Abstract:This Concept of Operations (ConOps) is the final installment in a series of three reports focused on identifying opportunities for the application of Intelligent Transportation System (ITS) technology—or equivalent—within the maritime transportation environment of
the St. Lawrence Seaway and Great Lakes. The ConOps presented in this paper proposes a computer-based application that will improve the current level of accuracy of estimated times of arrival (ETAs) for vessels operating on the Seaway, and enhance overall system efficiency and situational awareness of Seaway operators and vessels. The proposed application, called SeaTA (for Seaway Time of Arrival) collects real-time operational data (e.g., course, speed, status) from vessels using existing, shipboard Automated Information System (AIS) transceivers, and uses that data to derives ETAs from each vessel’s current position to various critical waypoints along their planned routes (e.g., locks, bridges, or navigational hazards). The proposed application is intended to improve overall safety and efficiency of the Seaway, reduce operating costs of vessels and Seaway infrastructure, and yield concurrent efficiencies to the region’s heavily-traveled road and rail network.
