My freelancer wrote these two sentences. I know they are correct because I saw other natives use "travel" like he does. According to the dictionary, in the first sentence, "travel" means the activity of traveling. My question is why the activity of traveling is a mode of transportation. I don't understand the use of "travel" in the first sentence.
Car travel was the most frequently used mode of transportation in both years.
Does "travel" in the second sentence have a different meaning? Does it mean the distance that an object moves?
Car travel had increased to 4,806 miles by 2000.
