Transport telematics in urban systems - A backcasting Delphi study

This paper includes a presentation of the results from a scenario study on transport telematics in urban passenger transport. An international Delphi panel of 100 experts from 20 countries replied to questions on the feasibil ity and impact of a restricted number of different technical scenarios. The results show that most experts see substantial potential for limiting cert ain transport problems if there is broad implementation of transport telema tics as described in this study. The majority of experts favoured a scenari o based on extended public transport information. In that scenario, environ mental gains were in practice paid for in terms of less comfortable trips a nd longer travel times. (C) 1998 Elsevier Science Ltd. All rights reserved.
