Community Pedestrian and Bicycle Safety Training Program

The Community Pedestrian and Bicycle Safety Training (CPBST) program is a joint project of UC Berkeley SafeTREC (SafeTREC) and California Walks (Cal Walks). The Community Pedestrian and Bicycle Safety Training Program (CPBST) works with local residents, agency and organization staff, and transportation safety advocates to understand a community’s walking and biking safety concerns and advance their pedestrian and bicycle safety goals. We work to strengthen collaboration between all safety...

Comunidades Activas y Seguras (Active and Safe Communities) Program

Comunidades Activas y Seguras (Active and Safe Communities) is a joint program of UC Berkeley SafeTREC (SafeTREC) and California Walks (Cal Walks). After working with communities of diverse backgrounds through our statewide Community Pedestrian and Bicycle Safety Training program, we decided to create a curriculum tailored to better meet the needs of Spanish-speaking communities. Since its inception in 2021, Comunidades Activas y Seguras (CAyS) has been dedicated to enhancing walking and...

Community Pedestrian and Bicycle Safety Program

The Community Pedestrian and Bicycle Safety Program (CPBSP) was launched by UC Berkeley SafeTREC (SafeTREC) in collaboration with California Walks (Cal Walks) to reduce pedestrian and bicycle fatalities and serious injuries in communities across California. The CPBSP prioritizes working in communities that are at disproportionate risk for road traffic injuries and addressing the safety needs of people who are underserved by traditional transportation resources and planning, e.g., older adults,...

SafeTREC's Griswold to present on Unified Safe System Implementation Framework at 2025 AASHTO Safety Summit

October 13, 2025
Submitted by Lisa Peterson

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. The matrix links SSA elements to...

Pairing Speed Limit Reductions and Infrastructure to Lower Fatal and Serious (FSI) Crashes

2025

While recent California legislative reforms grant jurisdictions greater flexibility to lower speed limits, evidence suggests that reductions in posted speed limits alone are insufficient to meaningfully reduce crash severity. This research brief examines how speed limit reductions, when paired with infrastructure design, enforcement strategies, and contextual land-use planning, can more effectively lower FSI outcomes. Aligned with the Safe System Approach, the countermeasure layers of roadway geometry, lighting, bicycle-specific infrastructure, and enforcement shape driver behavior and...
