Transportation Performance Management

 

State Highway Reliability Report - New Mexico

The information below summarizes the TPM Highway Reliability performance measures, which include two highway reliability measures and one truck travel time reliability measure. Per 23 CFR 490, State Departments of Transportation (DOTs) are required to establish 2- and 4-year targets for these measures. The targets should represent the anticipated condition/performance at the mid-point and end of the 4-year performance period. State DOTs establish targets at the beginning of each 4-year performance period, and report on progress every two years. When establishing targets, State DOTs have the flexibility to use the methodology they deem most appropriate. FHWA encourages States to review data sets and trends and consider factors that may affect targets. Performance targets should be data-driven, realistic, and attainable and should align with the performance management framework and legislative intent.

The targets and discussion of basis for targets, optional adjustment of targets, progress, and planned activities were provided by the State DOT in its most recent biennial performance report. FHWA has not edited this information. It is provided to help bring context to the State DOT's performance targets and progress. The data in the tables and graphs is from the biennial performance report or HPMS data submittal as noted below each measure summary. Any questions about the information should be directed to the State DOT.

Data reported by State DOTs was collected in the previous year, representing the condition/performance at the time of collection. Thus, in the tables and graphs below, FHWA labels data with the year representing the condition/performance, rather than the year the data was reported. The same thing is done for the targets--the year represents when the corresponding actual condition/performance data will be collected, not reported. More Information.

Significant Progress Determination
FHWA determines significant progress for these measures after the mid-point and end of each performance period. A State has met or made significant progress toward target achievement if “actual” condition/performance is equal to or better than the established two-year target or “actual” condition/performance is better than baseline performance 23 CFR 490.109(e). As provided in 23 CFR 490.107(b)(2)(ii)(A), baseline condition/performance is derived from the latest data collected through the beginning date of the performance period. FHWA will classify the assessment of progress toward the achievement of an individual 2-year or 4-year target as “progress not determined” if a State provides the extenuating circumstance information required in 23 CFR 490.109(e)(5), and FHWA accepts the information.

    New Mexico utilized the following forecasting methodology 1. Setup calculate current volume and capacity; 2. Model Fitting through log-linear regression models are fit statistical model, associating LOTTR / TTTR with volume, capacity, and roadway attributes; 3. Updates forecast future volume based on growth rates, then update future capacity based on planned projects; and 4. Forecasting forecast future LOTTR / TTTR using updated volume and capacity. NPMRDS was used to calculate 2017 Baseline PM3 metric scores and free-flow speeds (specifically based on March 2018 NPMRDS data). HPMS was the source of traffic volume by vehicle type and road attributes (Functional classes, urban/ rural designations). Growth rates were generated from evaluating growth at permanent count stations around the state, and projects were taken from the planned 2018-2021 capacity projects in the STIP.

    The percent of reliable person-miles traveled on the Interstate improved from 2017 (97.00% reliable) to 2018 (97.45% reliable), and while the 2019 figure (96.9% reliable) decreased from 2018, that is still higher than the 2-year target (96.1% reliable), reflecting improvements to Interstate travel.

    N/A
    Portions of Interstate 25 in Albuquerque, NM, are being widened, and this effort will continue into the next two years. The Albuquerque metro area is one significant region of unreliable Interstate segments, and these projects are improving system reliability.

    Behind the data: For the first performance period only, baseline condition and 2-year targets are not required for the Non-Interstate NHS reliability measure.

    Freight reliability did not match modeled assumptions for forecasted freight reliability. While the 2019 target was exceeded, preliminary 2020 NPMRDS and traffic volume data indicates that the 2021 target will be achieved.

    N/A
    There will be additional improvements to I-25 in Albuquerque, including continued widening of portions of the Interstate.

Significant Progress Determination

This table shows FHWA’s most recent determination for the Infrastructure performance measures.

PLEASE NOTE: Each State’s performance target assessment is based on its own State-specific target methodology and program philosophy. Therefore, conclusions should not be drawn based only on the information in the Significant Progress Determination Results table. FHWA understands that each State’s program is unique and therefore does not prescribe a methodology for States to set targets. States have the flexibility to use the methodology they deem most appropriate when setting their performance targets.
