Method and device for determining the condition of a bridge

A device for determining the condition of a bridge over which a plurality of vehicles may travel on a roadway of the bridge, the device comprising:

• a plurality of traffic sensors, each of the plurality of traffic sensors being configured and disposed for detecting a load of each vehicle of a plurality of vehicles traveling over the bridge, each of the plurality of traffic sensors being configured to generate load data for a detected load for each of the plurality of vehicles traveling over the bridge;
• a structure sensor disposed for detecting a structural response of the bridge, which structural response includes at least one of the following physical quantities:
• a vibration, a strain, a displacement, and a change in inclination of the bridge, which structure sensor is configured to generate structural data for the detected structural response;
• an evaluation unit for evaluating the load data for each of the plurality of vehicles, wherein the evaluation unit is operatively connected to the plurality of traffic sensors and to the structure sensor;
• and
• wherein the evaluation unit is configured to link the evaluated load data and the structural data to form a condition profile of the bridge, which condition profile provides the detected structural response of the bridge at a given point in time relative to the evaluated load data of the plurality of vehicles at the given point in time.
