The technology used in the Milpitas PRT project was developed over decades by scores of people working to create a system that satisfies a list of performance criteria. While the design is detailed in the ITNS Business Plan, most people are satisfied learning about the high-level aspects of PRT capacity, cost and hardware.
Due to experiences with mass transit systems, some people question the ability of PRT's small vehicles to move significant numbers of people. They overlook our dominant transportation option, the automobile, that uses small vehicles to transport most of us most of the time. So, a better question is: Can PRT deliver satisfactory service using a few guideways spaced roughly 1/2 mile apart? Click here to see how a single guideway can transport as many people as multiple lanes of freeway.
Mass transit systems have also conditioned people to expect high price tags for building and operating public transit infrastructure. People familiar with the cost of building at-grade Light Rail Transit (LRT) and BART ($60M/mile and $230M/mile respectively) would naturally question the $30M/mile cost of elevated PRT guideways. Likewise, the goal of providing free service is also questioned. Click here to learn why PRT is relatively inexpensive to build and operate.
Engineers and gadgeteers are likely more interested in the hardware aspects of the PRT system proposed for Milpitas. Click here to get those details.
