I am pleased to present the California Department of Transportation (Caltrans), Division of Research, Innovation and System Information’s (DRISI) Annual Research Program Highlights. This report covers the 12-month period ending June 30, 2021, during which DRISI’s research program provided transportation solutions that addressed our customers’ needs and challenges. I like to think about DRISI as the Caltrans solutions lab or innovative think tank whereby we support the enterprise needs and strategic priorities.   

Thank you to our dedicated DRISI staff, Caltrans programs and districts, and the Research and Deployment Advisory Committee (RDAC) who made this report possible.

This report highlights many of our 196 active research projects supporting Caltrans’ mission to provide a safe and reliable transportation network that serves all people and respects the environment. Additional information about specific projects highlighted within these pages can be obtained by contacting any of the research staff identified in this report. For more information on our research efforts, visit DRISI’s website. I encourage you to browse the Research Notes and Research Results to find updates on topics of interest to you. Research Notes provide an overview of research in progress, while Research Results summarize completed research. Research Notes and Research Results have been written to make it easy for all to understand research.

There are multiple avenues for research to be conducted at the state or national level. I hope that as you read this Research Program Highlights report, you’re motivated to become involved in Caltrans’ research activities. Please contact DRISI staff if you have questions on the research process.
