What is Advancing Transportation Safety?

Advancing Transportation Safety (ATS) is a statewide collaborative effort led by a team of state and local agencies, advocacy groups, academic institutions and private entities.


The ATS initiative was developed as part of the implementation efforts for the 2020-2023 Strategic Transportation Safety Plan, required by the Highway Safety Improvement Program (HSIP) and is a natural evolution of the Moving Toward Zero Deaths endeavor that began in 2015. The plan identified the need for a coalition that could advocate for transportation safety with a unified voice and develop a coordinated approach to address key transportation safety issues in Colorado. ATS and its many partners endeavor to make a long-term investment in and commitment to transportation safety across Colorado (Strategy B), to cultivate a robust transportation safety culture and to ultimately reduce fatalities and serious injuries for all users on Colorado roadways.
