There are kinds of ways: a path for you to walk anywhere, a road for you or the car to follow, a highway for cars, a free way or expressway for your car to run at a very high speed, a street on whose two sides stands shops or houses, an avenue for you to enjoy space when driving, a freeway for you to drive with a high speed, a railway for a train and a subway for a train to runs underground. Track? Yes, there are signs that someone or some car has gone through it.
