Estimates of pollution from U.S. nonfreight highway transportation.

Forecasts to the end of the century on the future use of resources and the future generation of various pollutants as a result of different proportions of the use of private automobiles and public transportation are made. The effects are extended to supporting industries such as steel, cement and coal. Relative transportation pollution costs for an urban area are modelled. It is shown that even a 50% diversion of automobile commuting to bus commuting would not have a dramatic effect on overall resource utilization and pollution, but would have a marked effect on the heavy pollution costs of central cities. A system of road-use charges is proposed. [ABSTRACT FROM AUTHOR]
