Executive Summary

In 2005, the Safe, Accountable, Flexible, and Efficient Transportation Equity Act: A Legacy for Users 

(SAFETEA-LU) established the Highway Safety Improvement Program as a core Federal-aid program with the 

goal of achieving a signification reduction in fatalities and serious injuries on all public roads under Section 

148, Title 23 of the United States Code (23 USC 148). The program has continued through the enactment of 

the Moving Ahead for Progress in the 21st Century Act (MAP-21) in 2012 and the Fixing America's Surface 

Transportation Act (FAST Act) in 2015.

The Highway Safety Improvement Program (HSIP) emphasizes a data-driven, performance-based strategic 

approach to improving highway safety, through the development and implementation of a Strategic Highway 

Safety Plan (SHSP), a comprehensive plan that establishes statewide highway safety goals, objectives, and 

key emphasis areas intended to drive HSIP investment decisions.

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, 2018 to December 31, 2018

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.

HSIP funding is currently allocated to align with crash categories and emphasis areas from the Strategic 

Highway Safety Plan (SHSP). The funding for these Emphasis area is as follows with some overlap between 

categories: 

• Roadway Departure ($20 Million) 

• Interstate Safety Program ($11M) 

• Rumble Strip Program ($9M) 

• Intersections and Other High Risk Locations ($18 Million) 

o Intersection Safety Program ($13M) 

o Road Safety Assessments Program ($5M) 

• Non-Motorized Users ($5 Milliion) 

Where is HSIP staff located within the State DOT? 

 Engineering

How are HSIP funds allocated in a State? 

• Other-Central Office through Statewide Screening Process

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 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, local roads are being incorporated into our Road 

Inventory Management System (RIMS) for analysis. 
2019 South Carolina Highway Safety Improvement Program

Page 6 of 34

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.

Identify which internal partners (e.g., State departments of transportation (DOTs) 

Bureaus, Divisions) are involved with HSIP planning. 

• Design

• Districts/Regions

• Local Aid Programs Office/Division

• Maintenance

• Operations

• Planning

• Traffic Engineering/Safety

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. 

Identify which external partners are involved with HSIP planning. 

• Governors Highway Safety Office

• Law Enforcement Agency

• Local Government Agency 

• Regional Planning Organizations (e.g. MPOs, RPOs, COGs)

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.

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 biennial basis.

Safety Performance Targets

Safety Performance Targets 

Calendar Year 2020 Targets *

Number of Fatalities:1011.0

Describe the basis for established target, including how it supports SHSP goals.
2019 South Carolina Highway Safety Improvement Program

Page 22 of 34

The target of 1011.0 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 

projected 2019 data, then using this projection the state was able to determine a reasonable target for 

the five year period ending in 2020. 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 2020. This target supports the SHSP 

goal of eliminating traffic fatalities in SC.

Number of Serious Injuries:2781.0

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

A target of 2781.0 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 2019 data, then using this projection the state was able to determine a reasonable target for 

the five year period ending in 2020. 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 2020. This target supports the SHSP goal of 

reducing serious injuries that resulted from a traffic collision.

Fatality Rate:1.819

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

The target of 1.819 as the fatality rate was established by using the projected fatality number in 2020 

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:4.979

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

The target of 4.979 as the serious injury rate was established by using the projected serious injury 

number in 2020 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 2019 data, then using this projection the state was able to 

determine a reasonable target for the five year period ending in 2020. 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 2020.
2019 South Carolina Highway Safety Improvement Program

Page 23 of 34

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? 

No

Describe progress toward meeting the State’s 2018 Safety Performance Targets (based 

on data available at the time of reporting). For each target, include a discussion of any 

reasons for differences in the actual outcomes and targets. 

The state anticipates meeting four of the five safety performance targets for 2014-2018. The preliminary five 

year averages for each measure are shown below. The target is shown in parenthesis after each target figure. 

Fatalities: 969.6 (970.0)

Fatality Rate: 1.804 (1.810)

Serious Injuries: 2,961.6 (3,067.0)

Serious Injury Rate: 5.545 (5.710)

Non-motorized user fatalities and serious injuries combined: 380.8 (371.0) 

The number of non-motorized user fatalities and serious injuries combined is the only target the state does not 

anticipate meeting.

Applicability of Special Rules

Does the HRRR special rule apply to the State for this reporting period? 

No 

Provide the number of older driver and pedestrian fatalities and serious injuries 65 

years of age and older for the past seven years.

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.

There 4 items we are currently missing:

• Unique Junction Identifier (120) 

• Intersection/Junction Traffic Control (131) 

• Unique Interchange Identifier (178) 

• Interchange Type (182) 

The software changes to accommodate these 4 items are scheduled to be completed by February 2020. 

• The software will assign a unique Junction Identifier to each intersection, so item 120 should be completed by the 1st quarter of 2020. 

• Once the software is in place, we plan to begin collecting the information for item 178 and 182 manually using ITMS and aerial imagery. It may take up to a year to get all of them entered, so the estimated completion date for items 

178 and 182 is the 1st quarter of 2021. 

• The software changes will also accommodate item 131, and data collection methods are currently being evaluated. 

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

A gap analysis and assessment was conducted in 2017. Results and improvements from the gap analysis will be reported in the 2019 HSIP report.
