Scenario Planning of Future Freight and Passenger Traffic Flows across the U.S.-Mexico and U.S.-Canada Borders

The U.S. Department of Transportation, through the Federal Highway Administration, initiated a study, in cooperation with Transport Canada and the Mexican Secretariat of Transportation and Communications, to develop U.S.-Mexico and U.S.-Canada projections of future freight and passenger volumes over the next 30 years (2015 – 2045) from a North American framework and a regional border perspective.

Disclaimer

This map is a tool to help determine where transportation conformity applies, but it may not be completely accurate or up to date in all cases. The information contained in this mapping tool is not intended to replace the transportation conformity regulations at 40 CFR Part 93, EPA guidance, Federal Register notices, or the EPA Green Book. Please see the full set of assumptions below.

Please contact Cecilia Ho, David Kall, or Eddie Dancausse at FHWA for any questions related to non-attainment/Maintenance areas or areas subject to transportation conformity analysis.

Data Sources:

EPA Green Book U.S. EPA. Green Book Data Download. AREADATA Excel sheet downloaded with export date of 12/31/2018.

U.S. EPA. NAAQS Designated Area Reports. Effective date of redesignation to maintenance for CO and PM10 areas obtained March 2021.

EPA’s Transportation Conformity Guidance for the South Coast II Court Decision.

See this FHWA webpage for additional static maps.

Assumptions:

This mapping tool assumes that transportation conformity requirements last for 20 years after the effective date of the re-designation to maintenance; however, in some cases the SIP may specify a budget year beyond that timeframe, which would extend the transportation conformity requirements.

Transportation conformity only applies to the following transportation-related pollutants: Ozone, PM2.5, PM10, carbon monoxide (CO), and nitrogen dioxide (NO2). Transportation conformity does not apply to lead or sulfur dioxide.

Transportation conformity no longer applies to areas from the 1997 PM2.5 standard that have been re-designated to maintenance (the standard was revoked for these areas). Transportation conformity will stop applying to the remaining nonattainment areas when they are re-designated to maintenance.

According to the USDA, a food desert is a census tract that has either at least 500 people or at least 33% of the population who live more than one mile from the nearest large grocery store for an urban area or greater than 10 miles for a rural area. In addition, the census tract has either a poverty rate greater than or equal to 20%, or a median family income less than or equal to 80% of the corresponding metropolitan or statewide median family income.

Other definitions include more than a half mile from the nearest large grocery store for urban areas and 20 miles for rural areas.

The National Network of conventional combination trucks was authorized by the Surface Transportation Assistance Act of 1982 (P.L. 97-424) and specified in the U.S. Code of Federal Regulations (23 CFR 658) to require states to allow conventional combinations on "the Interstate System and those portions of the Federal-aid Primary System … serving to link principal cities and densely developed portions of the States … [on] high volume route[s] utilized extensively by large vehicles for interstate commerce … [which do] not have any unusual characteristics causing current or anticipated safety problems."

Conventional combinations are tractors with one semitrailer up to 48 feet in length or with one 28-foot semitrailer and one 28-foot trailer, and can be up to 102 inches wide.

FHWA 2010 Adjusted Urban Area - For transportation planning purposes, federal transportation legislation allows for the outward adjustment of Census Bureau defined urban boundaries (of population 5,000 and above) through the cooperative efforts of State and local officials. By Federal rule, these adjusted urban area boundaries must encompass the entire census-designated urban area and are subject to approval by the Secretary of Transportation (23 USC 101(a) (36) - (37) and 49 USC 5302(a) (16) - (17).
