摘要：	The Sufficiency Rating (SR) has been used by the Federal Highway Administration to establish eligibility for federal bridge funds. Increasingly, the states have viewed this system as needing improvement to better reflect bridge performance. Most states have begun implementing bridge management systems that require collection of element-level condition data that are more detailed than National Bridge Inventory (NBI) condition ratings. Hence, there is a need for new bridge performance measures that provide performance information that is more specific than that of the SR. Task 97 of National Cooperative Highway Research Program Project 20-07 was initiated by the American Association of State Highway and Transportation Officials in 1998 to develop new bridge performance measures. Four individual performance subindexes and a weighted composite index have been proposed. Databases of eight states with a combined total of 13,392 bridges were evaluated, and results are compared with the NBI SR.
