National
Review of the Highway
Safety Improvement Program
by Kenneth
Epstein, Gary Corino, and Donald Neumann
Safety
is a critical part of the Federal Highway Administrations (FHWA)
mission, and so, FHWA has established a strategic goal to continually
improve highway safety.
The
agency is committed to reducing highway-related fatalities and serious
injuries by 20 percent by the year 2008. An effective Highway Safety
Improvement Program (HSIP) is a major component for improving highway
safety through the implementation of improvements at locations with
known and potential crash problems.
Each
state is required to develop and implement, on a continuing basis,
a highway safety improvement program that has the overall objectives
of reducing the number and severity of crashes and decreasing the
potential for crashes on all highways. HSIP requirements have been
established in the Code of Federal Regulations, Title 23, Part
924 (23 CFR 924), and include components for planning, implementation,
and evaluation of safety programs and projects. These components consist
of processes developed by the states and approved by FHWA.
Between
February and April 2001, a national review was conducted of highway
safety improvement programs in six states: Connecticut, Delaware,
Florida, Iowa, Ohio, and Oregon. The primary purpose of this review
was to document the best, unique practices of each state. These states
were selected on the basis of their size, their outstanding HSIPs,
and their location, providing a geographical balance. This review
was conducted by a team from FHWA that included representatives of
the Safety Core Business Unit and the Corporate Management Service
Business Unit from FHWA headquarters and the FHWA division offices
in the reviewed states.
The
review findings are based on interviews and observations. Interviews
were conducted with senior managers and safety specialists from the
FHWA divisions and state highway agencies responsible for the HSIP.
The interviews focused primarily on the processes being used to plan,
implement, and evaluate the HSIP in that state. People in all of the
states were very eager to demonstrate various innovative and effective
safety programs, processes, activities, and technologies.
Several
safety programs fall under the umbrella of the HSIP. The most notable
of these are the Highway-Rail Grade Crossings Program and Hazard Elimination
Program. These programs were established by the Highway Safety Act
of 1973 to reduce the number and severity of highway-related crashes,
and the requirements of the Highway-Rail Grade Crossings and Hazard
Elimination programs are defined in sections 130 and 152, respectively,
of Title 23, United States Code. The Intermodal Surface Transportation
Efficiency Act of 1991 (ISTEA) incorporated these highway safety programs
into the Surface Transportation Program (STP). Ten percent of the
STP funds are set aside for carrying out sections 130 and 152.
The
Highway-Rail Grade Crossings Program is intended to reduce the number
and severity of train collisions with vehicles and pedestrians. All
public highway-rail crossing safety improvements are eligible for
federal funding. Typical projects include the improvement of the crossing
surface and the installation of lights, gates, signs, and markings.
The
Hazard Elimination Program is intended to make the hazardous locations,
sections, and elements on any public road safer. Typical projects
include intersection improvements; pavement and shoulder widening;
guardrail and barrier improvements; breakaway utility poles and sign
supports; pavement grooving and skid-resistant overlays; shoulder
rumble strips; minor structural replacements or modifications; and
signing and pavement markings.
Findings
The
review team found numerous noteworthy activities related to the HSIP
and safety in general, and it was apparent that there is more than
one means for carrying out a highway safety improvement program. Each
state has tailored its program to its unique needs. Effective safety
programs must take into account existing strengths and weaknesses.
The
team used the following definition from the Chevron Corp. to identify
a best practice: A best practice is any practice, knowledge,
know-how, or experience that has proven to be valuable or effective
in one organization and that may have applicability to other organizations.
Common
Elements
Although
each states safety program is unique, there are common elements
that contribute to program effectiveness. These elements are:
- The
establishment of safety as a major goal of the agency and the commitment
of the highest officials. In several of the states visited,
the governor played an active role in promoting safety. In one state,
the review team met with the new state secretary of transportation,
who reiterated the commitment that he shares with the governor to
improve safety.
- A
good multidisciplinary safety management process with a strong component
for roadway safety. ISTEA required the states to implement a
highway safety management system, which is a systematic process
to reduce the number and severity of traffic crashes by ensuring
that all opportunities to improve highway safety are identified;
considered; implemented as appropriate; and evaluated in all phases
of highway planning, design, construction, maintenance, and operation
and by providing information for selecting and implementing effective
highway safety strategies and projects.
The National Highway System Designation Act of 1995 made the safety
management system and most other mandated management systems optional.
However, many states have retained their safety management systems,
and the systems observed in the states visited were highly effective.
Having a good system provides a focus on safety and enables the
various disciplines to work together to comprehensively address
highway safety problems. Iowa, in particular, has an excellent system.
- Emphasis
on safety in all projects. Although much of the emphasis has
been on remedial efforts, highway safety enhancements have been
implemented in conjunction with new or with other roadway improvement
projects — not just hazard elimination or highway-rail crossing
projects. For example, Oregon emphasizes safety on preservation
projects by providing additional funding to implement safety enhancements.
Under the 1998 Transportation Equity Act for the 21st Century (TEA-21),
safety must be incorporated as part of the state and metropolitan
transportation planning processes. States with good safety management
processes routinely operate in this manner.
- A
designated safety division or a safety engineer/coordinator within
the state DOT. This office or coordinator provides a focal point
for safety and the coordination necessary for an effective safety
program.
- A
designated safety section or safety engineer/coordinator in each
regional office of the state DOT. For the larger states with
regional structures, the office or coordinator in each regional
office further ensures that safety is adequately addressed in all
regional activities from planning through maintenance.
- Community-based
traffic safety programs. Such programs help to elevate the importance
of safety at the community level and provide buy in
by local units of government and the public. These programs ensure
that safety is addressed on the most dangerous parts of the highway
system —local streets and minor collectors.
- Efforts
to assist localities. Many local agencies do not have staff
solely dedicated to highway safety and, therefore, may not have
the expertise to address their highway safety problems and needs.
The states have established programs to address this need. They
include Connecticuts Accident Reduction Program, Iowas
Traffic Engineering Assistance Program, The Roadway Analysis Program
for Fatal and Injury Countermeasures in Ohio, and Oregons
Safety Corridors Program.
- Use
of current technologies.
These technologies, such as Geographic Information Systems (GIS),
photo logging, and web-based systems, help to provide more timely
and accurate information, especially in the areas of data collection
and analysis. GIS is a particularly effective tool and is being
used extensively by some states, including Oregon.
- A
Traffic Records Coordinating Committee. This committee helps
to ensure the timeliness, accuracy, and linkage of data and to avoid
a duplication of effort. It brings together key players in the safety
field, including people who provide engineering, enforcement, and
emergency medical services.

Red-light-running
is a very significant safety problem. |
HSIP
Best Practices
The
following best practices are related specifically to the HSIP:
- Systematic
and well-documented processes.
- Timely
and accurate crash data.
This is critical for determining where efforts should be focused.
Considerable efforts are being made to reduce the period of time
— often six months or more — between when a crash occurs
and when the data are available for use in an automated system and
to more accurately record the crash location. Delaware has been
able to reduce this time to 30 to 60 days.
- Selection
of hazardous locations for corrective action. While there were
a number of variations of the factors used to select the hazardous
locations, the most common factors are crash frequency, rate, and
severity.
Best
Practices for Highway-Rail Grade Crossings
For
programs related to highway-rail grade crossings, the following were
among the best practices observed:
- Efforts
to implement projects more quickly.
- Incentives
to close crossings. Ohio has had significant success in doing
this.
- Public
information campaigns. These campaigns, including Operation
Lifesaver, are designed to enhance public awareness about the potential
dangers at highway-rail grade crossings, thereby reducing collisions
at these crossings.
Best
Practices in Connecticut
In Connecticut,
engineering studies are given major emphasis. A field investigation
is made of all sites being considered for remedial treatment. There
is also coordination with local agencies.
The
Connecticut Department of Transportation (ConnDOT) has established
a financial management process that helps to expedite the implementation
of projects. The staff people responsible for the implementation of
roadway, bridge, and safety projects are assigned to the Bureau of
Engineering and Operations and have backgrounds in both engineering
and finance.
ConnDOTs
photo logging system is a high-quality system that is easy to use.
All data is linked to one referencing system. The system produces
a variety of engineering-related data and reports. It is used extensively
by ConnDOT, other state agencies, and universities.
Best
Practices in Delaware
Safety
is the highest priority of the Delaware Department of Transportation
(DelDOT), and the Delaware Secretary of Transportation is a champion
for safety.
Delawares
HSIP consists of good, systematic, and timely processes that are closely
followed. These processes are institutionalized and stable, which
helps to expedite project development. Throughout the process to construction,
they emphasize consensus-building, both internally and externally.
DelDOT
makes a major effort to involve the public. Its use of large, high-quality
photographs helps to ensure an understanding the improvement.
An
intranet project tracking system for safety projects has been developed
and is available to the entire DOT. This system is up-to-date and
includes project descriptions, pictures, benefits/costs, the bases
for projects, project assignments, delivery dates, and the status
of each project.
Relatively
low-cost improvements — such as signing, traffic signal modifications,
and striping — that are identified from engineering studies are
implemented expeditiously. This builds public confidence in the DOTs
ability to react quickly in these types of situations.
Decisions
about all major aspects of project coordination, including the project
development process and the determination of the level of public involvement,
are made by a committee of representatives of all of the divisions
within DOT.

high accident locations and developing improvements -
Making
Delaware's Highways Safer
Best
Practices in Florida
Safety
is the Florida Department of Transportations (FDOT) highest
strategic goal.
Floridas
Safety Management System (SMS) has an active steering committee, which
holds quarterly meetings throughout the state. This is a good way
to get more agencies involved. The state also has a full-time SMS
coordinator.
|
Guardrails and proper, highly visible road markings are important
aspects of a hazard elimination program. |
Floridas
Community Traffic Safety Teams (CTSTs) are highly successful in implementing
safety improvements. Through the CTSTs, Florida gains several benefits,
including considerable local input in selecting projects and countermeasures,
faster implementation of projects, and the frequent use of informal
agreements to meet the needs of the community.
The
strength of the CTSTs lies in the talents of the individual volunteers
and the synergism of the team. These teams include representatives
from education, engineering, enforcement, and emergency services,
as well as private and other interested groups. FDOTs role is
to provide leadership and direction to the teams, provide resources
and materials, and implement innovative and successful programs. The
number of CTSTs has increased from nine in 1993 to the current level
of 51.
Florida
is divided into districts and each district office includes a safety
engineer, a law enforcement liaison, and CTST coordinators.
All Florida
Highway Patrol vehicles are to be equipped with computerized electronic
data entry systems. Approximately 10 percent of local police agencies
also have this capability. This results in immediate electronic data
entry for about 40 percent to 45 percent of all crash data.
Best
Practices in Iowa
The
close working relationship shared by the Iowa Department of Transportation
(Iowa DOT), the Governors Traffic Safety Bureau, and Iowa State
Universitys Center for Transportation Research and Education
(CTRE) contributes significantly to the advancement of Iowas
safety initiatives.
Iowas
multidisciplinary Safety Management System Coordinating Committee
opens communication channels that enable issues to be addressed better
than if they were addressed by individual agencies. Iowa also has
a full-time SMS coordinator. Through this multidisciplinary approach,
Iowa is able to identify issues, comprehensively test and evaluate
strategies, and ultimately apply tangible solutions to produce the
best return for available resources.
Iowa
modified the American Association of State Highway and Transportation
Officials Strategic Highway Safety Plan to create a state Strategic
Highway Safety Plan that meets Iowas needs.
In
partnership with FHWA, Iowa participated in the development of the
National Model for the Statewide Application of Data Collection and
Management Technology to Improve Highway Safety. This has enabled
Iowa to make maximum use of current technologies. The use of the Traffic
and Criminal Software has resulted in more timely and accurate data,
greater police officer efficiency, and better information-sharing.
Also, Iowas SMS Web site offers considerable data for public
use.
Iowas
Safety Circuit Rider Program, which is operated by Iowa State Universitys
CTRE, provides training at the local level.
The
state has an outstanding Emergency Response Information System that
has identified local emergency response units, their capabilities,
key personnel, contact information, and area of coverage.
Best
Practices in Ohio
The
commitment to safety in Ohio starts with the governor and lieutenant
governor and extends to every level. The goal of the Leadership Team
for Transportation Safety in Ohio is to reduce the number and severity
of crashes on Ohios highways. The state departments of Transportation
and Public Safety and the FHWA Ohio Division are safety partners and
co-signers of a safety charter. The Safety Coordinating Group meets
quarterly to advance the safety program and maintain open lines of
communication with senior officials of all involved agencies.
The
state makes a major effort to build a needs-based program and to target
resources. This is being accomplished through a number of strategic
initiatives, including the development of the Roadway Sufficiency
Index, which gives significant weight to safety. Ohio has systematic
processes in place for identifying locations of frequent crashes;
however, districts are permitted to identify other locations at which
safety improvements are needed.
The
Roadway Analysis for Fatal and Injury Countermeasures (TRAFFIC) project
provides assistance to local governments. TRAFFIC teams perform highway
safety assessments that address the engineering, enforcement, and
emergency medical services of targeted communities.
Ohios
Railroad Grade Separation Program coordinates public and private sector
funding to construct grade separations over a 10-year period. There
is a systematic process for selecting locations.
The
states Highway-Rail Grade Crossings Program includes the following
strengths: the use of a corridor approach to select locations, incentives
to close crossings, the development of a database using digital photographs,
and local/county task forces.
Best
Practices in Oregon
Oregon
has made a major effort to emphasize safety in all projects. The Safety
Investment Program of the Statewide Transportation Improvement Program
provides separate funding to address safety issues on preservation
projects. In addition, safety considerations are identified in all
projects involving the governor and the legislature.
Oregons
Project Safety Management System assists decision-makers in allocating
resources.
The
use of a full-time transportation safety coordinator in each of the
states regions brings the education and enforcement perspectives
to traffic and safety challenges.
The
Oregon Department of Transportation (ODOT) has a good Web site with
extensive information.
Through
the implementation of its TransGIS, ODOT is working to consolidate
all state databases into one GIS-based program and to provide a variety
of reports. It will provide a multitude of data to anyone who is on
the system. For example, designers can easily obtain crash and traffic
data for their projects, and safety personnel will have geometric
and other data available to them to support their prioritization and
selection of projects. Eventually, ODOT hopes to bring its photolog
system and aerial photographs into it.
ODOTs
Countermeasure Analysis Tool, a Web-based system, allows designers
to analyze different alternatives. It provides a good decision-making
tool and can also be used for presentations to the public.
Comments
and Challenges
Overall,
this review identified numerous noteworthy activities related to the
HSIP and safety in general that are being implemented by these states.
In addition to the best practices already noted, the following points
need to be highlighted:
- While
state departments of transportation continue to have the major responsibility
for the HSIP, the implementation of a successful program depends
on good communication, cooperation, and coordination among agencies.
The interaction of various agencies — public and private, state
and local — creates effective partnerships for program development,
advancement, and success. This was evident in the states visited.
- One
key to any successful highway safety improvement program is a knowledgeable,
dedicated, and innovative staff. In all of the states visited, the
review team met excellent safety personnel who had developed and
implemented outstanding programs. The people make the programs.
- The
commitment to continuous process improvement was also evident (e.g.,
revision of policies and implementation of new and innovative programs).
- The
use of advanced and innovative technologies makes safety programs
more efficient and effective.
The
ultimate key to a successful HSIP is ensuring that the best possible
decisions are being made when selecting locations for improvements.
Since the establishment of the Hazard Elimination and Highway-Rail
Grade Crossings Programs, many of the high-incident crash locations
have been addressed. The challenge is to determine the locations with
the highest potential for future crash reductions.
FHWA
has recently awarded a contract for the development of a Comprehensive
Highway Safety Improvement Model (CHSIM). This effort is intended
to assist states and communities in improving their decision-making
processes through the use of a new set of analytical tools designed
for allocating resources to achieve greater safety improvements. CHSIM
will consist of a set of analytical tools designed to:
- Identify
sites with promise (roadway sections and intersections)
that have significant potential for crash reduction.
- Diagnose
safety problems at specific sites.
- Select
effective candidate countermeasures.
- Develop
an economic appraisal.
- Develop
a priority ranking system.
The
complete CHSIM is expected to be developed over a five-year period
and will ultimately be available as a software product for use by
states and communities.
However,
the low-tech activities should not be overlooked. The national safety
review further validated that all agencies and offices involved in
the safety program need to continuously develop, implement, and share
best practices.
