COMPREHENSIVE MODEL FOR THE PREDICTION OF AIR QUALITY ADJACENT TO URBAN EXPRESSWAYS

A comprehensive urban highway diffusion model termed CUES (Concentrations at Urban Expressway Sites) has been developed and successfully used to predict air quality in New York City. Unlike previous line source models, CUES is applicable to complex roadway configurations (combinations of at-grade, elevated and depressed elements) subject to arbitrary changes in alignment and extreme traffic loading. The model combines an analytical finite line source representation of roadway elements with statistical parameters obtained from a comparison of theoretical and measured concentrations. This approach results in a calibrated model capable of predicting future inert pollutant levels within an appropriately chosen statistical confidence interval for specified traffic, meteorology, highway configuration, and year of operation.
