This is precisely my point. It's only good in some areas.

But traffic control centers are becoming very common. If you look at GPS
receivers for example at Garmin you see that probably half them now receive
traffic control data to calculate the fastest route to a destination. That
indicates that real time traffic information is available in a high
percentage of metropolitan areas.

I did not find how many Metropolitan Transportation Management Center there
are in the US, but if you Google "Metropolitan Transportation Management
Center" you will see there are a lot of these centers in the US.

Again, you're proving my point. All TMCs are not created equal and
they are still being improved and still cover mostly urban areas.
From a DOT's point-of-view, they have to take care of the entire
state, not just the metro areas.

I wonder what data Garmin is using to determine alternate routes in
areas like New York City, where arterial coverage is just getting off
the ground. My bet is that it's not much better than snagging a
number out of the sky.

The technology will improve; deployments will increase (especially if
the ITS funding issue is ever resolved); but as of right now, it's too
quixotic to be claiming that we have enough information to say that
ITS is a panacea for congestion.

here.. take a gander at this:

http://www.gpsbusinessnews.com/index.php?action=rubrique&numrub=3

and this:

http://www.msnbc.msn.com/id/9698139/

the private sector ALREADY has the communications infrastructure and
is building more.

they also are already doing real-time traffic status anywhere that
there is traffic with connected cell phones... rural or urban

what the Feds are doing .. is looking at different kinds of
information .. that might flow from/to a car to ....another car and/or
"infrastructure" that communicates...

but my point is .. that the communications backbone.. is already
there...

and now we're talking about what kinds of information would move on
that backbone... and so..yes .. the Feds might have info that is
specific to their function (like alerting a driver to exiting too fast
on a ramp exit).. but the method for communicating that info.. already
exists in most places via private entity cell towers, FM broadcasts
and Wi-Fi as well as "in-car" privately owned infrastructure such as
cell phones and GPS units.

The Feds can leverage this existing infrastructure.. rather than build
separate new.. and duplicative infrastructure.

They can actually better leverage their funding to focus on the data
function rather than how it moves...

You're missing the fact that, when properly evaluated, cell phone
probe technology has yet to pan out. See the Transportation Research
Record, Volume 1993 (2007), pages 51-58 for starters.

ALK Technologies yesterday announced that customers of its CoPilot
Live mobile phone navigation system will be able to benefit from an
integral connection to Microsoft's Live Search API.

By entering a search query e.g. 'bank', 'coffee' etc you will receive
a list of the matches closest to your current location. Connected
search is the next big evolution in navigation and provides access to
a huge variety of dynamic real-time information.

CoPilot Live sends its queries to Microsoft's Live Search API via the
mobile Internet (a data connection is required) and provides its
navigation users with instant access to a huge range of location-
specific information. Search results provide details of nearby
businesses, shops, restaurants, and leisure facilities, which can be
previewed and added to an itinerary for spoken and on-screen turn
guidance. The system will also be capable of displaying community-
generated reviews and rankings, helping users make an informed
selection.

The feature will be available on new products from April and an update
will be made available free of charge for existing customers.

Hey guy.. you're going to go to a Transportation Publication to find
out what is going on in the marketplace?

Who would YOU trust to deploy a cost-effective user-pays network
infrastructure?

Tax Dollars will not solve the "cell phone probe" problem.. but the
marketplace will.. much faster and without taxpayer funding...
