The requirements for a navigation guidance system which will effect an increase in the ship processing capacity of the Saint Lawrence Seaway (Lake Ontario to Montreal, Quebec) are developed. The requirements include a specification of system positioning accuracy and the type and frequency of information which must be displayed to the master of each ship in the Seaway. A detailed development of the logic used to compute Seaway capacity as a function of the guidance system positioning accuracy is presented. A computer program is given which follows this logic and is used to compute Seaway capacity as a function of positioning accuracy for two classes of ships. Various sensitivity analyses are presented. It is shown that the capacity of the Seaway could be increased by up to 30 percent through the use of a navigation guidance system.
