There has always been a solution
to [traffic congestion], but both politicians
and the public simply refuse
to accept that tolls are the answer.
Politicians are afraid to impose another
cost on voters, while most drivers assume that roads
should be costless. Yet there is no other viable solution. Forget
about new road construction - which is too costly - and
car-pooling - which is too marginal - the only real answers
are incentives that change driving behaviour.

On September 17th, Stockholm residents voted to approve a traffic
control system that will see car drivers pay tolls to
enter the city. Unlike the City of London that charges a flat
fee of around £6 to enter the city, or Rome which simple bans
cars from certain parts of the city, Stockholm has conducted
one of the most sophisticated traffic-management systems as
part of a plan to reduce traffic congestion, pollution and improve
quality of life.

The system, first theorized by
Nobel-prize winning economist
William Vickery in the 1950s, is
known as congestion pricing in
which drivers are charged different
amounts depending on the time of
day. In other words, the project was
a giant behaviour-control experiment
to see if driving habits can
be changed thereby distributing
traffic more efficiently throughout
the day. And in the process encourage people to use public
transit. What opponents of tolling need to understand is that
even small declines in the volume of cars on the road can
have a huge impact on the flow of traffic. Take 10 percent of
the cars off the road during rush hour, and rush hour gridlock
almost vanishes.

But what cities are afraid of is that this 10% reduction will be
achieved by a 10% reduction of employment or retail business in the
city.

Tolls work if all of the employees/shoppers in a city already live
within the city. Then, you are discouraging a few commuters or visiting
shoppers. But if your city depends on these people to support its
businesses AND there are viable options in the surrounding suburbs,
tolls kill the city center.

There are several options to make traffic in the heart
of the city lighter.
I grew up on the edge of Boston and, as an adult, usually took my car
downtown only if I would go there and back between the two rush-hours.
Otherwise, I took the "rattler" (trolley) or Banana (yellow and comes
in bunches).
In Coventry, I lived only 1/2 mile out of the precint, so often
walked. I still do in the residentials areas in and  around San Diego.
Still under seventy, so probably will for years.)

Hey,Stude,I was stationed at Hanscom Field 1971-1974.(Bedford)
I've taken the T a few times,drove downtown when the parents came to visit
and wanted to see the tourist/historic stuff.(they weren''t big walkers,or
I'd have taken us all on the T.)

Congestion is already killing the city center.  What difference does
it make if people avoid driving downtown because the roads are clogged
with traffic or if people avoid driving downtown because the roads
cost money to drive on?

In either case, what will happen is that some people will decide to
travel at non-peak times when the cost (in either money or time) is
lower. Which, of course, was the desired goal.

Using the same analogy, you don't hear people say  "Nobody eats at
Wolfgang Puck/Nobu/Chez Paul anymore because it's too expensive."

If it were that easy then why not just add 10% more capacity and
problem solved.  The fact is, any reduction will shortly be taken up
by more people IF it's truly free market, but it never is, it's a tax
on some people (the ones in cars) to pay for a better environment for
others, the people who own the property by the roads.

Not quite. Whenever you increase capacity you have induced traffic to
deal with, which quickly erases any gains. The way things are
structured now there is no economic disincentive to consume as much
road capacity as you can - which is why we have no excess road
capacity. The cost of driving has to be commensurate with the impact
of that driving on everyone else in order for the system to be able to
balance itself. If congestion pricing isn't the best way to do that,
then please tell me what is.

No problem, then -- close roads, thus reducing capacity and congestion
via the reverse induced traffic effect.

Nonsense.  There's only so much road capacity a person can consume,
and doing so costs him money and time.

We have no excess road capacity largely because the NIMBYs and BANANAs
not only prevent and delay road construction, but get "traffic
calming" instituted to destroy road capacity.

You miss the point.  If ALL you do is something that reduces traffic
10% then by definition you have done exactly the same thing as add
another 10% capacity.  The LAST time you added 10% capacity what
happened?  Just as you stated, induced traffic filled it right back
up.  That's going to happen for this "congestion pricing" thing too.
Just as new capacity is nice when it's new and not being used, this
"new" capacity will disappear over a short period of further growth.
If people were willing to put up with the road at "capacity" then it
follows that new people will come along and refill it to capacity no
matter what you do to create more capacity or remove SOME drivers.  If
I'm wrong, tell me where any place that has instituted congestion
pricing has seen it "solve" anything for other then a short period of
time till more people come along.  NONE of these strategies will work
as long as you continue to allow further growth of a region.  Unless
you consider ever higher taxes to support more and more highly
subsidized mass transit a solution - that's just a way to trick people
into paying taxes indirectly that they would not willing pay directly.

LOL!!!

So let's recap your theory:

Congestion pricing is introduced on a road. 10% of drivers think the
price is too steep, so they stop driving on that road. However,
because congestion is now reduced on that road, those same drivers who
yesterday thought the price was too high suddenly decide the price is
just fine and start driving on the road again, bringing congestion
right back up to where it was.

Does anybody see any flaws in Ashton's theory?

You don't understand what I'm saying.  It won't be the *same* drivers.
It will be NEW people who move in.  There will be, among those NEW
people, some of them willing to put up with the congestion just like
there was before the extra cost was tacked on.  So within a few years
a whole new group of drivers will be out there clogging the road.
Sure, they will pay a toll, so what, they will still be there clogging
up the road OR if they are not there, they will be clogging up
alternate routes, either way, you wind up with the same overall
congested mess.  The only difference is that the average user is now
paying higher taxes and you can be sure that after a few years the
politicians will be using that tax money for things other then the
highways/users they collect it from

.  Or if it's privatized it will just become huge profits for some
private company.  Private companies have no incentive to provide extra
capacity if it's not economic to do so.  Once they own the main
arteries in an area where it's very expensive to build more, they
won't build more, they will just rape the users of the existing routes
since that's where the profit is.  That's why these "free market"
schemes are a false hope.  The only group they are good for are the
owners of the road.  If any of these schemes made sense for the users
the gvt could simply do them themselves and then the public would be
the beneficiaries of the "profits".  Follow the money.

So why would these NEW people be any more likely to pay high prices to
drive on the road than the original 10% who bailed because it was too
expensive?

But OK, let's assume you are correct, and there are a group of people
who hate congestion but are willing to pay a fee to drive on this
particular road. All you have to do is raise the price some more until
your desired goal of a 10% reduction is met. There is GUARANTEED to be
a price point where that will occur, and, once reached, that
equilibrium can be maintained indefinitely. The same cannot be said
for building more roads, as it's not only too expensive but it's
physically impossible to widen roads fast enough to keep up with
unbridled demand. That's why bridling the demand is the only viable
solution.

FWIW, They built a toll-road around a major creep-and-beep motorway in
the Birmingham (GB) area. I expect that people in a hurry and freight
carriers all use it. I did myself when travelling with the Studebaker
Owners Club (UK) - and that was on a Sunday. Smooooooth!

That would be a fine solution IF the private companies actually PAID
for the road AND were not given a monopoly.  Every time someone looks
at these "free market" schemes they find that the only "free" part of
it is how the state give the lane and existing road FREE to some
private company.  As to the more limited concept of tolls to force
some users to travel "off peak", that is just social engineering.  If
you find that acceptable then you should be agreeable to the notion
that we should charge a HUGE tax on ANY car purchase since it will
discourage car ownership and force people to ride the bus.  It's no
different in outcome, just a different way to screw people who can't
afford to pay the arbitrary "toll".  And, of course, you would support
a high tax rate on suburban homes and a low tax rate on central city
slums to encourage people to "live where they work".

No, they're different drivers -- the same drivers who would magically
be induced to appear on the road if you increased capacity by 10%.

Assuming you believe in induced traffic at all, the theory holds.

So this is your capacity for logical thought? You think that induced
traffic works the same with a toll road as it does with a "free" one?

Sure.  The induced traffic theory says that road capacity is so
desirable, that no matter how much you build of it, it will fill up.
A piddling little toll is not even going to make a dent in such
insatiable desire.

That depends on who sets the toll.  A sensible private owner, if allowed,
will determine by experiment exactly what level of tolls bring in the most
money.  This level will vary with time and day (as on the 91 Express Lanes)
and will be at the point where the number of drivers willing to pay it is
just below the number that would produce stop-and-go traffic.
