Safe System Approach

The Safe System Approach to road safety has proven to reduce traffic fatalities and serious injuries around the world. Safe systems principles are now being incorporated into traffic safety management throughout the United States. These principles correspond with the Toward Zero Deaths vision for zero fatalities on our nation’s roadways.

Everyone with a role in transportation shares in the stewardship of traffic safety. With the AASHTO Committee on Safety, Toward Zero Deaths is working to educate traffic safety and transportation practitioners on safety principle-based planning, design, construction, and operations.
