Google co-founder Larry Page’s May 2 University of Michigan commencement speech: "When I was here at Michigan, I wanted to build a personal rapid transit system on campus to replace the buses. It was a futuristic way of solving our transportation problem. I still think a lot about transportation — you never lose a dream, it just incubates as a hobby. Many things that people labor hard to do now, like cooking, cleaning, and driving will require much less human time in the future. That is, if we 'have a healthy disregard for the impossible’ and actually build new solutions." http://www.google.com/intl/en/press/annc/20090502-page-commencement.html .
"I think it's exciting. I think it's clearly in our future." Mountain View Councilman Jac Siegal as seen on KTVU TV 10PM news and KTVU web.
ULTra is a battery-driven, 200-mpg-equivalent, elevated personal rapid transit (PRT) system with many four-person vehicles. First deployment is scheduled for London Heathrow Airport in 2010, to serve Heathrow's new Terminal 5. Working as circulator transit for office parks, airports, universities, and other major activity centers, ULTra is faster than a car. In these applications, ULTra makes carpooling, Caltrain, HSR, VTA light rail, VTA bus, and Google Bauer bus more effective, by solving the "last mile problem." PRT also enables longer bike commutes and shopping trips. Google's "transportation platform" (Google Transit, Google Ride Finder, Android GPS phones, etc) can help glue all the green transportation options together. A three-minute youtube video of ULTra can be found here: http://www.ultraprt.net/. Peer-reviewed market research for two other Bay Area transit-served major job centers, Palo Alto's Stanford Research Park (SRP) and Pleasanton's Hacienda Business Park, forecasts a PRT-induced commuting mode reduction from more than 80% single occupancy vehicle (SOV) down to 45% SOV. In these two studies, carpooling increased to more than 30% and transit increased beyond 15%. Such commuting shift could free more than 50 acres of surface parking for higher use. The PRT system should be part of VTA's transit system, with seamless fare box/fare gate integration.
"There is so much development going on right in this area. In 5 or 10 years we’ll have gridlock on (recently expanded) Highway 101/85 merge. We’ll need an alternative. The proposal to connect Google, NASA, and Caltrain makes sense as an alternative. PRT will be like a dam breaking. We’re all frustrated with current transit in the area." - Google employee.
PRT systems are being actively pursued for San Jose Airport, Santa Cruz, Alameda Point, and Virginia. One of the advantages of a PRT network "is that it offers a lot of flexibility. It's much less expensive than traditional transit. It doesn't serve the same needs as high-speed rail or BART. It's a complement to those systems," Laura Stuchinksy, Sustainability Officer, City of San Jose Department of Transportation. "We've concocted a system where local trips take an auto. That's our biggest tragedy. Streetcars, such as those used in Portland's Pearl District, and elevated people movers, like those in downtown Miami, are moving people from rail stations to their final destinations. But a new concept, PRT, may help revolutionize urban transportation, providing a cost-effective way to get people from train stations to where they need to go." - Peter Calthorpe, Berkeley-based Calthorpe Associates (Alameda Point, etc).

PRT is Rocket Science
ATS Founder (and ULTra PRT inventor) Martin Lowson is a rocket scientist and has worked extensively with NASA. Martin worked on the Apollo Space Program’s Saturn Rocket, where he led a team of over 50 staff. He was Chief Scientist of Westland Helicopters, generating the advanced rotor system (he holds the patent) now used on both Lynx and EH101 helicopters. This rotor set the absolute world speed record for helicopters. He has collaborated with multiple NASA wind tunnels on studies of aerofoil noise, helicopter rotor noise, and rocket noise radiation. He is Fellow of Royal Academy of Engineering, Fellow of the Royal Aeronautical Society, and Fellow of the American Institute of Aeronautics and Astronautics.
Self-Driving Electric Vehicles:
ULTra PRT is significantly more software, sensor, and communications intensive than traditional transit. An ULTra system may have 500 computer-driven vehicles driving with a precision better than +/- one inch laterally and longitudinally, with 100 position updates per vehicle per second.
The U.S. Department of Transportation (DOT) has developed a long-term vision of self-driving cars on U.S. roads called Automated Highway Systems (AHS). Automation will increase capacity (because cars will follow more closely) while improving gas mileage and safety. The current early DOT technology development project in this arena is called “Vehicle Infrastructure Integration” (link) and this effort is being complemented by automaker advances such as “stop and go adaptive cruise control.” All automobile manufacturers agree that it will be impractical to remove ultimate responsibility from the driver in a conventional road situation for many decades. In contrast, ULTra, offers fully self-driving vehicles now.
The ULTra system uses a battery-powered electric vehicle (EV) and will exploit advances in EV propulsion over the coming years. As of the current ULTra Version 1.0, the system design provides opportunities for recharge after every trip and required battery pack size is low, under 10% of vehicle empty weight.
