Human Factors Evaluation of Electronic Chart Display and Information Systems(ECDIS)

摘要

This report describes a study done to examine the contributions that ECDlS mightmake to the operational practices on the commercial bridge. Issues examined were: the contribution to the safety of navigation, the effect on the navigational workload, the features required during route monitoring, and the potential contribution of integration with radar. Two commercially-available ECDlS devices were installed on the simulator bridge at MSl/CAORF. Expert mariners made repeated port arrivals and departures. A variety of ship and mariner performance measures were collected and extensive debriefings were conducted. EODlS demonstrated the potential to increase safety, primarily by decreasing the cross track distance from a planned track, and the potential to decrease the workload of route monitoring, primarily by replacing time-consuming plotting on the paper chart. For route monitoring, mariners required only a simple display outlining safe water, but recommended access to a larger set of chart features as reference. Radar integration, as implemented on the devices used, did not provide the ARPA information mariners required.
