Although system-level management was not listed as a primary use of performance measures by agencies, "ensuring accountability and responsiveness to stakeholders," which involves increasing network connectivity, is included as a fundamental reason for implementing and expanding performance management programs. • Many of the transportation issues of greatest concern to the public today are those that require the ability to address different systems as a single network (e.g., congestion, safety, and security)

This is both a challenge and opportunity for system-level performance measurement, presenting communication challenges while creating opportunities to combine resources and perspectives to create measures that more efficiently set goals and track progress to improve overall user experience. Best Practices in System-Level Performance Measures For system-level performance measures to be successful, strong partnerships, solid policies, and implementable practices must be in place.

Expanding performance measurement programs to include system-level considerations creates additional complexities that accompany any coordination of activities among multiple actors and stakeholder groups with divergent interests. The successful development and implementation of performance measurement at the organizational level involves many challenges.

These studies focus primarily on the collaborative elements of system-level performance measurement, such as best practices in developing systemlevel performance management programs and facilitating communication between partner agencies and jurisdictions. Very little is written about the actual performance measures used to successfully monitor system-level performance.

Land use impacts include • Corridor/access management; • Number of street connections per 100 acres; • Smart-growth policies; • Acres of mixed-use or transit-oriented development; • Open space and farmland developed; • Amount of land developed and developed per capita; • Job/housing balance; • Percentage of workers within 15 to 30 minutes of their job; • Percentage of jobs, dwelling units, and population within one-quarter and one-half mile of transit; • Percent growth in areas with good/poor accessibility; • Accessibility and number of destinations within 15 to 30 minutes of travel; and • Overall density and density of approved development. Environmental impacts include • Wetlands and forest developed; • VMT and VMT per capita; • Emissions and emissions per capita; • Gallons of gas consumed; • Percentage of new roads with sidewalk and bike lane/path; • Nonauto trips, transportation alternatives; • Modal share for all trips; • Water quality; • Storm runoff (quantity and quality)

Many of these processes rely on lower-level performance measures as inputs (e.g., mobility through monetized travel-time savings and safety through crash reductions and associated costs) and as a result are easily adapted to measuring performance at the system level.
