New GPS Navigator Relies On 'Wisdom of the Crowds'
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.
Maybe a wisdom-of-crowds GPS system would help you follow all the traffic if you get lost, under the assumption that everybody else probably knows where they're going.
before users get a button to press when they see a speed trap? If enough users report a speed trap at a given intersection or off-ramp, the system could issue an alert to other drivers approaching the area. People would love 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.
Everybody is now going to freak out about the "privacy issues".
A) The device supposedly transmits the data anonymously
B) Nobody is forcing you to get it
C) You probably aren't interesting enough to bother watching
Now, privacy concerns are valid and good. I don't want a "big brother" state as much as the next guy. However, how much are we going to let "privacy" get in the way of innovation? Think about how valuable this could be if everybody did have it? Think about the time saved, the gas saved, and possibly even the lives saved. I'd love to know if there is deadlock traffic ahead that I can't see, and I'm still cruising along at 60+ mph.
Now, as far as the privacy goes. I wouldn't even mind if this could be used by law enforcement to catch criminals. What we need is a way to limit when systems like this good be actived. 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. If there is some good evidence that a person minght be a criminal, I'd love for the police to have every bit of possible information on that person. It makes there job easier and safer, and hopefuly makes the world safer.
We don't need to worry about the technology. We need to worry about the laws that congress passes, and the things that our govenment does that bypass a good solid legal proccess. There are plenty of gadgets in our lives that can be used against us to limit our privacy. That part is done and over. What we need to be conerned about is the actual legal basis for when the government can access those devices. So, before you post about how big brother is going to watch your car, think abougt writing your congressmen instead. Let them know what you think.
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 and MapInsight, their official tools. Of course, OpenStreetMap is could be considered another pertinent project bridging GPS and crowdsourcing. Oh, and by the way, you have real-time traffic in Google Earth too you know. And we discussed p2p networks for road traffic some time ago.
/. to discuss the last Microsoft Virtual Earth release this week. 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).
And now, totally off-topic, I would have liked

Speaking as a truck driver I can tell you that CB-Radios already do this.
"Hey North-bound, you better get your ass off that road and find a detour, there's a 3 mile parking lot ahead of you."
"10-4 South-bound, thank-you. There's a Bear with a radar-gun at mile-marker 127."
Just add more profanity and you get the general idea.
