Executive Summary

This report provides an overview of SCDOT's administration of the Highway 

Safety Improvement Program (HSIP). SCDOT's HSIP has a primary focus on 

state-maintained roads since nearly 96 percent of fatal crashes and the vast 

majority of severe crashes occur on the state system. This report covers 

funding obligations from January 1, 2016 to December 31, 2016.

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 Reporting Guidance dated December 

29, 2016 and consists of five sections: program structure, progress in implementing highway safety 

improvement projects, progress in achieving safety outcomes and performance targets, effectiveness of the 

improvements and compliance assessment.

Program Structure

Program Administration

Describe the general structure of the HSIP in the State. 

The Highway Safety Improvement Program is implemented through the Traffic Engineering-Traffic Safety Office. This 

office is composed of five groups: Highway Safety Improvement Program, Railroad/Research, Safety Program 

Administration, Safety Project Development, and Strategic Highway Safety Plan/Special Projects. The HSIP group is 

responsible for all aspects of the HSIP process: planning, implementation, and evaluation.

Describe how local and tribal roads are addressed as part of HSIP.

In South Carolina, the vast majority (~96%) of fatal crashes occur on state-maintained roadways. Due to this 

statistic, our primary focus for safety has been on state-maintained roadways. However, we have recently 

planned for some intersection improvement projects where a local road intersects with a state-owned 

road. Additionally, as our crash data is improving in accessibility and completeness, we will incorporate local 

roads into our safety funding if a viable need is observed. 

It is also worth noting that South Carolina maintains the fourth largest highway system in the nation at nearly 

41,400 center-line miles of roadway, despite a land area of roughly 32,000 square miles.

Describe coordination with internal partners.

Several partners within SCDOT and consultants are involved thoughout the process of HSIP planning. Many of 

our safety improvements are designed by our Safety Project group within Traffic Engineering and they 

are involved with project design or oversight on all projects to ensure proper designs. Our Planning office is 

consulted during the selection process to determine if any qualifying projects have been identified for 

improvements through other funding sources such as the Metropolitan Planning Organizations (MPOs) or 

Council of Governments (COGs). Our Maintenance office is also contacted to ensure that there are no 

conflicting maintenance activities such as resurfacing or pavement marking contracts that involve overlapping 

work. Operations are monitored through other Traffic Engineering offices or consultants to ensure that all 

projects include consideration of proper traffic operations by conducting traffic volume counts, Synchro 

analysis, signal operations, etc.

their full time efforts to the enforcement of traffic laws along high crash corridors in the states. The corridors were 

identified based upon crashes that involved an impaired driver, speeding or unrestrained motor vehicle occupants.

The SCDOT Traffic Engineering Safety Office also provides annual reports on MPO/COG specific crash statistics, and 

location specific crash summaries and analyses as needed. Additionally, SCDOT will often partner with MPOs, COGs and 

LGAs to ensure safety improvements are included in projects. 

Have any program administration practices used to implement the HSIP changed since the last reporting 

period?

No

Are there any other aspects of HSIP Administration on which the State would like to elaborate?

Yes

Highway Safety Improvement Program Process

Every state is required by the federal government to administer a Highway Safety Improvement Program 

(HSIP). Part 924 of Title 23 of the Code of Federal Regulations (CFR) states, in part:

924.5 Policy. “Each state shall develop and implement, on a continuing basis, a highway safety improvement 

program which has the overall objective of reducing the number and severity of accidents and decreasing the 

potential for accidents on all highways.”

924.7 Program Structure. “The highway safety improvement program in each state shall consist of 

components for planning, implementation, and evaluation of safety programs and projects.”

The purpose of the South Carolina HSIP is to establish guidelines for the effective use of available funds, to 

reduce the number and severity of crashes and to decrease the potential for crashes on highways in the state. 

The program consists of the following three components: planning, implementation, and evaluation.

1. PLANNING 

a. Data Management 

In order to locate hazardous locations the following information is essential:

• Crash data - Crash reports are provided by DPS. 

• Traffic data - Traffic volumes are provided by the Traffic Engineering.

• Roadway Data - Road characteristics are provided by the Traffic Engineering.
2017 South Carolina Highway Safety Improvement Program

Page 8 of 70

b. Identify Hazardous Locations

Using the information listed above, potential locations are identified by:

• Recommendations from SCDOT and FHWA personnel.

• Requests from governmental units other than SCDOT and FHWA.

• Requests from citizens.

• Ongoing research of the HSIP database.

The HSIP database has been established to identify, prioritize, and provide guidance for selecting potential 

projects. The information gathered for a location is analyzed using the following methods: 

• Crash Rate - Equates frequency of crashes to traffic volumes (and length of roadway if section). A 

typical crash rate would be expressed in # of crashes per million vehicles entering (if intersection) or per 

one hundred million vehicle miles of travel (if section).

 Severity Rate - A weighted calculation for determining the severity of the crashes. It is based on the 

EPDO (Equivalent Property Damage Only) method from studies performed by the National Safety Council and 

the Traffic Institute at Northwestern University. The severity indices used are listed below: (from the Traffic 

Institute at Northwestern University)

Fatality = 12

Injury = 3

Property Damage Only = 1

• Rate Quality (SPFs)

This method entails the calculation of the crash rate at each location and a statistical test to determine if that rate 

is significantly higher than crash rates for other locations with similar characteristics.

The critical rate is compared to the actual crash rate for each location. If the actual crash rate exceeds the 

critical rate, then the location may be considered for improvement. 

• Number-Rate 

Combines crash frequency and crash rate methods by first ranking by the number of crashes. Establishes a 

frequency threshold and then re-ranks the locations. Based on a crash rate threshold, locations with lower crash 

rates are eliminated. 

c. Conduct Engineering Studies 

Once a potential project location has been identified, the following steps are taken to determine if geometric 

improvements can be implemented that will reduce the volume and severity of the crashes reported at the 

location. 

• Analyze Project Location
2017 South Carolina Highway Safety Improvement Program

Page 9 of 70

Crash reports are obtained and analyzed for locations selected for detailed review. Results from analyses along 

with engineering judgment are used to determine if further investigation is needed along with site review.

• Develop Candidate Countermeasures and Project Proposals

Site reviews are conducted to determine characteristics of locations relative to types of crashes occurring. 

Improvements are recommended to address patterns in crashes. 

• Establish Project Priorities 

Estimate costs for recommended improvements at each site along with expected reduction in crashes for these 

improvements. Summarize estimated costs and benefits for improvements and determine the most cost effective 

improvement alternative for a location using the Net Benefit Method along with engineering judgment.

The net benefit method compares the estimated annual costs of implementing the selected countermeasure to 

the expected annual benefits. The expected annual benefit is calculated using the most current “comprehensive 

costs” of motor vehicle traffic crashes and the estimated crash reduction percentage expected as a result of 

implementing the selected countermeasure.

Comprehensive costs are a measure of motor vehicle accident costs that include the effects of injury on people's 

entire lives. This is the most useful measure of accident cost since it includes all cost components and places a 

dollar value on each one. Comprehensive life values are estimated by examining risk reduction costs from 

which the market value of safety is inferred. The 11 components of the comprehensive cost are: property 

damage, lost earnings, lost household production, medical costs, emergency services, travel delay, vocational 

rehabilitation, workplace costs, administrative, legal, pain, and lost quality of life. 

2. IMPLEMENTATION 

Given that the overall charge of the HSIP program is to reduce the number and severity of crashes, it is 

imperative that the implementation phase be carried out in a timely manner. Once the project has been approved 

for funding, it is necessary to design and schedule the project to implement the improvements. All HSIP 

Projects are managed by one of the following offices:

• Preconstruction 

• Traffic Engineering 

• Consultant

Given the appropriate conditions, a Participation Agreement may be arranged with other governmental entities. 

A participation agreement is a contractual partnership between the SCDOT and one or more other governmental 

entities where funding is combined to complete a project. The agreement includes the specifying of the roles, 

responsibilities, and financial obligations of each participant. 

3. EVALUATION 

 To Determine the Effect of Highway Safety Improvements 
2017 South Carolina Highway Safety Improvement Program

Page 10 of 70

Before and After Studies are conducted on all HSIP projects to evaluate the effectiveness of the overall 

program by observed changes in crash number, rate and severity resulting from program implementation. The 

HSIP office conducts studies three years after final inspection of a project. The studies include:

• After a period of no less than 3 years after the completion of the project, crash data and the most recent 

traffic volumes are collected for the location.

• The data collected before implementing safety improvements is then compared with the data collected 

after the improvements have been completed.

• The information described above is used to calculate the resulting crash rate reduction factor for the 

improved site. The total cost of the project along with the reduction factor is used to conduct a Benefit 

Cost Analysis to determine the overall effectiveness of the project.

In past years, all non-state owned roads were categorized as "Other." Since this category is no longer available 

and SCDOT does not have records showing ownership, all non-state owned roads have been shown as "Other 

Local Agency."

Are there any other aspects of the general highway safety trends on which the State would like to 

elaborate?

able to determine a reasonable target for the five year period ending in 2018. By 

examining planned projects and current safety initiatives (in the fields of education, 

enforcement, and engineering), the state was able to calculate an expected decrease in 

the fatality rate during calendar year 2018. This target supports the SHSP goal of 

eliminating traffic fatalities in SC. 

Number of Serious Injuries 3067.0 

Describe the basis for established target, including how it supports SHSP goals. 

A target of 3067 severe injuries was established after thorough analysis of historic data 

and trend line projections. For this measure, a polynomial order 2 trend analysis was 

used to determine projected 2017 data, then using this projection the state was able to 

determine a reasonable target for the five year period ending in 2018. By examining 

planned projects and current safety initiatives (in the fields of education, enforcement, 

and engineering), the state was able to calculate an expected decrease in severe 

injuries during calendar year 2018. This target supports the SHSP goal of reducing 

serious injuries that resulted from a traffic collision. 

Fatality Rate 1.810 

Describe the basis for established target, including how it supports SHSP goals. 

The target of 1.810 as the fatality rate was established by using the target fatality 

number in 2018 along with an expected 2% increase in vehicle miles traveled during 

that year. As part of the SHSP, reducing the fatality rate remains a valuable target for

the state. 

Serious Injury Rate 5.708 

Describe the basis for established target, including how it supports SHSP goals. 

The target of 5.708 as the serious injury rate was established by using the target severe 

injury number in 2018 along with an expected 2% increase in vehicle miles traveled 

during that year. As part of the SHSP, reducing the number of serious injuries remains 

a valuable target for the state. 

Total Number of Non-Motorized 

Fatalities and Serious Injuries 371.3 

Describe the basis for established target, including how it supports SHSP goals. 

The target of 371.3 non-motorized fatalities and serious injuries was established after 

thorough analysis of historic data and trend line projections. For this measure, a 

polynomial order 2 trend analysis was used to determine projected 2017 data, then 

using this projection the state was able to determine a reasonable target for the five 

year period ending in 2018. By examining planned projects and current safety 

initiatives (in the fields of education, enforcement, and engineering), the state was able 

to calculate an expected decrease in fatalities and serious injuries involving 

pedestrians and bicyclists during calendar year 2018.

Describe efforts to coordinate with other stakeholders (e.g. MPOs, SHSO) to establish safety performance 

targets. 

When setting safety performance targets for the state, extensive analysis of the data related to each measure 

was performed by statisticians from both the State Highway Safety Office with the SC Department of Public 

Safety (DPS) and the traffic engineering office with the SC Department of Transportation (DOT). After the data 

had been thoroughly examined and documented, representatives from each agency, including the State 

Traffic Safety Engineer from DOT and the Director of the State Highway Safety Office from DPS, meet on two 

separate occasions to discuss safety initiatives planned for the upcoming years that may counteract the rising 

number of fatalities in the state.

Agreement was reached between the two agencies on the expected reductions and targets were established.

Staff from the traffic engineering office also met with representatives from the MPO/COGs, delivering a 

presentation on target setting and how the state’s targets were established for this year.

Does the State want to report additional optional targets?

Describe actions the State will take moving forward to meet the requirement to have complete access to the MIRE fundamental data elements on all public roads by September 30, 2026.

Of the 33 unique MIRE FDE identified, South Carolina currently collects 88%, missing only 4 elements (unique junction identifier, intersection/junction traffic control, unique interchange identifier, and interchange type). Capturing the 

remaining elements will be accomplished through several avenues. Modifying existing road inventory databases to capture these elements will begin in 2017. Additionally, the state Traffic Records Coordinating Committee has identified 

approximately the following projects that can assist in completing the FDE: Intersections with Traffic Signals Database, Local Agency Data Collection, and Horizontal Roadway Curve Identification.

Provide the suspected serious injury identifier, definition and attributes used by the State for both the crash report form and the crash database using the table below. Please also indicate whether or not these elements are 

compliant with the MMUCC 4th edition criteria for data element P5. Injury Status, suspected serious injury.
