherwise it has no purpose.Any movement must thus consider its geographical setting which in turn is linked to spatial flows and their patterns.
