NCTCOG actively monitors the performance of the region’s transportation system. Many of these observations are adopted as formal performance measures that are used to tell the story of how the region’s transportation system is performing relative to the agency’s goals and objectives. Performance measurement is an area of rapid development for the Transportation department as it strives to improve its performance-based planning process.
What is performance measurement?

Ongoing Performance Measurement Activities
Performance measurement is a formalized framework for relating raw performance data to the goals and objectives of an agency or a specific plan. Not unlike professionals in other disciplines, planners use performance measures to quickly summarize the region’s performance, inform performance-based project selection/prioritization, assess progress toward goals over time, and communicate progress with stakeholders and the public.
Key elements of a performance measurement framework:
- Goal: Long-term general statements that summarize the region’s priorities
- Example: Increase mobility on the region’s transportation system
- Objective: Measurable, specific strategies to attain a goal
- Example: Reduce congestion on roadway facilities during peak travel times
- Performance Measure: Specific, repeatable assessment of how the region/study area is progressing toward an objective
- Example: Regional Peak Period Regional Travel Time Index (TTI)
- Target: Specific milestone for a performance measure that represents a desired future condition
- Example: Reduce regional Travel Time Index to 1.30 by 2022
- Metric: Subarea or segment-level calculations of performance that are typically aggregated into measures
- Example: Peak Period Travel Time Index on each roadway segment in the region
- Source Data: The continuously updated source of data from which metrics and measures are calculated
- Example: National Performance Management Research Dataset (NPMRDS) travel time data
Federal transportation rulemaking requires that MPOs such as NCTCOG monitor and set targets for a specific array of measures. As appropriate, targets for North Central Texas have been adopted by the Regional Transportation Council (RTC), and they are being incorporated into NCTCOG’s transportation planning processes.
Performance in Mobility Plans
Performance of the transportation system is a key component of the decision-making process in NCTCOG’s current long-range metropolitan transportation plan, Mobility 2045
. It includes a discussion of the system’s performance in the Regional Performance chapter
that incorporated the latest required Federal performance measures and a performance-based project selection process. Selected modeled roadway performance data is also available through the Mobility 2045 Roadway Performance mapping application
. Subsequent updates and new plans will further strengthen this component of the long-range planning process.
Performance in the Transportation Improvement Program
Much like Mobility 2045, the 2019-2022 Transporation Improvement Program (TIP)
contains a robust discussion of performance measurement and the impact that it has on the projects that the TIP selects for funding in its Regional Performance chapter
Progress North Texas
Progress North Texas is an annual report, published in the spring, summarizing transportation system performance, recent accomplishments, and next steps for transportation plans, policies, programs, and projects.
511DFW is a free traveler information service provided by NCTCOG and its partner agencies that aggregates live performance data and other relevant information into a single application.
Transportation Safety Program
As part of its Transportation Safety program, NCTCOG actively monitors crash data from the TxDOT Crash Records Information System (CRIS). Selected data is aggregated and published in a series of annual fact sheets. In recent years, these reports have been modified to include the required Federal safety performance measures.
Transportation Usage Measures
NCTCOG monitors the price of fuel and the impact it has on various aspects of the region’s transportation system.
Upcoming Performance Measurement Activities
- RTC adoption of initial targets for Federally-required Transit Safety performance measures
- A suite of formalized measures beyond the Federally-required measures to reflect the region’s goals
- Expanded performance measurement in upcoming metropolitan transportation plan updates
- Performance measurement dashboards
