TADI performed traffic counts, travel time studies,  traffic analysis of the existing conditions, and analysis of optimized traffic signal timing for 13 signalized intersections along this major corridor through the City of Fond du Lac.  The optimized timings are designed to improve traffic signal coordination/progression along STH 23 and take into account current MUTCD timing guidelines.  TADI coordinated the implementation of the new timings and helped fine-tune the timings with staff in the field to maximize efficiency.  Post-implementation travel time and delay runs indicate up to a 42-percent reduction in arterial delay and up to a 43-percent reduction in stops.  Additionally, the project investigated an off-set left-turn issue at the STH 23 intersection with Main Street.  TADI worked with staff on a solution that improved operations and safety at the intersection.
