Personal rapid transit systems (=PRT) could be the future for ecological cities reducing pollution while displacing all presently used transportation.

Operating on a widespread network of guideways and working on demand it combines the sustainability of public transportation with the comfort of individual available vehicles. PRT systems need up to four times less energy than automobiles and are less noisy than any other vehicles. Waiting times of a few seconds and non-stop travel to a chosen destination guarantees a movement through the city that is at least two times faster than todays forms of scheduled route services.
In Uppsala, Sweden a test track is proving that PRT systems are more than just a vision. This year a pilot project manufactured by ULTra will be opened at the Heathrow Airport in London for daily transportation of visitors across the airport's territory. Most convincing though is perhaps that a PRT system has been operating successfully on the Campus of West Virginia University in Morgantown, USA already since 1975!
