Abstract
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 feasibility and impact of a restricted number of different technical scenarios. The results show that most experts see substantial potential for limiting certain transport problems if there is broad implementation of transport telematics as described in this study. The majority of experts favoured a scenario based on extended public transport information. In that scenario, environmental gains were in practice paid for in terms of less comfortable trips and longer travel times. (Author/publisher).
