Infrastructure and transportation in the twenty-first century–ever-increasing circles?

Understanding and controlling travel demand is one of the great challenges for the twenty-first century. This paper has been prepared in the wake of the first UK Transport White Paper for some 20 years which has sought to reconcile a multitude of requirements that society has from transport. The paper does not offer an alternative White Paper but aims to highlight the key themes that will shape the future of transport and to propose options and visions for the twenty-first century. In so doing, the intention is to deliver some fresh thinking into the transport debate that will serve as a catalyst for future, perhaps fruitful, discussion.
