Abstract
Information regarding moving bodies (00) that are in danger of colliding is collected at an appropriate frequency in accordance with the degree of danger. This information-collecting device has a risk calculation unit and a transmission-interval determination unit. The risk calculation unit receives, from a plurality of moving bodies, state information that includes locations and velocities and is transmitted at provided time intervals. The risk calculation unit also computes the distance between and relative velocities of two moving bodies. The transmission-interval determination unit computes an interval such that the higher the relative velocities of two moving bodies are relative to the distance therebetween, the shorter the interval is, and provides the computed interval to the moving bodies.
