Abstract: A road surface damage detection device includes: a front-rear acceleration acquisition unit configured to acquire a front-rear directional acceleration of a vehicle during travelling of the vehicle; a position information acquisition unit configured to acquire position information indicating a current position of the vehicle; a damage state acquisition unit configured to acquire road surface damage information which is related to a road surface on which the vehicle travels and in which road surface damage of the road surface detected based on a change state of the acceleration, and the position information corresponding to a position where the road surface damage is detected are associated with each other; and a transmission unit configured to transmit the acquired road surface damage information to an outside of the vehicle.

Abstract: A road degradation information collecting device includes: a position detection unit that detects a traveling position of a vehicle; a speed detection unit that detects a speed of the vehicle; a degradation detection unit that detects degradation in a road surface of a road where the vehicle is traveling; a timing calculation unit that calculates a timing at which the vehicle passes through a position separated by a predetermined distance from a degradation position that is the traveling position at which the degradation is detected among traveling positions detected by the position detection unit on the basis of the speed detected by the speed detection unit; and a recording control unit that records a captured image obtained by imaging the road surface with an imaging unit the vehicle at the timing calculated by the timing calculation unit, on a storage unit in correlation with the degradation position.
