Abstract. The share of human factor in the occurrence of navigation accidents represents a high proportion of the total accident rate. Elimination of the human factor responsible for the occurrence of navigational accidents would contribute to the overall safety of navigation on inland waterways. The main causes of human-induced navigation accidents include inattention, fatigue or poor concentration on vessel control. The design of the system for increasing navigation safety consists of a system for monitoring the life functions of a crew member as well as a position of the vessel towards the fairway / shore. The first level focuses on tracking the life function of the vessel's crew / boat master. The second level addresses the position of the vessel and the possibility of increasing safety by cooperating with the data provided by Automatic Identification System -AIS. The proposal of the system represents interconnection of both levels and brings high degree of control of the vessel in extraordinary situations.
