State planning curve warning signs in SW Conn. roads

In an effort to reduce fatal and serious injury crashes on curves, the Department of Transportation is proposing to install warning signs on state roads in southwest Connecticut.

Current plans call for the signs to be in Stamford on Interstate 95, Route 104 and Route 137.

It plans to hold a public hearing on the “horizontal curve warning signs” at 7 p.m. Nov. 13 at the Stamford Government Center, Safety Training Conference Room, 888 Washington Blvd.

The project “will systemically install/upgrade horizontal alignment signs on all state-owned roads in southwestern Connecticut,” DOT said in a release.

“The project will also be removing any horizontal alignment signs on curves where signs are no longer warranted. The purpose of this project reduce the number of fatal and serious injury crashes on curves located on stated-owned roads.”

Construction is anticipated to begin next fall, assuming availability of funding. The estimated construction/installation cost for the southwestern region of the state is $2,075,000 and will use federal funds.

According to the Federal Highway Administration,“horizontal alignment signs, informally called curve warning signs, can improve safety by alerting drivers to changes in roadway geometry that may not be apparent or expected. These signs provide visual information for the driver about the nature of the curve they are approaching, letting them know whether it's a gradual curve, a sharp turn, a hairpin turn, or some combination.”

The Institute of Transporation at the University of Iowa said a study found the installation of curve warning signs and chevrons at 228 locations in Connecticut and Washington produced an 18 percent reduction in injury and fatal crashes, 27.5 percent reduction in nighttime crashes, and 25 percent reduction in nighttime lane-departure crashes.
