EFFECTIVENESS OF THREE ELECTRONIC SYSTEMS AS COLLISON AVOIDANCE AND GROUNDING AVOIDANCE AIDS; A SIMULATOR INVESTIGATION IN A CONGESTED HARBOR APPROACH

This is the executive summary of a report which describes an experiment conducted at CAORF to examine shipmasters' collision-avoidance and grounding-avoidance performance in congested harbor approach situations. Comparisons were made between test subjects operating with radar, with a collision avoidance system (CAS system), and with a collision avoidance system with navigation option (CAS + NAV system in which channel boundaries and shoal lines are displayed with synthetic radar and collision predictive information). The results indicate that the test subjects who operated with the CAS + NAV system had fewer serious incidents (collisions, near misses, groundings) than members of the other groups. Analysis showed that the improved safety of the CAS + NAV group resulted from their earlier tracking of threats and their ability to make much larger maneuvers to avert a collision. Although the larger maneuvers brought CAS + NAV subjets closer to shoals, the displayed information on shoal locations enabled them to maintain safe clearance with consistency.
