| Abstract | Maritime route planning is a critical challenge in modern shipping, where efficiency, safety, and sustainability must be simultaneously addressed. We model the ocean not as a fixed map but as a changing spatio-temporal grid. This study presents a hybrid routing algorithm that relies on a spatio-temporal cost function to generate safe and fuel-efficient vessel trajectories. As a vessel progresses through oceanic grids, the algorithm dynamically evaluates routing costs on the fly, incorporating forecast conditions at the estimated time of arrival and historical patterns specific to the location and season. This adaptive framework ensures that the most relevant environmental information is applied to each segment of the voyage. An evolutionary algorithm is first used to produce multiple locally optimal routes, followed by a parallelized A* search that synthesizes these into a globally optimized path. By minimizing fuel consumption, enhancing safety, and reducing environmental risks, the approach contributes directly to the reduction of shipping-related emissions and supports climate-resilient operations. The outcomes demonstrate the potential of spatio-temporal optimization to improve maritime logistics while aligning with the objectives of the UN Decade of Ocean Science for Sustainable Development, promoting safer, smarter, and more sustainable ocean use. |
