| Stinking buses, their passengers pale
and tired, jam the crowded streets. Drivers shout at one another and honk their
horns. Smog smarts the eyes and chokes the senses. The scene is Athens at rush
hour. The city of Plato and Pericles is in a sorry state of affairs, built
without a plan, lacking even adequate sewerage facilities, hemmed in by
mountains and the sea, its 135 square miles crammed with 3.7 million pepole.
Even Athens’ ruins are in ruin: sulfur dioxiode eats away at the marble of the
Parthenon and other treasures on the Acropolis. As Greek Premier Constantine
Karamanlis has said, "The only solution for Athens would be to demolish half of

But bus ridership has declined from a peak of 11 billion riders per year in the late 1940s to 5 million in the 1990s. Commuter railroad service, like trolleys and buses, has also been drastically reduced in most U.S. cities.
The one exception to the downward trend in public transportation in the United States is the subway, now known to transportation planners as fixed heavy rail. Cities such as Boston and Chicago have attracted new passengers through construction of new lines and modernization of existing service. Chicago has been a pioneer in the construction of heavy-rail rapid transit lines in the median strip of expressways. Entirely new subway systems have been built in recent years in a number of U.S. cities, including Atlanta
