CALRoads View is an air dispersion modeling package for predicting air quality impacts of pollutants near roadways. CALRoads View combines the following mobile source air dispersion models into one seamless integrated graphical interface: CALINE4, CAL3QHC, and CAL3QHCR.
These US EPA models are used for predicting air pollution concentrations of carbon monoxide (CO), nitrogen dioxide (NO2), particulate matter (PM), and other inert gases from idle or moving motor vehicles.
Fully integrated interface combining easy to use graphical tools (e.g., roadway links, and receptors), seamless model run, and automated contouring and posting of results.
CALRoads View supports three US EPA traffic models in one seamless interface:, CALINE4, CAL3QHC, and CAL3QHCR. Change models in your project with the click of a button.
A wide range of contouring options and controls are available, making it easy to present your results just the way you want them
CALRoads View allows you to run a project with an unlimited number of receptors, avoiding the restrictions imposed by the models. You can specify a Cartesian receptor grid, discrete receptors, and receptors along the roadways.
CALRoads View offers the ability to model free-flow traffic, intersections, parking lots, street canyons, traffic patterns and different receptor configurations.
Rammet View, which is part of the CALRoads View package, allows you to pre-process meteorological data to be used with the CAL3QHCR model.
WRPLOT View, which is part of the CALRoads View package, allows you to create windrose plots for your meteorological data. Options to manipulate the appearance of the windrose are available such as colors, petal size, grid sectors, etc.
CALRoads View is an interface for the CALINE4, CAL3QHC and CAL3QHCR models. See below the technical specifications for these three popular traffic air dispersion models:
