Caltrans Air Quality Research
Division of Research and Innovation


The Caltrans Division of Research, Innovation, and System Information (DRISI) (Division of Research and Innovation [DRI] - before 2012) manages most formal research for the Department, and is the official descendant of the research program formerly carried out by the Transportation Laboratory. DRISI's research is usually done through University Transportation Centers, national engagement processes, contracts, and other programs.

Several air quality-related projects have been done since about 2006 through DRISI, with the University of California, Riverside (UCR) and several other groups. The main DRISI website provides access to status information for ongoing studies and published products from past studies.

Work done by DRISI related to air quality may be sponsored by a variety of sources. However, most recent work has been sponsored by either the Transportation Planning or Environmental Analysis Divisions. Work listed here is primarily from those two sources.

As with most materials at the Caltrans web site, materials here are Copyright © by the State of California. Please contact Caltrans for more information before republication or other reuse.
