Why GAO Did This Study: 

Mobility—that is, the movement of passengers and goods through the 
transportation system—is critical to the nation’s economic vitality and 
the quality of life of its citizens. However, increasing passenger 
travel and freight movement has led to growing congestion in the 
nation’s transportation system, and projections suggest that this trend 
is likely to continue. Increased congestion can have a number of 
negative economic and social effects, including wasting travelers’ time 
and money, impeding efficient movement of freight, and degrading air 
quality. U.S. transportation policy has generally addressed these 
negative economic and social effects from the standpoint of individual 
transportation modes and local government involvement. However, there 
has been an increased focus on the development of intermodal 
transportation. Intermodal transportation refers to a system that 
connects the separate transportation modes—such as mass transit 
systems, roads, aviation, maritime, and railroads—and allows a 
passenger to complete a journey using more than one mode. My testimony 
today is based on GAO’s prior work on intermodal transportation, 
especially intermodal ground connections to airports, and addresses (1) 
the challenges associated with developing and using intermodal 
capabilities and (2) potential strategies that could help public 
decision makers improve intermodal capabilities. 

What GAO Found: 

A number of financing, planning, and other challenges play significant 
roles in shaping transportation investment decisions and the 
development of intermodal capabilities. Significant challenges to the 
development of intermodal capabilities are the lack of specific 
national goals and funding programs. Federal funding is often tied to a 
single transportation mode; as a result it may be difficult to finance 
projects, such as intermodal projects, that do not have a source of 
dedicated funding. In addition, federally funded transportation 
projects, including intermodal projects, face a number of planning 
challenges. These challenges include limits on the uses of federal 
funds, ensuring that widespread public participation is reflected in 
decisions, physical and geographic land constraints, and the difficulty 
coordinating among multiple jurisdictions in transportation corridors. 
Finally, intermodal capabilities, while offering benefits to mobility, 
may need to develop a demand over time. 

Two general strategies developed from GAO’s prior work would help 
public decision makers improve intermodal capabilities. Both strategies 
are based on a systematic framework that includes identifying national 
goals, defining the federal role, determining funding approaches, and 
evaluating performance. The first strategy would increase the 
flexibility of current federal transportation programs to encourage a 
more systemwide approach to transportation planning and development, 
but would leave project selection with state and local decision makers. 
The second strategy is a fundamental shift in federal transportation 
policy’s focus on local decision making by increasing the role of the 
federal government in order to develop more integrated transportation 
networks. While the first strategy would most likely lead to a 
continued focus on locally determined and developed transportation 
projects, the second strategy could develop more integrated 
transportation networks, either nationwide or along particularly 
congested corridors. The second strategy could be costly, and high 
benefits, which may be difficult to achieve, would be needed to justify 
this investment.

Mr. Chairman and Members of the Subcommittee: 

Mobility--that is, the movement of passengers and goods through the 
transportation system--is critical to the nation's economic vitality 
and the quality of life of its citizens. Mobility provides people with 
access to goods, services, recreation, and jobs; 
provides businesses with access to material, markets, and people; 
and promotes the movement of personnel and material to meet national 
defense needs. However, increasing passenger and freight travel has led 
to growing congestion in the nation's transportation system, and 
projections of future passenger travel and freight movement suggest 
that this trend is likely to continue. For example, the number of 
airplane passengers using U.S. airports is expected to grow from over 
746 million in 2005 to almost 1 billion by 2015 and, since most 
travelers use cars, whether privately owned or taxis, to get to the 
airport, local cities and communities will face increased congestion on 
their airport access roads and highways. In addition, freight traffic 
on roadways has increased fourfold over the last two decades, and both 
rail and highway congestion are particularly severe in urban areas 
where ports for international trade are located. For example, in the 
Los Angeles area, freight traffic is projected to more than double 
along the two mainline freight railroads from 2003 to 2025. Increased 
congestion can have a number of negative economic and social effects, 
including wasting travelers' time and money, impeding efficient 
movement of freight, and degrading air quality. These effects are 
especially problematic in areas and transportation corridors that are 
already heavily congested. Such congestion may be relieved by 
intermodal transportation options-- that is a system that connects the 
separate transportation modes and allows a passenger or freight to 
complete a journey using more than one mode, such as bus, air, rail, 
and waterways. 

Our past work has shown that the development of intermodal capabilities 
can provide a range of benefits. Those benefits include potentially 
reduced travel times and costs for travelers and freight by providing 
alternative transportation options and eliminating freight 
"chokepoints" or bottlenecks at entrances to freight facilities, and 
reduced road congestion with the potential for an associated reduction 
in vehicle emissions and improved air quality. Intermodal 
transportation capabilities are typically initiated by state and local 
transportation agencies, including some combination of state 
departments of transportation, local transportation planning bodies 
(i.e., metropolitan planning organizations), airports, seaports, and 
local transit agencies. The federal government's role is primarily one 
of funding and oversight through separate transportation programs 
within the Department of Transportation (DOT). My testimony today is 
based on our prior work on intermodal transportation, and addresses (1) 
the challenges associated with developing and using intermodal 
capabilities and (2) potential strategies that could help public 
decision makers improve intermodal capabilities. In particular, I will 
be drawing a number of examples from our July 2005 report on ground 
access and intermodal connections at airports.[Footnote 1] (See Related 
GAO Products.) 

In summary: 

* Financing, planning, and other challenges play important roles in 
shaping transportation investment decisions and the development and use 
of intermodal capabilities. Significant challenges are the lack of 
specific national goals and funding programs to develop intermodal 
capabilities. Federal funding is often tied to a single transportation 
mode; as a result it may be difficult to finance projects, such as 
intermodal projects, that do not have a source of dedicated funding. 
This may also make it difficult to use federal funds to finance the 
best transportation investment, regardless of mode, to improve 
mobility. In addition, federal transportation projects, including 
intermodal projects, face a number of planning challenges that include 
limits on the uses of federal funds, ensuring that widespread public 
participation is reflected in decisions, physical and geographic land 
constraints, and the difficulty in coordinating among multiple 
jurisdictions in transportation corridors. Finally, intermodal 
capabilities, while offering benefits to mobility, may need to develop 
a demand over time. For example, in the case of ground access to 
airports, most passengers may prefer to use private vehicles to access 
airport over transit options. 

* Two general strategies could help public decision makers improve 
intermodal options. Both of these strategies are based on a systematic 
framework that includes identifying the federal interest in and 
national goals for transportation, defining the federal role, 
determining funding approaches, and evaluating performance. In the 
first strategy, Congress would increase flexibility within current 
federal transportation programs to encourage the development of 
intermodal capabilities and transportation investments that offer the 
best mobility improvements by shifting federal transportation funding, 
which is generally focused on individual transportation modes, to a 
more systemwide approach across all modes and types of travel. This 
strategy would include having the federal government develop approaches 
to target funding on transportation investments that better focus on 
outcomes related to national goals and promote better coordination 
between jurisdictions. The second strategy is a fundamental shift in 
federal transportation policy's long-time focus on state and local 
decisionmaking by increasing the role of the federal government in 
planning and funding intermodal projects in order to develop more 
integrated transportation networks, either nationwide or along 
particularly congested corridors. To develop a nationwide intermodal 
system, the federal government could take on a role similar to its 
efforts to develop the interstate highway system. A more active federal 
government role might also require additional federal funding 
responsibilities. For example, if the federal government were to take a 
more active role in developing airport intermodal capabilities that 
included enhancing or expanding rail service or developing high-speed 
rail corridors, it might also need to increase its funding role, and 
the role of other beneficiaries of the service, due to its high cost. 

Background: 

Historically, federal transportation policy has generally focused on 
individual modes rather than intermodal connections between different 
modes. Federal transportation funding programs are overseen by 
different modal offices within DOT--the Federal Aviation Administration 
(FAA), Federal Transit Administration (FTA), Federal Railroad 
Administration, and Federal Highway Administration (FHWA). No specific 
federal funding programs have been established that target intermodal 
projects for either passengers or freight although a few federal 
programs offer flexibilities that would allow these types of projects. 

Intermodal transportation refers to a system that connects the separate 
transportation modes--such as mass transit systems, roads, aviation, 
maritime, and railroads--and allows a passenger or freight to complete 
a journey using more than one mode. For example, an efficient 
intermodal capability at an airport would provide a passenger with 
convenient, seamless transfer between modes; the ability to connect to 
an extended transportation network; and high frequency of service among 
the different modes. As shown in figure 1, an intermodal connection at 
an airport might involve a passenger arriving at the airport by private 
shuttle service, flying to another airport, and then transferring to 
local rail service[Footnote 2] or a nationwide system, such as Amtrak, 
to reach a final destination. Similar to airline passengers, an 
intermodal freight transportation system relies on ready transport of 
cargo between ships and other transportation modes, particularly 
highway and rail.

Passenger:

[End of figure] 

The scope and nature of intermodal passenger connections is further 
illustrated by ground access to airports. In 2005, we reported that 
most major U.S. airports have direct intermodal ground connections to 
either local transportation systems or nationwide bus or rail 
networks.[Footnote 3] Sixty-four of the 72 airports[Footnote 4] that we 
surveyed reported having direct connections[Footnote 5] to one or more 
local transportation systems in their area, such as local bus or rail 
service, with 26 airports reporting having both. The most common type 
of public transportation system available to and from the airport is 
local bus service. Sixty-four airports reported having a direct 
connection to a local bus service. However, the level of bus service 
varies depending on the airport. For example, Seattle-Tacoma 
International Airport has five public bus routes that serve the 
surrounding communities, while General Mitchell International Airport 
in Milwaukee has only one route that serves the airport. Twenty-seven 
airports reported having a direct connection to a local rail system, 
such as light rail, commuter rail, or subway. (See fig. 2.) 

Figure 2: Major U.S. Airports with Direct Connections to Local Rail 
Systems:

[End of figure] 

While most major U.S. airports are located in metropolitan areas that 
have stations for nationwide transportation systems, such as Greyhound 
or Amtrak, 20 airports reported having direct connections to nationwide 
bus service or nationwide passenger rail service. Twelve of the 20 
airports reported having direct connections to nationwide bus service, 
and 14 airports reported having a direct connection to Amtrak rail 
service. (See fig. 3.) All 14 airports provide shuttle service to 
transport passengers to Amtrak stations that serve the metropolitan 
area. One of the 14 airports--Newark's Liberty International Airport-- 
reported that passengers could also access the Amtrak station by an 
automated people mover. In addition, the accessibility of Amtrak to 
Newark airport has allowed Continental Airlines to establish a code 
share agreement with Amtrak, whereby passengers can purchase one ticket 
for a journey that includes travel by both air and rail.[Footnote 6] 
This agreement has allowed Continental Airlines to eliminate some short-
haul flights from Newark.[Footnote 7]

Nationwide Rail Systems:

[End of figure] 

While there is no single federal funding source for rail to airport 
projects, we found that local governments, airports, and transit 
systems were able to tap and package a variety of federal funds to pay 
for recent rail connections to airports. These included direct 
appropriations, the New Starts program for fixed guideway transit 
systems, two federal aid highway categories--the Congestion Mitigation 
and Air Quality Improvement Program and the Surface Transportation 
Program--and passenger facility charges at airports. Appendix I 
describes these programs. 

Several Significant Challenges Affect the Development and Use of 
Intermodal Capabilities: 

According to transportation research, planning officials, and our prior 
work, a number of financing, planning, and other challenges play 
important roles in shaping transportation investment decisions and the 
development of intermodal capabilities. Significant challenges to the 
development of intermodal capabilities are the lack of specific 
national goals and funding programs. Federal funding is often tied to a 
single transportation mode; as a result it may be difficult to finance 
projects, such as intermodal projects, that do not have a source of 
dedicated funding. Federal legislation[Footnote 8] and federal planning 
guidance all emphasize the goal of establishing a systemwide, 
intermodal approach to addressing transportation needs. However, the 
reality of the federal funding structure--which directs most surface 
transportation spending to highways and transit and is more oriented to 
passengers than freight--plays an important role in shaping local 
transportation investment choices.[Footnote 9] In addition to the focus 
on highways and transit over other investment choices, we found limited 
instances in which investment decisions involved direct trade-offs in 
choices between modes or users--such as railroad versus highway or 
passenger versus freight.[Footnote 10] 

A significant challenge to developing certain intermodal connections is 
the difficulty of securing funding within the mode-specific federal 
funding structure. The cost of intermodal projects can vary widely, 
depending on the complexity and scope of the project. In addition, 
measuring and forecasting the benefits from individual projects can be 
hard to quantify, and we found only anecdotal evidence of benefits for 
the 16 intermodal projects we examined.[Footnote 11] The costs of rail 
projects are typically substantial and can include costs to construct a 
station, as well as track and other infrastructure to support the rail 
network. Table 1 provides examples of the costs of intermodal projects 
at airports and funding sources. We found that many intermodal projects 
at airports fit the funding criteria for one or more federal programs 
focused on surface transportation or aviation. For example, FTA's New 
Starts program is a significant source of funding for intermodal 
capabilities at airports that are part of a rail transit system. 
However, the rigorous rating process and increasing demands for its 
limited funds make the New Starts program time-intensive and 
competitive in nature and has made it difficult for local 
transportation agencies to secure this funding, according to local 
officials that we spoke with. Federal funding programs, like the New 
Starts program, will contribute only a portion of the total project 
costs, subject to local matching funds, which can be derived from local 
agencies such as metropolitan transportation authorities, transit 
agencies, and airport authorities.[Footnote 12] However, local 
transportation officials said it can be difficult to secure local funds 
for intermodal projects at airports because these agencies could 
potentially have different funding priorities, making it difficult to 
build the unified local support necessary to secure funding.

Additionally, intermodal capabilities at airports can be funded with 
passenger facility fees, commonly referred to as PFCs.[Footnote 13] 
Local transportation officials also described difficulties in securing 
the use of PFCs. In particular, requirements that PFC funds be used for 
projects on airport property, among other criteria, are seen as 
limiting their use for intermodal projects. Moreover, airlines support 
these restrictions on the use of PFC funds, believing that these funds 
are for airport development and capacity improvements, and not ground- 
access projects. However, even with this restriction, we reported in 
July 2005 that four airport authorities were using PFC funds to develop 
or contribute to intermodal projects at airports, as shown in table 2.

[End of table] 

In addition to the limits on the use of federal funds, federal 
transportation projects, including intermodal projects, face a number 
of planning challenges including the following: 

* Decision makers must ensure that wide-ranging public participation is 
reflected in their deliberations and that their choices take into 
account numerous views. During the planning of an intermodal project, 
the lead local agency's responsibilities include soliciting public 
comment regarding the most appropriate project to select for the area. 
This public participation can introduce considerations such as quality 
of life and other issues that are difficult to quantify in making 
transportation choices. It also puts decision makers in the position of 
balancing different public agendas about funding and values. 

* The physical constraints of an area may present a challenge to 
building intermodal facilities. The development of intermodal 
capabilities at airports provides an example of this challenge. On the 
one hand, our work has found that densely populated urban areas offer 
few alternatives for expansion or new project development. On the other 
hand, it is these same densely populated urban areas where rail 
connections to airports are more likely to generate benefits that will 
justify the costs, as these areas may have high levels of congestion 
and larger numbers of people willing to use public transportation to 
access airports as a result. For example, since the proposed light rail 
line into the Minneapolis/St. Paul International Airport crossed land 
owned by various federal agencies, the process to gain the needed right-
of-way was a multiagency effort that required significant coordination, 
adding somewhat to the project planning time and costs. 

* Multijurisdictional transportation corridors present special 
challenges in coordinating investment decisions. Getting the 
cooperation of and coordination between these different officials can 
make the planning and implementation of multistate and multiregional 
projects difficult. For example, during the planning of the Seattle 
light rail, Sound Transit officials noted that the alignment from 
downtown Seattle to the Seattle-Tacoma International Airport ran 
through a number of surrounding cities and required three local cities 
to approve permits for the construction of the project. 

The effective use of passenger rail as an intermodal option along 
heavily traveled air and highway corridors also poses challenges due to 
limitations of the existing nationwide rail network. For example, 
Amtrak's passenger rail network does not support air-rail service 
requirements because rail lines do not go near some airports, passenger 
train schedules in some parts of the country are not frequent enough to 
effectively link to airline flight schedules, and transferring from air 
to rail poses inconveniences that limit consumer demand. As we 
discussed previously, although 14 airports reported having a direct 
connection to Amtrak's passenger rail service, 1 reported that 
passengers could access the station by automated people movers--others 
required boarding a shuttle. In addition, although Amtrak track lines 
are adjacent to the Cleveland Hopkins International Airport, Amtrak 
officials stated that Amtrak trains run only twice a day along this 
line, which is not frequent enough to establish a code share agreement 
with an airline. 

Furthermore, transportation industry experts and European 
transportation officials have pointed out that high-speed passenger 
rail, including connections to congested airports, has provided an 
alternative for air travel in short-haul markets in Europe. There has 
been a reduction of air service between Paris, France, and Brussels, 
Belgium--a popular short distance city pair for travelers--due, in 
part, to the high-speed train service linking Paris Charles de Gaulle 
Airport and downtown Paris with Brussels. In the United States, few 
efforts have been made to use rail service to complement air service in 
this manner because, in part, the cost of establishing service is not 
likely to justify its benefits given that some distances are too great 
for rail to provide an attractive alternative transportation mode. 

Finally, intermodal capabilities, while offering benefits to mobility, 
may need to develop a demand over time. For example, the development 
and use of intermodal connections at airports can be limited by the 
inability of the ground connections to meet the preferences of airline 
passengers, therefore, the majority of passengers still use private 
vehicles to access airports even when transit service is available. 
Passenger preferences can include seamless transitions from one mode to 
another; a simplified process to handle baggage; transit schedules that 
meet consumer demands; and clear, easy-to-follow information on 
accessing transportation options--including signs at airports and 
information at hotels on accessing transit to airports. In addition, 
passengers, particularly those traveling with children and large 
amounts of luggage, may not consider using transit or rail systems to 
complete their travel plans due to inconvenience. 

Two General Strategies Could Help Address Intermodal Financing and 
Planning Challenges: 

Two general strategies could help public decision makers improve 
intermodal options. These strategies are based on a systematic 
framework that has the following three components: 

* Set national goals for the system. These goals, which would establish 
what federal participation in the system is designed to accomplish, 
should be specific and measurable. 

* Clearly define the federal role relative to the roles of state and 
local transportation agencies and the private sector. The federal 
government is one of many stakeholders involved in the development of 
intermodal capabilities. This component is important to help ensure 
that the federal role supplements and enhances the participation of 
other stakeholders and appropriately balances public investment when 
the benefits flow in part to the private sector. 

* Determine which funding approaches--such as alternatives to 
investment in new infrastructure and those approaches that reward 
projects that advance national/federal goals--will maximize the impact 
of any federal investment. This component can help expand the ability 
to leverage funding resources and promote shared responsibilities. 
Given the current budgetary environment, and the long-range fiscal 
challenges confronting the country, substantial increases in funding 
for transportation projects will require a high level of justification. 

In addition, either strategy would be enhanced by a process for 
evaluating performance periodically to determine if the anticipated 
benefits from federally-funded projects are accruing as expected. 

In the first strategy, Congress could encourage the development of 
intermodal capabilities by increasing the flexibility with current 
federal transportation programs, which are largely focused on 
individual transportation modes, to a more systemwide approach across 
all modes and types of travel. To promote intermodal development, the 
federal government could consider several alternatives for 
transportation planning and funding that might better focus on these 
outcomes and promote better coordination between jurisdictions. These 
alternatives include the following: 

* Increasing the flexibility of federal transportation funding programs 
to help break down the current funding stovepipes. 

* Applying different federal matching criteria for different types of 
expenditures in order to provide a higher level of federal matching for 
projects that reflect federal priorities. 

* Establishing performance-oriented funding or a reward-based system 
that would favor those entities that address the national interest and 
meet established intermodal goals. 

* Expanding support for alternative financing mechanisms--such as 
providing credit assistance to state and local governments for capital 
projects and using tax policy to provide incentives to the private 
sector for investing in intermodal capabilities--to access new sources 
of capital and stimulate additional investment in intermodal 
capabilities. 

* Aligning incentives for planning agencies to adopt best practices and 
to achieve expectations. 

While this strategy would involve changes in federal transportation 
policy, it would most likely not involve a major shift in the federal 
role, which would continue to be focused on funding and oversight of 
locally determined and developed transportation projects. However, 
since this strategy would include the goal of establishing a more 
systemwide approach to transportation planning, the federal government 
would need to determine the scope of its involvement in encouraging 
such an approach. 

The second strategy is a fundamental shift in federal transportation 
policy's long-time encouragement of state and local decision making by 
increasing the role of the federal government in planning and funding 
intermodal projects in order to develop more integrated intermodal 
networks, either nationwide or along particularly congested corridors. 
This strategy could be similar to the strategy the federal government 
used in the 1950s to develop the interstate highway system. Under this 
strategy, Congress could establish national goals for the development 
of intermodal capacities that could include not only the development of 
facilities and connections, but also the development of a supporting 
transportation network to improve the ability of either passengers or 
freight companies to reach their final destination. The role of the 
federal government would change, with the federal government taking a 
more active role in setting priorities and planning of intermodal 
connections between the individual transportation modes. Similar to the 
development of the interstate highway system, the federal government's 
role could include providing project specific oversight, laying out 
routes, overseeing construction, and ensuring that the system is 
adequately maintained. 

For the federal government to take a more active role in developing 
intermodal capabilities, it might also need to take on additional 
funding responsibilities. An example would be if a federal policy were 
established to develop a transportation system that promoted 
connections between airports and high-speed rail networks, as in 
Europe.[Footnote 14] To accomplish improved air-rail connections, the 
federal government would have to increase its funding role due to the 
high costs of enhancing or expanding rail service or developing high- 
speed rail corridors or tap others that would benefit from such 
service, including the region, its airport, and businesses associated 
with the airport as possible funding sources. The full costs of this 
policy would be dependent on how integrated and expansive such an 
intermodal network would be and whether it would include additional 
high-speed rail or be focused on conventional passenger rail service. 
We have shown in the past that both of these choices are costly and 
increased federal involvement could require the implementation of a 
dedicated funding source. 

However, even if a revenue source is established, this new funding 
would face many of the same revenue challenges that other 
transportation systems, such as highways, are facing now as revenues 
sources are eroded. Additionally, given the high costs of this 
strategy, benefits high enough to justify investment in intermodal 
facilities would likely be anticipated in a limited number of places. 

Concluding Observations: 

Increasing passenger travel and freight movement have led to growing 
congestion, and decision makers face the challenge of maintaining the 
nation's mobility while preventing congestion from overwhelming the 
transportation system. Successfully addressing mobility needs in the 
face of growing congestion requires both strategic and intermodal 
approaches. However, the current system for planning and financing 
transportation is not well-suited to advancing intermodal 
transportation projects--including both passenger and freight 
transportation--calling for fundamental changes that use a broader, 
systemwide approach to transportation investment decisions. A federal 
strategy of encouraging a more systemwide approach to transportation 
planning, including alternative funding mechanisms, could encourage 
transportation officials to consider the development of additional 
intermodal connections in the context of other transportation 
investment decisions. At the same time, it is clear that more 
quantitative evaluations of the costs and benefits of intermodal 
capabilities could help to better inform state and local, as well as 
federal decision makers, as they attempt to determine which projects to 
develop with their limited resources. 

Mr. Chairman, and members of the Subcommittee, this concludes my 
prepared statement. I would be pleased to answer any questions you or 
other members of the Subcommittee might have.

Appendix I: Federal Programs That Can Fund Intermodal Projects at 
Airports: 

Program: New Starts (FTA); 
Description: Selects worthy fixed guideway transit projects for funding 
by congressional appropriations. Projects can include heavy, light, and 
commuter rail and certain bus transit projects (such as bus rapid 
transit). To be eligible for funding, projects must, among other 
things, be justified based on a comprehensive review of mobility 
improvements, environmental benefits, cost effectiveness, and operating 
efficiencies, as well as being supported by an acceptable degree of 
local financial commitment. The program funding match is at most 80 
percent federal and 20 percent local.[A] In fiscal year 2006, this 
program was funded at $1.2 billion; 
Example of use at airports: Bay Area Rapid Transit extension south of 
the San Francisco International Airport into San Mateo County; 
New light rail system (Hiawatha Light Rail) providing service between 
downtown Minneapolis and the Mall of America, with two stations located 
at Minneapolis/St. Paul International Airport. 

Program: Congestion Mitigation and Air Quality Improvement Program 
(joint FHWA and FTA); 
Description: Funds transportation projects and programs in order to 
reduce transportation-related emissions in localities with poor air 
quality. To be eligible for funding, projects must be transportation 
related, in nonattainment or maintenance areas,[B] and reduce 
transportation-related emissions. The program funding match is 80 
percent federal and 20 percent local. In fiscal year 2006, this program 
was funded at $1.7 billion; 
Example of use at airports: Hiawatha Light Rail service between 
downtown Minneapolis and the Minneapolis/St. Paul International 
Airport. 

Program: Surface Transportation Program (FHWA); 
Description: Provides funding to states and localities for projects on 
any federal-aid highway--including transit capital projects and local 
and nationwide bus terminals and facilities. The program funding match 
is 80 percent federal and 20 percent local. In fiscal year 2006, this 
program was funded at $6.3 billion; 
Example of use at airports: Miami Intermodal Center at the Miami 
International Airport. 

Program: Transportation Infrastructure Finance and Innovation Act of 
1998 (joint FHWA/FTA); 
Description: Provides federal credit assistance for surface 
transportation projects. Project sponsors may include public, private, 
state, or local entities. Projects eligible for federal assistance 
through existing surface transportation programs, including passenger 
bus and rail facilities, are eligible for credit assistance under this 
program. The amount of federal credit assistance may not exceed 33 
percent of the reasonably anticipated project cost. In fiscal year 
2006, this program was funded at $130 million; 
Example of use at airports: Miami Intermodal Center at the Miami 
International Airport. 

Program: Airport Improvement Program (FAA); 
Description: Provides grants to airports for planning and development 
projects. The program is funded, in part, by aviation user excise 
taxes, which are deposited into the Airport and Airway Trust Fund. In 
terms of promoting intermodal capabilities, these funds may be used for 
access roads that are on airport property, airport owned, and 
exclusively serve airport traffic. The program funding match is 75 to 
90 percent federal based on the number of enplanements[C] at the 
airport and the remainder is from local sources. In fiscal year 2006, 
this program was funded at $3.5 billion; 
Example of use at airports: We found no example of its use for 
intermodal projects. 

Program: Passenger facility charges (FAA); 
Description: Authorizes commercial service airports to charge 
passengers a boarding fee-- commonly called a passenger facility 
charge--of up to $4.50, after obtaining FAA approval. The fees are used 
by the airports to fund FAA- approved projects that enhance safety, 
security, or capacity; reduce noise; or increase air carrier 
competition. In calendar year 2005, $2.4 billion in fees were collected 
under this program; 
Example of use at airports: AirTrain automated people mover at New 
York's John F. Kennedy International Airport and Newark's Liberty 
International Airport; 
Light rail extension and new station at Portland International Airport. 

Source: GAO analysis of DOT information. 

[A] When evaluating New Starts proposals, FTA places greater priority 
on projects that have a greater local matching share. Competitive New 
Starts proposals often have a 40-50 percent local match. 

[B] Federal air quality standards exist for certain common air 
pollutants (known as criteria pollutants). Geographic areas that have 
levels of a criteria pollutant above those allowed by the standards are 
called nonattainment areas. Areas that did not meet the standards for a 
criteria pollutant in the past but have reached attainment are known as 
maintenance areas. 

[C] An enplanement is defined as a passenger boarding a flight. 
Enplanements include passengers boarding the first flight of their 
trip, as well as passengers who board after connecting from another 
flight.

[2] Local transit rail includes commuter rail, light rail, subway 
systems, and trolleys.

[4] We surveyed all 68 large and medium hub U.S. airports, and those 
small hub airports (4 in total) that are located in the same 
metropolitan statistical area as one or more large or medium hub 
airports. 

[5] We considered a transfer point (such as a bus stop or rail station) 
to be a direct connection to the airport if (1) it was convenient for 
an average adult with luggage to walk to the transfer point from any of 
the airport's terminals; 
(2) the airport had an automated people mover that transports 
passengers from the transfer point to any of the airport's terminals; 
or (3) there was regular, fixed-route shuttle service from the transfer 
point to any of the airport's terminals. 

[6] Code sharing refers to the practice of airlines applying their own 
names and selling tickets to flights or rail service operation by other 
carriers. 

[7] Continental officials stated that in April 2003, they reinstated 
limited air service between Newark and Philadelphia because of market 
demand. 

[8] The Intermodal Surface Transportation Efficiency Act of 1991; 
the Transportation Equity Act for the 21st Century, enacted in 1998; 
and the Safe, Accountable, Flexible, Efficient Transportation Equity 
Act: A Legacy for Users, enacted in 2005. 

[9] While most federal funding sources and programs are linked to 
highway or transit uses, some funding flexibility between highway and 
transit is allowed under programs such as the National Highway System, 
Surface Transportation Program, and Congestion Mitigation and Air 
Quality Improvement Program. Federal programs provide limited support 
for investment in railroad infrastructure. 

[10] GAO, Surface Transportation: Many Factors Affect Investment 
Decisions, GAO-04-744 (Washington, D.C.: June 30, 2004). 

[11] Our case study airport locations were Baltimore-Washington 
International, General Mitchell International, John F. Kennedy 
International, La Guardia, Los Angeles International, Metropolitan 
Oakland International, Miami International, Minneapolis/St. Paul 
International, Newark Liberty International, Norman Y. Mineta San Jose 
International, Ontario International, Portland International, Ronald 
Reagan Washington National, San Francisco International, Seattle- 
Tacoma International, and Washington Dulles International. The airports 
were selected to provide a range of airport sizes (medium and large), 
planned or existing types of intermodal service, and geographic 
locations. 

[12] For selected New Starts projects, a maximum of 80 percent federal 
contribution to total project costs can be funded, but projects that 
request a maximum federal share of 60 percent of the project's total 
cost receive higher priority. 

[13] PFCs are fees up to $4.50 paid by airport passengers, which are 
used to finance airport capital improvements. 

[14] In several cases, European national governments have established 
policies to reduce the number of short-haul flights at their major 
airports and have supported these policies by funding high-speed rail 
infrastructure.
