Executive Summary

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. 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 from a 1995 base year level. 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 nonsafety-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 Hazard Elimination 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 
2013 Colorado Highway Safety Improvement Program

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 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 high hazard locations 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.

A location does not need to be on a listing of high harzard locations to be considered for HSIP 

funding. Any local agency can initiate a request through their Regional office to see if a safety 

improvement for a public road can qualify for HSIP funding. The same methodology is applied 

to these potential safety improvements.

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 alcohol-related 

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...”

2012 = 56 FAT, 242 INJ, 118 CAPITA

2011 = 47 FAT, 200 INJ, 112 CAPITA

2010 = 51 FAT, 178 INJ, 109 CAPITA

2009 = 58 FAT, 191 INJ, 106 CAPITA

2008 = 68 FAT, 187 INJ, 104 CAPITA

2007 = 55 FAT, 198 INJ, 101 CAPITA

2006 = 47 FAT, 215 INJ, 100 CAPITA

2005 = 52 FAT, 176 INJ, 97 CAPITA

2004 = 57 FAT, 220 INJ, 99 CAPITA

2009 Rate Example Equation:

2009 Fatality Rate (five year rolling average) = ((2009 FAT/2009 CAPITA)+(2008 FAT/2008 

CAPITA)+(2007 FAT/2007 CAPITA)+(2006 FAT/2006 CAPITA)+(2005 FAT/2005 CAPITA))/5

2009 Serious Injury Rate (five year rolling average) = ((2009 INJ/2009 CAPITA)+(2008 INJ/2008 

CAPITA)+(2007 INJ/2007 CAPITA)+(2006 INJ/2006 CAPITA)+(2005 INJ/2005 CAPITA))/5

2009 Fatality and Serious Injury Rate (five year rolling average) = 2009 Fatality Rate (five year 

rolling average)+2009 Serious Injury Rate (five year rolling average)

Assumptions:

For 2012 Capita, use 2011 Capita (from Attachment 2 in Section 142: Older Drivers and 

Pedestrians Special Rule Interim Guidance)

For 2004 Capita, use 2005 Capita (from Attachment 2 in Section 142: Older Drivers and

Describe any other aspects of the overall Highway Safety Improvement Program effectiveness on 

which you would like to elaborate. 

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.

Glossary

5 year rolling average means the average of five individual, consecutive annual points of data (e.g. 

annual fatality rate).

Emphasis area means a highway safety priority in a State’s SHSP, identified through a data-driven, 

collaborative process. 

Highway safety improvement project means strategies, activities and projects on a public road that are 

consistent with a State strategic highway safety plan and corrects or improves a hazardous road location 

or feature or addresses a highway safety problem. 

HMVMT means hundred million vehicle miles traveled.

Non-infrastructure projects are projects that do not result in construction. Examples of noninfrastructure projects include road safety audits, transportation safety planning activities, 

improvements in the collection and analysis of data, education and outreach, and enforcement 

activities.

Older driver special rule applies if traffic fatalities and serious injuries per capita for drivers and 

pedestrians over the age of 65 in a State increases during the most recent 2-year period for which data 

are available, as defined in the Older Driver and Pedestrian Special Rule Interim Guidance dated 

February 13, 2013. 

Performance measure means indicators that enable decision-makers and other stakeholders to monitor 

changes in system condition and performance against established visions, goals, and objectives.

Programmed funds mean those funds that have been programmed in the Statewide Transportation 

Improvement Program (STIP) to be expended on highway safety improvement projects.

Roadway Functional Classification means the process by which streets and highways are grouped into 

classes, or systems, according to the character of service they are intended to provide.

Strategic Highway Safety Plan (SHSP) means a comprehensive, multi-disciplinary plan, based on safety 

data developed by a State Department of Transportation in accordance with 23 U.S.C. 148. 

Systemic safety improvement means an improvement that is widely implemented based on high risk 

roadway features that are correlated with specific severe crash types. 

Transfer means, in accordance with provisions of 23 U.S.C. 126, a State may transfer from an 

apportionment under section 104(b) not to exceed 50 percent of the amount apportioned for the fiscal 

year to any other apportionment of the State under that section.
