Abstract

The invention discloses a ferry collision risk assessment method, system and device, and a medium. The method comprises the following steps of: determining an enclosed region through setting a water region boundary coordinate, acquiring AIS data in the enclosed region, carrying out the preprocessing of the AIS data, and acquiring the ship information; constructing an original trajectory of the ship according to the ship information, and segmenting the original trajectory; according to the spatial and temporal distribution of the original tracks of a ferry and target ships, acquiring target ships possibly meeting the ferry in the voyage, calculating relative motion parameters of the ferry and each target ship, and identifying meeting ships in the ferry and the target ships; and according to the trajectory data of the ferry and the corresponding meeting ships, constructing a multi-ship meeting scene in the ferry crossing process, and according to the multi-ship meeting scene, evaluating the ferry collision risk. According to the ferry collision risk assessment method, the multi-ship meeting scene in the ferry crossing process is constructed, the high-risk region in the ferry water region is recognized, and support is provided for guaranteeing the sailing safety of the ferry. The ferry collision risk assessment method, the system and the device can be widely applied to the field of water transportation safety and risk assessment.

Description

technical field [0001] The invention relates to the field of water transport safety and risk assessment, and in particular to a ferry collision risk assessment method, system, device and medium. Background technique [0002] Water transportation has the characteristics of low cost and large volume, and plays an important role in transportation, but it also has the risk of water traffic accidents. Ship collision is a typical water traffic accident, which usually causes serious consequences. The assessment of collision risk can provide strong support for ensuring water traffic safety. Existing collision risk assessment methods can be divided into microscopic and macroscopic methods. The macroscopic method is mainly based on historical accident data and traffic flow data, and mainly considers the overall characteristics of ship traffic flow, analyzes the probability of collision, and identifies the cause and risk level of collision accidents. The microscopic approach is mainl...
