Executive Summary

Louisiana has set an aggressive target for reducing death and injury on the roadways –Destination Zero 

Deaths. Great progress has been made since the development and implementation of the 2006 Strategic 

Highway Safety Plan (SHSP) and its subsequent update in October, 2011 and July, 2017. The 2017 SHSP 

targets five emphasis areas: impaired driving, occupant protection, infrastructure and operations, crashes 

involving young drivers and distracted driving. Although preliminary, Louisiana is showing 2019 as the first 

decrease in annual fatalities since 2013. Louisiana remains below our SHSP target of reducing fatalities in half 

by 2030. Louisiana has accomplished a number of successes in each emphasis area including the following:

Infrastructure and Operations (I/O) Data and Analysis improvements

We continue to use state specific safety performance functions to develop annual network screening lists for 

state owned segments and intersections. These Safety Performance Functions (SPFs) are integrated into our 

Crash Analysis Tool (CAT Scan) for engineers and planners across the state to use for project level safety 

analyses. This year we completed two Districtwide Safety Investment Plans (Districts 07 and 08) which 

analyzed safety data for top locations on statewide network screening lists (also known as High Potential for 

Safety Improvement List). The consultant in coordination with District office and Highway Safety office 

performed high level planning safety analysis, countermeasure selection, and planning level cost estimates to 

recommend potential safety countermeasures. The final product includes a prioritized list of potential safety 

projects based on planning level safety benefit cost ratios.

LADOTD continues to support Regional Safety Coalitions (RSC) /Metropolitan Planning Organizations (MPOs) 

and Local Technical Assistance Program (LTAP) for developing local road safety plans targeted for the top 20 

parishes, where over 90% of crashes are occurring on local roads, to better inform the data-driven process and 

target more data driven safety projects. Of the top 20 parishes, 10 local road safety plans have been finalized 

and 12 plans are currently under development. Each Regional Safety Coalition has a goal of completing at 

least one local road safety plan within each region as part of the SHSP Statewide I/O Emphasis Area Action 

Plan. We continue to use crash frequency for network screening on local roads. Crash data profiles which were 

developed by LTAP are being used by non-top 20 parishes (remaining 10% of crashes are occurring on local 

roads) to determine potential safety projects for Local Road Safety Program (LRSP). This year we have also 

identified potential locations where Highway Safety Improvement Program (HSIP) could partner with Pavement 

Preservation Program to use High Risk Rural Roads (HRRR) funds using safety data and SHSP high risk rural 

road definition.

Our office participated in FHWA’s HSIP Implementation Plan workshop and used this guidance to prepare our 

first formal Louisiana HSIP Implementation Plan. As part of the planning and coordination for the 

Implementation Plan, our office conducted 9 highway safety road shows in conjunction with SHSP I/O Regional 

Emphasis Area (EA) team meetings. The purpose of these meetings was to give updates on crash data based 

on I/O EA subcategories (roadway departure, intersections, and non-motorized users), statewide safety 

performance measures, Draft HSIP Implementation Plan, HSIP project selection guidelines for infrastructure 

projects, and goals for future HSIP funding allocations based on subcategories.

The MPO Safety Performance Target Setting web based portal has been updated for MPOs to use as part of 

the outreach at the regional level. Many of the MPOs are using this portal within their committee meetings to 

present and discuss safety data and targets at the state and regional level;

LADOTD is collaborating with local agencies to identify a process to review data items that have been 

collected as well as incorporate new construction of roads and their data elements. From 2015-2017, LADOTD 

collected all known public roads during statewide efforts to satisfy FHWA requirements to report on all roads. 

At that time, it was approximated that 99% (90% of Fundamental Data Elements (FDE) are completed) of all 
2020 Louisiana Highway Safety Improvement Program

Page 5 of 44

local public roads were collected. All state owned roads and their data elements are actively maintained within 

LADOTD’s enterprise GIS system. LA

LADOTD is working through Linear Referencing System (LRS) issues with the local road system in order to 

have them loaded into the GIS system. Many efforts are underway to determine which elements are accessible 

and useable for ongoing safety studies through published GIS services.

Louisiana released the Louisiana Roadway Departure Implementation Plan (RwD-P) and interactive tools at 

the 2020 Louisiana Transportation Conference and the Statewide District Roadshows. The implementation of 

the plan will reduce 19-20 fatal roadway departure crashes per year for a five-year time period at a cost of $26 

million per year. Advanced predictive methods for network screening of locations with potential for safety 

improvement on all public roads, including safety performance functions, were included in the plan. As 

roadway departure crashes account for over 50% of Louisiana’s fatal crashes, implementation of this plan over 

the next five years will move Louisiana closer to meeting their safety performance targets. LADOTD is working 

with FHWA and LTAP to develop a specific roadway departure training to locals which will include how to 

identify locations from the Implementation Plan for in-house development or HSIP Local Road Safety Program 

applications.

We have provided input for law enforcement training program on the updated crash report manual which 

included new definitions for coding injuries using KABCO scale. We have also shared data gaps we have 

identified based on the manual review we performed on the pedestrian crashes from 2012-2017 with our SHSP 

Law Enforcement Experts. As a result, they are highlighting pedestrian crashes as part of their trainings.

LADOTD Highway Safety Section worked with LSU/Center for Analytics and Research in Transportation Safety 

(CARTS) to roll out a new Crash Data Query Tool for project level safety analysis using more mapping features 

and tying directly to the electronic captures of narratives and diagrams of the crash reports. The tool allows the 

engineer or planner to query a specific location and view crash data elements at summary level or at the crash 

level. Outputs of the tool include summary tables, detailed data tables, and collision diagrams. This tool is 

currently in demonstration mode and is being used by internal LADOTD staff. Next steps include building in 

permissions for external users (local public agencies, MPOs, researchers and consultants).

Louisiana is currently in the process of updating the Louisiana Uniform Motor Vehicle Traffic Crash Report to 

include more data elements and attributes from NHTSA’s Model Minimum Uniform Crash Criteria (MMUCC) 

5th Edition. LADOTD has contracted with a Law Enforcement Expert to lead this effort between all lead 

agencies (Louisiana State Police (LSP), Louisiana Highway Safety Commission (LHSC), LSU/CARTS, FHWA, 

and LADOTD) and ensure crash data quality improvements are being tracked and data integration is optimized 

on the front end. Connecting systems on the back-end are also being planned for smooth transition to a new 

schema and updated data query tools for users. Training plans are underway as well for local law enforcement 

agencies and outreach through the RSC has begun.

We are continuing to implement cable barrier projects statewide based on a statewide systemic cable median 

barrier study which produced a prioritized list of candidate locations where median barrier would be considered 

for installation. High speed, controlled access facilities with a median width less than 100' were analyzed in the 

study. As of June 2020 the LADOTD has installed approximately 392 miles of cable barriers throughout the 

State at an investment of approximately $57 million. There are currently another 365 miles under construction 

along I-10, I-59 and I-49, I-220, US 190, and I-12 corridors for approximately $36 million.

The first round of districtwide low cost safety improvement systemic projects targeted at curves for roadway 

departure were implemented within the last 3 years. We have started the process of determining methodology 

for evaluating these projects when 3 years of crash data is available.

The state is updating the specification on High Friction Surface Treatment again to provide the best possible 

application and road treatment for our motorists.

LADOTD Highway Safety Office and Traffic Office have partnered together to fund enhanced signing at curves 

on rural two-lane roads. We anticipate having this complete for MUTCD deadline. We are working with LTAP 

for a similar initiative on local roads in conjunction with rural roadway departure EDC.

Local Road Safety Program (LRSP): Louisiana continues to lead efforts in LRSP. The LRSP is allocated 

approximately $3-5 million of HSIP funds per year. Eligible projects include those for roadways in 

transportation systems owned and operated by Parish and municipal road agencies. Specific funds are 

available for selected local safety data-driven projects and additional funding sources for resources may be 

available depending on the type of project. Funding for local road safety improvement projects is available 

through the LRSP.LADOTD administers the LRSP in coordination with LTAP. LTAP coordinates activities and 

resources in conjunction with the LADOTD to facilitate quarterly project submittals, review and scoring, and 

recommendation of qualifying project applications for the Local Road Safety Improvement projects. This year, 

LTAP with LADOTD support has hosted webinars, meetings and peer exchanges with the RSC Coordinators 

on Local Road Safety Plans. LTAP continued working with the RSC Coordinators with developing Local Road 

Safety Plans in at least one parish per Coalition.

Additionally, LADOTD and LTAP participated in FHWA Local Road Safety Peer Exchanges in September 2019 

and January 2020.

Non-Motorized Users: As part of EDC 5, Safe Transportation for Every Pedestrian (STEP), LADOTD is leading 

a project with LSU/CARTS to analyze non-motorized user crashes between 2012-2017. Additional crash data 

elements not currently captured on the crash report are being complied based on narrative and diagram. We 

anticipate this crash data assessment will give us more insight into trends and patterns statewide. This will also 

help us focus our safety funds and determine which countermeasure we should target and where we should 

focus training. Unfortunately, the quality of the data sets were not 100% complete for many roadway 

characteristics including ADT, pedestrian exposure and local road attributes across the entire network 

especially for locally owned roadways at the time of project kick off. However, we have been able to access 

other data sets related to pedestrian exposure and preliminary findings show statistically significant predictors 

for pedestrian crashes include percent of no-vehicle households, percent of households below poverty line, 

percent eligible persons employed, number of sub segments within 1⁄4 mile of school or daycare, and 

population density. We participated in a Pedestrian Systemic Crash Data Workshop hosted by EDC 4 DDSA 

Initiative FHWA which helped guide the methodology and process flows for this project. We anticipate to have 

a draft report prepared by the end of 2020.

The Safe Routes to Public Places Program (SRTPPP) is allocated approximately $3-5 million per year as part 

of the HSIP. Eligible projects include those roadways in transportation systems owned and operated State, 

Parish and municipal road agencies with an emphasis on reducing non-motorized fatalities and serious 

injuries. Specific funds are available for selected safety data-driven projects and additional funding sources for 

resources may be available depending on the type of project. Funding for these projects is available through 

the SRTPPP. LADOTD administers the SRTPPP. LADOTD coordinates activities and resources to facilitate 

yearly project application submittals, review and scoring, and recommendation of qualifying project 

applications. Due to a lack of resources to manage and deliver projects a call for projects was not held 

between July 2019 and June 2020. LADOTD plans to conduct a call for projects in 2020 as additional 

resources become available.

LADOTD prepared the annual statewide Complete Streets Performance Measures Report and is working 

towards action items listed in Complete Streets Implementation Plan. Safety considerations have been used 

for these efforts to help bring awareness to potential concerns and identify opportunities where improvements 

can be made on new projects. LADOTD Highway Safety Section participates in LADOTD Complete Streets 

Steering Committee and the Louisiana Complete Streets Advisory Council.

Under the FHWA Focused Approach for Pedestrians and Bicyclists, LADOTD consultant completed a Bicycle 

and Pedestrian Safety Action Plan for the City of Baton Rouge and Masterplan for the Parish of East Baton 

Rouge. The Safety Action Plan prioritizes locations for safety improvements as part of a larger recommended 

network for the entire City-Parish. Next steps include conducting Road Safety Assessments for the top 10 

locations identified in the Safety Action Plan and prioritizing infrastructure projects and enforcement and/or 

education strategies through the Regional SHSP Pedestrian and Bicycle Emphasis Area Team. 

Occupant Protection 

In 2019, observational surveys showed that 87.5 percent of all Louisiana drivers and passengers were wearing 

their seat belts. The State of Louisiana’s statewide seat belt use rate increased in 2019 at 87.5 percent from 

86.9 percent in 2018.

The Louisiana Passenger Safety Task Force (LPSTF), a subgroup under the Occupant Protection Emphasis 

Area in the SHSP, are responsible for educating the community and other agencies on the benefit of restraint 

systems in motor vehicles. The LPSTF is hosted by the University Medical Center New Orleans and the LHSC. 

Louisiana’s RSCs partner with LPSTF many efforts including education, enforcement, and legislation related to 

motor vehicle occupants, thus preventing unnecessary injuries, fatalities, and economic costs to society. We 

work together to provide access to child passenger safety and adult occupant protection services at no cost to 

all citizens of Louisiana. During 2019, 6,300 children were assisted among Louisianan’s 112 fitting stations. 

During the 2019 Legislative Session, LPSTF, Statewide Emphasis Area Teams and RSCs worked together on 

the passage of the Child Passenger Safety Law. Our law now mirrors that suggested by the American 

Academy of Pediatrics, placing children in the safest category while traveling in a vehicle. 

Young Drivers 

Through the Young Driver SHSP Emphasis Area Team, LADOTD partnered with Office of Motor Vehicles 

(OMV), LSP and LHSC to revise the State's 30-hour novice driver education curriculum and to deliver a 

complete comprehensive curriculum, with lesson plans, to the State. This effort was completed this year and 

has been handed over the OMV for implementation. Louisiana’s Statewide Emphasis Area Teams and 

Regional Safety Coalitions work closely with the Sudden Impact Program (comprehensive injury prevention 

program targeting adolescents). The program reached just over 18,560 students during 2019. 

Impaired Driving 

LHSC continues to support DWI overtime enforcement in Tier One Alcohol Problem ID Parishes corresponding 

with national and state mobilizations. There are a total of eight DWI courts serving clients in twelve parishes 

throughout the state. No Refusal Programs continue to be expanded across the state with assistance from LSP 

and RSCs. An additional 28 law enforcement officers were trained as Drug Recognition Experts, and the state 

launched its first Judicial Outreach Liaison program. 

LADOTD continues to participate in the Governor's Task Force on DWI which is being managed within the 

Governor’s Office of Drug Policy. LADOTD and LHSC as well as SHSP Impaired Driving Team Leader serve 

on the task force and have presented on the SHSP and SHSP Impaired Driving Action plan.

SHSP Planning 

The SHSP Implementation Team oversees overall implementation of the Plan and is supported by an 

Executive Committee. The team consists of representatives from LADOTD, LSP, LHSC, LTAP, Louisiana 

Planning Council (LPC), Louisiana Municipal Association (LMA), FHWA, Federal Motor Carrier Safety 

Administration (FMCSA), National Highway Traffic Safety Administration (NHTSA), in addition to the statewide 

emphasis area team leaders and regional safety coalition coordinators. RSCs through a partnership with 

MPOs, we established nine regional transportation safety coalitions across the State. Led by safety coalition 

coordinators housed within each of the MPOs and championed by leaders from a range of agencies and 

organizations, each coalition comprises local experts and advocates working toward the development and 
2020 Louisiana Highway Safety Improvement Program

implementation of regional safety plans based on the SHSP. This regional, grassroots, 4E approach 

(engineering, enforcement, education, and emergency response) to saving lives has proven to be highly 

effective.

Louisiana is using a two-tiered approach to implement the SHSP: Statewide Emphasis Area Teams create 

data-driven action plans and track implementation of SHSP strategies and action steps, and RSCs utilize data 

to identify regional safety needs and develop data-driven five-year regional safety plans which identify 

emphasis areas consistent with the SHSP. 

In 2019, Louisiana implemented a newly developed vision for implementing and evaluating progress of 

emphasis area action plans. LADOTD collaborated with federal, state, regional, and/or local representatives in 

the implementation of new program content relating to the performance, quality and compliance monitoring of 

action plans, projects and/or processes that will further enhance and support the engagement, effectiveness, 

tracking, goals and objectives of the SHSP and its associated operative platforms. Strategies were 

implemented, outcomes were defined, performance indicators were identified, and action plans were 

implemented. Quarterly and annual reviews are conducted at the statewide and regional levels to evaluate 

attainment, ensure action plans are data driven and are enhancing effectiveness of overall goal achievement. 

In 2019, Louisiana’s achieved 82 percent attainment for all emphasis areas (combined). The majority of action 

steps that were unattainable were related to legislation and budget.

In 2019, LADOTD hosted Louisiana Highway Safety Summit with 300 safety professionals in attendance.

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. 

Projects that are identified through the Highway Safety Improvement Program (HSIP) have the overall goal of 

reducing the number of fatalities and serious injuries on all public roads. LA DOTD performs HSIP components 

of planning, implementation, and evaluation to accomplish requirements of the program. These components 

involve the following: data-driven identification of crash locations, development and implementation of an 

annual program of projects and report annually to the FHWA on progress and effectiveness. FHWA is involved 

in all three components, both formally and through informal technical assistance. LADOTD has developed 

SRTPPP Guidelines, LRSP Guidelines and HSIP Infrastructure Project Selection Guide for State Routes. 

Please see the attached documents that explain how HSIP projects are identified, selected, designed, 

implemented and evaluated. 

Where is HSIP staff located within the State DOT? 

 Planning

How are HSIP funds allocated in a State? 

• Central Office via Statewide Competitive Application Process 

• SHSP Emphasis Area Data 

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

Local Road Safety Program (LRSP) LRSP is allocated approximately $3-5 million per year. Eligible projects 

include those for roadways in transportation systems owned and operated by Parish and municipal road 

agencies. Tribal lands are also eligible. Specific funds are available for selected local safety data-driven 

projects and additional funding sources for resources may be available depending on the type of project. 

Funding for local road safety improvement projects is available through the LRSP. 

LADOTD administers the LRSP in coordination with LTAP. LTAP coordinates activities and resources in 

conjunction with the LADOTD to facilitate quarterly project submittals, review and scoring, and 

recommendation of qualifying project applications for the Local Road Safety Improvement projects. LA DOTD 

is responsible for managing project delivery once a project is accepted into the LRSP. LTAP hosted webinars, 

meetings and peer exchanges with the Regional Safety Coalition Coordinators on Local Road Safety Plans. 

LTAP continued working with the Regional Safety Coordinators with developing Local Road Safety Plans in at 

least one parish per Coalition. Additionally, LADOTD and LTAP participated in FHWA Local Road Safety Peer 

Exchanges in September 2019 and January 2020. LADOTD has bundled similar types of LRSP projects within 

the same region to increase efficiency and reduce costs. 
2020 Louisiana Highway Safety Improvement Program

Safe Routes to Public Places Program (SRTPPP) 

SRTPPP is allocated approximately $3-5 million per year as part of the HSIP to focus on improving safety of 

non-motorized users. Eligible projects include those roadways in transportation systems owned and operated 

State, Parish and municipal road agencies. Specific funds are available for selected safety data-driven projects 

and additional funding sources for resources may be available depending on the type of project. Funding for 

these projects is available through the SRTPPP. 

LADOTD administers the application process and project delivery for SRTPPP. LADOTD coordinates activities 

and resources to facilitate yearly project application submittals, review and scoring, and recommendation of 

qualifying project applications. Due to a lack of resources to manage and deliver projects a call for new 

projects was not held between July 2019 and June 2020. LADOTD plans to conduct a call for new projects in 

2020 as additional resources become available. 

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

Bureaus, Divisions) are involved with HSIP planning. 

• Design 

• Districts/Regions

• Operations 

• Planning 

• Traffic Engineering/Safety 

Describe coordination with internal partners. 

LADOTD Design Engineers assists with HSIP by providing quality reviews of scope, budgets, and design 

alternatives considered during feasibility stage as needed. LADOTD pavement preservation group assists with 

prioritizing HRRR funds using safety data. LADOTD Districts perform an annual review of High Potential Safety 

Improvement List (HPSI List) and prioritizes potential safety projects within each district. Once locations are 

identified, they perform crash data analysis to select appropriate countermeasures and prepare scope and 

budget for proposed alternatives, including economic evaluation. LADOTD Planning unit assists with feasibility 

studies which in turn provides guidance as to whether or not a project is a good fit for the safety program. 

LADOTD Traffic Engineering unit provides input and feedback regarding safety intersection improvements 

such as traffic signals and roundabouts. LADOTD Operations Unit's guidance and feedback is sought when a 

statewide, systemic approach has been identified as a safety improvement and will require long-term 

commitment to maintain (guardrail upgrades, cable barrier, etc.). 

Identify which external partners are involved with HSIP planning. 

• Academia/University 

• FHWA 

• Governors Highway Safety Office 

• Law Enforcement Agency 

• Local Government Agency 

• Local Technical Assistance Program 

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

• Other-State Police 

Describe coordination with external partners. 

About 25 percent of roadway deaths and 40 percent of all crashes in Louisiana occur on the local road system. 

LADOTD partnered with the Louisiana LTAP to manage the LRSP to provide training, technical assistance, 

and outreach to local jurisdictions through an application process. LHSC is actively involved in the 

development of the SHSP particularly the emphasis area plans. As such, the projects and activities funded by 
2020 Louisiana Highway Safety Improvement Program

Page 11 of 44

the Highway Safety Plan (HSP) are reflected in these emphasis area action plans. The second goal in 

Louisiana’s Statewide Transportation Improvement Plan (STIP) is coordinated with the HSIP and SHSP to 

provide safe and secure travel conditions across all transportation modes through physical infrastructure 

improvements, operational controls, programs, and public education and awareness. One of the ways to 

achieve this goal is through the objective of reducing the number and rate of highway-related crashes, 

fatalities, and serious injuries, which corresponds to the performance targets for the HSIP and HSP and the 

measurable objectives in the SHSP. A review of the Commercial Vehicle Safety Plan (CVSP) found several 

areas that link to the SHSP including removing alcohol- and drug-impaired commercial vehicle operators from 

the road and outreach and education on seat belt use. LADOTD works closely with FHWA division office on 

statewide and regional initiatives related to SHSP strategies and HSIP, in particular those related to safety data 

and planning and HSIP infrastructure projects. LADOTD has also been in contact with one of the state’s tribes 

for information on HSIP funding opportunities in Louisiana. This year two tribes in Louisiana were awarded 

grants from USDOT Travel Transportation Program Safety fund for conducting RSA's and safety plans. 

Regional Safety Coalitions are providing support as needed for these tribal grants. Local and state law 

enforcement agencies actively participate in the statewide SHSP emphasis area teams and the regional safety 

coalitions. Their involvement is critical as SHSP strategies are initiated and achieved at the regional level. 

Their participation is also key for statewide safety initiatives/campaigns. In addition, the law enforcement 

agencies participate in the Road Safety Audits. LADOTD also employs two law enforcement experts to lead 

crash report update project and to assist with trainings and outreach to the various law enforcement agencies 

statewide to increase the quality of data. Additional duties include Traffic Incident Management and Work Zone 

law enforcement training. Regional Metropolitan Planning Organizations (MPO) are actively engaged within the 

regional safety coalitions. Each MPO employs a safety coalition coordinator to oversee the activities of each 

coalition. The planning organizations also work with the LADOTD planners to use safety and roadway data for 

their internal analyses and assist with their internal prioritization of projects.Many of the MPOs have committed 

to developing local road safety plans at parish level and reaching out to local entities to discuss potential 

opportunities for addressing safety concerns. CARTS provides assistance to LADOTD for Fatal Accident 

Reporting System (FARS), crash report software development and training, crash database management, data 

quality reviews, and real-time reporting tools for stakeholders. CARTS also conducts specialized crash data 

analysis studies as requested by LHSC, LADOTD, or LSP.

Does the State HSIP consider connected vehicles and ITS technologies? 

No

Does the State use the Highway Safety Manual to support HSIP efforts? 

Yes 

Please describe how the State uses the HSM to support HSIP efforts. 

The Highway Safety Manual (HSM) was consulted for determining better methodologies for network screening 

and project level data analysis. Louisiana has developed state-specific safety performance functions and 

excel-based diagnostic tools for better targeting HSIP funds. Additionally, LADOTD utilizes the HSM 

spreadsheets and CMF Clearing House for project level safety analysis.

How much funding was transferred out of the HSIP to other core program areas during 

the reporting period under 23 U.S.C. 126?

$0

The HRRR is the same amount for 2 years and we did not transfer any out of HSIP to any other programs.

Discuss impediments to obligating HSIP funds and plans to overcome this challenge in 

the future.

LADOTD has no impediments to obligating funds.

Describe any other aspects of the State’s progress in implementing HSIP projects on 

which the State would like to elaborate. 

The reason for the difference between our programmed and obligated amounts is that our programmed 

projects are those formally accepted into the HSIP by project selection committee within the current year. 

Obligated amounts are for projects authorized within the current year and are programmed prior to the current 

year. Also, cost tend to increase once design begins and leads to higher obligations closer to construction.

2020 Louisiana Highway Safety Improvement Program

Page 31 of 44

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

The overall goal is to reduce fatal and serious injury crashes on Louisiana roadways. As mentioned previously, 

LHSC and LADOTD teamed up to identify consistent goals to be adopted by both agencies. The two agencies 

agreed to adopt the American Association of State Highway and Transportation Officials (AASHTO) goal of 

halving fatalities by 2030. Louisiana’s SHSP, which the LADOTD oversees, reflects this overall goal as well. 

Despite an increasing trend in fatalities and serious injuries over the last few years, it was decided to renew the 

commitment to saving lives and continue to set decreasing targets. LADOTD reviewed the actual and linear 

trend of fatalities, fatality rate, serious injuries, serious injury rate and the statewide non-motorized fatalities 

and serious injuries over 5 year moving periods dating back to 2005. Trends were evaluated to determine if a 

linear trend could be established and carried through 2021. In most cases, a linear trend-derived target was 

adopted. These targets are less aggressive than in years past and represent a 1% annual decrease from the 

most current 5-year average. Based on historical data, 2019 was the first year with a sizable reduction in total 

fatalities from 771 in 2017 and 2018 to 727 in 2019. A steady percentage based reduction was chosen as the 

most practical justification for determining the 2021 target. To achieve the 2021 target, fatalities will have to be 

reduced by two percent from 756 (2015 to 2019 average) to 741.0 in 2021.

Number of Serious Injuries:1319.0

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

The overall goal is to reduce fatal and serious injury crashes on Louisiana roadways. As mentioned previously, 

LHSC and the LADOTD teamed up to identify consistent goals to be adopted by both agencies. The two 

agencies agreed to adopt the AASHTO goal of halving fatalities by 2030. The SHSP, which the LADOTD 

oversees, reflects this overall goal as well. Despite a relatively steady number of suspected serious injuries 

over the last few years, it was decided to renew the commitment to saving lives and continue to set decreasing 

targets. LADOTD reviewed the actual and linear trend of fatalities, fatality rate, serious injuries, serious injury 

rate and the statewide non-motorized fatalities and serious injuries over 5 year moving periods dating back to 

2005. Trends were evaluated to determine if a linear trend could be established and carried through 2021. In 

most cases, a linear trend-derived target was adopted. These targets are less aggressive than in years past 

and represent a 1% annual decrease from the most current 5-year average. Serious injuries have fluctuated 

over the last five years and have decreased from a five-year high of 1398 in 2016 to a five-year low of 1262 in 

2018. However, 2019 showed an increase in serious injuries which we attribute to the adoption of new serious 

injury code definitions. A five-year average trend line was chosen as the most practical justification for 

determining the 2021 target. To achieve the 2021 target, serious injuries will have to be reduced by two 

percent from 1346 (2015 to 2019 average) to 1319.0 in 2021.

Fatality Rate:1.496

the probable increase in vehicle miles driven. To achieve the 2021 target, the fatality rate per 100 MVMT will 

have to be reduced by 2.0 percent from 1.526 (2015 to 2019 average) to 1.496 in 2021.

injuries rate which we attribute to more reported serious injuries based on new injury code defintions. The 1% 

decrease was chosen despite the probable increase in vehicle miles driven. To achieve the 2021 target, the 

serious injury rate per 100 MVMT will have to be reduced by 2.0 percent from 2.719 (2015 to 2019 average) to 

2.664 in 2021.

Total Number of Non-Motorized Fatalities and Serious Injuries:359.0

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

The overall goal is to reduce fatal and serious injury crashes on Louisiana roadways. This goal is especially 

critical for our most vulnerable non-motorized users, a population that has seen rapid growth in recent years. 

As mentioned previously, LHSC and the LADOTD teamed up to identify consistent goals to be adopted by both 

agencies. The two agencies agreed to adopt the AASHTO goal of halving fatalities by 2030 for all road users. 

The SHSP, which the LADOTD oversees, reflects this overall goal as well. Despite an increase in fatalities and 

serious injuries over the last few years, it was decided to renew the commitment to saving lives and continue to 

set decreasing targets. LADOTD reviewed the actual and linear trend of fatalities, fatality rate, serious injuries, 

serious injury rate and the statewide non-motorized fatalities and serious injuries over 5 year moving periods 

dating back to 2005. Trends were evaluated to determine if a linear trend could be established and carried 

through 2021. In most cases, a linear trend-derived target was adopted. These targets are less aggressive 

than in years past and represent a 1% annual decrease from the most current 5-year average. Non-motorized 

user fatalities and serious injuries have decreased in 2019 to 375 after an all-time high (since tracking began in 

2005) of 417 in 2018. However, as practical solutions are implemented and as awareness is heightened we 

feel confident that a 1% decrease annually can be realized. To achieve the 2021 target, the non-motorized 

users fatalities and serious injuries will have to be reduced by 2.0 percent from 366 (2015 to 2019 average) to 

359.0 in 2021.

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

safety performance targets. 

With guidance from LADOTD, CARTS has developed web-based dashboard to support safety performance 

management and target setting and state and regional levels. This dashboard calculates the five year 

averages for the performance measures and provides VMT data, all of which can be broken down by state or 

MPO area. They can also be used to calculate a linear trend forecast. Although, the regional safety coalitions 

represent larger geographic areas than the MPOs, they are implementing consistent target setting for the 

entire region. As evidence, statewide emphasis area teams are using the performance measures as outputs on 

their statewide emphasis area action plans. The teams are tracking performance measure targets as output 

measures for fatalities and serious injuries by specific emphasis area. These output measures are directly 

correlated to the State’s over all performance measure targets (e.g. the output measure for impaired driving 

serious injuries is a 1% reduction, which is the same target as the statewide serious injuries target). The 

regional safety coalitions are using the same output measures for their regional emphasis area action plans as 

the statewide plans. By all emphasis area action plans, both state and regional, using the performance 

measure targets as output measures, specific areas of need by both problem and geographic area can be 

identified and addressed. Louisiana has chosen this methodology to reach their annual targets of reducing 
2020 Louisiana Highway Safety Improvement Program

Page 33 of 44

fatalities and serious injuries on Louisiana’s highways, as well as their overall goal of halving fatalities by 50% 

by 2030. For annual performance targets the LHSC has used three and five-year average linear trends to set 

targets. Generally they have used three-year averages, which has better R-squared values indicating how well 

the trend line fit the data. For some emphasis areas, such as non-motorized crashes, they have chosen a 

target of maintenance of the same value. In the future, LHSC targets for the common measures will need to be 

set using five-year rolling averages to be in alignment with the FHWA rule and so LADOTD/SHSO targets will 

be identical. LADOTD and LHSC have been working together for the past several years to obtain agreement 

on targets. They have reviewed trends using three and five year averages and chosen targets based on the 

trend line that seems most reasonable based on the R-squared and the annual percentage reduction required 

to meet the target. Once LADOTD and LHSC agree on targets, they are communicated to SHSP State and 

Regional Leaders. According to the Planning Final Rule (Statewide and Nonmetropolitan Transportation 

Planning; Metropolitan Transportation Planning Final Rule issued May 27, 2016) Metropolitan Transportation 

Plans (MTPs) will need to discuss how the plan will achieve safety targets. The MPOs Transportation 

Improvement Program (TIP) and the Statewide Transportation Improvement Program (STIP) also must discuss 

how they will achieve targets. Every MTP update will include development of a System Performance Report, 

which will state what targets are and whether the region achieved targets. Safety performance management 

happens annually. However for other performance measures it will not be reported annually. The review of 

MPO target achievement will be part of FHWA planning process reviews. Any needed changes will happen 

within the planning process review. There is no consequence for MPOs in the Federal legislation. MPOs will 

report their targets (either targets specific to the region or support of the five State safety targets, or a 

combination of the two) to the LADOTD in writing. A formal memo is issued to MPO Directors from LADOTD 

each Fall with details on state targets, link to web-based dashboard and requirements for MPO target setting.

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.

Number of fatalities: Louisiana did not achieve the 2019 safety performance target for total fatalities. Louisiana 

did however experience a 5.7% decrease in roadway-related fatalities in 2019, marking the lowest total number 

of fatalities since 2013. The result is that the 2019 fatalities did achieve the safety performance target of 730 

though the 5-year average was 755.6 due to increases in 2017 and 2018. Louisiana continued to see progress 

on motor vehicle occupant fatalities compared to previous years. Had significant progress been made in 

reducing pedestrian fatalities, the 201 target may have been achieved. Moving forward, we will be looking at 

these user groups independently and adjusting our safety performance targets accordingly. 

Suspected Serious Injury: Louisiana did not achieve the 2019 safety performance target for suspected serious 

injury. In 2019, Louisiana updated its definition of serious injury to conform to the Model Minimum Uniform 

Crash Criteria Guideline and as expected Louisiana suspected serious injuries increased from the previous two 
2020 Louisiana Highway Safety Improvement Program

Page 34 of 44

years due to the new definition encompassing a wider type of injury than the previous definition. Fatality Rate 

Louisiana did not achieve the 2019 safety performance target for total fatality rate. Louisiana did however 

experience a 5.7% decrease in total fatality rate in 2019, marking the lowest rate on record. This is primarily 

due to Louisiana experiencing the lowest total fatalities since 2013 despite consistently increasing vehicle 

miles traveled across the state. The result is that the 2019 fatality rate did achieve the safety performance 

target of 1.506 though the 5-year average was 1.526 due to increases in past years.

Fatality Rate: Louisiana did not achieve the 2019 safety performance target for total fatality rate. Louisiana did 

however experience a 5.7% decrease in total fatality rate in 2019, marking the lowest rate on record. This is 

primarily due to Louisiana experiencing the lowest total fatalities since 2013 despite consistently increasing 

vehicle miles traveled across the state. The result is that the 2019 fatality rate did achieve the safety 

performance target of 1.506 though the 5-year average was 1.536 due to increases in past years.

Suspected Serious Injury Rate: Louisiana has achieved the 2019 safety performance target for suspected 

serious injury rate. This is primarily due to a decrease in suspected serious injuries across the state in 2017 

and 2018 coupled with an increase in vehicle miles traveled over the same period. In 2019, Louisiana updated 

its definition of serious injury to conform to the Model Minimum Uniform Crash Criteria Guideline and as 

expected Louisiana suspected serious injuries increased in 2019 due to the new definition encompassing a 

wider type of injury than the previous definition. 

Non-motorized Fatalities & Suspected Serious Injuries: Louisiana did not achieve the 2019 safety performance 

target for non-motorized fatalities and suspected serious injuries. This is primarily attributed to an upward trend 

in pedestrian fatalities and serious injuries despite ongoing efforts to improve safety infrastructure and promote 

awareness for non-motorized users that has continued again in 2019. Additionally in 2019, bicyclist fatalities 

decreased from a high in 2018 and bicyclist serious injuries were the highest experience since 2005. Louisiana 

needs to continue making major investments to non-motorized user infrastructure and improve safety culture to 

make significant progress towards improving transportation safety for these user groups.

Applicability of Special Rules

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

Yes

We looked at State routes using 2018 ADT, 5yrs crash data (2014-2018), functional classification of Rural 

Major Collector or Minor Collector where the crash rate for fatalities and sever injuries exceed the statewide 

average. It can also be roadways where traffic volumes are likely to increase creating a crash rate for fatalities 

and severe injuries that exceed the statewide average. The HRRR project is identified in the project listing 

(Q29) and in the funding summary table (Q23).

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

years of age and older for the past seven years.

Evaluation

Program Effectiveness 

How does the State measure effectiveness of the HSIP? 

• Change in fatalities and serious injuries 

• Other-Change in all crashes at locations in the HSIP 

Based on the measures of effectiveness selected previously, describe the results of 

the State's program level evaluations. 

Based on 2019 statewide crash data, we have observed a decline in total roadway fatalities and an increase in 

serious injuries. We believe this fatality reduction is due to a more focused approach on roadway departure 

projects in recent years. We attribute the increase in overall serious injuries to the adoption of the new serious 

injury code definitions in 2019. We have seen a significant increasing trend in non-motorized fatalities and 

serious injuries. We have initiated a crash data assessment on non-motorized users over the last 5 years to 

gain insight into potential causes and strategies to address this and align more future HSIP projects with 

emphasis on non-motorized users. Also, before/after crash rate evaluations were calculated for eight 

completed HSIP Safety Projects with Final Inspection dates in 2016 and where traffic data was available. The 

eight projects were broken down into 12 sites; 2 intersections and 10 segments. Overall, we saw a combined 

crash rate reduction of 55% for total crashes. As seen in Q44, it appears from crash data that roadway 

departure, impaired driving, and young driver fatalities showed a decrease for a 5 year average. The five 

performance measures are tracked by SHSP emphasis area and documented on the annual statewide 

regional action plans. 

What other indicators of success does the State use to demonstrate effectiveness and 

success of the Highway Safety Improvement Program? 

• HSIP Obligations 

• Increased awareness of safety and data-driven process 

• Increased focus on local road safety 

• More systemic programs 

• Policy change

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. 

Between 2012 and 2016, DOTD collected roadway attribute data for all public roads including those that are locally classified. This process involved the use of a Data Collection Vehicle that captured video imagery. MIRE FDEs that could 

be captured from video were included in the data delivery. The raw data has been made available to local agencies as DOTD develops methods to maintain the road centerline and attribute data that are not owned by the State. During 

this time frame, an Enterprise GIS system is being implemented in order to manage and properly distribute the data using an established Linear Reference System. DOTD is coordinating an effort with the Acadiana Planning Commission 

to establish standards and protocols for obtaining updates from local agencies. This includes developing a data dictionary, complete with schema and domain values. The raw attribute data for the non-state system has been translated to 

include the Linear Reference System established by the Enterprise GIS. The data has been loaded into the Enterprise, DOTD has begun publishing GIS data and maps to an Open Portal site that can be shared and used for collaboration 

purposes. https://data-ladotd.opendata.arcgis.com/ 

Items outside of the collection scope include traffic volume information as well as unique identifiers for intersection attributes. While DOTD has an extensive Traffic Monitoring Program for State Highways, it continues to study the use of 

vehicle probe data in order to acquire complete AADT coverage on locally classified roads. Additional efforts are underway within GIS to establish intersection identification and create unique identifiers for attaching related data items.
