A record-breaking 46.9 million Americans will travel 50 miles or more away from home this Independence Day holiday, an increase of more than 5 percent compared with last year and the highest number since AAA started tracking 18 years ago. For the 39.7 million Americans planning a Fourth of July road trip, INRIX, a global transportation analytics company, predicts travel times in the most congested cities in the U.S. could be twice as long than the normal trip, with Tuesday being the busiest day.
