THE GEOGRAPHY OF TRANSPORT SYSTEMS

Economic development is linked with transitions in passenger mobility from non-motorized (mainly walking) to motorized forms of transportation. The initial stage of this transition involves the development of collective forms of transportation (tramways, subways, buses) while individual forms of transportation (mainly the automobile) become more prevalent at a later stage. This is particularly linked with the growth of individual incomes where at some point individual motorized mobility becomes affordable. While in developed countries this transition took place over several decades, if not a century, many developing countries are experiencing a fast mobility transition, which is placing pressures on the transport system to cope.
