An urban diffusion model has been developed that uses urban transportation planning variables, such as speeds, volumes, and distances on network links, together with readily available meteorological data to forecast concentrations of carbon monozide in an urban area. The model includes a submodel that computes carbon monozide concentrations in urban street canyons, taking account of carbon monoxide. The model is particularly well suited to evaluation of the relative air pollution potential of alternative urban highway networks. It can also be used to evaluate alternative strategies for meeting air quality standards and to indicate sites for air quality monitoring stations. The model has been validated in a 2-year program that has included comparison of historical data from continuous air-monitoring stations and instrumented sites in St. Louis and San Jose. The model will be expanded to take account of other pollutants such as oxides of nitrogen. /Author/
