Google Maps with Real-time Traffic Info
Now if you are in San Francisco, New York, Chicago or any of the 30 major U.S. cities, you can get real time traffic information directly in Google Maps. 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. Pretty interesting to get to your rendez-vous in time. Via Google Blog
