So Sweden and Masdar City are trying a different approach to the personal rapid transit situation. Their proposition has the look and feel of something the Jetsons would take to go shopping: PRT Pods.
PRT Pods. Personal Rapid Transit. Pods. The concept is similar to a taxi or a shuttle bus where the vehicles come to designated stops at frequent intervals. You have the option of booking a vehicle for personal use or for shared use, depending on your time needs and how much you are willing to pay.
Cost for PRT use is estimated to hover around the same as for a bus or subway when shared, and nearer more the cost of a taxi when used individually. The all-electric, zero emissions PRT pods run on established tracks. Best to think of them as a hybrid between a taxi service and a monorail line. Heathrow airport in London has a few in use, in addition to Abu Dhabi's Masdar City and Sweden pioneering the Pod Use for public transportation needs.
