Road traffic is expected to double by the year 2025. Everybody agrees that growth of this order is unsustainable, whether in terms of atmospheric pollution or of available road space. Unless the onward march of motor car and lorry can be checked, or at least slowed, a small, crowded islandsuch as Britain faces an intolerable decline in air quality and the threat of national gridlock.In this timely book, leading experts in the fields of transport, land use and the environment analyse the problem and discuss possible solutions to it. Can cars and lorries be made `cleaner'? How can private motorists be weaned from their love affair with the car? Should we build more motorways?Or should road space actually be reduced? How serious is the pollution caused by shipping and aircraft? What will be the impact of the Channel Tunnel? These are some of the questions addressed, concisely and with authority, in this challenging book.
