Abstract: A communication unit (2020) performs directly wireless communicates with a portable terminal (3000). A collection information acquisition unit (2040) acquires collection information. A division transmission unit (2060) generates multiple pieces of partial collection information by dividing the collection information, and transmits pieces of partial collection information being different from each other to multiple portable terminals (3000). A redundancy transmission unit (2080) transmits the same collection information to the multiple portable terminals (3000). An index value acquisition unit (2100) acquires any one or two of a reliability index value and a capacity index value of the portable terminal (3000). Based on any one or two of the reliability index value and the capacity index value of each portable terminal (3000), a transmission control unit (2120) selects the division transmission unit (2060) or the redundancy transmission unit (2080) to perform the transmission.

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.
