JUDITH RAMOS VALENCIA
The history of the urban form of Los Angeles is tied to its transportation patterns, which was developed during the most important transportation revolutions:
1.- The first major transportation revolution was the Electric Streetcar Era (1890-1920)
2.- The second major transportation revolution was during the Freeway Era (1945-present).
Of all those issues we center our attention in the automobiles fuel use and the consequences that it brings to the earth and to humans.
