Mass Motorization and Mass Transit examines how the United States became the world's most thoroughly motorized nation and why mass transit has been more displaced in the United States than in any other advanced industrial nation. The book's historical and international perspective provides a uniquely effective framework for understanding both the intensity of U.S. motorization and the difficulties the country will face in moderating its demands on the world's oil supply and reducing the CO2 emissions generated by motor vehicles. No other book offers as comprehensive a history of mass transit, mass motorization, highway development, and suburbanization or provides as penetrating an analysis of the historical differences between motorization in the United States and that of other advanced industrial nations.
