Description:
The U.S. Environmental Protection Agency (EPA) has been collaborating on a research project to investigate pollutant concentrations in a near-road environment. The first study city was Las Vegas with data collected from mid-December 2008 thru mid-December 2009. Roadside concentrations were monitored for particulate matter with an aerodynamic diameter less than 2.5 microns (PM2.s), criteria air pollutants, mobile source air toxics and black carbon. The objective of the research was to determine the variation in concentrations as a function of distance from the highway, including the analysis oftraffic data, and meteorological conditions. Roadside concentrations were monitored in Las Vegas, NV, along 1-15, at one location ranging from 10 to 300 meters from the highway. This one year long traffic study included real-time vehicular data, (flow, speed, and length), and continuous and semi-continuous meteorological and monitoring data. Utilizing existing regulatory tools the Motor Vehicle Emission Simulator (MOVES) model and the American Meteorological Society, U.S. Environmental Protection Agency Regulatory Modeling System (AERMOD) dispersion modeled concentrations
