Transportation System Safety is a Public Health Issue

Vision Zero is a strategy to eliminate all traffic fatalities and severe injuries, while increasing safe, healthy, equitable mobility for all. Its proactive, preventative approach prioritizes traffic safety as a public health issue in order to prevent traffic injuries and fatalities. However, crashes are often perceived as isolated incidents caused by human errors, rather than being viewed collectively. Examining the dynamics related to crash fatalities and severe injuries through a systems approach can enable identification of overarching safety issues and lead City of Boise to address systemic faults that result in negative outcomes.

Intersections are the main issue area for all fatal and severe crashes. Pedestrians are most vulnerable when crossing in a crosswalk at a traffic signal while bicyclists traveling with traffic and crossing at intersections are most vulnerable. Motorists experiencing fatal or severe crashes are generally traveling straight with inattention, alcohol impairment, and failure to yield being the greatest contributing crash factors. By examining these and other underlying issues associated with fatal and severe injury crashes, City of Boise can identify and address systemic transportation system faults and work to reduce and eliminate future crashes.
