Car-Free City Enabled by Personal Rapid Transit (PRT)

Wednesday, July 28th, 2010

Imagine a city designed to be free of cars, trucks and buses, yet to include a transportation system that will whisk its residents to any destination quickly and quietly without stopping. Children, the elderly, disabled and poor would have mobility similar to that currently available to the rest of the population.  The buildings could be much closer together, allowing easier walking, and/or they could accommodate more open space. The lack of accidents (personal rapid transit (PRT) is two orders of magnitude safer than current forms of transportation) would bring significant social benefits and greatly reduce the need for emergency services. Crime would be deterred, since the PRT stations and vehicles would be under constant video surveillance.

Some would argue that such a city would still need roads for emergency response, maintenance, refuse removal and large delivery vehicles. However, there are probably other (potentially better) ways of providing these services. Buildings could be sprinkled for fire suppression and equipped to facilitate emergency evacuation. Emergency personnel could utilize the PRT system, which would provide faster access than any present road system, and bring their personal gear with them. Special PRT vehicles could be equipped to accommodate gurneys and function as ambulances, while others could be equipped to support fire fighting. PRT freight vehicles could remove trash and deliver goods. Low-impact vehicles could deliver large goods by slowly driving down the pedestrian walkways, linking the buildings to each other and the PRT system. Some of the infrastructure savings could be used to fund helicopter services for extreme emergencies or exceptionally difficult movement of large items. All of these concepts need to be refined and incorporated in the new city’s building and planning codes, but none seem insurmountable.

Such a city couldbe made more sustainable by incorporating numerous additional low energy/emissions/waste technologies and yet be built for less than the cost to build a conventional city, since it would require less transportation infrastructure. Fewer PRT vehicles (and vehicle storage spaces) would be needed than the cars they replace, because each vehicle would make 50 to 100 trips per day. Even though the city cost less to build, its value would likely be higher than a conventional city. Studies have shown that the value of housing served by a good transit system is increased 6% to 45%, and commercial land values have been shown to increase 24% to 103%.

Residents would be able to purchase homes at a reduced cost and to reduce their automobile ownership. They would leave any cars they did own in parking facilities at the perimeter of the new city. Recreational vehicles would also be stored at the perimeter. Those with jobs in the new city would seldom use automobiles and thus lead much safer lives with reduced waste of time. Opportunities to use technology for improving many aspects of life, beyond just transportation, could help keep the new city almost free of crime and allow the residents to have a truly wonderful standard of living. It is finally time to take our cities back from the automobile and let them serve human needs once more.

Modern Mobility, What is PRT and Why You Should Care

Wednesday, May 5th, 2010

Judging by the rapt attention (at times you could hear a pin drop) and the lively discussions during the breaks, the Modern Mobility Conference, held near Kansas City on April 23rd, 2010, was a resounding success. The conference was moderated by Stan Young, President of the Advanced Transit Association (ATRA) and marked the culmination of a project investigating the feasibility of a PRT system at the Village West development east of Kansas City.

Mokhtee Ahmad, Regional Administrator, FTA Region 7 welcomed the attendees. While expressing caution about the willingness of FTA to embrace PRT, he privately stated that PRT projects are eligible for FTA New Starts funding.

 ATRA board member and events coordinator, Larry Fabian, introduced the topic of automated people movers (APM). He stated that there are 146 worldwide of which 4 are PRT. APMs have historically been noted for their high costs. While PRT systems may require more sophisticated control systems, they will hopefully also reduce costs.

Peter Muller, president of PRT Consulting rounded out the first session with an introduction to PRT planning. He began by outlining how cars are ruining our cities by contributing to congestion, killing over 40,000 per year, contributing a third of all greenhouse gases, using more oil than all other uses combined and devouring property (at Village West four times as much land is devoted to roads and parking as to buildings). Conventional transit is no solution since transit’s mode share has barely changed in the last 20 years. He then outlined how PRT’s characteristics may allow it to address many of these problems.

Mr. Muller went on to educate the attendees in the technical aspects of PRT and how it should be planned for. He stressed that public participation can be key in dealing with potential nay-sayers early in a project. He outlined a public outreach process that has shown that people generally prefer small, private modes of transport such as cars, bicycles and PRT over rail-based modes and that the least-preferred modes are bus-based.

 The second session was focused on reporting on the results of the Village West PRT Project. Dr. Moni Al Aasar reported on BG Consultant’s analysis of structural and code compliance issues. He stated that the Kansas DOT had concerns about the ULTra guideway design as used at Cardiff and Heathrow. These concerns related to the fracture-critical, non-redundant nature of the design and the fact that it has out-of-plane loading. BG Consultants developed an alternative pre-cast concrete guideway design and Dr. El-Aasar presented estimated guideway costs based on this design. He also presented estimated costs for stations as shown in Table 1.

Table 1. Probable Construction Costs

$4.4M

2-bay Station

$48,000

$362,000

3-bay Station

$69,000

$465,000

 Dr. Steven Schrock, Assistant Professor at the University of Kansas, reported on the environmental aspects of the Village West PRT Project. No major environmental concerns are anticipated but NEPA requirements will have to be met if federal funding is involved. He discussed the methodology used to estimate the value of benefits deriving from reductions in automobile operating costs, onsite emissions and accident costs.

 Peter Muller reported on the work done to estimate ridership, system requirements, overall benefits and costs. In addition, he reported that Patti Banks Associates found that quite significant land redevelopment options become available through retrofitting the area with a PRT system. They also found that even more significant opportunities would have been available had the development incorporated PRT from the beginning.

 Mr. Muller stated that the benefits (including societal non-monetize-able benefits) outweighed the costs by some two-and-a-half times. Increased tax revenues plus a per-ride charge of about $0.50 would be sufficient to pay for capital costs in ten years. Ongoing operating costs would thereafter require a fare of approximately $1.00 per trip. He presented a comparison (shown in Table 2) comparing the viability of this project with another PRT project, a light rail project and a commuter rail project.

In summary, the PRT system seems viable and financially feasible. However, the study, which was undertaken as an academic exercise, had insufficient budget with which to adequately investigate important factors such as ridership, increased tax revenues and financing mechanisms.

Perhaps the most interesting part of the conference was the closing panel discussion moderated by retired Professor Alan Black. Tom Jacobs with the Mid-America Regional Council (MARC) said that transit is the number one solution they are working on. He was very impressed with the attributes and benefits of the PRT system and thought it was really compelling from an environmental standpoint. He considers the 60 to 200 square miles of parking lots within the MARC area to be environmentally damaging due to heat island effects, ozone emissions and increased storm water runoff. He saw promise in PRT’s ability to create vital spaces.

Douglas Bach, The Unified Government of Wyandotte County’s Deputy County Administrator, said that existing remote parking could be used if a PRT system was in place and that there are more and more reasons to park the car and travel around the facility. He felt that the system itself could be an attraction, but implementing it would be challenging. STAR bonds may be difficult to use because of restrictions. However, the recently enabled Community Improvement District has more flexibility on both the taxing and spending sides.

Dick Jarrold with the Kansas City Area Transportation Authority discussed how PRT could help solve the last mile problem experienced by larger systems. However, he expressed concerns regarding the need to verify costs, aesthetics, ridership, security, safety and impact on/of underground utilities. He said that, if the numbers are correct, Village West would be the type of facility at which to implement PRT. The big question is, “who bears the risk if it does not pan out?”

 Dick McReynolds, retired KDOT researcher encouraged the group not to get too hung up on specific costs or issues. This project was funded at about one tenth the usual costs and the results are quite encouraging.

Chris Ozimek, Director of Marketing for Schlitterbahn, explained that while a small portion opened last year, the 270 acre resort will take another four to five years to complete. It includes over four miles of waterways [which the PRT system would connect to]. The resort is designed to have people park and leave their cars for the duration of their stay. PRT could take this to a whole new level and increase the average length of stay.

Passenger Terminal Expo 2010 – Summary of PRT Presentations

Friday, March 26th, 2010

Heathrow’s PRT system: an update on progress. David Holdcroft, PRT Manager, BAA.

The Heathrow system has 21 vehicles. They currently have 12 to 13 running at a time. PRT has proven to be very space efficient requiring the relocation of a portion of perimeter fence only.

They have had some software and destination panel glitches. They are planning a full emergency exercise in mid May with the full system opening in late spring followed by a 1 year review process.

BAA is branding the system as the Heathrow Pod – a new travel experience – smart, personal and friendly. The new color scheme includes purple on the lower portion of the vehicles.

They have had a lot of interest in 3rd party sponsorship but passengers do not want internal advertising. They anticipate increasing the charge for parking once the system is operational.

They are considering adding automated way-finding where the rider enters their flight number, airline or car-hire company and the systems knows where to take them.

Snow and ice is dealt with by a special vehicle fitted with snow plows and deicing sprayers. This vehicle can continuously circulate around the system in inclement weather. The objective is to not have the system shut down before the roads do.

They have found that people want to share rides with others. This may become an issue that needs to be dealt with once more destinations become available. Having specific berths dedicated to particular routes may be a solution.

Once the system is open to the general public anyone will be able to use it from Terminal 5.

Insurance of the system has been no problem and is just part of the airport’s regular policies.

Personal rapid transit: how is safety assured? Christopher Elliott, Director, Pitchill Consulting, Ltd.

The Heathrow PRT system carried its first “real” passengers (members of the public participating in passenger trials) last week after receiving safety certification to do so. Final sign-off will be required before the system enters revenue service in June. The system is now real and transportation planners have to take it seriously.

The safety requirements for new transportation systems are much higher than those for existing systems. If introduced today, existing systems would never meet modern safety requirements. Modern systems have to be safe and be seen to be safe.

A good safety system leads to reliability. The Heathrow system safety goal is less than 10-3 fatalities per year (less than one fatality every thousand years).

Both leading PRT systems (ULTra & 2getthere) have built safety into their designs and are having it verified through independent certification.

PRT systems in an APM world. Thomas Ludwig, Head of Automated People Mover Services, Logplan.

PRT will be primarily a landside system with conventional automated people movers (APMs) being primarily airside. PRT competes more directly with cars and buses and is more suitable for landside. However, the cost/benefit of PRT could impact APM systems.

Translating lessons learned at Masdar into an airport environment.  Robbert Lohman, Marketing Director, 2getthere.

Benefits of PRT at airports include improved service, cost effectiveness, sustainable and green, makes new connections possible and provides improved accessibility.

All 2getthere vehicles have obstacle detection and will stop for a person on the guideway. Destination selection can be accomplished either outside or inside the vehicle. A blue medical assistance button will redirect the vehicle to the best station and alert responders that it is coming. The technology is now at an advanced stage and having the right people involved is more of a risk than the technology is.

The Masdar safety case is similar to the one for Rivium. Lloyds Register is currently verifying safety.

Masdar stations are not air conditioned and heat gain is a problem. Vehicles connect to a charging plate at berths to allow the air conditioning to keep running. Doors close after 4 to 5 seconds with no one entering or exiting. Dust and corrosion mitigation measures seem to be working.

The first phase at Masdar has 1.5 km of track, 2 passenger stations, 3 freight stations, 8 standard vehicles, 2 VIP vehicles and 3 freight vehicles. The ultimate system is planned for 45 km of track, 2,100 vehicles, 90 passenger stations and 100 freight stations. The current control system configuration can control 100 to 200 vehicles.

The perspective of cities. Suzanne Hoadley Membership Services Coordinator, Polis.

Daventry is still interested in PRT.

Cities considering PRT face the following challenges: legal, certification, risk aversion, visual intrusion, financial and societal.

PRT: the business case and revenue generation. Martin Lowson, Vice Chairman, Advanced Transport Systems, Ltd.

PRT typically reduces commute times by about ten minutes. The literature provides a number of studies indicating what the value of time is. Airport value of time is double that for other applications.

A study of all UK airport car parks found people pay £1.49 extra per stay for every minute they can park closer to the terminal. A good business case can be made for PRT for lots with more than 4,000 spaces that are close in and more than 6,000 spaces further out (10km). 18 hotel data points indicate room rates increase £3 – £6 per minute closer to the airport.

Various studies indicate home values increase 21% on average when they have good light rail access. Commercial properties increase 23% – 120% on average. Property value gain is $65M per km of track.

Master Plan Personal Rapid Transit Analysis for Baltimore/Washington International  Thurgood Marshall Airport. Peter Muller, President, PRT Consulting, Inc.

The purpose of the study was to investigate conceptual feasibility of PRT for: surface transport garages to terminals, secure inter-concourse travel, expansion to surface lots, LRT, Amtrak & the consolidated rent-a-car facility (CONRAC).

The following assumptions were made: speeds 15mph close in and 25 mph further out, minimum headways 2 and 3 seconds respectively, maximum theoretical capacities 3,600 and 2,400 passengers per hour per direction respectively. The system comprised 3.6 miles of dual-lane guideway, 7.7 miles of single-lane guideway, and 37 stations. 517 T-Pods were found to be necessary to provide an adequate level of service to the projected daily ridership of approximately 60,000 passengers.

The capital cost of $387M was compared to the capital cost of an APM ($1,194M) that had previously been studied to provide similar service. In addition to having a significantly lower capital cost, the podcar system had shorter trip times, provided seated travel for all and had the capability to deliver passengers inside the terminal building. It also had the potential to provide a loop serving the secure portion of the terminal/concourses. It was postulated that it could be satisfactorily demonstrated to the TSA that passengers entering the system at a non-secure station would not be able to exit at a secure station.

In addition to having lower capital and operating costs than the planned APM system, the PRT system was found to have operating costs of around 60% of those of the present bus service. It was speculated that it could potentially attract more cars to the long term surface lots and boost concession sales in the concourses.

The master plan, of which this study formed a small part, has not yet been adopted by the airport.

Vectus PRT operational experience applied at airports. Jörgen Gustafssen, Chief Technology Officer, Vectus Ltd.

Vectus safety complies with APM standards and is verified by a subsidiary of Lloyds Register. The system operates under distributed asynchronous control with a dynamic moving block vehicle protection system. They have no obstacle detection and have designed the guideway to be inaccessible.

Vectus uses a high-vehicle-flow station design with in-line bays. It is full duplex (board and de-board in the same location). They have found it important to have a spacious vehicle with good access. Their vehicle can be fitted with six seats. They have found actual boarding times to be less than anticipated. A 4-berth station can accommodate 8 – 12 vehicles per minute.

They are investigating a combined vehicle arrangement with 6 – 10 seats and room for 20-30 standing.

The Suncheon system will have 11km of track and 40 vehicles. It is mainly point-to-point but may have three stations. They hope the letter of intent will be finalized in a few weeks. Operations are scheduled to start in February 2013. It is a private-public-partnership.

Today’s airport innovations – tomorrow’s urban transportation systems. Malcolm Buchanan, Director Transport Planning, Colin Buchanan and Partners.

Airports and historic towns have a lot of similarities including congestion and remote parking issues.

Taxi earnings can be an important indicator of the potential for transit improvements.

Connecting terminals to the airport landside. David Little, Principal, Lea + Elliott Inc.

The accessibility, weight and small turning radius of PRT is an advantage. PRT development is such that it is now available within normal project implementation time frames.

Personal Rapid Transit (PRT) as a Tool for Enhancing Airport Parking Revenues

Wednesday, January 27th, 2010

Airport parking products typically are provided at a range of costs, depending on proximity to the terminal, and features such as valet service and shelter. Studies have shown air travelers are prepared to pay over $1 per day extra for every minute they can park closer to the terminal. In addition, travelers have been found prepared to pay more for parking served by personal rapid transit (PRT). Although not entirely clear, this willingness to pay extra is thought to be influenced by the high level of service provided by PRT, in addition to shorter trip times.

A PRT system provides a higher level of service more efficiently than a shuttle bus because:

  • There is less waiting (less than one minute)
  • Trip time is less because there is no stopping to pick up others or for other traffic
  • Trip time is the same every time
  • Platforms are at floor level – roll-on, roll-off
  • Everyone gets a seat
  • It costs less to operate
  • Curbside congestion and emissions are reduced.

Unlike conventional automated people movers, PRT stations are small and can be located at grade in the interior of parking lots. Numerous stations can be provided to minimize walking distances. Since stations are typically off-line, trips are non-stop and adding stations does not slow service down. Click here to see pictures of the PRT system at Heathrow Airport.

Small station sizes can be beneficial at the terminal end of the trip too. Numerous small stations can reduce walking distances to the airline of choice. In some terminals it may be possible to retrofit PRT stations in the interior of the building. Replacing shuttle buses with PRT service will reduce both emissions and curbside congestion.

PRT service to passenger parking lots could both increase the use of the lots and allow higher rates. The increased revenues, coupled with lower operating costs, could more than offset the initial capital costs of the system. In addition, a PRT system can be easily expanded to also provide inter-terminal transportation and serve other facilities, such as employee parking lots and rental car companies. Each rental car company would still get direct non-stop service, and the need for a consolidated facility could thus be reduced or eliminated.
