In this paper, we propose a novel CBR-based approach for ship collision avoidance. After the introduction of the CBR-based decision-making support, we present two abstraction principles, selecting view points and describing granularity, to create collision avoidance cases from real-time navigation data. Several issues related case creation and CBR-based decisionmaking support are discussed in d...

Avoiding collisions is one of the most basic needs of any mobile agent, both biological and technical, when searching around or aiming toward a goal. We propose a model of collision avoidance inspired by behavioral experiments on insects and by properties of optic flow on a spherical eye experienced during translation, and test the interaction of this model with goal-driven behavior. Insects, s...

In research on Traffic Conflicts Techniques, Time-To-Collision (TTC) has proven to be an effective measure for rating the severity of traffic conflicts and for discriminating critical from normal behaviour. The results of several studies point to the direct use of TTC as a cue for decision-making in traffic. The current development of driver support systems based on the application of modern te...

In this paper, an automatic pre–crash collision avoidance strategy for cars is presented. It produces a collision avoidance manoeuvre, if feasible, or, otherwise, an emergency braking to reduce the energy at the impact. The manoeuvre is generated relying on the use of sliding mode control. The performances of the proposed collision avoidance system are tested on a scaled radio–controlled car an...

This paper presents a technique for providing collision avoidance of arbitrary objects in a computer graphics system. The recursive algorithm implements the method of avoiding the collisions by taking an alternate path and therefore among the available alternate paths, the shortest one is chosen. Under the cluttered environment, maneuvering among the static and moving obstacles is the biggest h...

Distributed Reactive Collision Avoidance Emmett Lalish Chair of the Supervisory Committee: Professor Kristi A. Morgansen Aeronautics and Astronautics Collision avoidance is an important aspect of multivehicle coordination because it prevents vehicles from disrupting or destroying each other. The work contained in this dissertation concerns a novel approach to the n-vehicle collision avoidance p...
