This project contains data and code used to analyze the behavior of the collision risk model used by the U.S. Fish & Wildlife Service to predict the number of Bald and Golden eagles that will be killed at proposed wind energy facilities. These predicted fatalities determine the amount of off-site mitigation required to obtain a permit exempting the

Collision risk assessment for ships
Journal of Marine Science and Technology, 2010Efficient maritime navigation through dynamic obstructions at close range is still a serious issue faced by mariners. There have been studies focusing on collision risk assessment in the past, but the majority were based on the first person perspective, with area-based ship domain concepts that are defined around either the ownship or the obstacle ...

Collision risk analysis based train collision early warning strategy
Accident Analysis & Prevention, 2018A Train Collision Early Warning System (TCEWS) has been developed for collision avoidance. However, there are few studies regarding how to evaluate the collision risk and provide an early warning concerning a preceding train on the railway. In this paper, we have found that the time for collision avoidance is constrained by the timing of events, such ...

The Calculation of Marine Collision Risks
Journal of Navigation, 1985It has been recognized for some time that calculations of potential encounter rates based on the speed and lateral distributions of ships using sea routes provide only a partial estimation of the actual collision risk, as all encounters are usually given equal rating, and no attempt is made to include factors such as the degree of domain penetration or

Time to Collision and Collision Risk Estimation from Local Scale and Motion
2011Computer-vision based collision risk assessment is important in collision detection and obstacle avoidance tasks. We present an approach to determine both time to collision (TTC) and collision risk for semi-rigid obstacles from videos obtained with an uncalibrated camera. TTC for a body moving relative to the camera can be calculated using the ratio of
