Executive Summary

The reporting period for 2019 is from October 1, 2017 to September 30, 2018. Connecticut's (5 year rolling 

average) fatalities and fatal crash rates have increased in 2017. Both (5 year rolling average) serious injuries 

and the serious injury crash rate have seen little change in 2017. Connecticut uses HSIP resources to 

incorporate safety improvements across a broad range of maintenance, safety and non-infrastructure projects. 

Innovative methodologies developed and used by CTDOT will continue to identify more locations, on a 

statewide scale, with the greatest potential for crash reduction. Applications of new Highway Safety Manual 

concepts and systemic approaches are also being integrated into the HSIP program. The SHSP 

implementation plan will target goals and devise strategies in each emphasis area to see where improvements 

can be made in order to support the vision of moving towards zero deaths. In the next fiscal year, CTDOT 

hopes to solicit a greater number of off system (non-state highway) locations with high potential for crash 

reduction with the help of local agencies partners and stakeholders.

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. 

CTDOT's Safety Engineering Section, which is located within the Division of Traffic Engineering, Bureau of 

Engineering and Construction utilizes both the spot improvement approach and the systemic approach to 

identify, select, implement HSIP projects. The spot improvement approach, known as High Frequency Crash 

Locations (HFCL) results in safety investments at specific locations while the systemic approach leads to 

widespread implementation of treatments to reduce the potential for fatalities and/or serious injuries, whether 

or not crashes have occurred at any given site. Since many of CT's fatal and serious injury crashes are spread 

out across all public roads, the systemic approach provides an alternate method to identify and implement lowcost safety countermeasures addressing specific risk factors across the entire roadway network. As data 

becomes available, spot improvement projects are evaluated to determine their effectiveness.

Where is HSIP staff located within the State DOT? 

 Engineering

How are HSIP funds allocated in a State? 

• SHSP Emphasis Area Data 

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

Local Roads are addressed by the Local Road Safety Program (LRSP). The LRSP provides federal funding for 

safety-related improvements on the non-state maintained roadways, to address hazardous elements identified 

at locations and along roadway sections. To address all public roads requirement, Regional Transportation 

Safety Plans (RTSP) are being prepared for each of the nine regional councils of government (COG). The 

RTSPs identify key safety issues for all public roads. The plans utilize a similar to the Connecticut’s Strategic 

Highway Safety Plan (SHSP) but focused instead on the local and regional level needs of the individual 

communities and region as a whole. Since RTSPs include all public roads, communities will be made aware of 

potential or emerging safety issues on locally owned and maintained roadways and recommendations on how 

to address them. Once all nine RTSPs have been finalized, there will be a new application process for HSIP 

projects off the state system. Project sponsors will be encouraged to examine a full range of options starting 

with low-cost spot and systemic treatments such as signs and pavement markings, to mid-range solutions such 

as traffic signals, turning lanes or roadway realignment. The applications will be reviewed and evaluated based 

on factors such as crash analysis, regional or local priority, and benefit/cost analysis. Additional program

details will made available at a later date. 

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

Bureaus, Divisions) are involved with HSIP planning. 

• Design

• Maintenance

• Operations

• Traffic Engineering/Safety

Describe coordination with internal partners. 

The Operations' Section within the Department's Division of Traffic Engineering reviews specific spot locations 

on the state highway system for possible highway safety improvements. The study locations typically originate 

from internal databases, such as High Frequency Crash Locations (HFCL) lists or via appointed and elected 

officials, town officials, or the public. Depending on the cost and scope of the countermeasure, the CTDOT’s 

Office of Maintenance may be requested to implement low-cost improvements such as traffic signal timing 

changes, as well as installation of signs and pavement markings. In those situations where the scope of work 

is beyond the resources of maintenance, the Operations’ Section recommends a project for inclusion in the 

CTDOT’s capital improvement plan. These safety projects are further developed and plans, specifications, and 

estimates are undertaken by the Department's Division of Highway Design.

Identify which external partners are involved with HSIP planning. 

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

• Other-Safety Circuit Rider Program

Describe coordination with external partners. 

Regional Transportation Safety Plans (RTSP) are being prepared for all nine Council of Governments (COGs) 

in CT. Once the plans are complete, the COGS will solicit member towns for candidate HSIP projects. CTDOT 

plans to evaluate all the projects received and will notify the COG if the project is selected for funding. The 

COG's will inform the member towns accordingly. 

The Department's Safety Section works in partnership with the CT's Safety Circuit Rider Program (CT SCR) 

which provides safety-related information, training, and technical assistance to local agencies. Some of the 

initiatives include coordination of Road Safety Assessments (RSA’s), collection and analysis of traffic volume 

data, identification of low cost safety improvements, assistance in the development of Local Road Safety 

Plans, development of a Connecticut Toolbox of Safety Resources, development of a series of Roadway 

Safety Briefs, and delivery of Local Road Safety Training. The CT SCR program also provides assistance to 

local agencies in understanding the capabilities of the new CT Crash Data Repository at the University of 

Connecticut (UCONN) and provides accurate information to local practitioners to make informed roadway 

safety decisions.

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

elaborate. 

Projects can qualify for the Department's HSIP funds and placement on the HSIP Safety Project Plan when 

they are initiated from the following sources:

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. 

CTDOT, in partnership with UCONN, is currently updating the agency's safety analysis tools and methods to 

match the six-step safety management process as described in the HSM. CT's Roadway Safety Management 

System (CRSMS) has a network screening module which is used to identify and rank sites with a higher than 

predicted crash frequency for specific roadway types, crash types, or the presence of a specific traffic control 

device. In the diagnosis module, users are able to create collision diagrams and crash trees as well as conduct 

a test of proportions. Condition diagrams are also available to provide a visual site overview and can be used 

in coordination with the collision diagram. CTDOT is also using IHSDM in the safety planning process to 

evaluate and compare design alternatives.

Describe program methodology practices that have changed since the last reporting 

period. 

The CT Roadway Safety Management System (CRSMS) is constantly being updated to provide more features 

and better user experience.

Annual data for the number of fatalities, fatality rate, and number of non-motorized fatalities between 2010 and 

2017 was updated from the latest available FARS data. Annual data for the number of serious injuries, serious 

injury rate and number of non-motorized serious injuries between 2010 and 2017 was updated from the 

UCONN crash data repository. Also, the 2018 performance measures data for fatalities and serious injuries is 

from the UCONN crash data repository and is preliminary.

FARS is the source for the number of fatalities based on functional class. The source of data for HMVMT is 

FHWA Table VM-2. Table VM-2 was not available for 2016 & 2017 when data was entered into the OLT so 

2015 data was used instead. HMVMT has not varied much in the last several years.

The state's crash file does not have serious injury crash data broken down by functional class so those 

columns are blank.

The state's crash file is the data source for the number of fatalities and serious injuries on roadway ownership 

in 2018.

Safety Performance Targets

Safety Performance Targets 

Calendar Year 2020 Targets *

Number of Fatalities:277.0

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

• There were 278 Fatalities in 2017, a single year decrease from the 304 recorded in 2016. • Although 

the single year fatality total decreased, the five-year average continued to rise to 277 in 2017. • The 

most current preliminary data show there were 297 Fatalities in 2018, a single year increase from the 

278 recorded in 2017. The 2018 five-year moving average value of 279 also represents an increase 

from the previous year. This figure is also the highest five-year moving average recorded during the 

reporting period. • The projected five-year moving average predicts an increase in fatalities for the 

period for which this target will be set. • TARGET: Based on the recent and projected increases in 

fatalities, Connecticut chooses to set a target to maintain the five-year moving average of 277. The 

target in the SHSP for this performance metric is combined with the number of serious injuries. If we 

meet this target, or fall below it, the goal for the combined performance measure in the 2017-2021 

SHSP will be achieved.

Number of Serious Injuries:1547.0

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

• There were 1,643 Serious (A) Injuries in 2017, a single year decrease from the 1,689 recorded in 

2016. • The 2017 five-year moving average of 1,547 Serious (A) Injuries in 2017 also decreased from 

the 1,574 recorded in 2016. • The most current preliminary data show there were 1,269 Serious (A) 

Injuries in 2018, a single year decrease from the 1,643 recorded in 2017. The 2018 Serious (A) Injury 

total could be an anomaly, based on recent single year totals and trends. It is the lowest single year 

value recorded during the reporting period. The 2018 five-year moving average value of 1,497 also 

represents a decrease from the previous year and is the lowest recorded during the reporting period. 

• The projected five-year moving average projects a decrease in Serious (A) Injuries for the period for 

which this target will be set. • TARGET: Although there have been recent decreases in Serious (A) 

injuries, the preliminary 2018 figure and projected moving average may be an anomaly. Based on 

current data, Connecticut chooses to set a target to maintain the five-year moving average of 1,547 

Serious (A) Injuries. The target in the SHSP for this performance metric is combined with the number 

of fatalities. If we meet this target, or fall below it, the goal for the combined performance measure in 

the 2017-2021 SHSP will be achieved.

Fatality Rate:0.883

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

• There were 0.883 Fatalities per 100M VMT in 2017, a single year decrease from the 0.961 recorded 

in 2016. • Although the single year fatality rate decreased, the five-year average continued to rise to 

0.883 in 2017. • The most current preliminary data show the fatality rate of .930 for 2018, a single 

year increase from the .883 recorded in 2017. The 2018 five-year moving average value of 0.885 also 

represents an increase from the previous year. This figure is also the highest five-year moving 
2019 Connecticut Highway Safety Improvement Program

Page 29 of 41

average recorded during the reporting period. These rate projections are based on 2017 VMT data. • 

The projected five-year moving average predicts an increase in the fatality rate per 100M VMT for the 

period for which this target will be set. • TARGET: Based on the recent and projected increases in 

fatalities, Connecticut chooses to set a target to maintain the five-year moving average of .883 

Fatalities per 100M VMT. The 2017-2021 SHSP does not use rates as a performance metric.

Serious Injury Rate:4.931

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

• There were 5.216 Serious (A) Injuries per 100M VMT in 2017, a single year decrease from the rate 

of 5.338 recorded in 2016. • The 2017 five-year moving average of 4.931 Serious (A) Injuries per 

100M VMT in 2017 also decreased from the 5.025 recorded in 2016. • The most current preliminary 

data show a rate of 4.029 Serious (A) Injuries per 100 M VMT in 2018, a single year decrease from 

the 5.216 recorded in 2017. The 2018 Serious (A) Injury total and rate could be an anomaly, based

on recent single year totals and trends. It is the lowest single year rate recorded during the reporting 

period. The 2018 five-year moving average value of 4.752 also represents a decrease from the 

previous year and is the lowest recorded during the reporting period. • The projected five-year moving 

average projects a decrease in Serious (A) Injuries for the period for which this target will be set. • 

TARGET: Although there have been recent decreases in Serious (A) injuries, the preliminary 2018 

figure and projected moving average may be an anomaly. Based on current data, Connecticut 

chooses to set a target to maintain the five-year moving average of 4.931 Serious (A) Injuries per 

100M VMT. The 2017-2021 SHSP does not use rates as a performance metric.

Total Number of Non-Motorized Fatalities and Serious Injuries:307.2

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

• There were 345 Fatalities and Serious (A) Injuries in 2017, a single year decrease from 365 

recorded in 2016. • The 2017 five-year moving average of 307.2 Fatalities and Serious (A) Injuries in 

2017 increased from the 294.4 average number in 2016. • The most current preliminary data show 

283 Fatalities and Serious (A) Injuries in 2018, a single year decrease from the 345 recorded in 2017. 

The 2018 five-year moving average value of 310.6 represents an increase from the previous year. 

This figure is also the highest five-year moving average recorded during the reporting period. • The 

projected five-year moving average for 2013-2017 predicts an increase in Fatalities and Serious (A) 

Injuries for the period for which this target will be set. • TARGET: Based on the trend line, the fiveyear moving average of non-motorist fatalities and serious (A) injuries is expected to remain relatively 

the same or increase slightly. The new target is proposed to maintain the current five-year moving 

average of 307.2 Fatalities and Serious (A) Injuries for the 2020 HSP planning period. If we meet this 

target, or fall below it, the goal in the 2017-2021 SHSP will be achieved.

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

safety performance targets. 

Internal coordination between HSO and Traffic Engineering began in the spring of 2019. The HSO's contractor 

prepared initial targets for each of the safety performance targets for discussion. Once the draft targets were 

approved at the staff level, they were forwarded to CTDOT management for discussion and approval. After the 

targets were approved, CTDOT hosted a meeting with the MPOs to discuss safety performance targets. During 

the June 4, 2019 meeting, there was a presentation and discussion on Federal reporting requirements, 

deadlines, and an assessment on past and current trends. Following the meeting, CTDOT sent a letter to all 
2019 Connecticut Highway Safety Improvement Program

Page 30 of 41

the MPOs requesting a resolution from their policy board no later than 2/27/2020 stating that they either 

support CTDOT's targets or that they plan to set their own. At the time this report was prepared, CTDOT has 

not received any resolutions.

Does the State want to report additional optional targets? 

No

Evaluation

Program Effectiveness

How does the State measure effectiveness of the HSIP? 

• Change in fatalities and serious injuries

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

the State's program level evaluations. 

•

Since the number of fatalities and serious injuries trends have not changed much since last year, it is 

difficult to evaluate the State's HSIP program. CT finalized its SHSP in July 2017 and it is anticipated 

that many of the infrastructure related strategies will be implemented resulting in fewer fatalities and 

serious injuries. 

• A safety effectiveness evaluation module is planned for the CT Roadway Safety Management System 

(CRSMS) which will allow users to evaluate a individual project(s). Features such as lives saved and 

injuries prevented are being considered to help inform decision makers of the return on past 

investments and help make a case for future funding. 

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

For 2014-2017, FARS was used for the number of fatalities for all SHSP emphasis areas except for 

young drivers. All other crash data is from the UCONN crash data repository. 

• The HMVMT data source for 2010-2017 is FARS. 2018 data is not available so 2017 was used. 

• In some cases, data was updated from previous years in order to reflect the most up-to-date
