Executive Summary

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) 

o Interstate Safety Program ($11M) 

o 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. 
2020 South Carolina Highway Safety Improvement Program

Page 6 of 54

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. 

 FHWA 

 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 Safety 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 2021 Targets *

Number of Fatalities:1005.0

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

The target of 1005.0 traffic fatalities was established after thorough analysis of historic data and trend line 

projections. For this measure, a polynomial order 2 trend analyses was used to determine projected 2020 data, 
2020 South Carolina Highway Safety Improvement Program

Page 42 of 54

then using this projection the state was able to determine a reasonable target for the five year period ending in 

2021. 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 2021. This target supports the SHSP goal of eliminating traffic fatalities in SC.

Number of Serious Injuries:2950.0

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

A target of 2950.0 serious injuries was established after thorough analysis of historic data and trend line 

projections. For this measure, a polynomial order 2 trend analyses was used to determine projected 2020 data, 

then using this projection the state was able to determine a reasonable target for the five year period ending in 

2021. 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 

2021. This target supports the SHSP goal of reducing serious injuries that resulted from a traffic collision.

Fatality Rate:1.760

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

The target of 1.670 as the fatality rate was established by using the projected fatality number in 2021 along 

with an expected 3% 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:5.350

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

The target of 5.350 as the serious injury rate was established by using the projected serious injury number in 

2021 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:440.0

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

The target of 440.0 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 analyses was used to 

determine projected 2020 data, then using this projection the state was able to determine a reasonable target 

for the five year period ending in 2021. 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 2021.

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

safety performance targets. 

South Carolina established a coordinating group comprised of highway safety professionals from the SC 

Department of Transportation (SCDOT) and the SC Department of Public Safety, which houses the State 

Highway Safety Office. This group meets to discuss the historical and current trends as well projections related 

to the five safety performance areas. Staff from SCDOT is available to provide any information related to the 

safety targets, including baseline data, to all MPOs.

Does the State want to report additional optional targets? 

No

Describe progress toward meeting the State’s 2019 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.

PERFORMANCE MEASURES TARGETS ACTUALS

Number of Fatalities 988.0 1005.8

Number of Serious Injuries 2986.0 2986.6

Fatality Rate 1.790 1.816

Serious Injury Rate 5.420 5.438

The state anticipates meeting two of the five safety performance targets for 2015-2019.

Performance Area: Fatalities

The target number of fatalities was 988.0, the actual number was 1005.8.

Discussion

When the state was setting targets for the 2015-2019 performance period in early 2018, the projected number 

of fatalities for 2018 was much lower than the actual number for that year. The previous year (2017) had 

experienced a 3% decline in traffic fatalities from 2016 and the trendline, along with programmatic effects, led 

the state to set a lower annual target for both 2018 and 2019. Instead of the expected reduction in 2018, the 

state experienced a 4.75% increase before decreasing again in 2019 by 3%. Also see discussion on 

pedestrian deaths below. The pedestrian representation of total fatalities in SC increased to 16% in 2019 and 

17% in 2019.

Performance Area: Fatality Rate

The target fatality rate was 1.790, the actual number was 1.816.

Discussion

This measure is directly related to the number of fatalities and VMT in the state. See fatality discussion for 

more information.

Performance Area: Serious Injuries

The target number of serious injuries was 2986.0, the actual number was 2986.6.

Discussion

The state met this target.

Performance Area: Serious Injury Rate
2020 South Carolina Highway Safety Improvement Program

Page 44 of 54

The target serious injury rate was 5.420, the actual number was 5.438

Discussion

The state did not met target.

Performance Area Non-motorized User Fatalities + Serious Injuries

The target number of non-motorized (ped/bike) fatalities and serious injuries combined was 380.0, the actual 

number was 412.2.

Discussion

SC experienced a record high number of pedestrian fatalities in 2018; unfortunately that trend continued in 

2019 leading the state to miss its target. A report by the Governor’s Highway Safety Association cites a 

number of factors that might have played a role in the increasing pedestrian deaths seen across the nation. 

Among those are: increased exposure, unsafe driving behavior, and an increased presence of SUVs. The 

same report points to possible infrastructure improvements that could lead to safer roadways for non-motorized 

users.

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. 

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.
