System Performance, Freight, and CMAQ (PM3)

The System Performance, Freight, and CMAQ measures (commonly known as PM3) are six measures related to the following aspects of the transportation system.

• Percent of Person Miles of Travel on the Interstate System that is Reliable (Level of Travel Time Reliability)
• Percent of Person Miles of Travel on the Non-Interstate National Highway System (NHS) that is Reliable (Level of Travel Time Reliability)
• Truck Travel Time Reliability
• Peak Hour Excessive Delay
• Percent Non-Single Occupancy Vehicle (Non-SOV) Travel
• Total Emissions Reductions (NOx and VOC)

Targets are established biennially for these measures as part of a four-year performance period, the second of which began in 2022. RTC adopted 2024 and 2026 targets for all PM3 measures in in September 2022, and reaffirmed 2026 targets for a subset of PM3 measures in September 2024. Additional action to reaffirm or adjust 2026 targets for the remainder of these measures is anticipated in early 2025.  A variety of teams coordinate these measures including Roadway Planning, Freight, Sustainable Development, and Air Quality.
