Abstract
A collision alert device includes a calculation part repeatedly calculating, at a prescribed time interval, a time-to-collision obtained by dividing a distance between moving objects by a relative velocity of two moving objects, the distance between moving objects being a distance between the two moving objects, and an output part outputting an alert in at least one of the two moving objects as a condition of the time-to-collision being equal to or less than a predetermined threshold, the relative velocity is a centripetal relative velocity of a moving velocity of each of the two moving objects, the centripetal relative velocity being calculated from a centripetal velocity that is a component along a line segment connecting a position of each of the two moving objects, and the time-to-collision is a centripetal time-to-collision obtained by dividing a distance between the two moving objects by the centripetal relative velocity.
