1. Evaluate current federal PM2 measures, both pavement condition measures and bridge measures, for performance thresholds, and overall performance measure with respect to: Consistency, Usefulness, and Alignment.
2. Identify and address in detail specific challenges for each condition measure for consistency, including thresholds. For example, determine if wheel path cracking considerations could be revised to provide more consistent results across pavement types (e.g. composite, concrete) and pavement widths (e.g. <12 ft.) 3. Provide recommendations to improve existing measures and/or identify metrics that better reflect conditions enhance decision-making taking into account not only the assessment of current and future condition but also their implications in economic analyses of long-term maintenance and rehabilitation.

NCHRP 20-24(37): This project, Measuring Performance among State DOTs: Sharing Good Practices, put in place a foundation on which the first set of national performance measures were created. A similar program needs to established on which to further develop relevant national-level performance measures.
