Fuss & O’Neill performed professional services for the State of Connecticut Department of Transportation (CTDOT) for the development of systematic countermeasures to reduce the instances of roadway departure crashes along horizontal curves on state-owned and maintained roads and ramps throughout District 1.

This is to reduce the number of fatal and serious injury crashes on curves – approximately 825 curves were identified by CTDOT that would benefit from enhances signing. Electronic field data collection methods were developed and employed to accurately locate, update attributes, and catalog photos of road-curve signs and related assets. Data was uploaded in real time to our GIS database server and visualized in our customized project dashboard where information was QC’d and adopted to the planning environment.

Fuss & O’Neill conducted a field review of each curve, which includes reviewing the existing conditions using a ball-bank indicator and GIS mapping to determine appropriate advisory speeds. Construction plans were also developed for installing warning signs and advisory ramp speeds signs at the locations.
