Tracking Cell Phones for Real-Time Traffic Data

stillgoogling writes to tell us the Associated Press is reporting that the Missouri Department of Transportation is stepping up a project to track the mass movements of cellular phones. This project is designed to use the movements of cell phones to map real-time traffic conditions statewide on more than 5,500 miles of road. From the article: "Officials say there's no Big Brother agenda in the Missouri project -- the data will remain anonymous, leaving no possibility to track specific people from their driveway to their destination."

    Our company has been experimenting with this idea since a year or two, to measure the traffic on smaller "B" roads, that unlike highways do not have traffic measuring equiment built into the asphalt. Here is a short article (In Dutch, use Babelfish), and the site with the traffic information (Type in the 6 digit number shown into the "log in" box). They obtain phone location data from one or more GSM providers. The data has been filtered so they only get generic location data; no phone numbers or other identifiers are provided.

  3. Quantum theory of traffic management by n0dalus · · Score: 4, Interesting

    I have a theory which states that traffic, when essentially quantized (grouped into bunches of vehicles moving between traffic lights), exhibits several quantum mechanisms.
    For example, whether or not a quantum of traffic (bunch of cars) reaches their intended destinations, the affects on the traffic of that area are the same as if they really did reach their intended destinations. This is essentially because people generally choose routes which they think will be the fastest or easiset, and people think "Oh it's Friday afternoon on the start of a long weekend, lots of people will be going out of the city for holidays down highway X, I'll go a different way." Hence whether or not a quantum of traffic is going somewhere, people avoid them just the same.
    This can be simulated by a computer in a combination with this kind of system, to very accurately time traffic light sequences so as to reduce the average waiting time per vehicle across a large area. In theory it is possible to quantize traffic (eg, stop/allow single cars until they end up in a bigger group) and time traffic lights so that almost no waiting at traffic lights is needed. As long as you travel within one of the quanta you would have green lights all the way.

  4. Solution: Power Off Cell Phone for Privacy... by Ron+Bennett · · Score: 4, Insightful

    Simple solution is to power off the cell phone; some newer models are rumored to never truly power off - simple work-around if unsure / paranoid is to then place the phone into a shielded bag similar to what is provided to folks who use EZPass.

    Cell phone tracking is already so prevalent that use for traffic monitoring is merely another extension of the extensive data collection that's already being going on for quite some time from cell phone users, including actual data, such as text messages sent/received.

    On an aside, most folks have no real need to always have their cell phone on when driving - let the voice mail take calls and help keep the roads safer; due to lawsuits some companies forbid use of cell phones while driving, so why even leave the phone on...

  5. Fixing traffic results in other benefits. by oneiros27 · · Score: 4, Interesting

    But you forget -- in some regions, traffic is a major issue. (eg, the Washington, DC metro area) -- if legislators can get get traffic issues cleaned up in an area that has major problems, it could mean an easy re-election for them.

    If they're actually thinking about the general population, and not themselves, they'd be looking at the other benefits that something like this could provide --

    • Cheaper ways to estimate traffic growth, and determine where to allocate money for capacity improvements.
    • Faster detection of accidents, for improved emergency response.
    • The ability for the population to better plan their routes to work, resulting in a happer, more productive workforce.
    • The ability for trucking companies to better plan their routes, possibly making it more likely for them to route through the state (resulting in sales from diesel, food, lodging, etc)

    Yes, there are potentially less-than-ethical reasons for wanting a system like this, but there are pleny of reasons why something like this is a benefit for the general population -- now, is the money for this project worthwhile? For all we know, it's being done because one of the politicians is getting kickbacks, and they're spending too much, as compared to other, more worthwhile projects for their state (in terms of Benefit/Cost Ratio or some other measure used to determine project viability)

    It is the job of the secret service to investigate these threats against the president, and it has been doing this for a long time without any history of abuse of power.

    Acting on a tip from a Wal*Mart photo clerk, the Secret Service visited a high school and confiscated a posted depicting a student giving a "thumbs down" gesture to a photo of Bush. The last time I checked the confiscation of personal property required due process and expressing dissatisfaction of either government in general or even specific officials was explicitly allowed. I'd say this counts as a fairly obvious abuse of authority.

    Other sterling examples of abuse of power on the part of the secret service include:

    The arrest of husband and wife Nicole and Jeff Rank for wearing T-Shirts that read "love America, hate Bush" (who were otherwise not disruptive)

    The official policy of the Secret Service (since rescinded) of segregating and concealing protesters at public appearances

    Janet Voorhies and two companions were denied entry to a Bush event on the grounds that they were wearing T-Shirts that read "Protect Our Civil Liberties"

    Perry Patterson was arrested for simply saying "no" when Cheney declared that Bush has made our world safer

    No history of any abuse of power? According to official accounts the secret service has a 0% rate of abuses of power within their ranks. This is simply impossible: no agency can make the correct hiring calls 100% of the time and any claims to the contrary displays an abuse of power by covering up mistakes - at the expense of those who were violated.

    Having a perfect track record is impossible: having a very public record of swiftly correcting any problems isn't.

    Anyone know what ever happened to the ECHELON project, which is a system intended to monitor literally every piece of human communication on the planet and mine it for analysis later?

    Paranoid nutcases with little knowledge of basic electronic intelligence strategy have flooded the internet with hysterical rants and lunatic ravings about ECHELON. It's almost always traceable to a specific error in reading comprehension, i.e. the failure to distinguish between "capable of monitoring any communication" and "capable of monitoring all communication". The former is true. The latter is not. There does not exist enough electronic analytical capacity to monitor all communications. Anyone who has worked in electronic intelligence knows that one of the primary focuses is tasking: knowing when and where to apply limited collection resources. 99.99% of the electronic communication in the world is inconsequential chatter, and is very easily identifiable as such. NEWS FLASH! The NSA knows your 90 year old grandmother's phone calls aren't worth listening to, so they don't! I speak from experience as a former Signal Intelligence Analyst with the US Army-- they spend most of their time trying to RDUCED the amount of stuff they have to analyze. Really, the theory of "ECHELON listens to everything, all the time" fails the common sense test on so many levels, it boggles the mind why anyone would take it seriously. So the computer flags (say) every utterance of the word "bomb" and "embassy" or some such, eh? Well THEN what? Who goes through the enormous daily log of such flagged conversations? The obvious answer is that they cut down the log by not bothering to monitor communications between irrelevant parties. The tin foil hat crowd thinks the government is listening to them, when the truth is the government doesn't give a shit about them because they don't matter.
