As affluence grows, it gets easier to travel faster and further. But research shows that, despite this, the average travel time in all societies remains steady at roughly an hour a day. The implication is that people are choosing to increase the distance they regularly travel, rather than opting for shorter journey times. While this clearly offers advantages in terms of reaching more desirable locations, the disadvantages are numerous - not least that of anthropogenic climate change, to which transport is the fastest growing contributor. However, the stability of travel time does not form...

Britain does not have a coherent transport policy, and conventional transport economics has reached a dead end. A transport policy should incorporate systematic thinking about the travel needs of society. However, in Britain, public investment in the transport system has been extraordinarily volatile. We closed under-used railways and then experienced a doubling of passenger numbers that has prompted huge new investment. We gave up making substantial investment in motorways, but now have chosen to revive the road construction effort in a big way. We vacillate on road pricing, introducing...

Travel is central to our lives, and the transport system brings us the goods and services that we need and allows us to access the experiences and opportunities that we seek. Yet our transport system has many problems: congestion and overcrowding, noise, air pollution and carbon emissions, deaths and injuries, and the intrusion of vehicles into unsuitable locations. Much effort and money has been devoted to tackling these problems, over many years, but progress is slow. Recognition of the urgent need to respond to climate change is prompting major transport developments - particularly a...
