Executive Summary

The reporting period for 2016 is from October 1, 2014 to September 30, 2015.

The HSIP is administrated and managed by the Safety Engineering Section located within the Division of 

Traffic Engineering, Bureau of Engineering and Construction.

This reporting period, CTDOT has obligated more systemic and systematic safety improvements in the 

HSIP program compared to past reporting periods. While CTDOT's traditional site analysis approach, 

known as the suggested List of Surveillance Study Sites (SLOSSS), results in safety investments at specific 

locations, the systemic and systematic approach leads to widespread implementation of projects to 

reduce the potential for fatalities and/or serious injuries, whether or not crashes have occurred at any 

given site. Because many of CT's fatal and serious injury crashes are spread out across all public roads, 

the systematic/systemic approach provides an alternate method to identify and implement low-cost 

safety countermeasure addressing specific risk factors across the entire roadway network.

Systematic/systemic analysis is a compliment to site-specific analysis, and can be very effective in 

implementing low-cost safety improvements.

CT is currently updating its SHSP and it is likely that additional emphasis will be placed on systematic and 

systemic improvements.

Below are notes that explain why data has not been entered for specific questions:

Q25: CTDOT crash record database does not have the capability to query for serious injuries based on 

functional classification

Q32: CT is in the process of updating its SHSP and some of the emphasis areas will be changing. The 

data shown for this question includes some existing and proposed emphasis areas. Overall each 

emphasis area has remained the same or trending downward for each of the four performance 

measures.

Q33 & Q34: CTDOT crash record database does not have the capability to query on targeted crash types 

for the selected systemic improvements

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 MAP-21 Reporting Guidance dated February 13, 2013 and consists 

of four sections: program structure, progress in implementing HSIP projects, 

progress in achieving safety performance targets, and assessment of the 

effectiveness of the improvements. 

Program Structure

Program Administration

How are Highway Safety Improvement Program funds allocated in a State? 

Central

Describe how local roads are addressed as part of Highway Safety Improvement Program.

Local Roads are addressed by the Local Road Accident Reduction Program (LRARP). The LRARP 

provides federal funding for safety-related improvements not on the state-numbered highway system, to 

address hazardous elements identified at specific locations and along roadway sections. The Crash Data 

and Analysis Office commenced coding all local road crashes data in 2007 and complete local road crash 

information is now available at the crash repository at the UCONN. Since traffic volume data for the 

majority of local roads is not available, an analytical analysis of crashes on non-state maintained 

roadways to determine project selection has not been possible. Therefore, the Department annually 

solicits the nine Council of Governments (COGs) in CT for recommended improvements on behalf of 

their member towns, to address identified hazardous elements. These improvements may include signal 

enhancements, minor geometric improvements, roadside obstacles, sight line conditions, hazards to 

pedestrians and poor or unmarked roadways. In the future when more local road data is available, the 

methodology for selection of improvements under the LRARP will be reevaluated. In the interim, the 

Department has expanded the Local Road Program in order to consider system-wide improvement 

projects designed to address run-off-road fixed-object collisions on local roads. The project cost eligible 

for federal participation is currently capped at $500,000 per location. All locations are reviewed and 

investigated by the Division of Traffic Engineering and the Division of Highway Design.

Briefly describe coordination with internal partners. 

Responsibility for carrying out the administration of the HSIP within the Department is assigned to the 

Division of Traffic Engineering and the Bureau of Policy and Planning-Crash Data and Analysis Section. 

The Department actively collects and compiles crash data with the intent of addressing problematic 

conditions that are identified. Identification and surveillance of locations displaying higher than 

expected accident rates on the state highway system are accomplished primarily through a 

computerized surveillance system utilizing traffic record files maintained by the Bureau of Policy and 

Planning. Those files consist of (1) a crash record file, (2) an average daily traffic file, (3) an inventory of 

certain roadway characteristics. The inventory file identifies locations as being either rural or urban, as 

either a section of highway, section of expressway, intersection with another state highway, intersection 

with a town road (or signalized drive) or expressway interchange and further by number of lanes and 

control of access. Some groups having few locations are merged with similar groups. The Bureau of 

Policy and Planning runs a computer program utilizing the three files described above. The results are 

lists of locations that have a higher than expected crash rate. These lists are referred to as SLOSSS lists 

(Suggested List of Surveillance Study Sites). In that computer program, average crash rates and number 

of crashes are computed for the various groups of locations. Based upon those average values, a 

threshold of abnormally high numbers and rates is developed for each location. Locations equaling or 

exceeding the threshold are reviewed. The thresholds are changed occasionally based upon prior 

experience with these lists. The process described above is not intended to be the sole determinant in 

identifying locations having problematic characteristics. Many locations with crash rates not abnormally 

high will demonstrate crash type or severity patterns symptomatic of the problematic characteristic for 

a particular location. An example would be a pattern of run-off-the-road crashes at a curve. Some other 

locations may have design characteristics similar to a design characteristic determined to be problematic 

(e.g., rigid sign posts, poor sight line). These may also be considered for safety improvement.

CTDOT is considering a major change to the Local Road Accident Reduction Program (LRARP). Each of 

the 9 council of governments (COG's) in the State will be encouraged to prepare a regional 

transportation safety plan to identify the region's critical safety needs and guide investment decisions to 

reduce fatalities and serious injuries on secondary roads for all road users, while promoting safe travel 

for all modes. These plans would also be used to generate candidate HSIP projects.

Describe any other aspects of the overall Highway Safety Improvement Program effectiveness on 

which you would like to elaborate. 

HSIP funding has helped CT see a decreasing trend in some crash types over the last few years, just not 

fatalities and serious injuries. With sustained funding associated with the FAST ACT and a new SHSP, CT 

hopes to meet or exceed its overall safety goals of reducing the number of fatalities and serious injuries 

on all public roads.

Glossary

5 year rolling average means the average of five individual, consecutive annual points of data (e.g. 

annual fatality rate).

Emphasis area means a highway safety priority in a State’s SHSP, identified through a data-driven, 

collaborative process. 

Highway safety improvement project means strategies, activities and projects on a public road that are 

consistent with a State strategic highway safety plan and corrects or improves a hazardous road location 

or feature or addresses a highway safety problem. 

HMVMT means hundred million vehicle miles traveled.

Non-infrastructure projects are projects that do not result in construction. Examples of noninfrastructure projects include road safety audits, transportation safety planning activities, 

improvements in the collection and analysis of data, education and outreach, and enforcement 

activities.

Older driver special rule applies if traffic fatalities and serious injuries per capita for drivers and 

pedestrians over the age of 65 in a State increases during the most recent 2-year period for which data 

are available, as defined in the Older Driver and Pedestrian Special Rule Interim Guidance dated 

February 13, 2013. 

Performance measure means indicators that enable decision-makers and other stakeholders to monitor 

changes in system condition and performance against established visions, goals, and objectives.

Programmed funds mean those funds that have been programmed in the Statewide Transportation 

Improvement Program (STIP) to be expended on highway safety improvement projects.

Roadway Functional Classification means the process by which streets and highways are grouped into 

classes, or systems, according to the character of service they are intended to provide.

Strategic Highway Safety Plan (SHSP) means a comprehensive, multi-disciplinary plan, based on safety 

data developed by a State Department of Transportation in accordance with 23 U.S.C. 148. 

Systematic refers to an approach where an agency deploys countermeasures at all locations across a 

system.

Systemic safety improvement means an improvement that is widely implemented based on high risk 

roadway features that are correlated with specific severe crash types. 

Transfer means, in accordance with provisions of 23 U.S.C. 126, a State may transfer from an 

apportionment under section 104(b) not to exceed 50 percent of the amount apportioned for the fiscal 

year to any other apportionment of the State under that section.
