As the screen grab above for Chicago illustrates, the severity of current traffic conditions is shown using a green / yellow / red overlay in maps, satellite and hybrid views.
The same features have been available for select US cities on the Google Maps for Mobile application, so it's nice to see them port it to the desktop version for people planning their trips or checking the roads before heading home.
Let's hope we see this roll out to some of the other countries that now have street maps. Personally I vote for England and Australia ;)
