Samenvatting
This paper deals with the issue of substitution between car and public transport. The emphasis is on two questions: (1) why do improvements of the public transport system attract so few car users, at least on a national scale? (2) why do so few car users switch to public transport in response to so called 'push' measures? The answers to these questions presented in this paper amount to one common aspect; there are still too many spatial relations where the public transport supply is not a competitive alternative with respect to time, place and character among all the available alternatives for travel behaviour.
