Google Maps added a new traffic information feature that will benefit drivers: Google will predict traffic conditions based on local reports.
When you visit Google Maps, you will see a new button named “Traffic” along with “Street View”, “Maps”, “Terrain” and “Satellite” images.With this traffic feature, Google will provide real-time traffic information.

Here is an example that shows New York traffic.
Google Maps will provide this traffic data in 30 major cities in the U.S. such as Los Angeles, New York, Chicago and other areas.More cities and countries will be added in the near future.
