International Journal of Environment and Pollution (IJEP), Vol. 44, No. 1/2/3/4, 2011

Abstract: The relative performance of two atmospheric dispersion models STREET and OSPM is assessed using measured CO and NO_x data obtained adjacent to an urban street canyon. This paper in particular, evaluates the performance of STREET, a mathematical model, to determine its suitability as an alternative to the OSPM model, which is a more elaborate numerical model. The performances of the models are tested using composite emission factors calculated as per the speed conditions present on the study site. Two different versions of CEF were used depending upon the speed of the vehicles during daytime and nighttime.
