The ULTra (Urban Light Transport) is being developed by the British company Advanced Transport Systems (ATS), and it works on the concept of on-demand personal transport. The system proposes virtually no waiting time to take individual passengers non-stop to their chosen destination. A fleet of driverless electric vehicles, running on a network of elevated or ground level guided routes ferry passengers to their desired destination. The low-floor vehicles have a seating capacity of four, with some additional standing room or space for a wheelchair. The speed maxes to about 40 kilometers per hour hence the non-stop service can make trip times two or three times faster than other urban transport. Passengers can opt for routes and make payments via a smartcard. The passenger destination is passed to central control, which in turn sends the nearest available vehicle in the network to the station. Previous simulations demonstrate that waiting times average around 10 seconds.

The first ULTra (Urban Light Transport) system is actually under construction at the moment at Heathrow airport in London. It will be operable in the fall of 2008. A Dutch company has also recently signed an agreement to introduce ULTra in the Netherlands and Belgium.
