ACCURACY OF DELAY SURVEYS AT SIGNALIZED INTERSECTIONS

Delay is an excellent tool for evaluating the operation of signalized intersections. However, it is not easily determined. This paper examines two approaches for measuring delay--a time-space diagram and a queuing diagram--and explains various problems related to each. The paper concludes that, while delay cannot be precisely measured, it can be a useful engineering tool if it is calculated properly.
