There is growing interest in “traffic safety culture” (TSC) as a key factor to manage and sustain safe roadway transportation systems, especially as more jurisdictions adopt targets of zero traffic fatalities and serious injuries. However, the theory, terminology, and methods involved in addressing TSC come from human and social science disciplines that are not always familiar to traffic safety agencies (e.g., departments of transportation, driver’s licensing, motor vehicle records, etc.). The lack of shared language and understanding about TSC limits the ability of agencies to explore this topic and engage new stakeholders. Additionally, the variation in the interpretation and implementation of TSC strategies has resulted in a lack of consensus about best practices. Communication tools that develop shared language and understanding about TSC and its relationship to vision zero goals are needed. This webinar will summarize the TSC Primer and its supporting toolkit that have been developed to address this need as part of a multi-state pooled fund project.
