Today´s need for balanced urban transit systems

Cities must have freeway systems in order to facilitate the movement of traffic. After a city reaches a certain size, however, it soon becomes apparent that freeways alone cannot solve the transportation problem. The only solution to this problem is to provide a system of balanced transit. Thus every large city that has expanded very rapidly¿Los Angeles, Houston, Atlanta, and many others¿should be planning or building a balanced transit system, with railroad rapid transit (including suburban railroad service) as the core, augmented by freeways for buses and private automobiles.
