The Safe System Approach (SSA) is central to U.S. transportation safety. While progress is underway, it is often siloed and reactive. On October 28, 2025 SafeTREC director Julia Griswold will present a poster at the 2025 AASHTO Safety Summit and Peer Exchange in New Orleans, LA that proposes a Unified Safe System Implementation Framework combining concepts from public health, context-sensitive design, and kinetic energy risk management to address this.
Former SafeTREC visiting student researcher and current doctoral student at UC Davis School of Medicine and Institute of Transportation Studies Katarina Cook will be presenting the poster "At the Intersection of Hit-and-Runs and Homelessness: Pilot Risk Analysis and Postmortem Case Series" at the American Medical Association (AMA) Research Challenge virtual symposim.
On October 23, 2025 SafeTREC director Julia Griswold will present in the "Telling Your Story: Crafting a Compelling Grant Narrative" breakout session as part of the 2025 California Active Transportation Program Symposium in Davis, California.
The Safe Transportation Research and Education Center (SafeTREC) is a multidisciplinary group affiliated with the School of Public Health and the Institute of Transportation Studies. Our mission is to inform decision-making and empower communities to improve roadway safety for all, with an emphasis on vulnerable road users in California. We achieve this by working with academics, government agencies, and community-based organizations. We currently have one position open. Please see the details below and upcoming review date.
On Wednesday, October 8, 2025, SafeTREC postdoctoral researcher Sujin Lee will present "Evaluate the effects of speed camera installation using telematics data in San Francisco" in the upcoming Metrolab Student Showcase as part of the Talk with the Experts Series. The webinar will showcase the groundbreaking research from the 2025 INRIX x MetroLab Challenge winners.

UC Berkeley’s Safe Transportation Research and Education Center (SafeTREC) has released the California Safe System Institute for Road Safety Executive Summary, highlighting findings from a statewide Needs Assessment conducted in partnership with Vision Zero Network and Fehr & Peers. Funding for this program was provided by a grant from the California Office of Traffic Safety, through the National Highway Traffic Safety Administration.
UC Berkeley SafeTREC and the Center for Pedestrian and Bicyclist Safety (CPBS), a Tier-1 University Transportation Center (UTC) supported by the United States Department of Transportation (USDOT) and led by the University of New Mexico (UNM), has released a Year 1 (2023-2024) research report titled "A context-sensitive roadway classification framework for speed limit setting in the US" authored by UC Berkeley's Julia Griswold, Cheng-Kai Hsu, Melody Tsao and John Bigham; University of Wisconsin-Milwaukee's Robert Schneid
UC Berkeley SafeTREC has recently released a new research brief titled "An Early Analysis of Speed Safety Camera Program Rollout in California" by former graduate student researcher Kyler Blodgett.

UC Berkeley SafeTREC has released the California Traffic Safety Survey 2025. The study was led by Ewald & Wasserman Research Consultants (E&W) and conducted on behalf of the California Office of Traffic Safety (OTS) and SafeTREC.
