Claim 4:
5. The time point acquisition method according to claim 2, wherein
from the time-series data acquired as a response caused by the movement of the known formation moving vehicle on the superstructure and a plurality of temporarily set thresholds, observation information including the entry time point, the exit time point, and the number of the plurality of moving vehicles is acquired in association with each of the plurality of temporarily set thresholds,
environmental information including a structure length which is a length of the superstructure, a moving vehicle length which is a length of one of the plurality of moving vehicles, and an installation position of a contact portion of one of the plurality of moving vehicles with the superstructure is acquired,
a time change of a deflection amount in each of the thresholds temporarily set based on an approximate equation of the observation information, the environmental information, and deflection is acquired, a time difference in a predetermined determination level between each of the acquired deflection amounts and the time-series data is acquired, and
the threshold having a smallest time difference is acquired based on a correlation between the acquired time difference and the plurality of temporarily set thresholds, and is set as the predetermined threshold.
