Effecten van de invoering van de studentenkaart : doel, opzet en veldwerkresultaten.

On January 1, 1991 the Public Transport Pass for students had been introduced. All students aged between 18 and 27 who receive a government grant also receive a public transport pass. The pass is valid throughout the whole country for all means of transport. This paper describes the objectives of the study, the research programme and gives some results of the fieldwork which has been carried out.
