Performance Measures (Overview)
Federal legislation passed in 2012 introduced a new requirement to incorporate a performance-based approach into the transportation planning process. The federal transportation bill Moving Ahead for Progress in 21st Century Act (MAP-21) required state Departments of Transportation, MPOs, and transit authorities to set coordinated targets, report on a required set of performance measures, and prioritize projects using a coordinated performance-based planning process. These performance requirements were continued and bolstered by the Fixing America’s Surface Transportation (FAST) Act, which was signed into law in 2015.
A summary of the required National Performance Measures aligned with the seven National Goals is presented below. The EPMPO has adopted targets set by the states (TxDOT and NMDOT) for all National Performance Measures. This section summarizes the adopted targets for each of the measures and provides a performance target assessment.
The federal performance measures fall into three main categories—safety, maintenance, and performance. Safety measures track highway and transit deaths and injuries and include transit incidents like fires or crashes. Maintenance measures look at the age of transit fleets and the condition of roads and bridges. System performance measures look at highway congestion and reliability, freight movement, and environmental sustainability, including air quality.
NATIONAL GOAL | NATIONAL PERFORMANCE MEASURE(S) | |
Safety | - Fatalities (# and rate) | |
- Serious injuries (# and rate) | ||
- Number of non-motorized fatalities and serious injuries | ||
Infrastructure Condition | - % of Interstate pavements in Good & Poor condition | National Highway System = NHS |
- % of non-Interstate NHS pavements in Good & Poor condition | ||
- % of NHS bridges classified as in Good & Poor condition | ||
Congestion Reduction | - Annual hours of PHED per capita | Peak Hour Excessive Delay = PHED |
- % Non-SOV Travel | ||
System Reliability | - % of PMT on the Interstate that are reliable | Passenger Miles Traveled = PMT |
- % of PMT on non-Interstate that are reliable | ||
Freight Movement & Economic Vitality | - TTTR Index on the Interstate System | Truck Travel Time Reliability Index = TTTRI |
Environmental Sustainability | - % Change in CO2 Emissions on NHS Compared to Calendar year 2017 | |
Reduced project delivery delays | - No national measures in current legislation |

System Reliability & Freight (PM3)
Texas state targets for system performance and freight adopted by the EPMPO Transportation Policy Board are presented below. 2-year and 4-year targets for Texas and New Mexico were adopted on May 19, 2023.
SYSTEM RELIABILITY – TEXAS STATE TARGETS
PM3: SYSTEM RELIABILITY | Original Target | Baseline | 2-Yr Target | 4-Yr Target |
(Revised 2021) | 2021 | 2024 | 2026 | |
Interstate Reliability | 70% | 84.6% | 70% | 70% |
Non-Interstate Reliability | 70% | 90.3% | 70% | 70% |
Truck Travel Time Reliability | 1.76 | 1.39 | 1.55 | 1.55 |
SYSTEM RELIABILITY – NEW MEXICO STATE TARGETS
PM3: SYSTEM RELIABILITY | Original Target | Baseline | 2-Yr Target | 4-Yr Target |
(Revised 2021) | 2021 | 2023 | 2025 | |
Interstate Reliability | 95.1% | 98.5% | 95.1% | 95.1% |
Non-Interstate Reliability | 90.4% | 97.5% | 94.1% | 94.1% |
Truck Travel Time Reliability | 1.15 | 1.23 | 1.30 | 1.30 |
Travel Time Reliability: Think about travel time reliability as the consistency your travel time day-to-day and/or across different times of the day.
People who drive are used to some level of traffic, known as congestion, and plan for some delay, particularly during rush hour. Drivers might adjust their schedules or budget extra time to allow for traffic delays. But what happens when traffic delays are much worse than expected? When a crash on the roadway or poor weather slows you down, your normal travel time of 20 minutes could jump to 45 minutes. We are much less tolerant of unexpected delays because they can cause us to be late for work, miss appointments, or incur extra childcare fees. Travel time reliability measures the extent of this unexpected delay.
Truck Travel Time: Truck Travel Time Reliability (TTTR) Index is the metric used to assess the movement of trucks on the Interstate System. As with Travel Time Reliability, it is an attempt to measure the consistency or dependability in travel times for trucks on the Interstate.
By agreeing to support the System Performance & Freight (PM3) states’ targets the El Paso MPO agrees to:
Continue implementation of policies and programs aimed at maximizing the existing system capacity, reducing demand through implementation of travel demand management strategies, and strategically adding new interstate capacity.
A summary of the system reliability and freight performance measures trends and state targets can be found in page 17 of the Performance Based Planning & Programming Document (MTP Appendix D).
Congestion Reduction & Emissions Reduction (PM3)
Nonattainment MPOs are required to establish targets and report progress for the performance measures related to the Congestion Mitigation and Air Quality (CMAQ) program as established in 23 CFR Part 490 (§ 490.707 and § 490.807) for on-road mobile source emissions.
Traffic congestion and on-road mobile source emission reduction targets adopted by the EPMPO Transportation Policy Board on August 19, 2022, are presented below.
TRAFFIC CONGESTION TARGETS – EL PASO, TX-NM URBANIZED AREA
PM3: TRAFFIC CONGESTION | 2022 Baseline Score | 2-Yr Target | 4-Yr Target |
(2021 Actual) | 2023 | 2025 | |
Annual Hours of Peak Hour Excessive Delay (PHED) | 8.4 | 9 | 10 |
Percent of Non-Single Occupancy Vehicle (Non-SOV) | 20.2% | 20% | 20% |
Unlike the other measures, the CMAQ traffic congestion measures initially only applied to urbanized areas of more than one million population, in all or part of a nonattainment or maintenance area for ozone, carbon monoxide or particulate matter. For the second performance period, the population threshold for the congestion measure dropped to 200,000. Therefore, this is the first time the EPMPO is required to establish emission targets for the two traffic congestion measures. The second performance period for the two traffic congestion measures (PHED and Non-Single Occupancy Vehicle Travel, or SOV) began on January 1, 2022, and runs through December 31, 2025. (23 CFR 490.105 (e)(4)).
CMAQ – TEXAS STATE TARGETS
PM3: ON-ROAD MOBILE SOURCE EMISSIONS | Baseline | 2-Yr Target | 4-Yr Target |
2021 | 2023 | 2025 | |
Total Emissions Reduction: PM-10 (KG/DAY) | 5.42 | 4.54 | 8.90 |
Total Emissions Reduction: CO (KG/DAY) | 216.50 | 175.75 | 367.10 |

A summary of the congestion and emissions reduction performance measures requirements and basis for the adopted targets can be found in page 23 of the Performance Based Planning & Programming Document (MTP Appendix D).
TRANSIT ASSET MANAGEMENT (TAM)
As part of the FAST Act, performance measures were incorporated for transit agencies, primarily through the Transit Asset Management (TAM) assessment and planning requirements. Sun Metro’s TAM plan was developed to meet that requirement.
Initial targets were adopted in September 2018 in cooperation with local and state partners. In February 2023, The El Paso MPO Transportation Project Advisory Committee (TPAC) reviewed the existing plans and recommended that the El Paso MPO Transportation Policy Board (TPB) adopt an updated mixture of targets from TxDOT and Sun Metro for the El Paso MPO. These new targets include track segment performance, to reflect the opening of the El Paso Streetcar.
EL PASO TRANSIT ASSET MANAGEMENT 4 YEAR TARGETS
TRANSIT ASSET MANAGEMENT | 2023 TARGET |
% revenue vehicles at or exceeding useful life benchmark | <15% |
% service vehicles (non-revenue) at or exceeding useful life benchmark | <15% |
% facilities rated below 3 on condition scale (TERM) | <15% |
% track segments with performance restrictions | >95% |
On September 18, 2020 the El Paso MPO adopted the mass transit provider Sun Metro’s PTASP. Sun Metro developed their PTASP in compliance with the requirements on 49 CFR 673.11(a) (1-6). The performance measures adopted in this PTASP for fix route, streetcar and paratransit per every 100,000 miles are presented below.
