Transportation-Disadvantaged Populations: Federal Coordination Efforts Could Be Further Strengthened
GAO-12-647: Published: Jun 20, 2012. Publicly Released: Jun 20, 2012.
Eighty federal programs are authorized to fund transportation services for the transportation disadvantaged, but transportation is not the primary mission of most of the programs GAO identified. Of these, the Department of Transportation administers 7 programs that support public transportation. The remaining 73 programs are administered by 7 other federal agencies and provide a variety of human s...
Delayed-Baggage Trends and Options for Compensating Passengers
GAO-12-804R: Published: Jun 14, 2012. Publicly Released: Jun 14, 2012.
In summary, we found that DOTs data do not distinguish between delayed baggage and other types of mishandled baggage, such as those that are lost, damaged, or pilfered. DOT includes all of these types of occurrences in its definition of mishandled baggage. Using DOTs data, we found that the number of mishandled-baggage reports has decreased since 2008, when airlines first b...
Intelligent Transportation Systems: Improved DOT Collaboration and Communication Could Enhance the Use of Technology to Manage Congestion
GAO-12-308: Published: Mar 19, 2012. Publicly Released: Apr 18, 2012.
State and local governments currently use ITS technologies in various ways to monitor and control traffic and inform travelers. For example, transportation agencies use cameras to monitor traffic conditions, signal technologies to control traffic flow, and dynamic message signs to inform travelers about travel conditions. By interviewing experts, GAO identified several emerging uses of ITS that ha...
Federal Advisory Groups: DOT and DOE Can Take Steps to Better Assess Duplication Risk and Enhance Usefulness
GAO-12-472: Published: Mar 29, 2012. Publicly Released: Mar 29, 2012.
Federal Advisory Committee Act (FACA) and Department of Transportation (DOT) and Department of Energy (DOE) guidance require officials to check for duplication prior to filing a charter to establish a new or renew an existing FACA advisory group. However, GAO found that DOT and DOEs processes for assessing duplication are often informal, and neither agency has specific steps identified for m...
Pipeline Safety:Collecting Data and Sharing Information on Federally Unregulated Gathering Pipelines Could Help Enhance Safety
GAO-12-388: Published: Mar 22, 2012. Publicly Released: Mar 22, 2012.
While the safety risks of onshore gathering pipelines that are not regulated by PHMSA are generally considered to be lower than for other types of pipelines, PHMSA does not collect comprehensive data to identify the safety risks of unregulated gathering pipelines. In response to a GAO survey, state pipeline safety agencies cited construction quality, maintenance practices, unknown or uncertain loc...
Aviation Safety: FAA Has An Opportunity to Enhance Safety and Improve Oversight of Initial Pilot Training
GAO-12-537T: Published: Mar 20, 2012. Publicly Released: Mar 20, 2012.
FAAs pilot training requirements for certification of commercial pilots are not aligned with airline operations or emphasize skills that airlines consider important for greater aviation safety.Requirements do not emphasize training in decision-making, although this skill is essential to the airline pilot profession. According to FAA and other stakeholders, the regulations regarding ground sc...
Air Traffic Control Modernization: Management Challenges Associated with Program Costs and Schedules Could Hinder NextGen Implementation
GAO-12-223: Published: Feb 16, 2012. Publicly Released: Feb 16, 2012.
In a review of 30 major ATC acquisition programs, all of which will contribute to the transition to NextGen, GAO found that costs for 11 of the 30 programs have increased from their initial estimates by a total of $4.2 billion and 15 programs experienced delays. The 11 acquisitions that experienced cost increases account for over 60 percent of FAAs total acquisition costs ($11 billion of $17.7 b...
Safety Effects of Less Prescriptive Requirements for Low-Stress Natural Gas Transmission Pipelines Are Uncertain
GAO-12-389R: Published: Feb 16, 2012. Publicly Released: Feb 16, 2012.
Applying PHMSAs new distribution integrity management requirements to low-stress transmission pipelines would result in less prescriptive safety requirements for these pipelines. Overall, requirements for distribution pipelines are less prescriptive than requirements for transmission pipelines in part because the former operate at lower pressure and pose lower risks in general than the latte...
Diesel Pollution: Fragmented Federal Programs That Reduce Mobile Source Emissions Could Be Improved
GAO-12-261: Published: Feb 7, 2012. Publicly Released: Feb 7, 2012.
Federal grant and loan funding for activities that reduce mobile source diesel emissions is fragmented across 14 programs at the Department of Energy (DOE), the Department of Transportation (DOT), and the Environmental Protection Agency (EPA). From fiscal years 2007 through 2011, the programs obligated at least $1.4 billion for activities that have the effect of reducing mobile source diesel emiss...
Traffic Congestion: Road Pricing Can Help Reduce Congestion, but Equity Concerns May Grow
GAO-12-119: Published: Jan 12, 2012. Publicly Released: Jan 20, 2012.
DOT approves all congestion pricing projects on roadways that receive federal funds and provides grants for project studies, implementation, and evaluation. Nearly all HOT lane projects and most peak-period pricing projects in operation today received federal funds at one time or another. DOTs largest programs for congestion relief, the Urban Partnership Agreement and Congestion Reduction De...
