Executive Summary

Colorado’s (5 year average) fatalities and fatal crash rates have increased in 2015. Both (5 year average) 

serious injuries and the serious injury crash rate have seen little change in 2015. 

In FY 2016, Colorado was notified as being non-compliant with 23 U.S.C. Section 164. CDOT requested 

that 100% of the penalty amount be shifted from the National Highway Preservation Program (NHPP) 

and 100% of those funds be assigned to the Highway Safety Improvement Program (HSIP). The funding 

assigned to the HSIP will be used for eligible activities described in 23 U.S.C. Section 148 to correct 

hazardous locations, reduce identified safety problems, proactively address safety risks, and address 

safety emphasis areas identified in Colorado's Strategic Highway Safety Plan (SHSP).

Colorado uses HSIP resources to incorporate safety improvements across a broad range of maintenance, 

safety and non-infrastructure projects. Innovative methodologies developed and used by CDOT will 

continue to identify more locations, on a statewide scale, with the greatest potential for crash 

reduction. Applications of new Highway Safety Manual concepts and systemic approaches are also 

being integrated into the HSIP program.

The SHSP implementation plan will target goals and devise strategies in each emphasis area to see 

where improvements can made in order to support the vision of moving towards zero deaths. In the 

next fiscal year, CDOT hopes to solicit a greater number of off system (non-state highway) locations with 

high potential for crash reduction with the help of local agencies partners and stakeholders.

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.

Program Structure

Program Administration

How are Highway Safety Improvement Program funds allocated in a State? 

Central

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 solicited from local authorities through the various 

Metropolitan Planning Organizations (MPO's) 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 necessary, are also requested to make project cost adjustments with the 

submitting local authorities’ concurrence.

Briefly describe coordination with internal partners. 

The CDOT HQ Traffic and Safety Engineering (TSE) branch periodically produces a statewide composite 

listing of potential locations for crash reduction is compiled for all highway segments and intersections 

performing at a sub-standard level of service of safety (LOSS) as well as identifying crash patterns that 

are over-represented at those locations. This listing is provided to each CDOT Region where their traffic 

units, roadway design staff and transportation planners can coordinate and select appropriate safety

improvement projects with the goal of reducing roadway fatalities and serious injuries. The Regions use 

the 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 projects. The Region may also choose to 

nominate other safety project locations besides those mentioned on the listing.

Applications for new highway safety improvement projects are sent to TSE branch for evaluation to 

determine HSIP eligibility and level of funding. The TSE branch works with the Office of Financial 

Management & Budget (OFMB) to determine the amount of HSIP funding available for the current fiscal 

year as well as how much is anticipated to be available in future fiscal years for HSIP project planning 

and scheduling. The TSE branch also works with OFMB to obtain status updates on HSIP obligation and 

expenditure amounts for ongoing projects. Approved HSIP projects are incorporated into the Integrated 

Safety Plan in coordination with the CDOT Office of Transportation Safety group and their safety 

programs.

Describe any other aspects of the Highway Safety Improvement Program methodology on which you 

would like to elaborate. 

Over the last year, CDOT Traffic and Safety has participated in peer exchanges covering the Systemic 

Approach and also Data Driven Safety Analysis using the Highway Safety Manual. CDOT is looking 

towards incorporating more of these elements into the HSIP program. CDOT has applied HSIP funding in 

updating all Colorado specific highway segment diagnostic norms and safety performance functions 

(SPF) using the latest available crash data. Over the next year, CDOT plans to update Colorado specific 

intersection diagnostic norms and SPF's using HSIP funding. This will include rural intersection SPF's 

which had not existed prior. These improvements in crash data analysis will help identify new locations 

with potential for crash reduction which will be vital in helping to reduce fatalities and serious injuries 

across the state. HSIP funding has also been applied to before-and-after studies to help assess the 

safety impact and performance of individual safety improvement projects funded by HSIP.

HSIP funding has applications towards the following efforts:

• Crash Data Improvements

• Statewide Safety Summit (Towards Zero Death)

• Workzone Safety Devices and Strategies

• Traffic Incident Management

• New Technology

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

overcome this in the future.

CDOT's Office of Financial Management and Budget (OFMB) does not typically obligate HSIP funding 

until the project has invoices submitted while under construction. The purpose of this is limit the

possibility of having inactive projects. However, this does impact Colorado HSIP obligation rates as this 

tends to result in delayed obligation of funds for HSIP projects. 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.

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

progress on which you would like to elaborate.

The OFMB is working with the HSIP program managers to find ways to manage Section 164 penalty 

funds so that those funds can be obligated immediately. It is anticipated that Section 164 penalty 

funding will continue into future fiscal years in Colorado.

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

Following the trend seen across the country, fatalities have seen a noticeable increase in Colorado in 

2015. Even with increased VMT, fatality rates have also increased. There were no specific areas where 

the increase of fatalities were over-represented. Serious injuries have remained relatively stable in this 

time with the rate continuing to decrease over the last several years.

Application of Special Rules

Present the rate of traffic fatalities and serious injuries per capita for drivers and pedestrians over the 

age of 65.

*Performance measure data is presented using a five-year rolling average.

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)

What significant programmatic changes have occurred since the last reporting period? 

Other-Section 164 Penalty Funds

Briefly describe significant program changes that have occurred since the last reporting period. 

In FY 2016, Colorado was notified as being non-compliant with 23 U.S.C. Section 164. CDOT requested 

that 100% of the penalty amount be shifted from the National Highway Preservation Program (NHPP) 

and 100% of those funds be assigned to the Highway Safety Improvement Program (HSIP). The funding 

assigned to the HSIP will be used for eligible activities described in 23 U.S.C. Section 148 to correct 

hazardous locations, reduce identified safety problems, proactively address safety risks, and address 

safety emphasis areas identified in the State Strategic Highway Safety Plan.

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

which you would like to elaborate. 

The HSIP program will be running a new local agency solicitation in late 2016 to increase safety 

improvements along off system locations across Colorado. A new HSIP procedure manual will be 

released this year to help guide the local agencies through the application and evaluation process. The 

implementation of the SHSP will also aid in this effort, as emphasis area teams will meet and focus on 

future strategies to reduce fatalities and serious injuries for their respective areas.
