One or perhaps two buildings?? Sure, if you demand door-to-door
service. As I said, you have to be willing to do *some* walking.
Say, a mile at each end. That's fifteen to twenty minutes. A one
mile radius covers over *300* average city blocks. I think there
will be sufficient demand.

Yes, there are some people physically unable to walk a mile. Isn't
that what the short buses are for?

Indeed it would. Someone should tell DC's Metro. There seems to have
been two designers, who worked at cross purposes. In DC and the inner
suburbs the stations are so close together you can often *see* one
station from another, and travel is, as you said, painfully slow. In
the outlying suburbs, on the other hand, the stations are so far apart
that the designer apparently figured most people don't mind walking
six miles or so. (Six miles is the distance from the Vienna/Fairfax/
GMU station to the GMU campus which it supposedly serves.)

Both extremes are unreasonable. The ideal would be something like a
grid, where every point in the region is within a mile of a station,
and no station is less than a mile from any other station.

How did cars catch on? Who would buy a car before there were paved
roads and gas stations? And who would build paved roads and gas
stations before there were lots of cars in use? How did they get
around that paradox?

No, I mean one or perhaps two buildings. The number of "city blocks"
is wholly irrelevant in case such as this, as there are _no_ "city
blocks" present. I am talking about situations where a single office
park may occupy a large part of a square mile, with a handful of
buildings surrounded by vast areas of lawns and parking lots.

And if you want to make transit practical and convenient to users,
then one mile from the destination is at the very limit, if not
already beyond it. Sure, some people will walk a mile to their
destination, but many will not. Add in bad weather (heat, rain,
cold, snow, etc.) and the number of people willing to walk a mile
to and from work every day (after what may be a long transit ride)
plummets.

I'm not entirely certain that such is ideal, but that is rather
beside the point, as there is zero chance of any such thing
happening in the USA in the forseeable future.

I'm not quite sure what you are trying to say, here.

"Paved roads" existed long before automobiles.

And _any_ people bought cars before paved roads and gas stations
were common. This is a historical fact. Further, there are many
people now who drive their cars far away from paved roads and gas
stations.

As for gas stations, I don't know who opened the first ones, but
I suspect that they were opened by those selling or servicing
automobiles. And if one is not planning on driving cross-country,
one doesn't need a whole string of gas stations; one is enough.
I know many people even now who almost always buy gas at the same
station.

In short, your supposed "paradox" does not exist.

Since a single 8 car Sydney CityRail double deck train can swallow
2000 passengers at full crush load, I'd be quite surprised if there
aren't numerous urban rail transit operations that can easily top the
1000 passengers per train mark.

I don't know the exact figures, but I believe that the RER double deck
trains in Paris have a capacity similar to that of Sydney (if not even
higher). And an 8 car bi-level Metra (Chicago) train will easily
carry 1000 people.

I don't know about Sydney, but in the DC Metro, each train normally

Unless you count all the police, who are present mostly because of
fear of terrorism. But this is an unfair double standard. If there
was a Madrid style attack -- 190 dead -- once every WEEK on the DC

You just said there are nearly 200 traffic deaths per week in
Washington, DC.

According to Metro's website, 328.7 million trips were taken on Metro
in 2002. (Probably even more in 2003, but it doesn't say.) That's 6.3
million trips per week. If 190 of those 6.3 million trips ended in
death, that's one death every 33,000 trips. That's safer than cars.

This implies that there are 200 traffic deaths per week in Washington,
DC -- or rather in the area covered by the DC Metro system, which is
many times the size of Washington DC -- only if as many trips are
taken by car as by Metro. Metro's website also says 41 percent
commute via mass transit. Since many commute by bike or on foot,
that probably leaves cars with less than 41 percent of all commuters.

In fact, as far as I know there have only been six passenger deaths on
Metro in the 28 year history of the system. None in the past 22 years.
(Not counting death from natural causes.)

Not exactly. The "advantage" was supposed to be that you needed only one
trained driver per 1000 people with public transit whereas you need
one driver per person with the private single-occupant automobile. If
you can get away with one driver per 1000 people on transit but you
need 2 brakemen, 3 firemen, a best boy grip, 3 engineers, 6
conductors, and 200 ticket collectors, that advantage is not nearly as
great is it looks.

True. However, on each DC Metro train, there are no brakemen,
firemen, best boy grips, engineers, conductors, or ticket collectors.
There's just one driver, and no other employees. Except sometimes
policemen.

DC Metro doesn't carry 1000 people per train either.

Mind you not every train would have 1000 people on it. However,
with a full standing load a 6 car train will carry over 1100
people. Add another 325 and you will have over 1400 on an 8 car
train when WMATA get around to having enough cars to run 8 car
trains.

People in other sections of the USA view driving the same way, a
car equals freedom. The Japanese, at least those in major urban
centers, view car driving as a luxury that should only be done on
weekends, holidays, or when necessary, When I was in Japan, most
people I knew who had a car only drove it once a week to keep it in
shape.

The data is abundant that real rail, not your fairy tale rail is tens of
times more expensive to get a person out of a car than to support additional
capacity with roads.

What do you call books on tape that a lot of people use while commuting.
They also listen to talk radio, the news, and listen to music. They also
do a lot of things like eat, shave, put on make-up, read, make business
calls on the cell phone, even though it is certainly not recommended.

Anyone that actually commutes, and is not some dumb kid like you are
apparently, knows this.

It is a very small percentage of the land and significantly less than the
area taken per real passenger mile on rail, again not your fairy tale rail
which does not exist. In urban areas we are seeing rail take up about
three lanes to carry a fraction of a single lane on normal freeway traffic.

Oh where are they doing that? Its very rare these days because it is also
extremely expensive.

Using technology to allow cars to drive closer together under computer
control giving all the flexibility of roads such as taking different routes
than others while greatly increasing capacity at a very low cost. An
overhead picture of a freeway at rush hour shows that only 10% of the space
is taken by cars.

By increasing that to 30%, which is not difficult, then the capacity is
tripled. The cost is around 10,000 times cheaper to add the technology to
an existing road than it is to build a lane of light rail.

As technology advances, solutions can be envisioned that bump that figure up
to about a 15 to 20 to one improvement with much smaller vehicles designed
to take advantage of the technology.

The car companies have a large demand for this since people want to commute
without driving their car so they can do a lot more thing while having all
the advantages of a car and none of the commuter hostile characteristics of
trains that they in general hate so much as we see in polls.

You're assuming that the person is *in* a car. Not everyone can or
should drive, and not everyone who can drive owns a car, so roads
meant for cars are a poor and partial substitute for transit.

Which is part of why commuting in a car is enormously more dangerous
than commuting in a train or a large bus.

"Kid"? I've been commuting, to work or to school, for over forty
years. How about you?

Keep your eye on Arlington Virginia.

For years most Arlingtonians opposed extension of I-66 through their
county, while folks from DC's outer suburbs regarded Arlington as a
speedbump directly in their path. Finally, they compromised. I-66
was extended, vast numbers of homes and businesses were torn down, and
neighborhoods were split in two, but all with the understanding that
I-66 would never be widened.

It turns out that "never" isn't very long at all. There's increasing
pressure to tear down more homes and businesses to widen I-66. And
yes, it will be extremely expensive. I should know, I'm one of the
people who's going to have to pay for it, even though I don't drive,
and never use that highway.

You heard about the robot car race earlier this year? Even though
millions of dollars were spent, NOT ONE of the computer controlled
cars was able to complete the course. Not even at walking speed.
Even though, unlike in real life, they didn't have to deal with heavy
traffic. Or with any traffic at all.

They're barely able to make it work on Mars. With *no* traffic, with
hundreds of millions of dollars, and with the speed of a turtle.
And, oh yes, with a room full of people keeping an eye on things,
and rebooting when necessary. Which is pretty often.

It's a hard problem. I'd love to see robot drivers. But I don't
expect to see them before I retire.

> An overhead picture of a freeway at rush hour shows that only 10%

Sure, if traffic is light, and moving quickly. Around here during
rush hour it's closer to 90%, as traffic speeds vary from zero up to
at most about the speed of a bicycle. Robot drivers wouldn't speed
things up, but they could free commuters to spend their commuting time
doing other things. Someday. Or we could simply hire a bus driver
for every hundred passengers, or a train driver for every thousand
passengers, and combine speed, economy, safety, and convenience, with
no need for speculative new technologies. And with no need for every
commuter to make a major investment, and for every home and business
to set aside vast amounts of space to store those expensive single-user
vehicles, most of which are idle most of the time.

Bringing a car with you to a crowded city makes about as much sense as
bringing your oven with you when you go to a restaurant. Yes, ovens
are useful in restaurants, but there's a better way.

Sure. With Moore's law, in another century or so a robot driver will
cost one dollar (not counting the cost of the car, or the road, or the
parking space, or the fuel for the car, etc.), while a railroad will
still cost at least ten thousand. But what about in *this* century?

Yes, it *could* happen. And someone could invent Star Trek style
transporter beams, too. Wouldn't that make commuting easy! But
that's not useful *today*.

And there is no way we can afford the cost of get the land for separate new
transit corridors. Talking about an optimal design that can't be built is
a waste of time.

If you are inside the bus or train yes. If you include people outside bus
or train, then the car and transit rates are in the same ball park with
significant variations from system to system

It is also the reason car companies are spending lots of money on automobile
technology development. Safety sells and car companies will be providing
it. A very good approach.

I am often there. I doubt they are going to pay for all those large tall
building and pull them down to widen streets. Arlington is one of those
areas where they way over spent on transit and are now paying horrible price
for past bad decision.

Just like tube computers, rail systems are extremely ineffective is solving
transportation problems. You are not talking about this century, you are
wanting to live in the 19th century. Still thinking like a dumb kid.

The only reason why cars run around with just the driver is quite simple:
the law dictates you cannot pick up somene and transport them for a fee you
both agree upon unless you are a licensed taxi. This suits car manufactuers
and transit operators. It hurts the public and clean air...but what the
heck...it is politically correct. Car pools are set up to fail on purpose.

Sorry, even if it was legal, I still wouldn't pick up hitchhikers. I suspect
most people are like me in this respect.
