The proposed approach is designed to be part of a decision support system for the bridge operators, in order to enhance traditional navigation. Focusing on the maritime field, a review of the scientific literature dealing with motion planning is presented, showing potential benefits and weaknesses of the different approaches. Among the several methods, details on RRT and RRT* algorithms are given. The ship path planning problem is introduced and discussed, formulating suitable cost functions and taking into account both topological and kinematic constraints. Eventually, an existing time domain ship simulator is used to test the effectiveness of the proposed algorithm over a number of realistic operation scenarios. The obtained results are presented and critically discussed.  000007731 542__ $$fCC-BY-NC-ND-4.0 000007731 6531_ $$aCollision Avoidance 000007731 6531_ $$aShip Simulator 000007731 6531_ $$aPath Planning 000007731 6531_ $$aRRT 000007731 7001_ $$aZaccone, R$$uDept. of Electrical, Electronic, Telecommunications, Naval Architecture and Marine Engineering (DITEN), Polytechnic School of Genoa University, Genova, Italy. 000007731 7001_ $$aMartelli, M$$uDept. of Electrical, Electronic, Telecommunications, Naval Architecture and Marine Engineering (DITEN), Polytechnic School of Genoa University, Genova, Italy. 000007731 773__ $$tConference Proceedings of iSCSS 000007731 773__ $$jiSCSS 2018 000007731 789__ $$whttps://zenodo.org/record/2536957$$2URL$$eIsIdenticalTo 000007731 85641 $$uhttps://www.imarest.org/iscss$$yConference website 000007731 8564_ $$9123b6efe-7bfc-445c-b0a7-1df2228bf4f8$$s1715449$$uhttps://library.imarest.org/record/7731/files/ISCSS%202018%20Paper%20067%20Martelli%20SDG%20FINAL.pdf
