The federal government spent about 75 percent of the total amount budgeted for information technology (IT) for fiscal year 2015 on operations and maintenance (O&M) investments. Such spending has increased over the past 7 fiscal years, which has resulted in a $7.3 billion decline from fiscal years 2010 to 2017 in development, modernization, and enhancement activities.Total Federal IT Spending by Ty...
Vehicle Cybersecurity: DOT and Industry Have Efforts Under Way, but DOT Needs to Define Its Role in Responding to a Real-world Attack
GAO-16-350: Published: Mar 24, 2016. Publicly Released: Apr 25, 2016.
Modern vehicles contain multiple interfaces—connections between the vehicle and external networks—that leave vehicle systems, including safety-critical systems, such as braking and steering, vulnerable to cyberattacks. Researchers have shown that these interfaces—if not properly secured—can be exploited through direct, physical access to a vehicle, as well as remotely through short-range a...
Federal Aviation Administration: Preliminary Observations of Potential Air Traffic Control Restructuring Transition Issues
GAO-16-386R: Published: Feb 10, 2016. Publicly Released: Feb 10, 2016.
Based on our literature review and preliminary discussions with experts, several transition issues would need to be addressed if the U.S. air traffic control (ATC) system were to be restructured, including transition issues related to determining the funding and finance structure of the new entity, transferring assets, separating the safety regulator from the ATC entity, mitigating potential impac...
U.S. Border Communities: Ongoing DOT Efforts Could Help Address Impacts of International Freight Rail
GAO-16-274: Published: Jan 28, 2016. Publicly Released: Jan 28, 2016.
Factors such as inspections and crew changes affect freight rail movements in the four U.S. border port of entry (POE) communities GAO visited, which can result in blocked highway-rail grade crossings. Federal agencies and others have taken actions to expedite rail in these communities. As part of its mission to safeguard the border, U.S. Customs and Border Protection (CBP) scans inbound rail cars...
Federal Acquisitions: Use of 'Other Transaction' Agreements Limited and Mostly for Research and Development Activities
GAO-16-209: Published: Jan 7, 2016. Publicly Released: Jan 7, 2016.
Congress has authorized 11 federal agencies to use other transaction agreements—which generally do not follow a standard format or include terms and conditions required in traditional mechanisms, such as contracts or grants—to help meet project requirements and mission needs. The National Aeronautics and Space Administration (NASA) first received this authority in 1958. Over the next several d...
Air Travel and Communicable Diseases: Comprehensive Federal Plan Needed for U.S. Aviation System's Preparedness
GAO-16-127: Published: Dec 16, 2015. Publicly Released: Dec 16, 2015.
All of the 14 airports and 3 airlines GAO reviewed have plans for responding to communicable disease threats from abroad, although the United States lacks a comprehensive national aviation-preparedness plan aimed at preventing and containing the spread of diseases through air travel. U.S. airports and airlines are not required to have individual preparedness plans, and no federal agency tracks whi...
Defense Transportation: DOD Needs to Improve the Evaluation of Safety and Performance Information for Carriers Transporting Security-Sensitive Materials
GAO-16-82: Published: Dec 10, 2015. Publicly Released: Dec 10, 2015.
The Department of Defense's (DOD) use of the Department of Transportation's (DOT) safety performance information does not fully result in sufficient and reliable information to evaluate the safety performance of individual commercial motor carriers that transport security-sensitive materials under the Transportation Protective Service (TPS) program. DOT uses data from roadside inspections, crash i...

Cyclists represented 1.7 percent of all United States traffic deaths in 2004, but 2.3 percent in 2013. Estimates of pedestrian and cyclist injuries also gre...
Intelligent Transportation Systems: Vehicle-to-Infrastructure Technologies Expected to Offer Benefits, but Deployment Challenges Exist
GAO-15-775: Published: Sep 15, 2015. Publicly Released: Oct 15, 2015.
Vehicle-to-infrastructure (V2I) technologies allow roadside devices to communicate with vehicles and warn drivers of safety issues; however, these technologies are still developing. According to the Department of Transportation (DOT), extensive deployment may occur over the next few decades. DOT, state, and local-transportation agencies; researchers; and private-sector stakeholders are developing...
Vehicle Safety Inspections: Improved DOT Communication Could Better Inform State Programs
GAO-15-705: Published: Aug 25, 2015. Publicly Released: Aug 25, 2015.
According to officials GAO interviewed from 15 state vehicle safety inspection programs, these programs enhance vehicle safety; however, the benefits and costs of such programs are difficult to quantify. State officials told GAO that inspections help identify vehicles with safety problems and result in repair or removal of unsafe vehicles from the roads. For example, Pennsylvania state data show t...
