1. A method comprising:
receiving, for each of a first plurality of consecutive time periods, an acceleration value associated with a first location of a structure supporting a roadway;
determining a first value of a first indicator based on absolute values of the acceleration values;
determining a plurality of pairs of consecutive-in-time acceleration values of the received acceleration values;
determining differences between the acceleration values of each of the plurality of pairs of consecutive-in-time acceleration values;
determining absolute values of the differences between the acceleration values of each of the plurality of pairs of consecutive-in-time acceleration values;
determining a second value of a second indicator by determining a sum of the absolute values of the differences between the acceleration values of each of the plurality of pairs of consecutive-in-time acceleration values;
determining a first value of an index based on the first value and the second value;
identifying a structural fault of the structure based on the first value of the first indicator and the first value of the index; and
in response to identifying the structural fault, activating a barrier on an end of the roadway to prevent traffic from entering the roadway.
