|I JUST NOTICED TODAY that Google Maps has a new button: traffic. There, alongside the satellite and hybrid buttons. Whoa. How long has it been there?|
[UPDATE: At least since 9:01 this morning.]
Where does Google's data come from? Is it up to the minute? Why are parts of some freeways - the 2, the 110 - gray? No data?
This screen capture comes from 6:45pm on Wednesday, February 28, 2007. Other traffic services seem to report nearly identical rush hour conditions: highways 110 and 101 flowing blood red.
