[...] the level of understanding of how bridges perform and how to measure their performance satisfactorily fidls well short of the optimum. Because of a general lack of critical data and an inadequate understanding of the multiple causeand-effect relationships that govern the many aspects of bridge performance, most attempts at assessing that performance rely only on expert opinion, assumptions, and generalizations. [...] improved performance measures will help transportation personnel evaluate bridge serviceabity and durability; improve design, construction, and maintenance strategies; establish priorities for resource allocations within the transportation system and within the bridge infrastructure; evaluate organization-wide policies and programs; improve system reliability and accountability; and establish risk-based evaluations of bridges vulnerable to catastrophic faUure.
