The purpose of this study was to increase understanding of Traffic Safety Culture (TSC) by identifying its constituent components. A review of existing safety culture literature was conducted. Next, 18 international experts participated in a Delphi Technique to rate candidate TSC components. Corresponding survey items were then developed and pretested. The final survey instrument was mailed to a representative sample of 1700 U.S. households. Their data were used to conduct a Factor Analysis that yielded a 15 factor structure. The factors that explained the most variance in TSC were support for increased government attention to traffic safety, strict monitoring and control of alcohol-impaired drivers, disapproval of speeding, and avoidance of aggressive driving. Other factors included local engagement, desire for government & private sector accountability, more information, school involvement, teen restrictions, willingness to invest and seatbelt use. This work represents a first attempt to operationalize TSC. Future research will be needed to refine and extend the tentative structure that has been identified. Valid and reliable measurement of this construct should facilitate traffic safety advocates’ efforts to overcome the social challenges they face.
