Of course the range of PRT-type technologies was pretty limited 17
years ago but the basic integration concepts are still valid as are
the station location concepts. As part of the study, I spent some
time in France and Germany looking at their HSR stations and their
feeder/distributor systems and their land use development plans for
the station areas. For those interested, a summary of my report is
I tend to agree with the conclusions of the National Maglev
Initiative that there are very few locations in the US where HSR
makes cost-effective sense, the most promising one being Boston-to-Washington.

I wonder how frequent the service is for the Japanese bullet train or
the French TGV
or the German ICE system. I believe that the transfer penalty is an
that can be mitigated largely by proper interface design and scheduling.
I assume you are suggesting that bus size maglev vehicles on the main
(high capacity) routes
would be superior to high capacity trainsets - which might be true. Regardless,
you still have to provide some feeder/distribution service at the few
on the high capacity line. Some form of PRT might be useful for such
on the composition of the land use pattern in the vicinity of the stations.
Of course, a small vehicle system operating on a robust network might
be able to do the whole job as
well or better too. It could be a dualmode system using some type of

As I recall, they do have a concept for a suspended vehicle system
an in-vehicle switch. But, so far as I know, they are not currently working
I agree PersonalRapidTransit fits in with transportation modes long distance
enough not to be in personal vehicles, It can supply convenient "first and
last mile" service. That at least would apply to both HSR and airlines.
(And that presents a combination beneficial to a HSR terminal coincident
with an airport such as San Diego wants to do, and to which I have
Also doing this for mass transit such as LRT, commuter rail, etc, is
beneficial, and also useful to PRT development interest. But long term that
application prolongs the use, and causes overinvestment in a less desirable
mode. PRT could do the job itself. However if the mass transit commettment
is already made, there is overall gain.
We have discussed it before, and LA to/from San Diego areas is an example of
where both approches could work, but considering the thousands of
origin/destination pairs visited each day, mostly by auto, HSR augmented by
PRT seems the hard way to go. Especially because considerable of the
currently planned HSR route is distant from many locations of interest.
For LA/SD I'd prefer PRT rise to full height, demostarate it is an area not
linear issue, and propose a different form of high speed transportation.
Measured doorstep to doorstep.
At this point Brad will say: Robocars can do as well or better.

A lot of it has been built so far - it's a sunk cost - and needs to
be made more productive with a feeder/distributor in some locations.

Yes, the O/D pattern is likely to be very dispersed, but with a few
clusters widely spaced - but without having some decent O/D data and
forecasts, it would be hard to design a system that would serve the
clusters well, leaving the rest to conventional autos and robocars.
The HSR advocates are likely to get something built and perhaps PRT
could tag along given a few crumbs.

Yes, but who would finance the necessary studies to make the case and
stop the HSR advocates from getting all the money?
>At this point Brad will say: Robocars can do as well or better.
Certainly a possibility - given the millions of advocates they are
likely to have - especially in California.
