Many people are in love with their private autos, which fits with their house in the suburbs that they oppose the using of transportation dollars for any other purpose than streets and highways. Many others have no choice because there is no public transportation. The result is that there are more cars than will fit on the roads, a fact that is evident to anyone who has to use I-35E during the rush hour. Improvements to this corridor would cure the problem if they had been made today, but when they are finished they will already be inadequate. Denton County has just bought into the idea of a rail system that will patch into the Dallas system. Will it eliminate traffic jams along I-35E? No. The question is, however, what can we do instead? The answer is: Not much.
Our personal experience with trasnportion in Germany showed us that given a choice people will prefer the privat Auto every time, but that a very high use of bus and rail, which takes pressure off the road net, is possible. Will it may for itself? No, but neither does the private car.
