This report is the first in a series of eight to be produced by the Transport Visions Network. The Network was established in November 1999 by the transportation Research Group of University of Southampton with support from the EPSRC, the Rees Jeffreys Road Fund and the DETR. The Network involves young professionals aged 35 and under from academia, consultancy and government. It operates through the process of structured email and face to face discussions in exploring the future of transport in the 21st century. The Network aims to challenge existing mindsets regarding transport and thereby ensure more robust and informed perspectives are available to key decision makers This report recognises that changes in the fabric of society and its set values can have a profound impact on travel demand and transport. Transport professionals must be mindful of the outward integration of transport with employment, business practices, standard of living, households, education, social values etc. as well as awareness regarding the diversity of factors that will directly or indirectly influence future travel demand.
