Data coverage: Data for government expenditures in this table reflect outlays for all phases of the acquisition, construction, operation and maintenance of the relevant transportation facilities and equipment as well as expenditures pertaining to related engineering and technical surveys. This function now includes the government transfers to its own business enterprises engaged in the transportation activities, especially public transit and railway services.
Air: Data reflect expenditures for navigational, air traffic and other related services, operating subsidy payments to regional air carriers and municipal airports, grants to flying clubs and payments for international air navigational services. At the provincial level, data include assistance to the aviation industry, municipal airports and other related services. At the local level, data include outlays related to municipal airports.
Water transport: Data reflect expenditures on development, maintenance, operation and control of navigational channels, canals, harbor and wharf facilities, ferries that do not form integral part of road systems, landings and other marine facilities. It also includes the costs of the related operations of the Coast Guard and certain northern transportation services.
Pipeline, oil and gas: Data reflect expenditures on the operation, construction, use and maintenance of pipeline as well as grants and contributions to support the operation, construction and maintenance of pipeline systems. Data are no longer available separately.
Rail: Data reflect expenditures on the development, implementation and monitoring of policies and programs related to railway network rationalization and effectiveness. Rail data also include payments for railway relocation, contributions to railway passenger services infrastructure and to freight movements in certain geographical regions as well as grants for operations of railway facilities to resource areas.
Road: Data reflect expenditures on highways, secondary roads, roads to resource areas, boulevards, avenues and streets together with related storm sewers (where separated from sanitary sewers). Bridges, over and underpasses and road tunnels incorporated in highways also are included as well as those ferries that are usually operated by highway departments and form integral parts of road systems. Such ferries are distinguished from major lake and seagoing vessels and their supporting operations, which (if not classified as business enterprises), are assigned to the “water transport” category. The road data also include the costs of removing snow, debris, leaves and other deposits as well as surface sanding and flushing, expenses pertaining to traffic control and parking facilities.
The information corresponds to the 2008 base year.
The 1993 base calculations were developed until the year 2004 due to the transition change of the 2003 base year; 2003 base year was carried out until the year 2011; 2008 current base year considers 2003-2015 series. Retrospective series of this new base year back to the year 1993 will be done in the short term.
Table 2-2 presents data on transport expenditures of federal, state and municipal Government of the United Mexican States.
Air: Data reflects expenditures for air traffic navigation services and related services as well as the airport costs of the federal government.
Water: Data reflects expenditures for the maintenance of maritime and river works construction, and the exploitation and control of ports and harbors, as well as the maritime transport of oil and gas construction.
Pipeline, oil and gas: Data are composed by expenditures incurred in the construction, maintenance and use of pipeline systems by Petróleos Mexicanos (PEMEX).
Rail: Data reflect the costs incurred by the federal and state governments in the construction of infrastructure for electric and rail transport in addition to expenditures on services such as electric transport system (trolleybus) as well as the collective transportation system (Metro).
Road: Data correspond to expenditures incurred by the federal and state governments in construction, maintenance and management of highways, roads, bridges and similar as well as the installation of signs and protection road works and also expenses in the collective transport urban and suburban of passenger and goods
Table 2-2 presents transportation expenditure data for federal, state and local government in the United States. The data are obtained from the new Government Transportation Financial Statistics report. The new GTFS provides comprehensive and detailed statistics on government transportation financial statistics based on a new conceptual framework. The new conceptual framework introduces significant changes in the methodology, including definition, coverage, classification and presentation and sources of data. As a result of these changes, the data in the new GTFS report are not comparable to the data in earlier editions of the report.
The federal components of transportation expenditure estimates in GTFS are primarily from annual publications of the Budget of the United States Government from the Office of Management and Budget (OMB), and the Highway Statistics report from the Federal Highway Administration (FHWA). The new GTFS report makes adjustments to the federal expenditure data that are obtained from OMB, while earlier editions of the report provided federal expenditure data as reported in the budget without any adjustment. Outlays in the budget are reported on a net-basis after deducting offsetting collections. These offsetting collections are those applied directly to fund agency or program outlays rather than being transferred to the Department of the Treasury. For this reason, outlays reported in the budget may not necessarily indicate how much the federal government actually spends on transportation each year. Unlike the budget, the new GTFS report presents federal outlays on a gross-basis without deducting offsetting receipts so that the outlays indicate the actual costs of the federal government for providing and maintaining transportation infrastructure and services.
State and local government expenditure statistics in the new GTFS report are assembled from different data sources. Expenditure data for air and water transportation are obtained from annual survey of State and Local Government Finances of Census Bureau, which reports comprehensive statistics on state and local government financial activities. The highway component of the state and local government expenditures are from the Highway Statistics report of the Federal Highway Administration (FHWA). The Highway Statistics report provides more details and covers more highway activities than the State and Local Government Finances of Census Bureau provides. For example, the Highway Statistics covers government outlays for highway law enforcement, which are not covered by the State and Local Government Finances. Highway law enforcement refers to patrols or policing of streets and highways; traffic control activities of police or public safety agencies; and law enforcement and safety activities of vehicle inspection enforcement, and vehicle size and weight enforcement. State and local spending for transit is based on the National Transit Database (NTD) of the Federal Transit Administration (FTA). The NTD provides detailed financial and operating statistics for mass transit agencies in the United States. Data for railroads and pipeline are BTS estimates.
