ULTra (Urban
Rapid Transit) is a Personal Rapid Transit (PRT) system for Heathrow Airport.
The pod-car
system was developed by a British engineering company called Ultra Global PRT. The pod-cars use
four car batteries as they don’t have any engines; they use 50% less energy
than a bus does, are driverless, computer driven and are guided by lasers on an
open guideway; they also charge automatically at the charging points and instead
of rails, they use rubber tyres.
