Performance Measures

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.

On January 20, 2023, the Transportation Policy Board approved a resolution to support the updated 4-year target (previously adopted January 21, 2022), for both Texas Department of Transportation (TxDOT) and the New Mexico Department of Transportation (NMDOT).

By agreeing to support the states’ HSIP targets, the EPMPO agrees to:

  • Work with the states and safety stakeholders to address areas of concern for fatalities or serious injuries within the metropolitan planning area. 
  • Coordinate with the states and include the safety performance measures and the states’ HSIP targets for those measures in the long-range regional transportation plan (RTP). 
  • Integrate into the metropolitan transportation planning process, the safety goals, objectives, performance measures and targets described in other state safety transportation plans and processes such as applicable portions of the HSIP, including the SHSP.
  • Include a description in the TIP (Transportation Improvement Program) of the anticipated effect of the TIP toward achieving HSIP targets in the RTP, linking investment priorities in the TIP to those safety targets.

A summary of the Highway Safety Improvement Program's (HSIP) safety performance measures trends and state targets can be found in page 5 of the Performance Based Planning & Programming Document (MTP Appendix D).

By agreeing to support the PM2 states’ targets the El Paso MPO agrees to: 

  • Work with the states and relevant stakeholders to address areas of concern for pavement and bridge condition within the metropolitan planning area.
  • Coordinate with the states and include the infrastructure condition targets for those measures in the long-range regional transportation plan (MTP).
  • Integrate into the metropolitan transportation planning process, the infrastructure goals, objectives, performance measures and targets described in other state transportation plans and processes.
  • Include a description in the TIP (Transportation Improvement Program) of the anticipated effect of the TIP toward achieving pavement and bridge condition targets in the MTP, linking investment priorities in the TIP to those infrastructure condition targets.

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.

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)).

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.

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.
