Executive Summary

The general trend in fatal crash reduction experienced on Colorado roadways has continued to remain 

stable in the most recent reporting period. Colorado’s Strategic Highway Safety Plan (SHSP) emphasizes 

the goal of crash reduction and includes, among other performance measures, reducing fatal and injury 

crash rates. Colorado has continued to progress in meeting these goals by effectively utilizing HSIP 

resources to incorporate safety improvements across a broad range of maintenance, safety and even 

non-safety-specific projects. Innovative methodologies have been developed and used by CDOT to 

identify locations, on a statewide scale, with the greatest potential for crash reduction. Crash data 

processing has improved considerably over the last few years. The increase in completeness, accuracy 

and timeliness has significantly improved crash data analysis and network screening. In combination 

with HSIP funding, these procedures have been applied to the selection of highly cost-effective safety 

improvement projects constructed under the Federal Highway Safety Improvement Program. An 

updated SHSP is anticipated to be implemented within the next fiscal year. This new SHSP will provide a 

detailed analysis of safety performance measures and will focus on additional emphasis areas in order to 

provide guidance on how to reduce severe crashes across the state.

Introduction

The Highway Safety Improvement Program (HSIP) is a core Federal-aid program 

with the purpose of achieving a significant reduction in fatalities and serious 

injuries on all public roads. As per 23 U.S.C. 148(h) and 23 CFR 924.15, States are 

required to report annually on the progress being made to advance HSIP 

implementation and evaluation efforts. The format of this report is consistent 

with the HSIP MAP-21 Reporting Guidance dated February 13, 2013 and consists 

of four sections: program structure, progress in implementing HSIP projects, 

progress in achieving safety performance targets, and assessment of the 

effectiveness of the improvements.

Describe how local roads are addressed as part of Highway Safety Improvement Program. 

Under this program all public roadways are eligible for participation. Submittals for projects not located 

on the State Highway system are also solicited from local authorities through the various MPOs and the 

Special Highway Committee of the Colorado Counties, Inc. and the Colorado Municipal League. These 

candidate proposals for safety improvement projects are submitted for locations identified using the 

locals’ own high hazard locations identification system. As with the Region applications, all submittals 

will be required to meet the minimum criteria. Copies of project applications received in the Safety and 

Traffic Engineering Office from locals are submitted to the Region offices for comments, evaluation and 

approval. The Region offices are specifically requested to verify project cost estimates, and when 
2014 Colorado Highway Safety Improvement Program

necessary, are also requested to make project cost adjustments with the submitting local authorities’ 

concurrence.

Briefly describe coordination with internal partners. 

A statewide composite listing of potential locations for accident reduction is compiled for all highway 

segments and intersections performing at a sub-standard level of service of safety (LOSS) as well as 

identifying accident patterns that are overrepresented at those locations. This listing is then stratified 

by the Region and provided to the appropriate CDOT Regions and Local Agencies for review. The initial 

candidate listing of high hazard locations is reviewed by each Regional traffic engineering unit. The 

Regions use the high hazard listing along with other information such as their own operational reviews, 

input from citizens, staff and city/county personnel as well as other ongoing or scheduled construction 

activities in order to determine the most feasible and beneficial candidate safety project submittals. The 

Region may also choose to nominate other safety project locations besides those mentioned on the 

listing. Any regional nominations not on the list will still need to meet the criteria discussed above.

Discuss impediments to obligating Highway Safety Improvement Program funds and plans to 

overcome this in the future. 

There are longer than expected start up times for safety improvement projects, especially those run by 

local agencies. Special attention will now be given to construction scheduling and priority for fund 

programming will be given to projects that can deliver on a timely basis. The plan includes identifying 

projects in advance for future fiscal years and funding projects in phases in order to obligate funds in the 

year that they are being spent.

Describe any other aspects of the general Highway Safety Improvement Program implementation 

progress on which you would like to elaborate.

A revised general budget process at CDOT will be implemented which will allow obligation of HSIP 

funding to be processed more efficiently.

Describe any other aspects of the general highway safety trends on which you would like to elaborate. 

The general trend in fatal crash reduction experienced on Colorado roadways has continued in the most 

recent reporting period. In recent years the numbers of fatalities from crashes has fallen from 743 in 

2003 to less than 500 per year since 2009. This positive outcome can be, in part, attributed to the 

FHWA’s focus on improving transportation safety and their support and promotion of this goal through 

the HSIP funding. Results of a recent study by the National Cooperative Highway Research Program 

confirm the benefits of FHWA’s safety funding for Colorado - “...The National Cooperative Highway 

Research Program (NCHRP) Project 20-24(37C) compared Colorado’s safety performance results to other 

states in the US from the period 2000-2002 with those in 2005-2007. This draft report shows how 

Colorado has emerged as a leader in roadway safety: • 22 percent decrease in total fatalities • 31 

percent decrease in fatalities per 100 million VMT • 35 percent decrease in speeding-related fatalities • 

30 percent decrease in young driver involvement in fatal crashes • 20 percent decrease in alcoholrelated fatalities (driver blood-alcohol content greater than 0.08) • 35 percent decrease in unrestrained 

passenger fatalities, all seat positions • 22 percent decrease in pedestrian fatalities...”

HSIP funding has helped Colorado see a major decreasing trend in all crash types over the last ten years, 

not just serious injuries and fatalities. With the help of sustained funding and a renewed focus provided 

by an updated SHSP, it is the goal of CDOT to facilitate the continuation of these downward trends in 

Colorado.
