Strategic Transportation Safety Plan

2014-19 Colorado Strategic Highway Safety Plan

Colorado’s past Strategic Highway Safety Plan (SHSP) built on the success of the past and the state’s previous Strategic Plan for Improving Roadway Safety (SPIRS) adopted on October 1, 2006. This SHSP provided innovative, data-driven approaches to address issues that impacted traffic safety including emerging issues such as the change in Colorado’s marijuana laws. The SHSP drew on the experience, knowledge, and expertise of a multidisciplinary group of government agencies and private sector organizations, for the first time committed to the TZD goal, and relied on their continued commitment and tireless efforts to work toward a collective goal of Moving Towards Zero Deaths.

2020-23 Colorado Strategic Transportation Safety Plan

The Strategic Transportation Safety Plan has been updated for 2020 to 2023. It is a statewide plan, intended for all Colorado stakeholders involved with transportation safety; it replaces the Strategic Highway Safety Plan (2014 -2019). The plan guides all Colorado agencies and other stakeholders in taking action on improving transportation safety – specifically in areas of leadership, safety culture, driver behavior, and infrastructure. The plan incorporates a "Zero Deaths" philosophy, and has identified 15 key strategies to target Colorado’s high and critical priority safety issues. Our goal is to reduce fatalities and serious injuries in Colorado by 15% by 2023.
