Google is helping American holiday-goers in major cities avoid the heavy traffic jams by predicting the times when most cars will be out on the road. It’s set up a handy site where you can check the optimal time to drive into each city for your celebratory freedom fireworks.
To use the site, select your nearest metro area from the list and which day you plan to travel. Google will tell you the best and worst times to travel on that day.
