Traffic and Emission Inventory using Moves 2010 (Motor Vehicle Emissions Simulator) Applied to El Paso Juarez Airshed

Ground level pollution is a continuing environmental concern in several U.S cities.  A necessary step towards understanding and quantifying the problem is the implementation of simulation models that can provide an accurate estimate of emissions from mobile sources. Approach developed in this research improves the ability to fast predict emission variation from traffic control measurements, estimate county level inventory of criteria air pollutants, greenhouse gas emissions, and some mobile source air toxics from highway vehicles is  applied in the El Paso Texas Airshed using MOVES 2010 ( Motor Vehicle Emissions Simulator 2010). The purpose of the tool was to provide an accurate estimate of emissions from mobile sources under a wide range of defined conditions. In the modeling process, are specified vehicle types, time periods, geographical areas, pollutants, vehicle operating characteristics, and road types to be modeled. The model performed a series of calculations, which have been carefully developed to accurately reflect vehicle operating processes, and provide estimates of bulk emissions or emission rates. Was selected the appropriate months for the pollutant being analyzed, i.e., the summer ozone season for NOx and hydrocarbons and the winter CO season, where events occurred very high peaks. This study will have an impact in pollution control strategies over numerous U.S regions which are in non-compliance with U.S Standards for ozone concentration.
