Connecticut 2006 Five Percent Report
This report is in response to the Federal requirement that each state describe at least 5 percent of its locations currently exhibiting the most severe highway safety needs, in accordance with Sections 148(c)(1)(D) and 148(g)(3)(A), of Title 23, United States Code. Each state’s report is to include potential remedies to the hazardous locations identified; estimated costs of the remedies; and impediments to implementation of the remedies other than costs. The reports included on this Web site represent a variety of methods utilized and various degrees of road coverage. Therefore, this report cannot be compared with the other reports included on this Web site.
Protection from Discovery and Admission into Evidence—Under 23 U.S.C. 148(g)(4) information collected or compiled for any purpose directly relating to this report shall not be subject to discovery or admitted into evidence in a Federal or State court proceeding or considered for other purposes in any action for damages arising from any occurrence at a location identified or addressed in the reports. |

CONNECTICUT DEPARTMENT OF TRANSPORTATION
ANNUAL SAFETY REPORT
2005 - 2006
5 Percent Report
Background
SAFETEA-LU
created a new Highway Safety Improvement Program (HSIP) as a "core" FHWA
program with separate funding, replacing the Hazard Elimination Program,
effective October 1, 2005. The purpose of the HSIP is to reduce traffic
fatalities and serious injuries on public roads. As part of the new HSIP,
States are required to submit an Annual Report describing not less than 5
percent of their highway locations exhibiting the most severe safety needs.
The intent of this provision is to raise public awareness of the highway safety
needs and challenges in the states. It is the intention of the FHWA to make
each state "5 Percent Report" available to the public on a USDOT Web site.
Procedure Used to Develop the 5 Percent List
Identification
and surveillance of locations displaying a higher than expected accidents rate
on the highway system are accomplished primarily through a computerized
surveillance system (SLOSSS) utilizing traffic record files maintained by the
Department's Planning Data and Inventory Section (PDI). These files consist
of: a crash record file; an average daily traffic file; a roadway
characteristic inventory file. 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 unsignalized drive) or expressway interchange, and further by number
of lanes and control of access. The basic search of the accident file to identify
locations that may have an abnormal crash history can take many forms. In the
case of this year's 5 Percent Report, the entire State highway system is
surveyed based upon fatal and injury accidents occurring during the latest
available period. A computer program utilizing the previously mentioned data
files is run with average accident rates computed. Based upon these average
values, a threshold of abnormally high rates is developed. Locations with
rates equaling or exceeding the threshold value appear on the list.
The
list generated for the three year time period covering January 1, 2002 to
December 31, 2004 yielded two-hundred ninety eight (298) locations. The top
five percent of these locations are described in sequential order in the table
following this narrative.
It
is recognized that Connecticut's five percent list considers all reported
injuries and does not include local roads. In accordance with FHWA guidance,
it is anticipated that by August 31, 2009, improvements to Connecticut's accident
data system will permit future 5 Percent Reports to include local roads and to
focus on serious (Type A) injuries.
