While I am probably not as optimistic as Mr. James about the uses of PRT, I certainly want to see investment and exploration of the possibilities. I think the airport and college campus applications are most likely to be early successes. With further development, feeder systems to other transit modes may replace buses in some areas. So far, ULTRA crew seems to be doing some things right and have production vehicles and testing ongoing with an operational system beginning next year. Ultra's low speed is at least competitive with buses and light rail which average under 25 mph.

What remains to be seen is whether the touted benefits actually accrue: lower operational and capital costs, decreased energy usage and pollution, increased service and decreased wait and travel times.
