A MANUAL MODEL TO PREDICT HIGHWAY RELATED CARBON MONOXIDE CONCENTRATIONS
This paper is intended to present the derivation of the manual model used in predicting the region's highway related carbon monoxide concentrations and explain its use in predicting concentrations under different conditions. The model incorporates the variables of meteorology, involving both atmospheric stability and wind, vehicle mix by age and the associated vehicle miles traveled, vehicle type, distinguishing between light and heavy duty vehicles, carbon monoxide emissions by year modified by average link speed, traffic volume, measured for the peak hour and eight hour hourly average, and dispersion factors for both horizontal and vertical directions. With an accurate description of a facility's design, use characteristics and meteorological conditions, very accurate prediction of the carbon monoxide concentrations on or near the facility may be made. These variables and the derivation of the model are discussed in detail in the body of this paper, leading in logical order to the assembly and use of the model.
