So is this study. Read it, and I think you'll see why even conservative state governors want more and better public transit, not less. This argument is relied upon heavily by many conservative and libertarian critics of public transit. In fact, the real figure appears to be somewhat higher. But this paper argues that the central problem is not the answer but the question.
Total trips is a poor yardstick with which to measure the effectiveness of public transit.
If we ask what percentage transit carries of the trips for which it can compete, we get a very different picture, one that accords much more closely with the real importance of mass transit in urban areas. In each case, the system does far better than the transit critics suggest. Taken together, the three case studies establish beyond question that when we measure transit with the correct yardstick, transit competitive trips, transit works. The first recorded example of mass transportation was the movement of Adam and Eve from the Garden of Eden. In fact, according to most conservative studies of mass transit, it has gone straight down hill.
