The new driverless Transport Pods recently launched at Heathrow, will eliminate 50,000 bus journeys between Terminal 5 and the car park. Passengers board the pods which are lined up and waiting for them and press a touch screen which closes the doors and sets the pod in motion at speeds of up to 25mph. There are 21 Personal Rapid Transport (PRT) pods which circulate around a 3.8km congestion-free track which are said to use 70% less energy than a car and 50% less than a bus.
The journey is on demand and non-stop from start to destination and the pods even recharge themselves at battery points when not in use so they are always ready to go.
