The study develops a tool for calculating transportation system performance metrics using the National Performance Management Research Data Set (NMPRDS) and other databases. The authors conduct a literature review to characterize effective strategic, programmatic and tactical TSMO practices; administer a survey to characterize the status of Georgia Department of Transportation (GDOT) using the TSMO CMM, and offer recommendations to move GDOT to the next level. Subsequently, the authors develop a tool to analyze and report on transportation system performance using the Moving Ahead for Progress in the 21st Century (MAP-21) system performance measures (PM3). The PM3 Tool calculates metrics for travel time reliability on interstate and non-interstate routes on the National Highway System (NHS), truck travel time reliability, and annual hours of peak-hour excessive delay per capita, and reports on percent of non-single occupancy vehicle (SOV) travel, and total emission reductions. It uses data from the NPMRDS, GDOT, the U.S. National Census and the Congestion Mitigation and Air Quality (CMAQ) Public Access Database. The study highlights the importance of developing TSMO at the tactical, programmatic and strategic levels simultaneously, integrating TSMO activities with strategic and long range planning and asset management functions within state departments of transportation (DOTs). Using the PM3 tool, state DOTs can calculate PM3 measures and use them in setting future performance targets, while working at the strategic, programmatic and tactical levels to improve transportation system performance.125
