Executive	Summary

The Highway Safety Improvement Program (HSIP) is a	core Federal-aid program with the	purpose	to

achieve	a	significant reduction in fatalities and serious injuries on all public roads. Under the	Moving	

Ahead	for Progress in	the 21st Century Act, Congress authorized	approximately $2.4 billion	per year for

States to achieve	this goal through the	implementation of highway safety improvement	projects, which

is	nearly	double	the	amount	that	was	authorized	under	the	previous	legislative	act.	The	States	not	only

met this challenge, but far exceeded it obligating nearly $3.9 billion for over 4,100	highway safety

improvement	projects in	2015.	

These highway safety improvement projects come in all shapes and sizes. Some HSIP	projects are much

bigger in	scope than	others, while other projects include countermeasure installations across multiple

sites. The 2015 HSIP National Summary Report provides an aggregate summary of the type and cost of

projects across all States.	Highlights of the States’ 2015 HSIP implementation efforts are provided below.

•	 A	majority (roughly two-thirds)	of	HSIP projects cost	less than $500,000	each, with 35 percent of

all projects costing less than $100,000.

•	 About 20 percent of HSIP projects would	be considered	high	cost, coming in	at over $1 million	

each. These	projects often include	widening	shoulders, adding	auxiliary lanes, installing	cable

barrier, installing rumble strips, or modifying traffic signals.

•	 Projects associated with a	functional class were	most often categorized as rural major collector

or other urban	principal arterial.

•	 Projects on urban principal arterial interstates had the	highest average	total cost per project of

$3.01	million, whereas projects on rural local roads or streets had the lowest average total cost

per project of $330,000.

•	 There are fewer urban projects than rural projects but the average total cost per project of the	

urban	projects is greater than	the average total cost per project of the rural projects.

•	 About 70 percent of highway safety improvement projects occur on	roads owned	by the State

Highway Agency.

•	 Projects on roads owned by State	Highway Agencies had the	third highest average total cost per

project of approximately $1.1 million, while projects on	roads owned	by County Highway

Agencies cost just over $400,000 on	average.

•	 A	majority (70%) of highway safety improvement projects falls into	the following categories:

roadway, intersection traffic control, intersection geometry, roadside and shoulder	treatments.

•	 Interchange	design,	animal-related, and advanced technology and ITS have the highest	average

cost per project; whereas	roadway	signs	and traffic control, speed management, and work zones

have the lowest average cost per project.

•	 States use	HSIP	funds to address the	predominant infrastructure-related crash types – roadway

departure, intersection, and	pedestrian	crashes.

The number and	cost of HSIP projects has continued	to	increase from 1,684 projects with	a total cost of

$1.61B in 2009	to 4,188	projects with a	total cost of $3.90B in 2015. Over the past seven years, States

obligated	$16.6 billion	for more than	19,000	highway	safety	improvement	projects.

Background

The Highway Safety Improvement Program (HSIP) is a	core Federal-aid program with the objective to

achieve a	significant reduction in traffic fatalities and serious injuries on all public roads through the	

implementation	of	highway	safety	improvement projects.	The HSIP, similar to other Federal-aid

programs, is a federally-funded, state administered program. The FHWA establishes the HSIP

requirements via 23 CFR 924, and the States develop and administer	a program to best	meet	their	

needs.

The HSIP	requires a	data-driven, strategic approach	to	improving highway safety on	all public roads that

focuses on performance. To obligate HSIP	funds, each State shall:

• Develop, implement, and update a State strategic highway safety plan;

• Produce	a	program of projects or strategies	to reduce identified safety problems; and

• Evaluate the SHSP	on a	regularly recurring basis.

States are	also required to submit a report that describes the progress being made to	implement

highway safety improvement projects and	the effectiveness	of those improvements. The HSIP MAP-21	

Reporting Guidance outlines the content and	schedule for the annual HSIP report.	The HSIP report

should include, at a	minimum,	a	discussion of each	State’s:

• Program Structure

• Progress in Implementing the	HSIP	projects

• Progress	in Achieving Safety Performance Targets

• Assessment of the Effectiveness of the Improvements (Program Evaluation)

The HSIP	2015 National Summary Report compiles and	summarizes	aggregate information related to the

States progress in implementing HSIP	projects during the 2015 reporting cycle.	Progress in implementing

HSIP projects is described based on the amount of HSIP funds available and the number and general

listing	of projects obligated as documented in the 2015 HSIP reports.	The HSIP 2015 National Summary

Report is not intended	to	compare states; rather to	illustrate how the states are collectively

implementing the HSIP to	reduce fatalities and	serious injuries on	all public roads across the nation.

A	summary of available funding and	the number and	general listing of projects from prior years is

available	in the HSIP National Summary Baseline Report: 2009 -2012, HSIP 2013 National Summary

Report,	and	HSIP 2014 National Summary Report.

HSIP Funding Approach

Prior to MAP-21, each apportioned program had its own formula	for distribution, and the	total amount

of Federal assistance a State received was the sum of	the amounts it	received for	each program. MAP-21	

instead	provides a	total	apportionment	for	each	State	and	then	divides	that apportionment amount

among individual apportioned programs.

MAP-21	authorizes a	total combined amount ($37.5	billion in FY13 and $37.8	billion in FY14 and FY	15)	

in	contract authority to	fund	five formula programs (including certain	set-asides within the	programs

described	below):

• National Highway Performance Program (NHPP);

• Surface	Transportation Program (STP);

• Highway Safety Improvement Program (HSIP);

• Congestion	Mitigation	and	Air Quality Improvement Program (CMAQ); and

• Metropolitan Planning Program.

Figure	1 illustrates	the	distribution	of	funds	across	programs under MAP-21.

Figure 1: MAP-21	Program Apportionments

HSIP receives 7% of the States apportionment remaining after allocations to CMAQ and Metropolitan

Planning, which amounts to approximately $2.4	billion each year, nearly double	the	amount

apportioned to HSIP	under SAFETEA-LU. The following	sums are set-aside	from the	State's HSIP	

apportionment:	

• Railway-highway crossings -- $220	million;

• A	proportionate share of	funds for	the State's Transportation Alternatives (TA)	program;	and

• 2% for State	Planning and Research (SPR).

In	addition, if	the	High	Risk	Rural	Roads	Special	rule	applies	to a	State,	then in	the	next	fiscal	year	the

State	must obligate an amount at least equal to 200% of its FY	2009	HRRR set-aside for	high risk rural

roads.

The final HSIP	apportionment represents the amount of funding available to States for the advancement

of highway safety improvement projects.

HSIP Projects	Overview

States provide	project specific information for all projects obligated with HSIP	funds during the	reporting

period	in	their annual HSIP reports. The reporting period	is defined	by the State and	can	be calendar

year, state fiscal year or federal fiscal year. For 2015,	the	States obligated	$3.9B	for 4,188 total projects.

These obligations utilized funds apportioned during the 2015 fiscal year	as well as HSIP funds available

from previous years’ apportionments.

As per the HSIP MAP-21	Reporting Guidance, project specific information	includes:

• Improvement	Category and Sub Category (see Appendix A for	complete descriptions)

• Project output (e.g., miles of rumble	strips)

• Project cost (both HSIP cost	and total cost)

• Funding category

• Functional classification

• AADT

• Posted speed limit

• Roadway ownership

• Relationship	to	the State's strategic highway safety plan	(SHSP) (i.e. emphasis area, strategy)

The following sections present various summaries of the nationwide HSIP	project obligations for the	

2015 reporting cycle.	It should be noted that limited	analysis	of	the project information	can	be	done

because not all states have included	all	of	the	above	information	for	each	project in	their	annual	HSIP

reports.	Full use	of the	HSIP online reporting tool and compliance	with the	most recent HSIP	reporting

guidance	will enable	more complete and accurate reporting of national HSIP project data.	In	addition,

HSIP projects	come in all shapes	and sizes. For example, some HSIP projects	may	be much bigger in

scope than others, countermeasure installations	across	multiple sites, or non-infrastructure	projects	(i.e.	

transportation safety planning, data improvements). Nonetheless, the	summaries in the	following	

sections	provide a broad scale analysis	of HSIP spending in 2015 by project cost, functional classification	

and ownership, improvement categories and subcategories, and SHSP	emphasis areas.

Project Cost

The cost per HSIP project in 2015 ranged widely. Some projects were small in scope and cost, such as

replacing signs on a particular	route. Others were higher	cost	projects, such as widening a highway or	

reconfiguring an intersection. Figure	2 shows	the breakdown by project cost, grouped into general

categories	with breakpoints	at $100,000, $500,000, and $1,000,000.

Figure 2:	Number of Projects by Project Cost

Roughly two-thirds of	the projects had costs less than $500K. A small	percentage	(12 percent) fell into	

the $500K	- $1M category. The	remaining 22 percent were high	cost projects totaling $1M or more. The

top five sub categories selected for	these high	cost projects are:

• Widen	shoulder – paved	or other (139 projects ranging	from 0.3 to 21.4 miles treated)

• Auxiliary lanes – add left-turn lane (46 projects)

• Barrier – cable (30 project ranging from 0.1 to 29 miles	treated)

• Rumble strips – edge	or shoulder (30 projects	ranging from 1	to 1300	miles treated)

• Modify traffic signal – modernization/replacement (27 projects)

In	2013 and 2014,	the	breakdowns	were similar. About two-thirds of the projects had costs less than

$500K, about 13 percent fell into	the $500K - $1M category, and the	remaining 20	percent were	more	

than $1M.

Functional Class and	Ownership

Figure	3 through Figure	7 illustrate the distribution of	projects by the types of	roads on which they were

conducted. Figure	3 shows	number of projects by functional class, following the HPMS classification	

scheme; Figure	4 shows	average total cost of projects	by functional class; Figure	5 shows	the number

and average	total cost of projects	by	urban/rural designation; Figure	6 shows	projects	by the agency

who owns the road;	and Figure	7 shows	average total cost of projects	by the agency who owns	the road.

If	the	functional	class	or	road	ownership	was	not	indicated,	the	project is	counted	under	the	“unknown”

category. Examples of classifications in the “other”	category	include multiple functional classes, state or

citywide implementation, or non-infrastructure	projects.	

Figure 3.	Number of Projects by Functional Class

As in	2014, most projects were categorized	as “Unknown” indicating that the State did not associate a	

functional class for a	particular project. Projects that	were associated with a	functional class were	most

often	categorized	as “Rural Major Collector” or “Urban Principal Arterial – Other”.	There were 419

projects categorized	as “Other” and of those, roughly 250 were categorized as multiple classes or

systemic. Roughly another 30 projects were categorized as “n/a” due to	the fact that they were noninfrastructure	projects.

Figure 4.	Average Total Cost of Projects by Functional Class

Figure	4 shows	the average total cost of projects	by functional class. It is	important to note that not

every project had an associated cost so the	average	is based on the	number of projects which had cost

information available. Projects categorized as “Urban Principal Arterial – Interstate”	had	the	highest

average total cost	per	project	of	$3.01 million (compared to $2.73M in 2014) and projects categorized as

“Rural Local Road or Street”	had the lowest average total cost	per	project	of $330,000 (compared to

$220,000 in	2014).

Figure 6.	Number of Projects by Road Ownership

As in	2014, States implement	most projects on	roads owned	by a “State Highway	Agency”	or “Unknown”	

(indicating	that	the	State	did	not indicate road ownership for	a particular	project).	There were 110

projects categorized	as “Other”	and of those, roughly	90	were	categorized in state-defined	ownership	

categories.	No projects were categorized for the following ownerships:

• State	Park, Forest, or Reservation Agency

• Private	(Other than Railroad)

• Railroad

• State	Toll Authority

• Local Toll Authority

• Other Public Instrumentality

Figure	7 shows	the average total cost of projects	by road ownership. It is	important to note that not

every project had an associated cost so the	average	is based on the	number of projects which had cost

information	available.	Projects categorized as “Other State	Agency” had the	highest average	total cost	

per project of $9 million and projects categorized as “Local Park, Forest, or Reservation Agency”	had the

lowest	average	total	cost per project of $81,000.

Improvement Categories and Subcategories

Under the HSIP MAP-21	reporting guidance,	each project should be assigned	a general improvement

category	and a subcategory	under that general category. While a single project may consist of multiple

project types, FHWA directs States to assign each project to only one	category. The	category chosen

should align with the primary purpose of the project. Figure	8 and Figure	9 show the distribution of the

number of projects by general improvement category. Figure	10 and Figure	11 combined show the

distribution	of the total cost of projects by general improvement category. Projects categorized as

“Unknown”	indicate that there was no general improvement category	assigned by	the State. Figure	12

through Figure	16 show the breakdown	of the number of projects by subcategory for five improvement

categories:	Intersection	geometry,	Intersection	traffic	control,	Pedestrians	and	bicyclists,	Roadway,	and

Non-infrastructure.	More detailed tables with the cost spent in each subcategory	are	available	in

Appendix B. For ease	of reporting, similar subcategories were	grouped together. For example, in Figure	

12 below, “Auxiliary lanes – other” combines adding acceleration lanes, adding auxiliary through lanes,

adding two way left turn lanes,	and	several	other related subcategories.

Figure 8.	Number of Projects by Improvement Category (Top 11)

Figure	8 shows	the number of projects by improvement category (top 11) as classified in the HSIP MAP21 Reporting Guidance. Based	on	the project information reported by the States, the top five

improvement categories are	roadway, intersection traffic control, intersection geometry, roadside, and

shoulder treatments. In 2013 and 2014,	the	top	five	improvement	categories	were	the	same	and	the

numbers of projects classified	in	each	category were similar with	the	exception	of	the	roadway	category.

In	2015,	there	were	approximately	475	additional	projects	classified in	the	roadway	category.	The

ranking of	the remaining project	categories was similar	in all three years.

Figure 9.	Number of Projects by Improvement Category (Bottom 11)

Figure	9 shows	the number of projects by improvement category (bottom 11)	as classified in the HSIP

MAP-21 Reporting Guidance. In	2014,	the	number	and	ranking	of	projects	classified in	each	category	for

the bottom 11 were similar.

Figure 10.	Average Total Cost of Projects by Improvement Category (top	11)

Figure	10 shows	the average total cost of projects	by improvement category (top 11).	Again, it is

important	to	note	that	not	every	project	had	an	associated	cost	so	the	average is	based	on	the	number

of projects with	cost available. Compared	to	2014, the following categories had	notable differences in

average	project costs. Note	that the	“Multiple” category indicates that a	State	selected more	than one	

improvement	category.	For	example,	the	project	could include changes to lighting, signs, pavement	

markings, intersection geometry, and number of lanes.

•	 Lighting	– moved from	the top 11 in 2014 to the bottom	11 in 2015 (decreased	from $1.2M in	

2014	to $527K	in 2015)

•	 Multiple – moved from	the top 11 in 2014	to the	bottom 11	in 2015	(decreased	from $1.2M in	

2014	to $190K	in 2015)

•	 Animal-related – remained in the top 11 for	2015 (increased	from	$1.6M in	2014	to	$7.5M in

2015)

Figure 12: Number of Intersection Geometry Projects by Subcategory

The Intersection geometry category was selected for further evaluation because in	2015	(as in	previous

years) it ranked in the top five in	terms	of	number of projects categorized	and	ranked in	the bottom 11	

in	terms	of	average	cost	per	project. FHWA has also identified intersections as one	of three	focus areas

for	the Focused Approach to Safety effort.

For the	Intersection geometry category, most projects are sub categorized as	“Intersection	geometrics –

other/unknown”	(45	percent; 254	of 559 projects), “Auxiliary lanes – add left-turn lane” (28	percent;

155	of 559 projects),	and	“Auxiliary	lanes – other” (13	percent; 72	of 559	projects).	Examples of projects

in	the	“Intersection	geometrics – other/unknown”	subcategory	include modify intersection corner

radius and general intersection safety improvement projects. The “Intersection geometrics –

other/unknown” subcategory is predominately used	without any project description, therefore, no	

other information	is available for these projects.

The Intersection	traffic control category was selected	for further evaluation	because in	2015 (as in	

previous years) it ranked	in	the top	five in	terms of number of projects categorized. FHWA has also

identified	intersections	as	one	of	three	focus	areas	for	the	Focused	Approach	to	Safety	effort.	

For the Intersection traffic control category, most projects	are subcategorized as	“Intersection	traffic

control – other/unknown”	(38	percent; 231 of 615 projects) and “Modify traffic signal” (29	percent; 179	

of 615 projects). Examples of projects in	the “Intersection	traffic control – other/unknown” category

include	projects	described	as	signal	and	stop	controlled	systemic	improvements and general intersection

traffic control improvement	projects. The “Intersection traffic control – other/unknown” subcategory is	

predominately used	without any project description, therefore, no	other information	is available for

these projects. Examples of projects in the “Modify traffic signal” category include

modernization/replacement of traffic signal and adding flashing yellow arrow signals.

Figure 14:	Number of Pedestrian and Bicyclist Projects by Subcategory

The Pedestrian and bicycle category	was	selected for further evaluation because infrastructure

improvements in	this	category	are	of	significant	interest to various stakeholders.	FHWA has also

identified pedestrians and	bicyclists as one	of three	focus areas	under the Focused Approach to Safety

effort.

For the Pedestrians and bicyclists category, most projects are	subcategorized as	“Miscellaneous

pedestrian and bicyclist improvements” (40	percent; 49	of 122 projects) and	“Install	or	modify

pedestrian	signal”	(25	percent; 31	of 122 projects). Many of the projects in	the	“Miscellaneous

pedestrian	and bicyclist improvements” subcategory	do	not have any project description, therefore, no	

other information	is available for these projects.

ranked as the number	one category in terms of	number	of	projects categorized. FHWA has also

identified	roadway	departure	as	one	of	three	focus	areas	for	the	Focused	Approach	to	Safety	effort.	

For the Roadway category, most projects were subcategorized as	“Roadway	– other/unknown” (46	

percent; 553	of 1195	projects) and “Rumble strips”	(36	percent; 427	of 1195 projects). Examples	of

projects in	the	“Roadway – other/unknown”	subcategory were projects such as “restripe to revise

separation between opposing lanes	and/or shoulder widths”.

SHSP Emphasis	Areas

Based	on	a review of State SHSPs, FHWA	identified	the eight SHSP	emphasis areas common across	most

States. These emphasis areas are used in the HSIP online reporting tool for	categorizing HSIP projects.	

Figure 17 presents the number of HSIP projects categorized	by SHSP	emphasis area. For consistency and

national reporting purposes, state-defined	SHSP	emphasis areas were assigned to these emphasis areas,

where possible. Please note that States sometimes categorize a single project	by several SHSP	Emphasis

Areas. Therefore, for the purpose of Figure 17,	a	single	project	may	be	counted	more	than	once.	For

example, the	State	recently completed an intersection improvement project that enhanced safety for

pedestrians. This project could	be categorized as “Intersections” as well “Pedestrians” and is therefore	

counted once in each category.

About 42	percent of the projects were categorized	as “Roadway Departure” (33 percent	in 2014),	31	

percent were categorized as “Intersections” (27 percent	in 2014),	14	percent categorized as	

“Unknown/Other” (26 percent	in 2014.	Examples of other categories used by the States include:

“Improve	driver	decisions	about	rights-of-way and turning”, “Spot safety improvements”, and “Curbing

aggressing driving”.

2013-2015 Comparison

Most states prepared their 2013 through 2015 HSIP reports in accordance with the MAP-21	HSIP	

Reporting Guidance; therefore FHWA	can	make a direct comparison	of information	related	to	the 2013

through 2015 highway safety improvement projects. As can	be seen	in	Table 3 below, the total number

of projects and	cost of projects did	not change much	from 2013 to	2014 but in	2015, there were roughly

900	more	projects reported.	However, the breakdown	in	project costs for various breakpoints was

similar across years.

Summary

The HSIP	is a	strategic program that uses data	and analysis to target safety resources. This HSIP 2015

National Summary Report shows that in	2015,	States	directed	HSIP	funds	to	address	the	predominant

infrastructure -related crash types - roadway departure, intersection and pedestrian crashes,	similar	to

previous years. While the basic characteristics (rural and urban, improvement	categories, and SHSP

emphasis areas) of HSIP spending remains fairly consistent from year to year, the number and	cost of

HSIP projects has continued	to	increase over the seven-year period from 1,684 projects with a total cost	

of $1.61B	in	2009 to	4,188	projects with a	total cost of $3.90B in 2015.
