London Heathrow - Central Terminal Area Study
This year the world’s first Personal Rapid Transit (PRT) system will open at London’s Heathrow Airport (LHR), connecting one station in Terminal 5 to two remote stations in the business car park
Long-range planning at Heathrow involves the option to expand this system to the Central Terminal Area, with a network connecting three northside passenger and staff car parks to the CTA (Terminals 1, 2 and 3).
With the primary objective being to solve critical problems of congestion in tunnel access to the CTA, a study of such a network resulted in the following conclusion:
- Excellent value for money, especially compared to APM: 30-year NPV of +£73M at 6% discount.
- Saving in operating cost of 40% over current bus service.
- Typical passenger time saving of 60%.
- Premium service for passengers
- Valuable reduction in emissions
- Highly efficient use of space
Details of the study are given below - see also the London Heathrow CTA Study Assessment page and the Assessments Overview page.
Heathrow Long-Range Objectives
- Solve critical problems of congestion in tunnel access to Central Terminal Area (CTA) - both for staff and air passengers.
- Offer a transport solution which minimizes impact to LHR during construction and operation.
- Provide a service with high availability which is very resistant to disruption.
Tunnel Links
Existing sidebore tunnels are well matched to ULTra:
- Up to four tracks per sidebore
- Full use of sidebore offers considerable excess capacity over north side connectivity requirements
- Outline Safety case approved by HMRI
Travel Time Comparison
Connections
Results of initial studies into car park and terminal connections found:
- Excellent service to car parks can be provided
- Service to stops at Terminals 1, 2, 3 with stations inside buildings where appropriate
- Unexpectedly simple integration with complex CTA site
- Small scale infrastructure permits service at high or low level floors
- Low interference during construction
- Simulation results confirm practicability
Cost-Benefit Analysis
The results are based on detailed costing, reported car-park demand, travel time measurements and simulation of the network.
- User benefits (time saved): £5 million p.a.
- Operating costs: £0.7 million p.a. less than shuttle buses
- Capital cost (incl. vehicles): £3M per kilometre
- First year rate of return: 25%
- 30-year Net Present Values at 6% discount: £88M user benefits; £12.5M operator benefits
- Overall NPV after investment: £73M (some of user benefit could be converted to higher charges if required)
- Reduced emissions by 2.9 tonnes CO, 0.9t VOC, 12.9t NOx, 1.7t PM10, 311t CO2
- Noise levels much lower than background
