COMPARISON OF INTERSECTION AIR QUALITY MODELS' ABILITY TO SIMULATE CARBON MONOXIDE CONCENTRATIONS IN AN URBAN AREA

In support of an environmental impact statement for a major transportation project in New York City, an air quality study was undertaken to determine model performance of intersection air quality and to ascertain which model should be applied for impact analyses for this project. Instruments were set up at six intersections to measure carbon monoxide concentrations and meteorological data. Traffic data were collected by videotaping. To date, results from two of the six intersections have been analyzed. Model performance was disappointing. Correlation coefficients of observed to predicted concentrations were low (generally less than 0.1), as were the slopes of linear best-fit curves. The models, on average, underpredicted observed concentrations, with only those models that separate composite emissions into their more discrete components indicating a potential for approaching or overpredicting observed carbon monoxide levels.
