Physical quantity measurement method, measurement system, host system, and sensing apparatus

A host system comprising:

• a communication interface that communicates with a sensing apparatus;
• and
• a processor,
• wherein the sensing apparatus acquires a plurality of measurement results corresponding to passage of a plurality of vehicles based on measurement performed by a sensor for physical quantity computation attached to a structure through which the plurality of vehicles pass,
• the communication interface receives information that associates each of the measurement results with measurement time information representing time when the measurement result is obtained, and
• the processor identifies the vehicle corresponding to each of the plurality of measurement results based on the measurement time information and operation information that is information on an operation status of the vehicle and determines whether or not to use each of the plurality of measurement results in an abnormality evaluation process of evaluating abnormality of the structure based on a vehicle identification result that is a result of the identification of the vehicle.
