Whether you're hitting the road Thanksgiving Eve or Black Friday, there's a good chance you'll run into some traffic with AAA projecting more than 43 million Americans to take a road trip this holiday. Fortunately, transportation analytics provider INRIX has data to pinpoint the absolute worst times to leave home.
Essentially, the numbers show that the later you wait, the more messy your commute is likely to be.
For those traversing Atlanta, Boston and Portland this holiday, 3 p.m. is the worst time to travel. The biggest impact during this time will be felt in Boston, where the average additional travel time is 24 percent and peak additional travel time will be as high as 43 percent, according to INRIX.
The average additional travel time in Atlanta and Portland is nearly even at 8.7 percent and 10.2 percent, respectively. However peak additional travel time in Portland is 34 percent, compared to just 17 percent for Atlanta.
For a majority of major U.S. cities, 4 p.m. will be the time to avoid. The list includes New York, Los Angeles, San Francisco, Washington, D.C., Philadelphia, Chicago, Seattle, Houston and San Diego.
Unsurprisingly, traffic will be the worst in New York, where the average additional travel time is 33 percent and peak additional travel time is as high as 56 percent.

San Diego will experience the least headaches, though, with an average additional travel time of just 8.9 percent and a peak additional travel time as low as 16 percent.
Outside of New York and San Diego, the average additional travel time in the aforementioned cities ranges from 12 percent to 22 percent, while the peak additional travel time ranges from 23 percent to 40 percent.
In Miami, drivers can expect the 5 p.m. hour to bring the most misery this Thanksgiving weekend, with the average additional travel time coming in at 26 percent and peak additional travel time at 42 percent.
"For consumers who want to spend the least amount of time driving to the malls, your best bet is to leave before 11 a.m.," INRIX senior economist Bob Pishue said in a statement. "Shoppers should avoid midday and early afternoon when travel times could be more than double their normal length."
