15C H A P T E R 2 Background ResearchThe objective of the SHRP 2 C02 effort was to develop a comprehensive performance measurement framework that would support collaborative decision making. To produce the framework, the research team took both a broad look at performance measurement and management and a more focused look at the application of specific performance measures in practice.

A state DOT's strategic mission, vision, goals, and objectives are tied to day-to-day activities via regular review of performance results in core DOT business functions such as pavement and bridge preservation, transportation safety, traffic operations, and infrastructure maintenance. Performance-based management has three essential and interconnected components: program development, project delivery, and system monitoring and reporting: 1.

NCHRP Report 446: A Guidebook for Performance-Based Transportation Planning provides practitioners an extensive library of measures organized by the following categories: • Accessibility; • Mobility; • Economic development; • Quality of life; • Environmental and resource conservation; • Safety; • Operation efficiency; • System preservation; and • Measures relevant to multiple goal categories (Cambridge Systematics, Inc., 2000)

. The type of measures considered for transportation planning has grown to include not only those that consider input (time, capital, resources)

. Travel demand models in use by most state DOTs and MPOs do an excellent job of demonstrating the congestion reduction potential of highway capacity-adding projects and generating VMT estimates commonly used in safety analyses, but are limited in their ability to demonstrate additional "off-model" benefits or impacts.

to incorporate sustainability goals into the highway project delivery process, and New York now requires a greenhouse gas inventory to be completed by MPOs as part of transportation plan/program development. Though the trend is to expand the type of metrics included as part of project-level evaluation, transportation agencies are largely limited by data and tools needed to perform meaningful analyses.

This shift has been particularly noticeable in wetlands research, where some of the most advanced practices now focus on the performance of mitigated wetlands, rather than simply the volume. In New Jersey, for example, the Department of Environmental Projection has developed the Wetland Mitigation Rapid Assessment Tool, which seeks to assess whether a mitigated wetland – natural or created – will perform "wetland functions" in the future.
