Abstract
Dutch policy looks upon the realisation of the transferium concept as one of the instruments to control the growth of car use. A transferium can be defined as a Park and Ride (P+R) lot which has extra facilities. When planning and designing transferia, it is therefore relevant to research the current P+R usage. In this study a number of P+R lots were researched at week-days and at the week-end. A distinction was made between public transport users and users of P+R with other motives. Also, non-P+R users were sent a questionnaire. As a result of the study a number of recommendations is presented.
