ICF International and the U.S. Department of Transportation (USDOT), Federal Highway Administration (FHWA), and Federal Transit Administration (FTA), along with experts from the transportation industry, collaborated to produce the Performance-Based Planning and Programming Guidebook. Over the past two decades, transportation agencies have increasingly applied performance management-a strategic approach that uses performance data to support decisions to help achieve desired performance outcomes. Performance-based planning and programming (PBPP) refers to the application of performance management within planning and programming processes of transportation agencies to achieve desired performance outcomes for the multimodal transportation system. This guidebook describes the PBPP process and provides examples of effective practices to help practitioners advance these approaches in their own planning and programming activities.
