        I think you got that backward: a cell phone detector can only count cell phones. For example, a bus with 18 people using cellphones on it is not 18 cars. A video camera, on the other hand, can tell you exactly how many cars are on the road, and what types and sizes, and their speeds.

        • As an aggregate, X cell phones will mean Y cars. It would take very little money to do such a study and figure out what the rate is.

          You'd probably need to reevaluate it each year or after any laws go into effect that could effect the rate (such as laws saying you can't talk on a cell phone while driving - either in Missouri or in a neighboring state.)

          It isn't the number of cell phones, it is how fast they move from cell to cell -- thus telling you the speed that traffic is moving on that section of highway. Estimating the number of cars and trucks in the traffic jam is an exercise left up to the reader.

          A cell phone tracker can tell how fast traffic is moving by knowing how fast each particular phone traveled from point A to point B. You don't really need to know how many cars/busses/trucks are on the road. You only need one cell phone traveling to tell the speed of the traffic which is the important information here.

Similarly, I am also fairly certain that the percentage of riders with turned on cellphones is also more or less constant. So...

      From Lectric Law Library [lectlaw.com]:

      CIRCUMSTANTIAL EVIDENCE - Circumstantial evidence is best explained by saying what it is not - it is not direct evidence from a witness who saw or heard something. Circumstantial evidence is a fact that can be used to infer another fact..

      Circumstantial evidence is generally admissible in court unless the connection between the fact and the inference is too weak to be of help in deciding the case.

      You need a lot more than a single circumstantial fact to "prove" that someone committed a crime. Rather, you need a large number of such facts that close in on the case and provide a single, inescapable conclusion. Even if you have done that, be prepared for the defense to argue each point under a "hypothetical" context, thus convincing the jury that the "evidence" is nothing more than a set of coincidences presented in such a way as to make the defendent look guilty.

      Not hypocritical at all.

      A cell phone is trackable even when its owner is not talking on it.

      This article [howstuffworks.com] provides a good outline on what happens. Basically, there's a control channel, through which your phone communicates whenever it's got a battery in it. Your phone listens for an SID (System Identification Code) on this channel, and tells the appropriate MTSO (Mobile Telephone Switching Office) "Hi, I'm here". The MTSO has to know where you are, so that it can route incoming calls to the device.

      All that's happening here is that the traffic monitoring folks are listening in on the back-channel communications between a large number of cell phones and base stations, and using the changes in location (as averaged over a large number of devices) to guesstimate the average speed of traffic. Individualized cell phone tracking is useless for a traffic flow application, so it's actually highly likely that the traffic folks are telling you the truth when they say that individual data isn't being logged, and that only aggregate data is being recorded.

      The technology's nothing new - a system like this is necessarily a part of any wireless phone system, otherwise your phone couldn't ring when someone called you. No such agency is now permitted to do such a thing domestically (a sentence that can be parsed in at least eight ways, all of which are true), but they probably don't, because everyone else who's also interested in individualized tracking, is already doing this, has been doing this for years, and is using other tricks in software to locate their targets to within a few meters, all in real-time. They aren't using the traffic-control folks' data, because they don't need it.

Surely, there ought to be technological solutions to allow tracking while reliably protecting individual privacy. Perhaps, each cell phone could generate a short term session identifier (24 hours in duration and not tied in an obvious way to the phone number) for use in such tracking applications? It might also be feasible to allow paranoid phone owners to opt out.

HWY40 doesn't have exit and on ramps that are the proper length, so they want to do construction to fix all that. If they shut that highway down it will double or triple many peoples morning commute.

    Of course, if people would simply stop trying to cut everyone else off, and not drive like total pricks, there wouldn't be any problem.

    1. The information will be organised and recorded at one central location - which will break
    2. It uses the latest technology and, i assume, some stastical/mathematical techniques - which will probably be
    incorrect and will end up giving false results anyway
    3. 1 and 2 will cause extra congestion and extra cost - yippee!!!

  • I've always thought that it was interesting that people expect privacy when they're litterally broadcasting something in every direction - I don't expect privacy when I'm yelling out something on a crowded city street. Why does changing the medium from audible sound to EM waves give you an expectation of privacy?

    Not that I don't want privacy when I'm talking on a cell phone - in fact, I'd pay more for say, some reasonable level of encryption on my cell phone.... I just don't think its some sovereign right

    • I'm in firm agreement. Broadcasting is broadcasting.

      If I want a true expectation of privacy, then I need to secure my network. That means physical security. If you tap into my line and read my data, then I'll be relatively upset, and I think you've done something wrong. If you overhear what I'm saying, then that's my stupid fault.

      Granted, there are limits to this. I think it's wrong to go around with laser microphones and try to listen in on people's conversations when there is an expectation of privacy.

    • You might think I'm wrong about this but consider satellite TV signals - DMCA concerns (which most of us don't agree with anyways) aside, I've always just thought.... you want me to pay for satellite service, fine. But to say that I can't interpret the signals YOU are beaming in to MY house in any way I want (by using a decoder, etc.) is ludicrous - if you don't want me to do something with them, DON'T BEAM THEM INTO MY HOUSE. Or try and use proprietary technology, encryption algorithms, etc. to prevent me

    Speaking as a resident, let me give you an example of what passes for "sophisticated". For several years, after people complained about tax forms being sent out with their SSN's on them, they started encrypting them. How? Using a substitution cipher (e.g., 4 for 1, 7 for 2, etc.) Now that's sophisticated...
