Hardware-Based Commute-Map Gadget 261

coreymetrics writes "Anyone have one of these things? While it's no substitute for an improved mass-transit solution in the Puget Sound area, TrafficGauge's new gadget sure looks like it beats any PDA or cell phone auto traffic map I've used. It uses the same data that powers the Washington State DOT's indispensable website. Now why can't auto makers put this kind of thing in a dash instead of mostly worthless GPS navigation and DVD units?"

      Several Mercedes-Benz GPS navigation systems actually do support the reception of traffic information embedded inside of radio signals.

      Supposedly the Audi navigation systems were going to support this as well...as early as 1999 or 2000 in the US, but to my knowledge they're still not doing it; I have no idea about the euro units. I think it was mostly an infrastructure problem- either lack or incompatibility.

      Honestly, I question the value of such information in the first place. Rarely are other routes unblocked, at least here in Boston. You're pretty much screwed no matter which way you go. If that wasn't enough, they randomly close/open exits due to the massive construction(the Big Dig), and in the last 6-12 months, lots of big changes have been going on as new tunnels and exchanges open(which is going to wreak havoc with people with old databases for their nav systems!)

      • I think it was mostly an infrastructure problem-
        either lack or incompatibility.

        Umm, what other possible reasons are there? Maybe there was "too much" infrastructure for it to work?
      • i live in the seattle area, and this seems very useful. it is often the case that for the two bridges over lake washington (520 and 90 on the screen on the linked page), when one of them is clogged, the other is (significantly) less clogged. it's usually more often the case that 90 is less clogged than 520 than the reverse, but anyway, this device seems very useful.

        They are pretty much standard in the higher Audi models (A6 and A8) in Germany. I think they use extra information from radio programs, but I might be wrong. If there is a traffic jam somewhere, this is shown on the map the GPS unit displays, at least if it is on the highway. You can advise the unit to automatica

        I agree. My ideal navigation tool fits on my palm pilot, and has current public transportation tables. It should also tell me where I am, relative to the closest bus stop/transit center.

        In a city with enough pt, I could get by without my car entirely. As it is, I'm just too lazy to a.) find all the bus stops, and b.) memorize the route tables.

      This is really common in the UK - a company called TrafficMaster [trafficmaster.co.uk] gather data from their own network of sensors over most major roads in the country and make it available in a number of ways. You can get it off their website (with a sub), through a variety of standalone devices like the one in the article (except more flexible as they cover the entire network) or licensed to integrated in-car systems. My parents BMW has had TrafficMaster integrated into the GPS nav system for a good few years now - not only can it show you how to get somewhere it can find a quicker route if the traffic's bad.
      • And it wouldn't matter very much if the traffic's bad.

        Of course this doesn't help in the US where motorcyclists are not allowed to filter[1] through traffic, which partially explains the very low numbers of motorcycles on the roads in the US.

    I have one of these units thanks to an inside deal. I regularly use it to decide my route to work, and it has definitely saved me from sitting in traffic on many occasions.
    One thing to keep in mind is that Seattle is well suited for this device because of geography - there are no alternate routes. There are only the two east-west routes shown on the unit across Lake Washington. The north-south options aren't much better. You can't just swing over a couple of blocks to avoid a problem, so knowing that one of major routes is bad because of a wreck can make a huge difference.
    Traffic reports on the radio can help, but they always come on 30 seconds after you pass the decision point for which route to take. This solves that problem by keeping the last report handy for you at any time.
    The unit isn't perfect -
    (1) has a fixed configuration so it wouldn't be able to accomodate any new routes, but that isn't really likely to happen around here anyways. More lanes maybe, but no new routes.
    (2) It relies on the DOT data, which is occasionally of questionable accuracy.
    On the plus side -
    (1) it runs on the pager network so coverage is not a problem, neither are limits on data transfer or message counts over a cell network.
    (2) the price is reasonable enough that is easy to recover the monthly fee in time and frustration saved.

    Overall - don't even think of trying to take mine away!

    Just tune into traffic info radio or pick up your cell phone and call one of the many free traffic info services. Or, have the information sent to your cell phone. But most people realize pretty quickly that that kind of knowledge is pretty useless: even if 101 or 405 are stop-and-go, taking alternate routes probably still takes longer than just living with it.

    The only thing you can do is to stay a little longer at the office until traffic has died down. And to see when that has happened, you don't need a wireless gadget, you just point your desktop web browser at a traffic site.

    I wouldn't say that GPS units are worthless -- I just drove a system equipped with one a couple of weeks back and it was basically a wet dream.

    The input system was kinda clumsy, maneuvering a cursor around an alphabet to choose letters and numbers, but besides that I was in love with it. My parents were visiting San Francisco, and I live 30 min away in Belmont, so I had to take them around town and I am not too familiar with the city yet -- this thing made it a breeze.

    Basically it is Mapquest in your car. You input a destination and it tells you how to get there in the quickest way possible, then shows you on the map wherever you are at any point in the trip.

    When a turn is coming up, a pleasant female voice lets you know and then tones tell you exactly when to turn. If you get too far off the route that it planned for you earlier, it will plan a new route for you.

    This thing could have saved me sooooo much time in my life and it was really helpful. When I didn't need the voice I just turned it down and could check the display every now and then to prove that I was on the right course.

    If I had 2 grand to drop on it I would buy one tomorrow. If you're at all interested in GPS units for cars you can check it out at Hertz for a few more dollars a day.

    A cheaper solution is to hook up a handheld unit to a laptop. I know somebody who did that and got great results, a lot cheaper than 2 gs.

The WSDOT doesn't have the traffic monitoring systems set up anywhere else in the state. This isn't a navigation tool - it's a traffic monitor for the freeways. Useless, since you can get the same information every couple minutes on the radio

    I've had a system like this built in in my last 4 or 5 or is it 6 cars.

    http://www.trafficmaster.co.uk/

    Puts little road sign pictures up explaining what the delay is caused by, i.e. "Men at work" picture for roadworks, and how long the delay is expected. The Navigation unit takes this information and routes around the delay if necessary.

    I even posted a story like this the last time such a system was mention on /. {:-)

    On the one hand, it's a cool new gadget so men will buy it. On the other, it's like asking for directions so no man will buy it. It's kinda of a wash if you ask me.

    how about an 802.11b solution mixed with gps? send your current speed and location to other drivers. with enough of them the data would propagate through the network and even to the internet with strategicaly located access points. make the data available over the internet so your nifty navigation system can plot the fastest route based on distance and traffic. have it keep a log and you could predict the fastest route through a particular location in advance.
    • I have been thinking of building something similar for a few months.
      GPS not only gives you your position, but also synchronized atomic time. Hence a dense-enough network of cars with these units could accurately "map" the city's road in realtime. Data in a large Ad-Hoc network could "jump lanes" to the cars that require it - ahead, behind, even to the opposing lanes of traffic (which are more likely to carry routing information regarding your intended destination).
      Besides trip routing information, a lot of

  • Since now there is so much on board distraction (phone cell, video, dvd, gps mapper, and now this gizmo), I propose to patent the following : put a camera at the front of the vehicule and then put the output on a monitor which will be put in tzhe middle of all gizmo, so that the driver can STILL pay attention to where he is going... Hummm.... Wait a minute...

  • which will naturally never get off my arse to implement, was to create a GSM/GPS hybrid unit. It would function entirely like a standard GPS unit, except it could report back it's location and speed to a central server. The server could then distribute this information to other users of the system.
    e.g. If the speed of 10 users on a motorway suddenly dropped you could assume that there was a traffic jam. The unit could then calculate whether the journey of other motorists, whose route was along this motorwa
  • This is news?!? Japanese "car-navi" systems have had traffic analysis features for at least the year I've been here. At first I couldn't understand why they were so popular, but then someone explained why, in this country where street addresses are rare, best route analysis is a real plus to drivers. As the site is slashdotted I can't tell if the company is trying to sell this as a new thing, but it would be a shame if so. Oh yeah right, and "the Japanese are only good at copying American ideas."

    In sevreal european countries including Germany, The Netherlands and I believe also Austria, newer GPS-Travelpilot systems (2yrs+) are compatible with a system called TMC.
    It is based on, regional radio stations broadcasting a stream of digital data along with their regular audio programme. You don't hear it (just like you don't lear the RDS station identifier code) and you don't need to subscribe to anything either.

  • Is it worthwhile to have a single-purpose device like this? The Google-cached version of the product page indicates that it never needs to be turned off (so how fast does it go through batteries?) and that it is continually updated. I'm not sure that's enough to convince me it's a good idea. How much does it cost, for the device & for the subscription to the service? How often do you have to replace the batteries? What happens when it breaks -- would you even know until you're stuck in traffic when it c
  • "Now why can't auto makers put this kind of thing in a dash instead of mostly worthless GPS navigation and DVD units?"

    Because management gets confused when knobs from the west coast come over and tell us we need JAVA because a car is just a "browser on wheels" and other such crap. Then some other knob comes in with an OS that we'd have to pay for per unit... DVD players are essentially repackaged products, it's simple, but stupid.

    Does anyone know if this stuff can already be done with amateur radio? Could I build a radio transmitter and receiver, put up a big antenna or use a repeater, to transmit this information to myself in the car?
