Aviation Security: Improved Testing, Evaluation, and Performance Measurement Could Enhance Effectiveness
GAO-16-199T: Published: Nov 3, 2015. Publicly Released: Nov 3, 2015.
Evaluation of new technologies, programs, and processes . GAO has found that TSA has not consistently evaluated the overall effectiveness of new technologies before adopting them. For example, in March 2014, GAO found that TSA testing of certain Advanced Imaging Technology (AIT) systems—also referred to as full-body scanners—used to screen passengers at airports did not account for all factors...
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...
Pipeline Safety: Department of Transportation Needs to Complete Regulatory, Data, and Guidance Efforts
GAO-15-843T: Published: Sep 29, 2015. Publicly Released: Sep 29, 2015.
The Department of Transportation's (DOT) Pipeline and Hazardous Materials Safety Administration (PHMSA) has begun but not completed efforts to improve pipeline safety in response to GAO's prior recommendations:Gathering pipelines : In 2012, GAO found that while gathering pipelines that are not regulated by PHMSA were generally considered to present less safety risk than other pipelines, PHMSA did...
Public Transit: Updated Guidance and Expanded Federal Authority Could Facilitate Bus Procurement
GAO-15-676: Published: Sep 10, 2015. Publicly Released: Sep 24, 2015.
Overall, the number of manufacturers of transit buses has declined in recent years, but bus production has remained constant. Transit agencies purchase over 5,000 buses per year—about half are heavy-duty buses and half are smaller buses called “cutaways” because they consist of a bus body on top of a chassis built by another manufacturer. The number of firms that produce most heavy-duty tran...
Federal Aviation Administration: Commercial Space Launch Industry Developments Present Multiple Challenges
GAO-15-706: Published: Aug 25, 2015. Publicly Released: Sep 21, 2015.
During the last decade, U.S. companies conducted fewer orbital launches in total than companies in Russia or Europe, which are among their main foreign competitors. However, the U.S. commercial space launch industry has expanded recently. In 2014, U.S. companies conducted 11 orbital launches, compared with none in 2011. In addition, in 2014, U.S. companies conducted more orbital launches than comp...
Surface Transportation Security: TSA Has Taken Steps Designed to Develop Processes for Sharing and Analyzing Information and to Improve Rail Security Incident Reporting
GAO-15-205T: Published: Sep 17, 2015. Publicly Released: Sep 17, 2015.
In June 2014, GAO found that the Transportation Security Administration (TSA) did not have a systematic process for incorporating stakeholder feedback to improve security-related information sharing and recommended that TSA systematically document and incorporate stakeholder feedback. TSA concurred with this recommendation and, in April 2015, TSA developed a standard operating procedure to help en...
Positive Train Control: Additional Oversight Needed As Most Railroads Do Not Expect to Meet 2015 Implementation Deadline
GAO-15-739: Published: Sep 4, 2015. Publicly Released: Sep 16, 2015.
Most railroads in GAO’s review (20 of 29) estimate that they will implement positive train control (PTC)—a communications-based system designed to prevent certain types of train accidents—1 to 5 years after the statutory deadline of December 31, 2015 (3 did not have an estimated completion date). Of the remaining 6 railroads, one was excepted from installing PTC based on limited speeds on it...
General Aviation: Observations Related to Liability Insurance Requirements and Coverage for Aircraft Owners
GAO-15-740: Published: Sep 9, 2015. Publicly Released: Sep 9, 2015.
Based on GAO's 50-state survey of state aviation officials and analysis of state statutes and regulations identified by such officials, the vast majority of states do not have liability insurance requirements for general aviation (GA) aircraft owners and operators (i.e., pilots). As of April 2015, 11 states have some variation of a liability insurance requirement or aircraft financial-responsibili...
Next Generation Air Transportation System: Improved Risk Analysis Could Strengthen FAA's Global Interoperability Efforts
GAO-15-608: Published: Jul 29, 2015. Publicly Released: Aug 28, 2015.
Aviation industry stakeholders GAO interviewed described various factors that may affect the interoperability of the Next Generation Air Transportation System (NextGen)—a complex, long-term initiative to modernize the U.S. air-traffic management (ATM) system—with other countries' ATM modernization efforts. Interoperability allows different ATM systems and procedures to accept and use each othe...
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...
