What We Do
The Connecticut Department of Transportation’s Safety Engineering Unit’s highest priority is the prevention of fatal and serious injury crashes involving all road users on state and local roadways in Connecticut. It's part of everything we do, and the reason why you may notice new types of roadway configurations, signals, signs, and pavement markings being put into service in Connecticut. Our engineers are constantly searching for new and innovative solutions proven to save lives and reduce serious injuries through the implementation of Connecticut's Strategic Highway Safety Plan and the Highway Safety Improvement Program.
Safety Engineering also develops transportation policies, standards, guidelines, and practices related to highway safety, and advocates the use and implementation of the Highway Safety Manual. We also help build and strengthen relationships between State and Local officials to help prevent and resolve roadway safety issues on all public roads in Connecticut.

High Friction Surface Treatment (HFST)
A High Friction Surface Treatment (HFST) applies a highly durable aggregate to the pavement using a strong polymer binder to restore or maintain pavement friction.
Rectangular Rapid Flash Beacons (RRFB)
Rectangular Rapid Flash Beacons (RRFB) can enhance safety by reducing crashes between vehicles and pedestrians at uncontrolled approaches to unsignalized intersections and mid-block pedestrian crossings by increasing driver awareness of potential pedestrian conflicts.
