Performance Measures for Enhanced Bridge Management

The establishment of clear performance measures can help agencies to assess the extent to which a bridge program, project, or policy has succeeded or is expected to succeed in achieving intended goals and objectives. Chosen properly, a set of performance measures can adequately describe the full consequences of competing bridge actions and thereby help identify the most desirable. Typical bridge management goals and performance measures considered by bridge decision makers are identified. The research summarizes the best practices in quantifying a number of performance measures related to these goals. There is discussion of desirable properties not only of individual performance measures but also of any set of performance measures intended for any particular bridge evaluation problem.
