INSTRUCTOR:

Robert K. Seyfried, P.E., PTOE, FITE, RK Seyfried and Associates, Evanston, IL, USA

Robert was the former Director of the Transportation Safety of the Northwestern University Center for Public Safety in Evanston, Illinois. He was responsible for the administration, planning, development and presentation of seminars and workshops in transportation engineering, both on-campus and throughout the United States. A graduate of Northwestern University, he is a Fellow of the Institute of Transportation Engineers and a member of the American Society of Civil Engineers, Transportation Research Board and the Regulatory/Warning Signs Technical Committee of the National Committee on Uniform Traffic Control Devices. Seyfried has a total of 36 years experience in transportation engineering and was on the staff of the Northwestern University Center for Public Safety for 32 years. Seyfried is the primary author of the ITE Professional Traffic Operations Engineers Certification Program Refresher Course manual and the upcoming ITE Traffic Operations Practitioner Specialist (TOPS) Certification Program Refresher Course and Traffic Signal Operations Specialist (TSOS) Certification Program Refresher Course manual.
