To tell the truth, there is a few trains in Austin, so people in Austin who do not have cars mainly use buses to move around. It costs 1.25$ per one way, but if you are a student in University of Texas at Austin and have student ID card, you can go to everywhere in Austin for free by bus with it. We distinguish buses by their numbers from 1 through 983. The bus with number 20 go through airport to city, which means that you can get to inside of city from airport by using this bus with normal price. You do not need to reserve special buses or taxis to arrive to city. We also have Rapid bus, which are numbered 801 and 803. They run mainly on center street in Austin and come to each of bus stops in 10 minutes. They also can get to main places, so they are very useful.
