Researchers are tackling maritime situational awareness challenges on multiple fronts. This traffic graph and density map, extracted from automated identification system data of ship routes in the Ionian Sea, aids in establishing a baseline for maritime traffic analysis and prediction.

Mariners can obtain situational awareness of surface maritime traffic by looking out to sea and by using devices such as radars and automated identification system transponders on ships. These systems can identify vessels along with pertinent data about their voyage. But these methods have limitations. Master mariners with powerful binoculars can tell a lot just by looking at a ship far off in the distance; however, they can’t see beyond the horizon, in bad weather or at night. The horizon even limits radar and transponder data can be manipulated or deleted.
