Approximately 50% of marine accidents in Japan involve pleasure boats (PBs), small ships used for marine leisure. Previous studies have primarily analyzed the causes and trends of marine accidents involving larger vessels. Effective maritime safety management requires predicting future accidents and identifying conditions that contribute to these incidents. This study developed a predictive model using Light Gradient Boosting Machine to estimate the monthly probability of PB marine accidents in the central part of the Seto Inland Sea, Japan's highest incidence area. The model utilized 2986 PB marine accidents (2005–2021), sea area characteristics, vessel traffic density, and weather conditions to learn patterns of marine accident occurrence for each approximately 10 nautical mile square. The prediction accuracy indicated that the results generally aligned with the actual incident rates. Additionally, the Shapley Additive exPlanation, an interpretation method for artificial intelligence models, reveals that in areas with a high predicted probability, the number of islands and vessel traffic density were the main crucial factors. The results of this study can effectively aid port authorities and rescue organizations in optimizing the season and area selection for safety activities and rescue vessel deployment.","subitem_description_language":"en","subitem_description_type":"Abstract"}]},"item_1617186643794":{"attribute_name":"Publisher","attribute_value_mlt":[{"subitem_publisher":"Elsevier","subitem_publisher_language":"en"}]},"item_1617186660861":{"attribute_name":"Date","attribute_value_mlt":[{"subitem_date_issued_datetime":"2027-02-05","subitem_date_issued_type":"Available"}]},"item_1617186702042":{"attribute_name":"Language","attribute_value_mlt":[{"subitem_language":"eng"}]},"item_1617187056579":{"attribute_name":"Bibliographic Information","attribute_value_mlt":[{"bibliographicIssueDates":{"bibliographicIssueDate":"2025-02-05","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"322","bibliographicNumberOfPages":"25","bibliographicPageStart":"120460","bibliographic_titles":[{"bibliographic_title":"Ocean Engineering","bibliographic_titleLang":"en"}]}]},"item_1617258105262":{"attribute_name":"Resource Type","attribute_value_mlt":[{"resourcetype":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_1617265215918":{"attribute_name":"Version Type","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_ab4af688f83e57aa","subitem_version_type":"AM"}]},"item_1617353299429":{"attribute_name":"Relation","attribute_value_mlt":[{"subitem_relation_type":"isVersionOf","subitem_relation_type_id":{"subitem_relation_type_id_text":"https://doi.org/10.1016/j.oceaneng.2025.120460"}}]},"item_1617605131499":{"attribute_name":"File","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2027-02-05"}],"fileDate":[{"fileDateType":"Available","fileDateValue":"2027-02-05"}],"filename":"OE_322.pdf","filesize":[{"value":"2.5 MB"}],"format":"application/pdf","mimetype":"application/pdf","url":{"objectType":"fulltext","url":"https://hiroshima.repo.nii.ac.jp/record/2040746/files/OE_322.pdf"},"version_id":"b0048e57-7155-4b84-a36c-c27e22a24ce7"}]},"item_1732772494514":{"attribute_name":"備考","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"The full-text file will be made open to the public on 5 February 2027 in accordance with publisher's 'Terms and Conditions for Self-Archiving'"}]},"item_title":"Development of marine accident probability prediction model for pleasure boats using ship accident database in central part of Seto Inland Sea","item_type_id":"40036","owner":"79","path":["1730444907710"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2025-06-17"},"publish_date":"2025-06-17","publish_status":"0","recid":"2040746","relation_version_is_last":true,"title":["Development of marine accident probability prediction model for pleasure boats using ship accident database in central part of Seto Inland Sea"],"weko_creator_id":"79","weko_shared_id":-1},"updated":"2025-06-18T00:47:35.742964+00:00"}
