CALRoads View is an air dispersion modeling package for predicting air quality impacts produced by mobile sources at or near roadways and roadway intersections. Three US EPA models - CALINE4, CAL3QHC, & CAL3QHCR - are combined into one seamless graphical interface. These models predict air pollution concentrations of carbon monoxide (CO), nitrogen dioxide (NO2), particulate matter (PM), and other inert gases. » View more |
