Notes: Targets with desired trends going up should be above the level stated, and down should be below the level stated. Federal rule allows state and MPOs to adjust four-year targets during the mid-performance (2-year) progress report. There are no monetary penalties involved with PM3. 1 The first reporting period is from 2018-2021 (Oct. 1, 2017 through Sept. 30, 2021 for CMAQ) with data and actuals submitted Dec. 16, 2022. 2 The current two-year target period for PM3 is for calendar years 2022-2023 with data and actuals submitted on October 1, 2024. The current four-year target period for PM3 is for calendar years 2022-2025 (Oct. 1, 2021 through Sept. 30, 2025 for CMAQ) with data and actuals submitted on October 1, 2026. These reports align with the federal fiscal year, which runs October 1 through September 30.

Washington meets targets for reliable travel times on interstate, non-interstate roads

Washington met its 4-year targets for Highway System Performance during the 2018-2021 reporting period. WSDOT reported 82.4% of person-miles traveled on the interstate system were reliable during this period, achieving the target of 68% or higher.

WSDOT also reported 87.8% of person-miles traveled on the non-interstate NHS System were reliable, achieving the target of being higher than 61.0%.

Level of Travel Time Reliability (LOTTR) is defined as the ratio of longer travel times (80th percentile) to a "normal" travel time (50th percentile), using data from FHWA's National Performance Management Research Data Set or equivalent. Data are collected in 15-minute segments during four time periods:

• Morning peak (6-10 a.m. Monday-Friday)
• Midday (10 a.m. to 4 p.m. Monday-Friday)
• Afternoon peak (4-8 p.m. Monday-Friday)
• Weekends (6 a.m. to 8 p.m.)

The measures are the percent of person-miles traveled on the NHS that are reliable (with 1.5 TTR or less being reliable and more than 1.5 TTR being considered unreliable).

Setting Washington's 4-year targets

WSDOT, in collaboration with Metropolitan Planning Organizations, finalized its four-year Transportation Performance Management targets for highway system performance, freight and Congestion Mitigation and Air Quality (CMAQ) on December 16, 2022. WSDOT's methodology for setting its new PM3 performance targets to be reported on October 1, 2024 and October 1, 2026 included:

• Congestion — Evaluated pre-COVID trend (2017-2019 data) and COVID trend (2020-2021 data); and used the average growth rate between those two to set new 2-year and 4-year targets.

These reports align with the federal fiscal year, which runs October 1 through September 30.

Washington meets freight movement reliability target

Washington met its 4-year target for Truck Travel Time Reliability (TTTR) Index during the 2018-2021 reporting period. WSDOT reported 1.49 of TTTR index in 2021, achieving its target to not exceed 1.75. The Truck Travel Time Reliability metric is defined as the ratio of the longer truck travel time (95th percentile) to a "normal" truck travel time (50 percentile). It is computed for five time periods:

• Morning peak (6-10 a.m. Monday-Friday)
• Midday (10 a.m. to 4 p.m. Monday-Friday)
• Afternoon peak (4-8 p.m. Monday-Friday)
• Weekends (6 a.m. to 8 p.m.)
• Overnights for all days (8 p.m. to 6 a.m.)

The TTTR measure is calculated by multiplying each segment's maximum TTTR metric with its length, and then divided by the total mileage of Interstate System. WSDOT uses FHWA's National Performance Management Research data (NPMRDS) to compute TTTR measure, and report the progress to FHWA.

Seattle area meets target for Peak Hour Excessive Delay, Spokane and Tri-Cities areas report PHED performance

The Seattle urbanized area met its target for Peak Hour Excessive Delay per capita for the first, four-year period (2018-2021) with 18.9, which was lower than the 4-year target of 28.0. While no targets were required for the Spokane and Tri-Cities urbanized areas, their 4-year actual for PHED was 11.4 and 3.9, respectively.

The Peak Hour Excessive Delay (PHED) measure for the second, 4-year performance period applies to urbanized areas of more than 200,000 population that include nonattainment or maintenance areas (ozone, carbon monoxide or particulate matter). All states and MPOs with NHS mileage overlapping within an applicable urbanized area must coordinate on a single, unified target. In the second midperformance period progress report (due October 1, 2024) 4-year targets can be adjusted, and 2-year actual conditions are reported.

Traffic congestion is measured by the annual hours of PHED per capita on the NHS. The threshold for excessive delay is based on the travel time at 20 mph or 60% of the posted speed limit travel time, whichever is greater, and will be measured in 15-minute intervals. Peak travel hours are defined as 6-10 a.m. on weekday mornings; the weekday afternoon period is 3-7 p.m. or 4-8 p.m., providing flexibility to DOTs and MPOs. The total excessive delay metric is weighted by vehicle volumes and occupancy. WSDOT must report on metrics annually for all mainline highways on the NHS for all applicable urbanized areas.

Seattle urbanized area meets Non-SOV travel target, Spokane, Tri-Cities urbanized areas report performance

The Seattle urbanized area met its Non-Single Occupancy Vehicle (SOV) travel target for the 2018-2021 reporting period with 36.4%, higher than the goal of 32.2%. While no targets were required for the Spokane and Tri-Cities urbanized areas during this period, their actual Non-SOV travel was 24.2% and 20.6%, respectively.

The rule for the second, 4-year performance period applies to urbanized areas of more than 200,000 people include air quality non-attainment or maintenance areas (ozone, carbon monoxide or particulate matter). All states and MPOs with NHS mileage that overlaps within an applicable urbanized area coordinated on a single, unified target and reported the measures for that area Dec. 16, 2022.

Setting Washington's 4-year targets

WSDOT, in collaboration with Metropolitan Planning Organizations, finalized its four-year Transportation Performance Management targets for highway system performance, freight and Congestion Mitigation and Air Quality (CMAQ) on December 16, 2022. WSDOT's methodology for setting its new PM3 CMAQ performance targets to be reported on October 1, 2024 and October 1, 2026 included:

• CMAQ peak hour delay — Based on the Texas Transportation Institute's recommended methodology, held the 4-year target from the first four-year cycle (2018-2021) the same for second 4-year cycle (2022-2025) 2- and 4-year targets.
• CMAQ Non-SOV — Evaluated 2017-2019 pre-COVID trend and use 2019 as baseline data to set the new 2-year and 4-year targets.

Notes: Targets with desired trends going up should be above the level stated, and down should be below the level stated. Federal rule allows state and MPOs to adjust four-year targets during the mid-performance (2-year) progress report. There are no monetary penalties involved with PM3. 1 The first reporting period is from 2018-2021 (Oct. 1, 2017 through Sept. 30, 2021 for CMAQ) with data and actuals submitted Dec. 16, 2022. 2 The current two-year target period for PM3 is for calendar years 2022-2023 with data and actuals submitted on October 1, 2024. The current four-year target period for PM3 is for calendar years 2022-2025 (Oct. 1, 2021 through Sept. 30, 2025 for CMAQ) with data and actuals submitted on October 1, 2026. These reports align with the federal fiscal year, which runs October 1 through September 30. The measure for Greenhouse gas reductions (CO2) was added in January 2024, and therefore does not have a 2-year target shown above.

Determining progress toward total emissions reduction

PM3 applies to all air quality nonattainment and maintenance areas—for ozone, carbon monoxide, coarse particulate matter (less than 2.5 to 10 micrometers in diameter) and fine particulate matter (2.5 micrometers or smaller)—in Washington. Targets must reflect cumulative emissions reductions to be reported in the CMAQ Public Access System.

Setting Washington's 4-year targets

WSDOT, in collaboration with Metropolitan Planning Organizations, finalized its four-year Transportation Performance Management targets for highway system performance, freight and Congestion Mitigation and Air Quality (CMAQ) on December 16, 2022. WSDOT's methodology for setting its new PM3 CMAQ performance targets to be reported on October 1, 2024 and October 1, 2026 included:

• CMAQ emissions — MPOs evaluated actual federal fiscal year (FFY) 2018-2021 emission values based on projects in maintenance areas in the CMAQ Public Access System. MPOs identified their FFY 2022-2025 target contributions based on projects selected for funding in maintenance areas, and WSDOT added these MPO values to get a statewide figure for each pollutant. Baselines for FFY 2022-2025 are based on 4-year actuals from FFY 2018-2021.
• GHG (CO2) reductions — Washington's 2025 target represents the emission levels on the glidepath to the Washington State Legislature's 2030 GHG limits (45% below 1990 levels by 2030) from current 2022 levels of 16.7 MMT to 13.4 MMT in 2025. This change in emissions is a 19.8% reduction during the 2022-2025 performance period. MPOs can either adopt their own GHG reduction target or agree to plan and program in support of the state target. MPOs are to provide documentation of their action relative to this by July 30, 2024.
