Method and device for evaluating service performance of traffic infrastructure health monitoring system

The invention relates to the field of traffic infrastructure health monitoring system service performance evaluation and calibration, in particular to a traffic infrastructure health monitoring system service performance evaluation method and device. The method comprises the following steps: placing provided external excitation in a road section monitored by a traffic infrastructure health monitoring system to be evaluated; acquiring corresponding feedback data when the external excitation acts in the road section through a provided standard sensor; constructing a prediction response model of the feedback data in the road section, and combining the prediction response model with the feedback data to obtain prediction data; actual measurement data are obtained through a traffic infrastructure health monitoring system to be evaluated; and evaluating and calibrating the service performance of the to-be-evaluated traffic infrastructure health monitoring system in combination with the prediction data and the measu
