Evaluation of intersection-delay measurement techniques. Paper presented at the 52nd Annual Meeting of the Highway Research Board HRB, Washington, D.C., January 1973.

Evaluation of two techniques for measuring intersection delay is given. Delay measurements taken from videotapes for each of the methods were compared with delays computed from time-lapse photographs made concurrently with the video-tapes. Neither method produced consistent trends in predicting delays as compares to the base methods, and even these failed to give consistent, direct relations.
