Tow delay is an important component of cost at navigation locks, and delay reduction is a major benefit of lock improvement. Computer simulation is a valuable method of estimating lock delay under a variety of existing and future proposed conditions. However, a single simulation run, which can be quite costly in terms of both computer and analyst time, produces a delay estimate for only one traffic level under one set of conditions. This paper describes methods which can be used to estimate an entire delay vs. traffic curve from a limited amount of simulation data. Estimation techniques appropriate for various amounts of data are derived, and factors affecting the accuracy of the delay estimates are discussed. Applications of these methods to inland waterway planning projects are given.
