Step 1 : Introduction to the question "What is the average length of a Thanksgiving long-distance trip in the U.S.?"
...People traveling to get to family and friends over the Thanksgiving holidays increases by as much as 54 percent over the travel distances for the rest of the year. The U.S. Department of Transportation lists the average Thanksgiving trip to visit family and friends at about 214 miles long. It is one of the top three holidays for traveling. Each year, more than 40 million Americans are driving 50 miles or more to spend time with family and friends. This is also the time of year when more traffic accidents occur, so remaining vigilant while on the road is an absolute must. Source: JBLE.AF.mil
