BREEZE ROADS contains several well-accepted dispersion models that vary in their applicability.
Includes similar model theory as is in CAL3QHC, but has an advanced method for calculating NO2 concentrations using the Discrete Parcel Method.
A roadway model that predicts air pollutant concentrations near highways and arterial streets due to emissions from motor vehicles operating under free-flow conditions and idling vehicles. In addition, CAL3QHC incorporates methods for estimating traffic queue lengths at roadway intersections.
An enhanced version of CAL3QHC, this version can process up to a year of hourly meteorological, vehicular emissions, and traffic volume and signalization data in one model run. In addition, 1-hour and running 8-hour averages of CO or 24-hour and annual block averages of PM can be calculated.
Due to the flexibility of BREEZE ROADS, users can enter model input data manually, by import, by pasting in table view, model object drag-n-drop, or point-n-click.
