MEXICO CITY METROPOLITAN AREA CASE STUDY.

Over the last fifty years Mexico City has grown from a pleasant city with a population of a million people to a sprawling megalopolis of almost twenty million. This has brought many problems of which one of the most important is that of transport. The metropolitan area extends across parts of two distinct, self-governing, administrative areas (the Federal District and the State of Mexico). Whilst these are physically contiguous they have very different policies and resources leading to different standards, costs and varieties of transport. Dealing with the economic, environmental and transportation problems of continuing population growth, with severely limited resources, is the major challenge for the management of the metropolitan area of Mexico City.
