Google Maps for mobile expands traffic coverage

Google announced it will extend its Maps for mobile traffic coverage to include all U.S. highways and arterials as part of an ambitious crowdsourcing effort to help drivers more efficiently reach their destination and influence legislative road planning decisions. According to Google, mobile users who choose to enable Google Maps with My Location send anonymous bits of data relaying updates on how fast they’re moving – Google combines that information with the speed of other phones on the road, collecting information from thousands of devices in the vicinity to create a portrait of live traffic conditions. That information is continuously combined and transmitted back to users in the Google Maps traffic layers. (more at Fierce Mobile)

I’ve been testing Google Maps while travelling in France, and it was pretty accurate in giving traffic conditions for the main axes.
