Think of automobiles and the image of a gas guzzling, be-finned monster of the road comes to mind. It is upon this image that this book is based. It is the third, and last, in a series from the authors. The first, cities and Automobile Dependence was published in 1989, followed in 1999 by Sustainability and Cities; Overcoming Automobile Dependence. The authors draw from a long-standing and broad dataset, developed by them and known as the Global Cities Database. The earliest data goes back to 1960 and runs up to 2000, and it draws on information from 26 cities across the world. Of particular interest to the authors is the growth of 'vehicle-kilometers-travelled (VKT)', a key factor which increased steadily over the first 40 years of the database records and is now reducing.
