PM3: System Performance

The PM3 category considers a multitude of factors related to maintaining the State’s economy and quality of life. Because the NFRMPO region currently has under 1,000,000 residents, there are a reduced number of performance measures prior to 2022.

Travel Time Reliability Index (TTRI)

Travel time reliability indexing (TTRI) is a multistep process to determine the ratio of peak travel periods to normal travel periods. The first step is to consider travel time reliability (TTR), which compares the 85th Percentile Travel Time to the 50th Percentile Travel Time. This information is collected using the National Performance Management Research Data Set (NPMRDS) and is collected in 15-minute segments between 6:00 a.m. and 8:00 p.m. A reliable travel time is considered a TTRI below 1.5.

Travel Time Reliability Index (TTRI)

Performance Measure Statewide Baseline Statewide Target
Percent of person-miles traveled on Interstate system that are reliable 80.7% 79%
Percent of person-miles traveled on non-Interstate system that are reliable 86.2% 94%
Truck Travel Time Reliability Index (TTTRI) 1.37 1.46

Air Quality

The NFRMPO region is part of the Denver Metro-North Front Range 8-Hour Ozone Nonattainment Area, comprising the Northern Subarea. In addition, the cities of Fort Collins and Greeley are in attainment for Carbon Monoxide, currently in maintenance. As a result, the NFRMPO must set performance measures related to the reduction of Volatile Organic Compounds (VOCs), Carbon Monoxide (CO), and Nitrogen Oxides (NOx). These are related to projects funded through the Congestion Mitigation and Air Quality (CMAQ) program.

Air Quality

Performance Measure Statewide Baseline Statewide Target
Volatile Organic Compounds (VOC) Reduction 672.78 kg/day 482kg/day
Carbon Monoxide Reduction 9,998.719 kg/day 5,393 kg/day
Nitrogen Oxides Reduction 672.780 kg/day 1,086 kg/day

Traffic Congestion

For the second performance period, the NFRMPO was required to establish two- and four-year targets for two Traffic Congestion Performance Measures. These two new targets are Percent of non-single occupant travel and annual hours of peak hour excessive delay (PHED) per capita for travel on the NHS system. Unlike the other PM3 targets, the traffic congestion targets are only required for the Fort Collins Urbanized Area and must be established as a joint target with the CDOT. The two Traffic Congestion targets were adopted by the NFRMPO Planning Council in June 2022 with Resolution 2022-17.

Traffic Congestion

Performance Measure Two Year Target Four Year Target
Non-Single Occupant Vehicle (SOV) Travel 25.3% 25.6%
Annual Hours of Peak Hours Excessive Delay (PHED) 3.8 3.7
