Google - The New Crowdsource of Traffic Data?
Yesterday on the Google blog, it was announced that Google is indeed tracking and analyzing the traffic patterns and movement info of the Google maps users when they opt to show their location to Google, and expanding it nationally to US highways and arterial roads when data is available. By analyzing thousands or millions of phones with map and posted speed limit data, they should be able to start to assemble a traffic picture that starts to build accuracy when overlaid on top of a base set of data (to fill in the gaps).
"When you choose to enable Google Maps with My Location, your phone sends anonymous bits of data back to Google describing how fast you're moving. When we combine your speed with the speed of other phones on the road, across thousands of phones moving around a city at any given time, we can get a pretty good picture of live traffic conditions. We continuously combine this data and send it back to you for free in the Google Maps traffic layers."
The crowdsource sharing capability is available on the MyTouch 3G and the PalmPre; not the iPhone which doesn't support the crowdsource feature. See the Google Blog post for more information and a way that you can opt out if the whole idea of being anonymously tracked by google freaks you out too much.
