A description of the California Line Source Dispersion Model, CALINE4, is given. The model uses traffic emissions, site geometry and meteorology to predict air pollutant concentrations near roadways. Predictions can be made for carbon monoxide, nitrogen dioxide and suspended particles. Options for modeling near intersections, parking lots, elevated or depressed freeways, and within canyons are given. A modal emissions model developed for the CALINE4 intersection link option is described. Also, an adjustment for transient emissions is developed. Computer documentation and user instructions for CALINE4 are included in the report.
