BREEZE - ROADS
BREEZE ROADS is an air dispersion modeling suite that predicts air quality impacts of carbon monoxide (CO), nitrogen dioxide (NO2), particulate matter (PM), and other inert pollutant concentrations from moving and idling motor vehicles at or alongside roadways and roadway intersections. ROADS can be used in conjunction with the MOBILE5 or EMFAC emission models or other emission data to demonstrate compliance with National Ambient Air Quality Standards (NAAQS), Federal Conformity Rules, the UK's National Air Quality Strategy, and modeling for highway site and design selection.

Overview

BREEZE ROADS contains several well-accepted dispersion models that vary in their applicability.

CALINE4

Includes similar model theory as is in CAL3QHC, but has an advanced method for calculating NO2 concentrations using the Discrete Parcel Method.

CAL3QHC

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.

CAL3QHCR

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.

Features

Key Features

  • 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

Basic Features

  • 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

CALINE4 Model

  • Calculates NO2 concentrations using the Discrete Parcel Method
  • Users may enter up to 15,000 sources and discrete receptors

CAL3QHC Model

  • 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

CAL3QHCR Model

  • 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
  • Users may enter up to 200 sources and up to 1,000 discrete receptors
