Time-to-collision and Collision Avoidance Systems
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...
متن کاملDistributed Reactive Collision Avoidance for Multivehicle Systems
The focus of this paper is the n-vehicle collision avoidance problem. The vehicle model used here allows for three-dimensional movement and represents a wide range of vehicles. The algorithm works in conjunction with any desired controller to guarantee all vehicles remain free of collisions while attempting to follow their desired control. This algorithm is reactive and distributed, making it w...
متن کاملCollision Avoidance for Multiple Agent Systems
Techniques using gyroscopic forces and scalar potentials are used to create swarming behaviors for multiple agent systems. The methods result in collision avoidance between the agents as well as with obstacles.
متن کاملAutomatic Collision Avoidance Systems: Towards 21st Century
More than about sixty per cent of casualties at sea are caused by collisions ref.1. So the results from the solution to this problem is the most urgent issue that we must face. Many measures have already been developed, but the ACAS will be new and possibly one of the most effective. A large proportion of accidents are caused by human error and the right approach to automation could help to red...
متن کاملOptimization-Based Collision Avoidance
This paper presents a novel method for reformulating non-differentiable collision avoidance constraints into smooth nonlinear constraints using strong duality of convex optimization. We focus on a controlled object whose goal is to avoid obstacles while moving in an n-dimensional space. The proposed reformulation does not introduce approximations, and applies to general obstacles and controlled...
