ABSTRACT: In this paper the author depicts new approach involving fuzziness in navigational situation assessment. Nowadays operator at maritime traffic monitoring station is assumed to have access to a great amount of data. The data comes from different places and multiple of sensors. Properly associated data enable the operator to approximate congestion for each restricted and considered as vital regions. Ship's presence function within a confined area defines a non-empty bounded closed interval. It can be denoted by the earliest and latest bounds of the closed time interval at a given possibility level. To assess situation within any confined region one should calculate maximal sum of safety factors present within forecast imprecise slots of time. Safety factors themselves are also fuzzy, imprecise values.
