A basic understanding of traffic flow is essential for addressing many traffic engineering issues, including signal timing, capacity analysis, and incident management. This course describes the basic elements of the traffic system, along with the influences of each. The course also presents various approaches to modeling and analyzing traffic flow. Upon completion of the course, the attendee will be able to:

  • characterize elements of the traffic system
  • define key traffic stream parameters
  • express theoretical relationships between
  • traffic stream parameters
  • describe types of traffic flow
  • define measures of performance for highway operations
  • summarize basic studies to evaluate traffic stream performance


This course is intended for managers, engineers, and technicians involved with traffic operations. Basic math skills are required.


Airton G. Kohls, Ph.D.
Dr. Kohls is a Research Associate at the University of Tennessee's Center for Transportation Research. He holds a B.S., M.S. and a Ph.D. degree in Civil Engineering from the University of Tennessee. He has twelve years of practical experience in Traffic Engineering with both public and private agencies.

This course is one of six courses that form the core requirement for the Tennessee Academy for Transportation Engineering (TATE) certificate. TATE provides continuing education for engineers, planners, designers and technicians. The program focuses on the basic design of transportation facilities, the evaluation of traffic operations, and the collection of data to support various transportation studies. Successful completion of the required curricula of core and elective courses, confers TATE certification. For more information, contact Airton Kohls at 865-974-5255.
