Abstract
Accurate prediction of vessel arrival time (VAT) to port is essential for optimizing port operations, particularly given the common discrepancies between the vessel-reported estimated time of arrival (ETA) and its actual time of arrival (ATA). Traditional VAT prediction models predominantly rely on either static port call data (e.g., ETA and ATA) or dynamic automatic identification system (AIS) data, with limited integration of both sources to comprehensively address forecasting needs and biased forecasting results. To address these limitations, this study introduces a framework that, for the first time, integrates static port call data with dynamic vessel AIS data using a time-based comparative interpolation method to enhance VAT prediction accuracy. By synchronizing scheduled operations with real-time vessel movements, our approach captures nuanced temporal variations, significantly enhancing VAT prediction accuracy. Based on a tree-based stacking model and real-world vessel arrival data from Hong Kong Port (HKP), the proposed framework leverages the strengths of tree-based methods in handling tabular data and demonstrates substantial improvements in VAT prediction accuracy. Our results show an 54.53% reduction in mean absolute error (MAE) (from 6.84 to 3.11 h) and an 50.14% reduction in root mean squared error (RMSE) (from 10.61 to 5.29 h) compared to vessel-reported ETAs. Key features such as vessel-reported ETA, vessel sailing speed, vessel physical features, and spatiotemporal AIS data contribute to these improvements. This research addresses a critical gap by providing a unified approach that leverages both static and dynamic data sources, offering port authorities a more reliable and robust tool for vessel arrival forecasting and the subsequent informed port resource planning.
