CALRoads View is an air dispersion modeling package used to predict air quality impacts near roadways from both moving and idling vehicles. Three dispersion models are integrated into the application: CALINE4, CAL3QHC, & CAL3QHCR. The original design of these models accounted only for releases of particulate matter (PM), carbon monoxide (CO), or nitrogen dioxide (NO2) with no further support for other inert gases.
There are many reasons why it may be necessary to create a copy of a modeling project. You may want to make edits to a scenario without overwriting previous results, or you need to re-run the project using a different set of meteorological data while maintaining the rest of the inputs.
CALRoads View is Lakes Software’s interface for handling the CALINE series of air dispersion models. Used for assessing air pollutant concentrations from on-road emissions of motor vehicles, CALRoads View includes three models: CALINE4, CAL3QHC, and CAL3QHCR.
Lakes Software’s commercial applications all feature a similar look and feel. This familiarity allows users to easily execute a variety of air dispersion models even when accessing a brand-new product for the first time. The image below uses AERMOD View to demonstrate the key components of each Lakes Software application.
CALRoads View includes three mobile source air dispersion models: CALINE4, CAL3QHC, and CAL3QHCR. These 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 vehicles.
CALRoads View makes it very easy to input links to a modeling project using one of the CALINE series of models (CALINE, CAL3QHC, CAL3QHCR). While it’s common to graphically depict links, CALRoads also allows modelers to import links using an Excel spreadsheet template. This is useful for modelers who have all of their inputs defined or those who have a lot of data to input. The template spreadsheet is found in the C:\Lakes\CALRoads View\Templates folder.
