Samenvatting
Functionalism started with primary land use planning; the resulting needs for vehicular traffic were initially satisfied by mass transport systems. Then the increase in car traffic transforms transport into an autonomous partial area of society which influences settlement development and has numerous consequences. A high degree of specialization dominates the partial area of "transport" today but the meticulous research into subsystems is carried out purely reactively and measures remain rather ineffectual as far as the overall system is concerned.
