Upcoming session

What Can We Learn from Fatal Automated Vehicle Crashes? A Closer Look at Crash Narratives in Media

Promo image for March 2023 CSCRS webinar

Date/Time: March 22, 2023, 2:30 – 3:00 p.m.

Presenter: Meredith King, Graduate Research Assistant – Transportation Engineering, The University of Tennessee, Knoxville

Description: Text mining tools allow for a deep dive into the language used in fatal crash narratives. This session explores key crash details that emerge from analyzing a unique dataset of news articles discussing fatal collisions involving one or more automated vehicles. The media dataset also provides insights into the survivability of the driver as a function of the crash details presented. The presentation will provide insights into the importance of analyzing narratives in media that shape public opinions about automated vehicle safety. Continued monitoring and analysis of automated vehicle crashes can help to inform future research and adoption of automated vehicles.

Peer Influence and the Perceptions of Safety

February 22, 2023

Presenter: Jill Cooper, Co-Director, University of California, Berkeley Safe Transportation Research and Education Center (SafeTREC)

Description: This session focused on a study examining the relationship between an individual’s perceptions of safety and those held by their peers using a survey that asked North Carolina residents a myriad of questions concerning transportation. Watch the recording. Slide deck.

This session was based in part on the brief “Peer Influence and Perceptions of Safety,” written by Cooper and Aqshems Nichols, CSCRS’s 2022 Student of the Year. The brief is based on research from the CSCRS project “Assessing how private beliefs conflict with public action on Safe Systems.”


Reframing Crash Reporting in News Media: A How-to Guide for Road Safety Professionals

January 25, 2023

Presenter: Elyse Keefe, Road Safety Project Coordinator, UNC Injury Prevention Research Center

Description: The ways in which news media frame crashes can have a significant impact on the public’s view of who is responsible, the motivation for making change, and beliefs about potential solutions. Unfortunately, research has found that reporting on crashes typically places responsibility on individual road users (particularly those on foot or biking) and frames crashes as isolated events. In order to build public knowledge and support for a Safe System approach, it is crucial that road safety professionals use effective messaging strategies to reframe crash reporting. The CSCRS media framing guide was recently updated to include step-by-step guidance, tips, and examples for professionals to help reframe the message. Watch the recording. Slide deck.

Case studies from across the U.S. on using systems thinking tools to inform Safe System partnership, strategic planning, and research

October 26, 2022

Presenter: Becky Naumann, Core Faculty at the Injury Prevention Research Center and Assistant Research Professor of Epidemiology at UNC Chapel Hill

Description: As communities across the US work to embrace Safe System principles, tangible tools and frameworks are needed to guide their planning, partnership, and implementation efforts. Additionally, tools are needed to help researchers study different collaboration models and pinpoint specific research needs for operationalizing a Safe System approach. This session will provide real-world examples illustrating systems thinking tools that transportation practitioners, researchers, and coalitions can use in their partnership development, strategic planning, and research to help with adoption of a multidisciplinary Safe System approach. Watch the recording. Slide deck.


Bringing development review into Safe Systems

September 28, 2022

Presented by: Jesse Saginor, Chair and Professor, Department of Urban & Regional Planning, Florida Atlantic University

Description: Traffic impact assessment (TIA) is an essential component of the land development review process across the US. Conventional TIA practices have long focused on identifying and mitigating the congestion impacts of new land development. Safety for road users is often a secondary concern and assumed incorrectly to be “taken care of” through congestion mitigation measures. This research explores the mental models behind this assumption, identifies opportunities to reconceptualize the role of land development in fostering safer streets, and advances a framework for centering road user safety in the development review process.

Introducing The first surveillance system for micromobility fatalities

August 31, 2022

Presented by: Kristin Podsiad, Dual Master of Public Health and Master of City and Regional Planning Student and Graduate Research Assistant, Highway Safety Research Center, University of North Carolina at Chapel Hill

Micromobility devices are increasing in popularity worldwide. However, because of the novelty of these devices, the fatality risk associated with these devices is unknown. This webinar will introduce the new website,, which aims to improve the tracking of fatalities involving micromobility devices, starting with e-scooter fatalities. Watch the recording. Slide deck.


Safe vehicles: How effective are pedestrian crash prevention systems?

July 27, 2022

Presented by: Asad Khattak, Beaman Professor and Transportation Program Coordinator, Department of Civil and Environmental Engineering, University of Tennessee, Knoxville

Description: In the drive toward safe vehicles, pedestrian crash prevention (PCP) systems have the potential to mitigate pedestrian crash severity or prevent crashes altogether. However, the reliability and effectiveness of these technologies have remained uncertain. This study explores the performance of PCP systems in field test situations to understand their effectiveness and how it varies among cars. Watch the recording. Slide deck.

This session highlights an effort to link creative placemaking techniques with traffic safety. Watch the recording. Slide deck.


Reports from the battle for the curb: Using social media to understand safety challenges faced by urban delivery drivers

March 23, 2022

Presented by: Evan Iacobucci, PhD, Postdoctoral Research Associate, Department of City and Regional Planning, University of North Carolina at Chapel Hill, and Dana Magliola, Statewide Program Manager, Freight + Logistics, North Carolina Department of Transportation

Description: Recent surges in urban freight delivery—largely driven by e-commerce and accelerated by the COVID-19 pandemic—have raised concerns surrounding impacts on safety, congestion, curb use, and unauthorized parking of freight vehicles. In this webinar, we highlight recent work that used online conversational data from Reddit to probe challenges delivery drivers face, with a specific focus on parking behavior. In particular, we discuss the implications that these behaviors—and the conditions that precipitate them—have for the safety of road users. Finally, we will discuss primary types of and reasons for unauthorized parking behavior, perceptions of parking enforcement, and interactions drivers reported with other road users.
