Jeffrey W Buckholz, PhD, P.E., PTOE Buckholz Traffic

Jacksonville, Florida
Traffic Engineering, Construction Defects - Traffic Signal, Trucks, Pedestrians, Crash, Traffic Accident, Work Zone, Roadway, Sight Distance
I have 44 years of hands-on technical experience in the traffic engineering field, running my own consulting firm for 34 of those years. I am a recognized national expert in traffic signal operation, timing, design, and construction and am also very proficient in pavement marking design, roadway signing, and work zone traffic control. However, I am not an accident reconstruction expert. I have participated in over 260 cases nationwide with many of these cases involving deposition and mediation testimony and a number of these cases going all the way to trial. I have given both live and videotaped testimony and have testified for both the plaintiff and the defense. It should be emphasized that I am a practicing engineer and that my expert testimony work constitutes only a portion of my engineering practice.
