Purpose – Most of the existing approaches for flight collision avoidance are concerned with local traffic alone for which the separation is based on the pairwise analysis of aircraft trajectory trends, which is not efficient with regard to some flight path requirements along waypoints. The purpose of this paper is to deal with the global collision avoidance problem which aims at separating airc...

This paper focuses on an overview of an autonomous navigation system in maritime transportation that is supplied with intelligent guidance to avoid collision, while respecting the COLREGs rules and regulations and using expert knowledge in navigation for close quarter’s manoeuvres. The proposed collision avoidance process consists of two modules: a fuzzy logic based parallel decision making mod...

In this paper, the authors introduced a new approach to find the optimal collision avoidance maneuver considering multi threatening objects within short period, while minimizing the fuel consumption and satisfying the acceptable collision probability. A preliminary effort in applying a genetic algorithm (GA) to those kinds of problems has also been demonstrated through a simulation study with a...

Anti-collision at sea is technically difficult to realize as it involves the complex interaction between human navigators, ships and surrounding topographical environment. Collision avoidance should be conducted by human navigators. This paper proposes a way to graphically present relevant information for collision avoidance to help the human navigators’ decision making. The display can provide...

Abs t r ac t A control strategy for sensor-based collision avoidance and the supporting experimental results are reported in this paper. The real-time arm control software cc)ntinuously monitors the object clistance measured by the proximity sensors. When this distance is less than a preset threshold, the collision avoidance control acticm is initiated to inhibit motion towards the object and t...
