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, 2017 to December 31, 2017.

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.

Describe coordination with external partners.

SCDOT has partnered with the SC Department of Public Service to fund a Target Zero enforcement initiative. 

Through this partnership, a specialized enforcement team comprised of 24 Highway Patrol Troopers has been 

deployed to focus 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.
2018 South Carolina Highway Safety Improvement Program 

Page 7 of 51

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. 

The Traffic Safety office conducts safety data workshops with MPO's and COGs on a bi-annual basis. 

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?

Safety Performance Targets

Safety Performance Targets

Calendar Year 2019 Targets * 

Number of Fatalities 988.0 

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

The target of 988.0 traffic fatalities 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 project 2018 data, then using this projection the state was able 

to determine a reasonable target for the five year period ending in 2019. 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 number of

traffic fatalities during calendar year 2019. This target supports the SHSP goal of 

eliminating traffic fatalities in SC. 

Number of Serious Injuries 2986.0 

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

A target of 2986.0 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 2018 data, then using this projection the state was 

able to determine a reasonable target for the five year period ending in 2019. 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 

serious injuries during calendar year 2019. This target supports the SHSP goal of 

reducing serious injuries that resulted from a traffic collision. 

Fatality Rate 1.790 

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

The target of 1.790 as the fatality rate was established by using the target fatality 

number in 2019 along with an expected 1% 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 5.420 

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

The target of 5.420 as the serious injury rate was established by using the target 

serious injury number in 2019 along with an expected 1% increase in vehicle miles 

traveled during that year. As part of the SHSP, reducing the serious injury rate remains 

a valuable target for the state. 

Total Number of Non-Motorized 

Fatalities and Serious Injuries 380.0 

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

The target of 380.0 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 2018 data, then 

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

year period ending in 2019. 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 2019.

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.

States are required to have access to a complete collection of Model Inventory of Roadway Elements (MIRE) fundamental data elements (FDE) on all public roads by September 30, 2026. Of the 33 unique MIRE FDE identified, the South 

Carolina Department of Transportation currently has access to 87.9%, missing only four elements. The state has identified and prioritized the collection of the remaining MIRE FDE. Several projects in the state’s Traffic Records Strategic 

Plan address improvements to the collection of MIRE FDE. Specifically, Collision Report Form Revision, Intersections with Traffic Signals Database, Local Agency Data Collection for Road Location Coding, Rural/Urban Designation and 

Roadway Surface Type Database, Horizontal Roadway Curve Identification, Roadway Shoulder/Width Data Cleansing, Traffic Records Dashboard, and Posted Speed Limit Project. SCDOT’s Roadway Inventory Division is coordinating 

with the Traffic Records Coordinating Committee on the projects listed above. Data elements that are not planned for as part of these projects will be collected through SCDOT efforts directed by the Roadway Inventory Division.

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.

Please describe the actions the State is taking to become compliant by April 15, 2019.

The state’s Traffic Collison Report Revision Committee has been tasked by the state’s Traffic Records Coordinating Committee (TRCC) to revise the state’s collision report form. While a complete revision will not be done before the 

deadline stated above, a small revision will be made to the injury severity section of the crash report, crash manual, and data dictionary by January 1, 2019 in order to maintain an entire year’s worth of the new definition. The Revision 

Committee will ensure this change will bring the state in compliance with the federal mandate.

Did the State conduct an HSIP program assessment during the reporting period?

Yes

Describe the purpose and outcomes of the State’s HSIP program assessment.

The purpose of the review was to evaluate the procedures and operations of the HSIP program. The Gap Analysis was performed to identify any process or procedure that would improve the efficiency of the HSIP program. The Gap 

Analysis is currently underway and many of the identified issues have been addressed. We are continuing to work on further improvements.
