CAL3 Interface Web Conference. The Air Quality Technical Service Team of the FHWA Resource Center has designed and constructed an easy-to-use interface for two highway air quality models - the Environmental Protection Agency's (EPA) California Line Source Dispersion Model (CALINE3) for freeways and CAL3QHC for signalized intersections. The new interface includes interactive graphical forms for entering the required data, organized by commonality: 1) control data; 2) receptor data; 3) link data; and 4) meteorological data. Plus, it allows the models to operate on the Microsoft Windows operating system by providing modes for program execution; displaying results in a summary table, bar graph, or model printout; and opening, saving, and printing data files. A web conference will be held Wednesday, September 14 from 1:00 - 3:00 EST (10:00 - 12:00 PST) to explain how the interface functions. The session is limited to the first 15 registrants. Register now at : For more information, please contact Michael Claggett at The Instructions for participating in the web conference and downloading and installing the software will be sent to registrants.
