The truss bridge face situation that I utilized the data acquired by an in-vehicle three-dimensional motion sensor with a GPS and suffered by a shipping collision in October, 2018, before suffering, the displacement situation of just after the suffering and the roadway surface after an emergency repair was presumed. These measured data, the pitch, roll and yaw angle data are utilized, the vertical slope of the bridge face, cross slope and a direction angle are presumed respectively and one according to the time is graphed. It was piled up and compared and the area it influenced by an accident.
