Synthesis of Information Related to Highway Practices. Topic 51-19. Performance Metrics for Public-Private Partnership

The infrastructure in the United States, as in many other countries, is aging, and limited public funds are available to maintain the current infrastructure and foster future growth. A potential mechanism to deliver a portion of the ongoing transportation infrastructure needs is a public-private partnership (P3). By definition, a P3 is a contract between the public and private sectors for the financing, delivery, or service of a project. There are many examples of successful P3’s in the U.S. and in other parts of the world. In recent years, establishment of the U.S. Department of Transportation Build America Bureau and enabling legislation in many states have facilitated implementation of P3 projects in the transportation sector. Once a project delivery selection is made, monitoring project performance over the length of the project becomes vital for assessing and improving project performance and delivery decisions. Performance metrics in P3 projects should address the DOT’s policy goals and the overall quality and performance requirements for the specific contracted work. These performance metrics typically include key indicators of travel time reliability, safety, overall project physical condition, asset availability, and other project elements. Despite the importance of performance metrics, knowledge is relatively limited about effective practices for selecting metrics, setting metric performance levels, and reasonable approaches to deductions and point systems for failure of the P3 contractor to meet contract requirements. The objective of this synthesis is to document key performance metrics used in various long-term DOT P3 contracts for the delivery of highway projects and/or services. The synthesis will focus on the post-construction stage of P3 contracts. Information gathered includes, but is not limited to: Key performance metrics for various DOT P3 contracts and how the metrics are implemented, tracked, and assessed; Categories of P3 metrics (e.g., environmental, tolling operations, pavement); Hand-back requirements; Methods by which performance metrics are tied to payment mechanisms (e.g., lane availability, route performance, condition criteria, safety performance, unforeseen events) to the P3 contractor; Methods for enforcing key performance metrics; and Lessons learned. Information will be collected through literature review, a targeted survey of DOTs that have enabling P3 legislation and that have reached commercial and/or financial close, and follow-up interviews with selected agencies for the development of case examples. Information gaps and suggestions for research to address those gaps will be identified.
