Maritime traffic route is the basis for the analysis of ship traffic characteristics and navigation safety. However, the spatial freedom of ship navigation makes the extraction of maritime traffic route a challenging task. In order to realize the extraction of ship traffic routes at sea, a maritime route extraction method based on ship history automatic identification system (AIS) data is proposed. In this method, the ship trajectory with rich position information is transformed into a ship trip semantic object (STSO) with semantic information, and each ship trip is abstracted as a "stop-waypoint-stop" trip object. In addition, based on the graph theory, the STSO is further integrated into the nodes and edges of a directed maritime traffic graph to realize the extraction and expression of the shipping routes. In order to prove the effectiveness of this method, the real-world AIS historical data are used for testing, and the results show that this method can effectively extract maritime traffic routes.
