Abstract :
In this study, we have generalized our previous tool for assisting a safety engineer in assessing collision trajectories by extending from colliding objects with constant velocity to more general variable velocity ones. We have also highlighted that a linear system cannot be relied upon for handling a colliding object with variable velocity. To deal with such trajectories, past observations are weighted depending on velocities at those locations; priority is given to locations with reduced velocity. Based on this hypothesis, we have shown that the weighted system outperforms a linear one. The benefit is that it always issues a timely warning, even if the trajectory of the colliding object keeps on changing over time.
