Project Turns GPS Phones Into Traffic Reporters 119
narramissic writes "Starting on Monday, researchers from Nokia and UC Berkeley will kick off the Mobile Millennium project. The researchers hope that thousands of volunteers will download a free Java program that figures out by their movement and location when they are driving, and then transmits that information to the project's servers, which then crunch it into a Bay Area traffic map. 'The whole concept here is that if everyone shares just a little bit of what they're seeing ... then everyone can benefit by seeing the conditions ahead of them,' said Quinn Jacobson, a research leader with Nokia in Palo Alto."

I would imagine it wouldn't be too difficult for the system to recognize that certain senders are giving bogus data, especially if this became a big thing. You have to do things like that because even honest users will occasionally send bad data, either because their GPS gets a bad fix or because their car breaks down. Once the system realizes someone is sending bad data it can keep an eye on them. If they continue to send lots and lots of bad data then it just stops paying attention to them altogether.

Which was critical in the beginning when there weren't many Nav systems out there and wireless data service via cell phone wasn't a commodity.
The "chicken and egg" and "critical mass" problems are solved by combining traffic data from several different source, and getting a lot more data points than we would get if we only collected data from drivers who have a TomTom that's always connected to the internet with an unlimited data plan.
Sounds more like "were" solved; like I said before in the post you're responding to, this was probably a killer feature when there weren't many Nav systems out there.
The other question is how to TomTom users receive this real time traffic information. The TomTom devices that support HD traffic have their own cell phones with built-in SIM cards, whose cost is covered by the HD traffic subscription, so it can download traffic reports in real time. It does not require you to drain the batteries and increase the bill of your own cell phone. The TomTom device is usually plugged into the car charger.
