With the continuous increase in seaborne trade volume, ship traffic density in port areas is rising, and navigation conditions in port waters are becoming more complex. Short-term ship traffic prediction in port waters is playing an increasingly critical role in ship traffic control and navigation safety management. To address the limitation of low accuracy in aggregate models, this paper, based on ship Automatic Identification System (AIS) data, employs a disaggregate method to construct a hybrid prediction model. This model combines the Long Short-Term Memory (LSTM) network with ships' historical trajectories to calculate short-term ship trajectories in port waters. The counts of ships' trajectories intersecting with an approach channel section are used to predict the short-term ship flow across the section. A numerical example from Ningbo-Zhoushan Port during June to December 2020 demonstrates that the forecasting accuracy of the proposed model reaches up to 80%, significantly higher than that of traditional aggregate models. The model developed here provides a technical foundation for ports to implement ship traffic control methods and improve channel utilization rates.

随着海运量的持续高涨,港区航道船舶交通流密度不断增加,港口水域通航环境日趋复杂,港口水域船舶短时交通流预测在航道交通组织与航行安全保障中的作用愈发重要。为解决集计预测模型精度低的问题,基于进港船舶自动识别系统(AIS)数据,采用非集计的方法构建长短时记忆网络(LSTM)与历史轨迹匹配的混合预测模型,用以计算港口水域船舶短时航行轨迹,把船舶航行轨迹与进港航道断面的交叉次数作为短时航道断面的船舶流量。基于2020年6—12月宁波舟山港水域的AIS数据的验证计算显示,非集计方法的预测精度高达80%,明显高于传统的集计方法,该方法的提出为港口实施航道交通流管控策略、提高航道利用率奠定了技术基础。

随着海运量的持续高涨,港区航道船舶交通流密度不断增加,港口水域通航环境日趋复杂,港口水域船舶短时交通流预测在航道交通组织与航行安全保障中的作用愈发重要。为解决集计预测模型精度低的问题,基于进港船舶自动识别系统(AIS)数据,采用非集计的方法构建长短时记忆网络(LSTM)与历史轨迹匹配的混合预测模型,用以计算港口水域船舶短时航行轨迹,把船舶航行轨迹与进港航道断面的交叉次数作为短时航道断面的船舶流量。基于2020年6—12月宁波舟山港水域的AIS数据的验证计算显示,非集计方法的预测精度高达80%,明显高于传统的集计方法,该方法的提出为港口实施航道交通流管控策略、提高航道利用率奠定了技术基础。

With the continuous increase in seaborne trade volume, ship traffic density in port areas is rising, and navigation conditions in port waters are becoming more complex. Short-term ship traffic prediction in port waters is playing an increasingly critical role in ship traffic control and navigation safety management. To address the limitation of low accuracy in aggregate models, this paper, based on ship Automatic Identification System (AIS) data, employs a disaggregate method to construct a hybrid prediction model. This model combines the Long Short-Term Memory (LSTM) network with ships' historical trajectories to calculate short-term ship trajectories in port waters. The counts of ships' trajectories intersecting with an approach channel section are used to predict the short-term ship flow across the section. A numerical example from Ningbo-Zhoushan Port during June to December 2020 demonstrates that the forecasting accuracy of the proposed model reaches up to 80%, significantly higher than that of traditional aggregate models. The model developed here provides a technical foundation for ports to implement ship traffic control methods and improve channel utilization rates.
