Collision scenarios and probabilistic collision damage

Collision scenarios and probabilistic collision damage

This paper examines the influence of collision scenario random variables on the extent of predicted damage in ship collisions. Struck and striking ship speed, collision angle, striking ship type and striking ship displacement are treated as independent random variables. Other striking ship characteristics are treated as dependent variables derived from the independent variables based on relatio...

Probabilistic Method for Predicting Ship Collision Damage

Probabilistic Near Mid-Air Collision Avoidance

We propose a probabilistic method to compute the near mid-air collision risk as a function of predicted ight trajectory. The computations use state estimate and covariance from a target tracking lter based on angle-only sensors such as digital video cameras. The majority of existing work is focused on risk estimation at a certain time instant. Here we derive an expression for the integrated ris...

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...

Collision avoidance for aerial vehicles in multi-agent scenarios

This article describes an investigation of local motion planning, or collision avoidance, for a set of decisionmaking agents navigating in 3D space. The method is applicable to agents which are heterogeneous in size, dynamics and aggressiveness. It builds on the concept of velocity obstacles (VO),which characterizes the set of trajectories that lead to a collision between interacting agents. Mo...
