65 A P P E N D I X D9 In an attempt to estimate the capacity of the inland waterway system on a link-by-link basis, we developed a process using monthly historical traffic and delay data to estimate the delay as a function of traffic and then to define a capacity for each lock. The process was designed to be easily replicated across all of the locks in the system using a small dataset and limited computation.

66 We approached the development of delay curves (the functional relationship between traffic level and delay) on two parallel tracks: a queuing model and a regression model.

67 for each lock into its transit equation and solving for the TowPerDay variable, we were able to generate an estimate of the capacity in terms of annual traffic. Comparing the capacity traffic and the current traffic provides a first level check of the estimates.
