FDOT Innovative Operational Safety Improvements Research

Kittelson & Associates, Inc. (KAI) conducted an evaluation of Innovative Operational Safety Improvements at Unsignalized Intersections. The research project was primarily focused on identifying innovative treatments to improve safety on at-grade stop controlled intersections along higher speed, multilane arterials. An initial crash evaluation, conducted as part of this research, examined a sampling of unsignalized intersections to identify prevalent crash types and needed improvements. The product of the research effort is a guidebook of innovative treatments to assist designers in identifying measures that can be implemented at locations were traditional improvements have proven ineffective.
