Advancing Transportation Safety Using a Public Health Approach: The North Carolina Vision Zero Collaborative Support Model

Le résumé fourni par la source

CONTEXT: Vision Zero (VZ) is a road safety initiative that seeks to address the problem of road fatalities using a Safe System approach, a holistic endeavor embedded in public health principles that seeks to build layers of protection across transportation systems to eliminate road fatalities and serious injuries. Since 2020, a multidisciplinary research team established a statewide collaborative to support communities pursuing VZ initiatives across North Carolina. PROGRAM: The North Carolina VZ collaborative "support model" was created to meet the need for community-based, multisector efforts using a Safe System approach. The support model aims to increase community capacity to more effectively build cross-disciplinary coalitions, pool needed resources, and strengthen adaptive leadership skills to reduce roadway fatalities. IMPLEMENTATION: The support model approach is used to engage communities in building skills in cross-sector collaboration, adaptive leadership, and evidence-based safety procedures. This is accomplished through structured monthly touchpoint meetings with small groups of community partners for peer learning, quarterly "all-hands" meetings to coordinate efforts across the state and provide resources, and an annual team-based multiday Leadership Institute. EVALUATION: From 2020 to 2025, there was notable growth in community participation, from 7 to 33 communities. Of communities with more than 1 year of participation (n = 19), more than half advanced VZ implementation with communities moving from an exploration stage to an installation (n = 8) or initial implementation (n = 2) stage. In 2023, interviews with partner community leads (n = 15) indicated that partners utilized resources provided, applied skills they learned at the Leadership Institute, benefited from the peer network, and identified opportunities for increasing the benefits of the support model. DISCUSSION: The support model demonstrates a promising practice for increasing capacity building and cross-sector collaboration for road safety initiatives requiring complex systems change such as VZ.
