The one-day peer review focused on how state Departments of Transportation (DOTs) are using performance measures to improve planning practices. Representatives of 13 DOTs shared their approaches and discussed the successes and challenges experienced in programming and planning. The agencies presented diverse approaches to performance measurement and demonstrated that states can tailor the implementation of performance measures to their own particular transportation context and needs. Attention to performance measurement in transportation planning is growing, in part because many state DOTs face increasing planning responsibilities while staffing and budget resources are limited. The ability to measure the success of current processes can help state DOTs use their limited resources more effectively. The information shared during this peer review also shows how performance measures can become an effective tool for communicating an agency's performance and decision-making rationale to local and state officials and to the public.
