Executive Summary

On behalf of the Rhode Island Department of Transportation (RIDOT) and the Office on Safety we are pleased 

to present the Highway Safety Improvement Program Annual Report for FY22. 

In the past year, RIDOT has continued to make strides in the HSIP, including development of several systemic 

programs; streamlined effort to install countermeasures, and expanded local road program. 

RIDOT has shifted most of our funding to the systemic program to help stretch our limited safety dollars. 

RIDOT develop a systemic, risk based GIS-based tool for both the STEP and Horizontal Curve programs. 

These 2 programs will help address over half of the fatal and serious injury crashes. 

RIDOT also developed a ID/IQ type contract that can streamline the installation of improvements within 3-6 

months from diagnosis as well as help save on overhead costs often seen in larger construction projects. 

RIDOT revised their State TIP to include the MPA starting in FY23. 

RIDOT also began to develop a Local Road program to help locals address safety issues. RIDOT participated 

in a FHWA Local Road Safety Plan workshop and expanded the program in FY22.

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. 

Since 2010, The Rhode Island Department of Transportation (RIDOT) has followed the Highway Safety 

Manual process to guide their HSIP. 

For network screening, RIDOT currently focuses on three programs: Roadway Departure; Pedestrian/Bike; 

and Angle Crashes. 

The roadway departure program uses both systemic, risk based approach for curves and clear zones. Crash 

frequency and SPFs are used to identify hot spots on tangent segments. 

The Ped/Bike program uses a systemic, risk based approach using the STEP tool RIDOT recently developed. 

This tool uses over 20 attributes to assign a risk for each unsignalized crossings. For signalized crossings, 

RIDOT developed a systemic tool in FY22 and will begin to incorporate it into the screening process in FY23. 

The angle crash program currently uses frequency. RIDOT developed a systemic tool in FY22 and will begin to 

incorporate it into the screening process in FY23. 

For diagnosis, RIDOT conducts RSAs at most locations. For systemic treatments (curves, mid-block 

crossing), RIDOT often performs a smaller site visit. 

For countermeasure identification, RIDOT relies on FHWA low-cost proven safety countermeasures, 

NCHRP, FHWA reports, and other safety documents to assist with countermeasure identification. 

Improvements are designed and implemented in 3 ways: RIDOT Maintenance; ID/IQ or Project 

Management. RIDOT Maintenance and MPA allows RIDOT to streamline low-cost improvements (guardrail, 

signage, striping, tree removal) between 1 month and 1 year from diagnosis. Project Management is reserves 

for larger construction projects (roundabout, traffic signal replacement) and can take 1-3 years from diagnosis, 

funding dependent. 

Once completed, the projects are evaluated to determine the safety effectiveness of the safety 

improvements. The resulting data will assist RIDOT with developing their own crash modification factors. 

RIDOT has developed a CMF for Road Diets and is currently developing them for Curve Delineation and High 

Friction.

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

Network Screening

On an annual basis, the RIDOT identifies the roadway facilities exhibiting the most severe safety needs based 

on crash severity and frequency/exposure or the predictive method. Through the RIDOT’s HSIP, ALL public 

roads are addressed, focusing on fatal and serious injury crashes in line with their SHSP and the performance 

measures set forth in MAP-21 and the FAST Act. Most of the State-owned roadway network and some of the 

local roadways are mapped to a Linear Referencing System; however, the majority of the local roadways is not 

referenced and is manually reviewed to ensure their inclusion into the HSIP process.

As part of RIDOT's STEP program, all roadways have been assigned a priority scope based on 20+ 

attributes. RIDOT plans on expanding its other systemic program inventory to local roads in the coming years. 

As part of RIDOT's Horizontal Curve Program, all roadways will be reviewed for conformance.

Diagnosis and Implementation

The RIDOT works with municipalities to identify and mitigate crash issues on locally-maintained roadways. 

RIDOT has developed a process for locals to request a safety improvement with the intent for locals to perform 

the "planning" step from the HSIP process. RIDOT will then determine if the improvement is eligible for HSIP 

funds and distribute the funds needed to the locals so they can administer the construction of the 

improvements.

RIDOT has worked with several municipalities on pedestrian and bicycle safety. They have developed safety 

action plans for multiple communities with high pedestrian activity. RIDOT has also reviewed all segments 

statewide and assigned a "risk" score to them. This will help RIDOT and locals prioritize safety for vulnerable 

road users.

Implementation

To streamline the implementation of Low Cost Safety Improvements on all state and local roads, to reduce 

fatalities and serious injuries, RIDOT will implement ID/IQ contracting in FY2023. This will be funded with HSIP 

funds and will enable RIDOT to reduce project soft costs and accelerate delivery. The Office of Safety will 

administer these contracts with the goal to turn projects around within 6 months to a year from study

Describe coordination with internal partners.

Traffic Safety, Planning, and Operations: RIDOT works internally with transportation planners (RIDOT 

internal and Statewide Planning), RIDOT GIS analysts, RIDOT safety engineers, RIDOT and OHS highway 

safety program coordinators and RIDOT operations staff as part of the entire HSIP process, including the 

identification of critical locations and the selection of appropriate countermeasures/ improvements. These 

partners are involved in Road Safety Assessments (RSAs) that were performed at many of these locations to 

facilitate this multi-discipline approach.

Governors Highway Safety Office: RIDOT also houses the Office of Highway Safety where the HSIP, HSP, 

and SHSP are all developed in a coordinated effort focused on developing consistent safety goals. Safety 

initiatives are now implemented in a more integrated and multi-disciplinary manner, providing RIDOT with more 

flexibility to direct resources to address particular safety needs. RIDOT and OHS along with RI's Office of 

Performance Management coordinated the development of performance measurement and targets for FY23.

Design (Project Management): Office of Traffic Safety also works with the Project Management sections of 

RIDOT in bundle safety projects whenever feasible. These discussion commence at pre-scoping and continue 

thru scoping and final design.

Maintenance: RIDOT Maintenance forces implement the short-term improvements (signing, striping, minor 

signal work) identified by RIDOT Office of Safety from typical reviewed and RSAs. 

Local Aid: RIDOT Office of Safety regularly coordinates with the LTAP to discuss any documented safety 

concerns on local roads and works together to help implement safety infrastructure improvements (incorporate 

into the STIP or to be performed by RIDOT Maintenance) as well as provide training opportunities for locals. 

Identify which external partners are involved with HSIP planning.

• Academia/University

• FHWA

• Law Enforcement Agency

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

• Tribal Agency

Describe coordination with external partners.

LEL and FHWA: Both agencies are involved in bi-monthly safety meetings as well as the SHSP development 

process. They have direct input to the safety decisions the internal partners developed. 

RI MPO: They are involved in the TIP process (specifically for safety projects) as well as the SHSP 

development process. Other MPO studies, such as the Bike Mobility Plan, Transit Master Plan, Long Range 

Transportation Plan, and Congestion Management Plan, are incorporated in the HSIP planning process where 

applicable. 

Tribal: RIDOT address all public roads, including tribal agency roadways. Crashes on locally and tribal owned 

roadways are included in the network screening process. Any safety improvements necessary based on 

prioritization are coordinated with these agencies. Tribal agencies are included in the SHSP planning process 

and are stakeholders on the SHSP steering committee.

Universities: RIDOT Office of Safety works with URI to help fine-tune the HSIP network screening process, 

including development of state-specific SPFs.

Describe HSIP program administration practices that have changed since the last 

reporting period.

RIDOT have expanded their systemic system to signalized intersections to join STEP and horizontal curves. 

The final sub program to have a systemic analysis performed to drive safety decisions is lane departure 

crashes along tangent segments. This is expected to be finalized in FY23.

Program Methodology

Does the State have an HSIP manual or similar that clearly describes HSIP planning, 

implementation and evaluation processes?

Yes

A revision to the program manual is slated for 2023 with the addition of state-specific SPFs and CMFs and 

expanded info on systemic programs. This is currently underway and will be provided when final.

Describe how the State HSIP considers connected vehicles and ITS technologies. 

RIDOT has created a working Connected/Autonomous Vehicle (CAV) group made up of various departments 

with RIDOT including Traffic Safety. RIDOT is exploring CAV and its impact to safety.
2022 Rhode Island Highway Safety Improvement Program

Page 16 of 40

Safety data is being reviewed by the Traffic Safety Section and is discussed as part of the upcoming newly 

developed SHSP CAV Emphasis Area as part of RIDOT's SHSP 5 year update.

RIDOT has placeholders in the TIP for CAV projects related to safety.

All new traffic signals are CAV (V2I) ready. 

RIDOT is exploring pilot programs to incorporate CAV such as over-height detection for bridge strikes, 

automatic horizontal curve detection system, and Wrong Way Driving.

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.

RIDOT refers to the HSM methodologies on all aspects of safety where possible, including in the network 

screening, diagnosis, countermeasure selection, prioritization, and safety effectiveness evaluation categories. 

Please see attached HSIP Program Manual for more information (please note that this is currently being 

updated)

RIDOT has developed two state specific CMFs (Road Diets, and Horizontal Curves)

Describe other aspects of the HSIP methodology on which the State would like to 

elaborate.

RIDOT encourages using the predictive method to use a more sound, data-driven approach to allocating 

resources that results in fewer fatalities and serious injuries on the nation's roadways. The predictive method 

(Excess expected crash frequency using SPFs, EB adjustment,) combines crash, roadway inventory and traffic 

volume data to provide more reliable estimates of an existing or proposed roadway's expected safety 

performance, such as crash frequency and severity. To achieve this goal, RIDOT undertook a large data 

collection effort to obtain all of the Model Inventory of Roadway Data Elements (MIRE), which included 

roadway, traffic, and other data needed to assist the RIDOT make the most efficient decisions where to 

allocate safety funds and resources. The RIDOT also is working on developing a data maintenance effort to 

ensure all data collected is updated on a timely basis. RIDOT has begun using the predictive method for some 

rural segment and will continue to expand in the coming years. RIDOT ahs also used this data to expand their 

systemic programs using risk based analysis. 

RIDOT has also advanced a systemic, risk based analysis for horizontal curves and is currently collecting data 

to advance signalized intersection and roadway departure systemic programs in FY21-22.

RIDOT is expanding its systemic program in the next few years, including creating a detailed risk based 

analysis and process. RIDOT has automated this process by developing a tool that resided on a GIS platform 

for 2 programs (horizontal curves and STEP). The network screening portion of the tool would automate the 

site-specific and systemic identification process which is currently performed manually. For site-specific 

analysis, the tool will use state-specific SPF equations for all facility types, addressing the predictive analysis 

requirements. The tool will provide a list of locations ranked by Excess Excepted Crash Frequency (Expected 

Crashes – Predicted Crashes). The systemic analysis will use allow the user to identify potential trends 

(geometry, traffic volumes) that have a higher occurrence of fatal and serious injury crashes in RI using the 

crash and MIRE data incorporated into the tool. Once the potential trends (aka risk factors) are identified, the 

tool will identify locations that have similar trends which could lead to fatal or serious injury crashes. The user 

can assign a weighted “point “system for each trend to help prioritize locations based on severity or number of 

trends at a given site. This allows the tool to provide the user with a “ranked” list of risk-based locations

RIDOT also has its own HSIP Program Manual. The purpose of this document is to describe RIDOT’s 

processes for planning, implementing, and evaluating HSIP funded improvements and to describe its 

relationship to other safety initiatives found in Rhode Island’s SHSP. This document not only helps Rhode 

Island to demonstrate their own successes, but also serves as a mechanism for other states to achieve 

improved highway safety.

Project Delivery

Currently, RIDOT has two methods for project delivery: state maintenance forces and project management. 

State maintenance forces are used to install basic signing and striping. This enables RIDOT to advance lowcost safety improvements for horizontal curves, pedestrian crossings, and intersections. Any improvements 

beyond this require projects to be programmed in a construction project administered by RIDOT’s Project 

Management section. While larger and complex improvements, such as new traffic signals, roundabouts, and 

high friction treatments require this type of project delivery mechanism, lower cost improvements such as 

RRFBs, signal modifications, guardrail, etc. must wait 2-3 years for programming and often frustrates our 

safety partners in such a delay given the low cost and potential immediate benefit. To help streamline lower 

cost improvements to help drive down fatalities and serious injuries quicker and show action taken to safety 

stakeholders, RIDOT has developed a ID/IQ contract for lower cost improvements to start in FY2023. This will 

be funded with HSIP funds and will enable RIDOT to reduce project soft costs and accelerate delivery. The 

Office of Safety will administer these contracts with the goal to turn projects around within 6 months to a year 

from study.

Stakeholder Outreach

Engage safety stakeholders in a discussion about program needs and potential solutions. Consider talking to 

Highway Safety Office, the MPO, and local agencies.

RIDOT works internally with transportation planners (Statewide Planning), RIDOT GIS analysts, RIDOT safety 

engineers, RIDOT and OHS highway safety program coordinators and RIDOT operations staff as part of the 

entire HSIP process, including the identification of critical locations and the selection of appropriate 

countermeasures/ improvements. These partners are involved in Road Safety Assessments (RSAs) that were 

performed at many of these locations to facilitate this multi-discipline approach. RIDOT also houses the Office 

of Highway Safety where the HSIP, HSP, and SHSP are all developed in a coordinated effort focused on 

developing consistent safety goals. Safety initiatives are now implemented in a more integrated and multidisciplinary manner, providing RIDOT with more flexibility to direct resources to address particular safety 

needs. As part of the FAST Act, the RIDOT and OHS along with RI's Office of Performance Management 

coordinated the development of performance measurement and targets. RIDOT has issues maintaining local 

support for safety projects. Often, over the project development period, local leadership changes and can 

undermine the final delivery of the project. As previously discussed, with the implementing of the Master Price 

Agreement contracts, RIDOT expects a turnaround time within 6 months to a year from study. This will avoid 

most of the conflict of local leadership turnover.

Safety Performance Targets 

Safety Performance Targets 

Calendar Year 2023 Targets *

Number of Fatalities:63.0

Describe the basis for established target, including how it supports SHSP goals.
2022 Rhode Island Highway Safety Improvement Program

Page 28 of 40

Rhode Island has experienced decreases in fatalities in 2021 and looks to be continuing this decrease in 

fatalities in 2022. Additionally, the RIDOT is continuing to support behavioral countermeasures and developing 

low-cost risk-based systemic projects that will target high-risk locations.

Number of Serious Injuries:301.0

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

2021 was the first year in a long time Rhode Island experienced an increase in suspected serious injuries. 

However, early data for 2022 indicate this increase may be an aberration and Rhode Island will continue to 

decrease serious injuries through proposed education and enforcement campaigns as well as infrastructure 

projects.

Fatality Rate:0.830

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

Rhode Island has experienced decreases in fatalities in 2020 and 2021 and looks to be continuing this 

decrease in fatalities in 2022. RIDOT anticipates the planned safety activities will help counteract potential 

increases in fatalities which may be correlated with the projected increase in 2022 and 2023 vehicle-miles 

traveled.

Serious Injury Rate:3.944

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

The projected decrease in serious injuries and increase in vehicle-miles traveled will result in a reduction in the 

serious injury rate in Rhode Island.

Total Number of Non-Motorized Fatalities and Serious Injuries:72.0

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

Rhode Island has experienced notable fluctuations in non-motorist fatalities and serious injuries. However, 

recent years have pointed towards small, steady reductions in these injuries.

Attached is the FFY 2023 Safety Performance Measure Target Setting Memo. 

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

safety performance targets. 

RIDOT Safety, Office of Highway Safety, Office of Performance Management, FHWA, and Statewide Planning 

are all involved in the target setting process. Other safety stakeholders, such as AAA, Growth Smart RI, etc., 

are also involved to some extent. See attached memo that details the 2023 target setting process.

Does the State want to report additional optional targets? 

No
2022 Rhode Island Highway Safety Improvement Program

Page 29 of 40

Describe progress toward meeting the State’s 2022 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 69.0 66.0

Number of Serious Injuries 309.0 305.8

Fatality Rate 0.890 0.867

Serious Injury Rate 3.970 3.970

Non-Motorized Fatalities and 

Serious Injuries

79.0 77.6

The preliminary totals for Rhode Island’s 2021 safety performance measures are 66 fatalities, 306 serious 

injuries, and 78 non-motorized fatalities and serious injuries. According to FHWA Highway Performance 

Monitoring System (HPMS) monthly reports, the total VMT for 2021 results in rates of 0.87 fatalities and 3.97 

serious injuries per hundred million VMT.

Based on this info, Rhode Island will meet all of the State’s 5 safety performance targets. Rhode Island does 

not anticipate any transfers from HSIP. 

The spike in fatalities in 2020 impacted the Fatal, Fatal Rate, and partially effected the Non-Motorized 

performance measures. However in 2021, the downward trend have have seen the past 10 years have 

resumed.

Evaluation

Program Effectiveness 

How does the State measure effectiveness of the HSIP? 

• Change in fatalities and serious injuries 

• Lives saved 

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

the State's program level evaluations. 

As shown in the Progress in Achieving Safety Performance Targets section, RIDOT has see a continuous 

reduction, over a 5 year average, in serious injuries. 

RIDOT tracks crash reductions for all of there HSIP projects. RIDOT uses this data to make changes to a 

specific improvements if desired results are not achieved. 

We have seen reductions in the systemic programs such as Pedestrians, Road Diets, Horizontal Curves, 

Wrong Way Driving. We have also seen direct benefits in spot projects for roadway departure and 

intersections. We continue to tackle the systemic programs with the goal of 100% statewide. 

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

success of the Highway Safety Improvement Program? 

• # miles improved by HSIP 

• # RSAs completed 

• HSIP Obligations 

• More systemic programs 

HSIP obligations have increased over the past 10 years and RIDOT is projected to obligate 100% of the HSIP 

funds in the STIP (10 year plan). 

RSAs are a driver for safety improvements and RIDOT has a streamlined process in place to conduct RSAs 

and implement the findings in with maintenance forces, ID/IQ contract, or bundle with capitol projects. 

RIDOT has expanded its HSIP to have 4 systemic sun-programs: STEP, Horizontal Curves, Signalized 

Intersections, and Lane Departure: Tangent Sections. RIDOT is developing an Unsignalized Intersection 

systemic analysis i FY23. 

We fell that the shift to primarily all systemic projects will help reduce fatal and serious injury related crashes 

proactively statewide.

*Based on Functional Classification (MIRE 1.0 Element Number) [MIRE 2.0 Element Number]

Preliminary numbers. Will be updated at part of final report once RIDOT completed the ongoing MIRE update slated to be wrap up in 1-2 weeks. 

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. 

RIDOT is applying for various grants to complete the collection by 2026. RIDOT collected most of the data in 2016 as part of the MIRE data collection effort, however local data for some elements were not collected as part of this effort 

due to funding. Also, traffic data is being collected under a standalone effort.
