Media Narratives of Pedestrian & Bicyclist-Involved Crashes

May 20, 2020

UC Berkeley SafeTREC is excited to share a new research highlight by graduate student researcher Marta Polovin, "Media Narratives of Pedestrian & Bicyclist-Involved Crashes."

New research highlight focuses on how media and popular discourse factor into traffic safety perspectives and outcomes. Pedestrian & bicyclist-involved crashes have been increasing throughout the United States. Previous research has shown that media and popular discourse disproportionately blames pedestrians and cyclists for their own injuries and/or deaths, while obscuring the role of motorists in these...

New resource: CPBST Program Workshop Follow-Up Survey Highlights
