The Sunnyhills Neighborhood Association (SNA) is working toward a PRT feeder
from their neighborhood in northern Milpitas to the BART/LRT/bus transit center in the south.

What is PRT?

Click image for more photos.

Cabs are small, light-weight, electric powered, and computer controlled. Each cab accommodates 1 to 4 people and travels 25-75 mph. (Click to see more photos.)

Guideways, with diameters of as little as 3 feet, can be routed through small spaces and even into buildings. This full scale model was displayed in Milpitas Town Center (August 2003).

Guideway capacity: one guideway can handle an estimated limit of 6,000 people per hour (pph), equivalent to three freeway lanes. (Click for details.)

Stations are 1) small, 2) spaced about 1/2 mile apart, and 3) off the main line so cabs can proceed non-stop to their destinations. (Click for animation and drawings.)


  • Affordable to build/construct (1/3 the cost of LRT).
  • Affordable to operate and maintain (1/3 the cost of buses).
  • Affordable to the consumer/user/rider (from free up to $2 per ride; political choice).
  • Affordable to modify/expand/re-use as needed (due to loop design, small vehicles and modular parts).

How does PRT work? - Select destination station and pay. Board the cab. Enjoy the non-stop, elevated ride. Exit the cab.

Proven Technology - Most hardware components of PRT systems are "off-the-shelf" technology proven in over 150 Automated People Movers (APM) around the world. Software control systems, although proven in software simulations and in Internet routing, requires exhaustive physical testing before public use (completed for ULTra and 2GetThere).

Environmental Impact - PRT uses less energy, land, and material resources than cars, buses and trains. It's also quieter, cleaner, and more neighborhood-friendly.

Non-stop, origin to destination transport offers three big advantages over corridor transit which stops at stations along the way:

  • It effectively doubles the average speed of transit so people arrive at their destinations sooner.
  • Starts and stops consume energy; non-stop transit saves energy, money and pollution.
  • Since the cab will automatically go to the destination station, passengers get uninterrupted time to read, work, meditate, text, cellphone, or even sleep.

How could we use PRT in Milpitas?

  1. Offer "ferry" service for cyclists and pedestrians 1) over the railroad tracks to connect Yosemite Drive with Curtis Avenue, or 2) over Montague Expressway near the BART station.
  2. Create a one-loop circulator to connect nearby areas (high-density housing, Great Mall, The Pines neighborhood, new elementary school and public park) with the BART/LRT/bus station.
  3. Link Main Street and the Midtown Area with the BART/LRT/bus station and City Hall.
  4. Provide city-wide, networked service which connects most residential areas with most popular destinations.

The blue lines in the image above indicate guideways and the ovals indicate station locations.

Questions and Answers

What do you need to know before supporting PRT in Milpitas?

Help SNA bring advanced transit to Milpitas.

As the next step toward a PRT "ferry" over the railroad tracks, SNA is seeking to fund the City's portion of the necessary $50,000 Environmental Impact Report (EIR). We only need $10,000 (20%) due to progressive transportation funding rules. After gathering $10,000, SNA will work with the City to secure the remaining funding and generate an EIR. Engineering and construction could follow the EIR.

SNA will act as escrow agent until the full $10,000 is secured. Questions can be answered by SNA Secretary, Rob Means (408-262-8975, Make checks (minimum $20) payable to:
