Performance Measures

Federal surface transportation legislation, beginning with MAP-21 in 2012, established performance requirements under the Transportation Performance Management (TPM) program. These requirements covered:

  • Gathering data for national performance measures (PM);
  • Performance target setting at State and MPO level;
  • Coordination between States and MPOs; and
  • Reporting on performance at regular intervals.

As a multi-state metropolitan planning organization, HEPMPO plans and programs projects in the Transportation Improvement Program (TIP) to accomplish each State’s (MD and WV) targets and will report baseline performance and progress in a system performance report.  Below is a listing of the performance measures:
