On Thursday, April 28, 2022 the California Department of Motor Vehicles (DMV) held their R&D Bi-Weekly Brownbag seminar. The session included a presentation with SafeTREC Co-Director Offer Grembek, "Longitudinal Analysis Comparing Provisional and Final Crash Data in SWITRS."
In this presentation, Grembek discussed the principles and elements of the Safe System Approach, which is the new direction of California's Strategic Highway Safety Plan(link is external). The Safe System Approach aims to eliminate fatal and serious injuries for all road users through a holistic view of the roadway system.

Grembek also shared some preliminary findings about the implications of using provisional SWITRS data for analyses.
On April 21, 2022, the Institute of Transportation Engineers (ITE) San Diego Chapter(link is external) held their virtual April 2022 Luncheon, "Setting Speed Limits for Safety." The event included presentations with SafeTREC Co-Director Offer Grembek, "The Safe System Approach: Considerations for Speed Limits and Management" and with Zoubir Oudah, County Traffic Engineer with the County of San Diego, "AB443 - Setting Speed Limit to Enhance Safety."
Transportation safety professionals strive to build road systems on which no street user can be severely, or fatally, injured—a goal consistent with Vision Zero, which aims to eliminate traffic deaths. To accomplish such a safe system, it is necessary to effectively harness all the core protective opportunities provided by the transportation system. While many of these protective components are discussed in the academic and professional literature, the topic of safe speeds has always been the subject of much debate outside of professional circles. This presentation will discuss the relationship between traffic speed and safety, and why we need to reconsider current speed limit setting practices.
