Bridge Health Monitoring Metrics: Updating the Bridge Deficiency Algorithm
As part of its bridge management systems, the Alabama Department of Transportation (ALDOT) must decide how best to spend its bridge replacement funds. In making these decisions. ALDOT managers currently use a deficiency algorithm to rank bridges that are the most deficient and in need of replacement. The current algorithm is outdated and needs to be revised to reflect modern bridge performance criteria. UTCA researchers established a new set of performance criteria that reflect modern ALDOT practice, set performance goals for each criterion and assigned importance to the criteria. The updated bridge deficiency algorithm was evaluated by comparing lists of bridges ranked in order of decreasing deficiency against the judgment of experience division bridge inspectors, the 194 bridges selected for replacement in the 2007 through 2011 bridge replacement program, and a similar list produced by the 1991 deficiency algorithm.
