MUTCD Proposed Amendments

The much-anticipated proposed 11th edition of the MUTCD is now available for public comment! The public docket is open for comment submissions through May 14, 2021. However, CDOT has created Google forms to compile comments on the behalf of the State of Colorado to address the 647 proposed amendments to the MUTCD through April 30, 2021.

We have divided the proposed amendments into multiple sections to better facilitate your time and expertise. Please provide feedback to all proposed amendments that you feel comfortable with and be sure to provide comments to explain your reasoning for all "Partially Agree" and "No" responses.

About Us

Our Mission

Strategically reduce traffic crashes and resulting deaths, injuries, and property damage; and to improve the flow of traffic through application of traffic engineering principles.

Our Vision

Become the state agency sought-out leader for applying traffic engineering principles to improve traffic safety and maximize the operations of the highway system, and the foremost resource of crash data, analysis, and engineering strategies - and mitigation for improving highway safety and operational efficiency.

Our Values

We work, think, and live safety! We value our employees! We earn Colorado's trust by satisfying our customers! We are committed to quality! We respect each other!

Our branch exists to support CDOT's five regions, our headquarters divisions, and the greater transportation community in Colorado and the nation to achieve the safest and best operating transportation system possible for our customers. Our diverse team of problem solvers - made up of engineers, technicians, data professionals and support staff - provide services and consultation to our regions in many traffic engineering, operations, and safety areas.

We assist CDOT, other state agencies and local agencies in making data-driven, prioritized decisions by collecting and connecting vast amounts of data, analyzing it, providing safety performance mapping and analysis, and sharing it internally and statewide for use in CDOT strategizing and program and project development.

We facilitate statewide discussion and establishment of policies, procedures, standards, specifications, guidelines, best practices, strategies, and products that improve the safety and reliability of our network.

We administer funded programs with the regions to deliver projects and strategies that improve the safety and reduce bottlenecks and other cause of congestion. We further advise all CDOT projects on strategies every project can employ opportunistically to improve safety and operations.

Our team holds a vast amount of experience and expertise in the above areas, and we also have a vast network of experts we work with to learn and deploy the best practices possible - from Federal Highway Adminstration's (FHWA's) Division, Resource Center, and HQ to the American Association of State Highway Transportation Officials (AASHTO) network of our nation's traffic engineering and operations professionals, to our local agencies, to the consulting and contracting associations and members, and with several others.

In summary, through data analysis, planning, and engineering, we work to prevent crashes and congestion from occurring and where they do, we use our knowledge and expertise, and the many strategies known to us to solve those issues for the BEST and SAFEST trip our customers expect and deserve.

Our Services

Traffic Data Management Services

The importance of accurate data collection and reporting cannot be overemphasized. Many individuals and agencies, both from the public and private sector, use and rely on information gathering on crash reports. That information leads to improved roadway safety at local, state, and federal levels and save lives. Our unit is administers the 405 Traffic Records, Crash Data, Fatality Analysis and Reporting System (FARS), and the Statewide Traffic Records Advisory Committee (STRAC).

Traffic Safety Programs & Analysis Services

Our unit is responsible for supporting the ongoing statewide efforts to improve traffic safety along all public roadways in Colorado through strategic data-driven approaches. Highway Safety Manual concepts are frequently applied by the group through the use of predictive crash models and crash modification factors. We administer two major programs - Highway Safety Improvement Program (HSIP) and FASTER Safety Mitigation (FSM) Program - that are devoted to improving safety through the reduction of crashes, most notably those that cause serious injuries and fatalities.

Traffic Control, Standards & Specification Services

Our unit provides highway, work zone safety, and traffic operations-related input for transportation planning and project development; and traffic engineering support. We develop and maintain traffic engineering specifications, standards, and related publications; and the centralized library of CDOT sign layout templates. We administer statewide policies on guide signing practices and procedures, as well as those governing pavement marking practices; and the CDOT Flagger Program. We evaluated an approved traffic control devices for the CDOT Approved Products List.
