A method for analysing and/or monitoring bridges for land vehicles, wherein a bend is continuously and contactlessly detected as a deflection of at least one element of the bridge, in particular under traffic load, and the detected bends are stored, and wherein minimum bends are repeatedly determined, in particular retrospectively, from the stored bends, wherein a minimum bend is a bend which, in comparison with other bends, has a small or in particular retrospectively, minimum bends being determined from the stored bends, a minimum bend being a bend which has a small or smaller deflection in comparison with other bends during a time interval, and the minimum bends being determined by means of a dynamic mean value of detected bends, the determination of the dynamic mean value being based iteratively, retrospectively and/or repeatedly on a subset of detected bends from all detected bends, the subset being determined by means of a consideration of all detected bends and their profile and/or deviations from one another and/or from a mean value of all detected bends within the time interval and/or a subset, wherein such detected bends are not part of the subset which have values which lie above and/or below at least one predetermined range around the mean value, and wherein in particular at least subsets of the determined minimum bends are repeatedly compared with one another, wherein, if the number of determined minimum bends falls below a minimum number and/or the frequency of determined minimum bends falls below a predetermined minimum frequency and/or a predetermined time period since the last determined minimum bend and/or between two determined minimum bends is exceeded, a notification and/or a control of the traffic flow over the bridge takes place. wherein minimum bends are repeatedly determined, in particular retrospectively, from the stored bends, wherein a minimum bend is a bend which, in comparison with other bends, has a small or in particular retrospectively, minimum bends being determined from the stored bends, a minimum bend being a bend which has a small or smaller deflection in comparison with other bends during a time interval, and the minimum bends being determined by means of a dynamic mean value of detected bends, the determination of the dynamic mean value being based iteratively, retrospectively and/or repeatedly on a subset of detected bends from all detected bends, the subset being determined by means of a consideration of all detected bends and their profile and/or deviations from one another and/or from a mean value of all detected bends within the time interval and/or a subset, wherein such detected bends are not part of the subset which have values which lie above and/or below at least one predetermined range around the mean value, and wherein in particular at least subsets of the determined minimum bends are repeatedly compared with one another, wherein, if the number of determined minimum bends falls below a minimum number and/or the frequency of determined minimum bends falls below a predetermined minimum frequency and/or a predetermined time period since the last determined minimum bend and/or between two determined minimum bends is exceeded, a notification and/or a control of the traffic flow over the bridge takes place.
