New GPS Navigator Relies On 'Wisdom of the Crowds' 90

Posted by Zonk from the you're-always-guided-using-renraku-gridguide-system dept.
Hugh Pickens writes "The New York Times is running an article on Dash Express, a new navigation system for automobiles that not only receives GPS location data, but broadcasts information about its travels. Information is passed back to Dash over a cellular data network, where it is shared with other users to let them know if there are slowdowns or traffic jams on the road ahead. The real benefit of the system isn't apparent until enough units are collecting data in a given area - so Dash distributed over 2,000 prototype units to test drivers in 25 large cities."

    Come on, this isn't the "Wisdom of Crowds". This is just collecting and organising a lot of information from asked from different people. We should keep the "Wisdom of Crowds" tag for times when knowledge or decisions spontaneously emerge, otherwise it'll become another meaningless buzzword.

    • The ones that aren't transcend the buzz with the passage of time. But I hear you, it can be painful.
    • Agreed. And this isn't something new. The two major road data providers, TomTom and Tele Atlas, already have their "crowdsourcing" tools to improve the maps of their GPS Nav systems (and any other other of their customers, such as Google, Microsoft and Yahoo!). See MapShare [tomtom.com] and MapInsight [directionsmag.com], their official tools. Of course, OpenStreetMap [wikipedia.org] is could be considered another pertinent project bridging GPS and crowdsourcing. Oh, and by the way, you have real-time traffic in Google Earth [blogspot.com] too you know. And we discussed p2p networks for road traffic [slashdot.org] some time ago.

      And now, totally off-topic, I would have liked /. to discuss the last Microsoft Virtual Earth release this week [slashdot.org]. It's really major. My story submission about it was rejected. There's even a Google SketchUp competitor in there and many features we won't see anytime soon on Google Maps / Google Earth (and other few worthy competitors).
      • Humm.. that was too early in the morning. Of course, Tele Atlas' competitor is NAVTEQ [gpsreview.net], not Tom Tom. If I'm not wrong, NAVTEQ is bigger. It has been bought by Nokia last month. While Tele Atlas was bought by Tom Tom themselves earlier last summer, so it shades a new light on my parent post. I don't think NAVTEQ have any "crowdsourcing" type of GPS/Road data tool yet.

You could also train a neural network to give you better travel times. Perhaps not so much the "wisdom" of the crowds as it is the "experience" of the crowds. But it is valid, and it could be quite useful.

For instance, if the police are chasing a vehicle, they can have OnStar disable it, which turns it down to idling speed, forcing (or allowing) it to pull off the road. Of course, they plan to have some common sense restrictions: police cars will need to be near the vehicle before they cut the gas.

    Here's a counterpoint [amazon.com]. While this is not really a "wisdom of crowds" application (being rather just a mass data aggregation scheme), it's worth noting that crowds are prone to fads and other mistaken behavior. Mass decision-making seems to work best with unconscious decisions, choices that everyone makes but does not think about a whole lot.

    I could see this system working, though, at least reasonably well. If I see a lot of GPS units going to a particular area, and then slowing down and stopping, I might want to avoid that area. Unless, of course, I'm on the way to a football game or something like that. :-)

    I had an idea similar to this last year, but I wasn't planning on transmitting data through the mobile phone networks as that could get costly. I thought that each unit could automatically connect to any open wifi network and download the traffic information for the whole country, much like this one sounds like it does. But, when units pass each other on the road, then they should compare time stamps and then update each other to the newest copy. At that point they could also update each other on slow downs and where they happen, as well as slow downs taken from other units as they passed. This would avoid the expense of a mobile network and the risk of a centralised collection of data.

    I currently have one of the mentioned Garmin units here in the UK that uses FM bands to pick up traffic information. The biggest problem is only the major routes are updated, and even then are sometimes missing traffic jam information.

    This unit does sound very good though, and I look forward to getting my hands on one.

    • What you described is called "Jousting": using automotive GPS devices to track traffic speed, and exchanging traffic information via WiFi P2P networking with oncoming traffic, who just drove by where you're heading. A GPS device with a WiFi antenna pointed forward in the direction of travel can exchange real time traffic information with oncoming traffic, that just drove past the traffic ahead of you in the opposite direction. Jousting takes advantage of the natural flow of traffic to distribute real time

  • Why dont these companies use mobile phone data to update this information? Eg mobile phone companies can track how many phones are at a certain location. The more mobile phones are at a certain location (even speed could be measured) to more likely there are traffic jams.

    To do this on your own (nav comapny) is just plain inefficient.

    and

    "Dash's outgoing information is sent over a cellular data network, which is also used to receive things like minor software updates and traffic alerts. Large amounts of data, like major map revisions, come through the Dash's built-in Wi-Fi receiver. The unit will automatically spot open Wi-Fi networks and connect."

    Finally,

    "The prospect of a G.P.S. unit continuously reporting a car's speed and location gives some drivers the willies, but Ms. Bender said that the information was sent anonymously -- there was no way to know which car it came from. If the unit is stolen, the company can send a signal to erase its memory, including driving data and the address book, so that it can't be extracted."

    Hopefully your unit will not be stolen while you've parked your car overnight, or even for a hour, so you'll have time to get them to send the kill code before the unit is compromised.

      • In case of theft, there needs to be a way to add information to the system so that a particular signature is no longer anonymous but

I don't care if the police bust down doors, listen to phone calls, read e-mails, etc... as long as they have a very good reason to suspect the person of wrong doing, and they went through a judge and have the legal authority to use these systems.

It makes there job easier and safer, and hopefuly makes the world safer.

Once a threshold is reached, the company can convert the raw GPS data into map data, then push out a map update with the next sync.
