As part of its plan to transform Heathrow Airport, BAA has started work on phase one of the world's first Personal Rapid Transit (PRT) System, to be deployed across the airport.

This innovative system is a completely new form of public transport and will revolutionise the way passengers are transported around the airport.

Developed by ATS Ltd and BAA, the Heathrow PRT system will consist of a fleet of 18 low energy, battery powered, driverless vehicles capable of carrying around four passengers and their luggage, which travel along a dedicated guide way.

The system brings significant benefits to passengers, providing a quick and comfortable service, with near to no waiting at stations, as well as contributing to improved environmental performance. BAA has worked with ATS to customise the PRT system to meet the unique needs of the worlds busiest international airport.

David Holdcroft, Project Manager, said; "This innovative system forms part of BAA's plan to transform Heathrow, improve the passenger experience and reduce the environmental impact of our operation through the development of cutting edge, green transport solutions.

"It offers a completely new form of public transport – one that will deliver a fast, efficient service to passengers and bring considerable environmental benefits, saving more than half of the fuel used by existing forms of public or private transport. Not only that, it's a world first."

"We are investing over £25m in the Heathrow PRT system and are committed to working together with ATS to explore the benefits of this world leading technology."

raham Bradburn , CEO of ATS Ltd added; "We are delighted to be implementing the world's first commercial PRT system at Heathrow. BAA has been an extremely loyal customer and shareholder of ATS and we are delighted to be working with them on this pioneering project. BAA has shown significant courage and foresight in choosing this technology, which demonstrates their commitment to the future of Heathrow and to all users who will benefit from this revolutionary system.

"Our ULTra system has many applications globally but for Heathrow it will provide improved reliability and efficiency of travel to and from Terminal 5, and will significantly enhance the overall passenger experience. Travel will be safe, non-stop and independent making for a more enjoyable journey.

The environmental benefits are also a major advantage of the system with carbon emissions 70% lower than car emissions and 50% lower than buses and trains. This benefit increases significantly when in congested areas such as Heathrow.

"This is a world first and a new approach to travel. This is transport for a sustainable future."

Phase one is currently under construction with 3.8km of guideway and 18 vehicles, linking Terminal 5 with the Business car park. The Heathrow PRT will be electrically powered, generate zero local emissions, and be typically 50% more energy efficient than the traditional buses. This will bring significant environmental improvements and help reduce congestion on airport roads.

Phase one of the Heathrow PRT system will open for passengers in 2009 following the opening of Terminal 5, on time and on budget. Upon successful application and operation, the system will be extended across the airport, and in other urban locations.
