Google Maps now displays traffic on city arterials:
More amazing is the crowdsourcing technique Google is using to capture congestion data:
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. It takes almost zero effort on your part — just turn on Google Maps for mobile before starting your car — and the more people that participate, the better the resulting traffic reports get for everybody.
This is brilliant. Now all you need are geo-located Google/Twitter feeds for drivers to explain why they are stuck in traffic.
