On Monday, January 9, the Federal Highway Administration (FHWA) released copies of the final rules for the last two national performance management measure regulations. The final rules were published in the Federal Register on January 18 and have an effective date of February 17, 2017. One rule establishes regulations to assess the condition and performance of bridges on the National Highway System (NHS) and of pavements on the Interstate and non-Interstate NHS. The other rule establishes regulations to assess the performance of the NHS, Freight Movement on the Interstate System, and the Congestion Mitigation and Air Quality Improvement (CMAQ) Program.
FHWA’s summaries of the measures included in the new rules include:
Six measures in the Bridge and Pavement Final Rule:
- Four measures of pavement condition:
- percentage of pavements on the Interstate System in Good condition
- percentage of pavements on the Interstate System in Poor condition
- percentage of pavements on the NHS (excluding the Interstate System) in Good condition
- percentage of pavements on the NHS (excluding the Interstate System) in Poor condition
- Two measures of bridge condition:
- percentage of NHS bridges in Good condition
- percentage of NHS bridges in Poor condition
Seven measures in the System Performance Final Rule:
- Three measures of system performance:
- percentage of reliable person-miles traveled on the Interstate
- percentage of reliable person-miles traveled on the non-Interstate NHS
- percent change in CO2 emissions from 2017, generated by on-road mobile sources on the NHS.
- A measure that will evaluate truck travel time reliability on the Interstate system (average truck reliability index).
- Three measures that will assess the CMAQ program:
- total emission reductions for applicable criteria pollutants, for non-attainment and maintenance areas
- Two measures to assess traffic congestion:
- annual hours of peak hour excessive delay per capita
- modal share; specifically, the percent of non-single occupancy vehicle travel, including travel avoided by telecommuting.
