Key Points

To develop a systematic, dynamic voyage planning framework that generates initial waterways routes and updates them in real time to minimize ship collision risks.
Extracted similar historical Automatic Identification System (AIS) trajectories and identified centerline routes using Dynamic Time Warping (DTW) with dynamic cross-track distance (XTD) calculations.
Predicted the future navigation paths of surrounding vessels using Gaussian Process and Long Short-Term Memory (LSTM) models.
Assessed real-time collision hazards along the path to dynamically update and revise the initial route.
The dynamic route update model generated navigation corridors with lower collision risks compared to static initial routes.
The predictive framework successfully produced safer navigation trajectories without relying purely on navigators' qualitative experience.

Implication

Simulation study demonstrates dynamic route planning in port waterways, indicating reduced vessel collision risk.
