Google Maps now shows traffic information. According to the official blog:
“For more than 30 major U.S. cities, you can now see up-to-date traffic conditions to help you plan your schedule and route.”
“If your route shows red, you’re looking at a stop-and-go commute; yellow, you could be a little late for dinner; green, you’ve got smooth sailing.”
Granted, this is probably more helpful for drivers, but some of you might find this helpful.
