Executive Summary

The reporting period for 2013 is October 1, 2011 to September 30, 2012.

ConnDOT has obligated more systematic improvements in the HSIP program this reporting 

period as compared to previous years. While ConnDOT's traditional site analysis approach 

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

at specific locations, the systemic approach leads to widespread implementation of projects to 

reduce the potential for severe crashes, whether or not crashes have occurred at any given site. 

Because many of CT's fatal and severe injury crashes are spread out, the systematic approach 

provides an alternative method to identify and implement low-cost safety countermeasures 

addressing specific risk factors across the transportation network. Systematic analysis is a 

complement to site-specific analysis, and can be very effective in implementing low-cost safety 

countermeasures. As Connecticut prepares to update its SHSP to be compliant with MAP-21 

requirements, it is likely that additional emphasis will be placed on systematic 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.

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 accidents 

effective with 2007 accidents and complete local road accident information is now available 
2013 Connecticut Highway Safety Improvement Program

through June 2011. Property damage only crashes from July 2011 forward has not been coded 

to order to help reduce the backlog of crash records for the entire State. Since traffic volume 

data for the majority of local roads is not available, an analytical analysis of crashes on nonstate maintained roadways to determine project selection has not been possible. Therefore, 

the Department annually solicits the Regional Planning Organizations (RPO) 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.

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 appear to have an unusually high 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 described 

in the preceding paragraph. 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-offthe-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.

Project 170-3055 is a low-cost systematic approach to reduce the number of fatal and severe 

injuries on rural major collector state-maintained roadways that exceed the accident severity 

rate. Recent research based on data collected from Connecticut and Washington (Publication 
2013 Connecticut Highway Safety Improvement Program

10

No. FHWA-HRT-10-019) indicates that improved curve delineation has the potential to reduce 

crashes and crash severity on rural roads particularly at sharp horizontal curves where the 

radius is less than 492 feet (11.65 degrees). The research for Connecticut indicated significant 

crash reductions; 25 percent reduction for injury & fatal accidents and over 34 percent 

reduction in lane departure accidents (dark conditions). Further, an economic analysis revealed 

that improving curve delineation with signing improvements is a very cost-effective treatment 

with the benefit-cost ratio exceeding 8:1. The Department is implementing a project to 

systematically sign horizontal curves located on just those rural major collector roadways 

where the actual accident rate for fatal and severe injuries exceeds the average rate for this 

roadway classification. Based on the anticipated success of this project, other systematic 

improvement projects are being explored.

The source of the data for functional classification is FARS (2012 data is not available). FARS does not have data on the number of 

serious injuries. CT's crash file does not include functional classification, therefore, data on number of serious injuries, fatality rate 

and serious injury rate (per HMVMT) is not available.

The file only distinguishes between State-owned and Town-owned roadways.

The source of the data for roadway ownership is from the State's crash file. Data is not available to compute fatality and serious 

Injury Rate (per HMVMT) based on roadway ownership.

For those fields where data is available, the data is annual NOT rolling averages.

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. 

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.
