Dispersion Modelling of Traffic Related Pollutants from Highways

Abstract

In this paper, we use the CAL3QHC air dispersion model to predict the concentration of air pollutants of interest at desired locations. We utilize the U.S. Environmental Protection Agency (EPA) Motor Vehicle Emission Simulator (MOVES) to generate the emission levels used in our analysis. Using the output from the air dispersion model, we will develop site-specific emission information. This information will be used to map out the vertical and horizontal placement of the sensors for optimal sensor deployment. The deployed sensors will be used to monitor the concentrations of traffic related pollutants near highways in real time.
