BREEZE ROADS allows your productivity to skyrocket because it uses a streamlined approach. Whether you're entering links or receptors, you enter it only once. What's more, you can visualize your project right on your computer screen, allowing you to easily quality check your data and see your work. There is no better software tool to simplify this aspect of your job.

  • Estimate total air pollution concentrations from both moving and idling vehicles
  • Estimate queue lengths at intersections and the contribution of emissions from idling vehicles
  • Incorporate saturation flow rate, signal type, and arrival type data for intersection assessments
  • Calculate pollutant concentrations on at-grade roadways, depressed roadways, raised roadways, bridges, intersections, street canyon and bluffs, and parking structures
  • Includes the CALINE4, CAL3QHC and CAL3QHCR line source dispersion models and a traffic algorithm for estimating vehicular queue lengths at signalized intersections
  • Calculate concentrations from historical hourly or user-specified meteorological data
  • Specify traffic and signalization data with up to seven different patterns
  • Distinguish between an urban or rural location
  • Import AutoCAD.DXF files, aerial photos, or other basemaps (.BMP files)
  • Create report-quality 2D, top-down, and 3D graphics
  • Create concentration contours using the enhanced output
  • Calculates NO2 concentrations using the Discrete Parcel Method
  • Users may enter up to 15,000 sources and discrete receptors
  • Predicts air pollutant concentrations near highways and arterial streets due to emissions from motor vehicles operating under free-flow conditions and idling vehicles
  • Incorporates methods for estimating traffic queue lengths at roadway intersections
  • Users may enter up to 120 sources and up to 200 discrete receptors
  • An enhanced version of CAL3QHC
  • Ability to process up to a year of hourly meteorological, vehicular emissions, and traffic volume and signalization data in one model run
  • Calculates 1-hour and running 8-hour averages of CO, or 24-hour and annual block averages of PM
