Tech foresees future of London travel

This is a virtual transport-ticket seller. She asks visitors if they have enough carbon credits to pay for a journey, suggesting that in the future your travel may be limited by your carbon footprint.

The London 2055 exhibit — sponsored by Orange — allows visitor to see how the future of transport might shape London.

The red unit asks visitors questions about their current lifestyle and travel behaviour and then shows the impact these could have in London over the next 50 years.

They answer the questions via a touchscreen, creating various scenarios.

The exhibit arrives at four different London scenarios in 2055. This one is the "carbon-controlled" scenario.

This is the "local living" vision, in which people will live in simple urban colonies and rely on local resources.

A London bus has been converted to a first-aid centre, and people are depicted as relying heavily on bikes.

This is part of the New York urban transport system, with the various metro and train routes shown and screens picturing people using the modes of transport.

The video footage was partly collected through a request for content on social-networking site Facebook.

It's not all about the future and new technology, though. Here are three London buses through the ages, with the classic Routemaster in the centre.
