Samenvatting
This paper tries to systematically classify methods of providing public transport in urban areas. Eight main groups of transport system are classified: (1) continuous systems (conveyor); (2) controlled autonomous systems (metro, monorail); (3) controlled not-autonomous guided systems (urban tram, combined bus-service); (4) controlled non-guided systems (bus); (5) demand-dependent autonomous systems (people mover, cabin lift); (6) demand-dependent non-guided systems (bel bus, bustaxi, shared taxi); (7) individual autonomous systems (cabin taxi); and (8) individual non-guided systems (taxi).
