Transportation The Nature of Things : Season 8 Episode 12

Are the problems of urban transportation insurmountable? The traffic jams which are a regular feature of city life make it appear so. This program examines the many cures being considered for the hardening of vehicular arteries: faster vehicles, mass transit methods, supersonic subways, bigger and better expressways, air transport, better control and direction of traffic. Over all this, however, lies a Malthusian gloom inspired by the population explosion of both people and automobiles.
