West Coast Ports: Better Supply Chain Information Could Improve DOT's Freight Efforts
GAO-17-23: Published: Oct 31, 2016. Publicly Released: Oct 31, 2016.
Some infrastructure and operations at major West Coast ports are strained in the face of recent changes in global shipping, but port stakeholders are attempting to address these constraints. For example, as the shipping industry deploys larger vessels capable of delivering more cargo, some port terminals lack big enough cranes, or other infrastructure, needed to handle these vessels. All major Wes...
Motor Carriers: Better Information Needed to Assess Effectiveness and Efficiency of Safety Interventions
GAO-17-49: Published: Oct 27, 2016. Publicly Released: Oct 27, 2016.
In July 2010, the Federal Motor Carrier Safety Administration (FMCSA) chose to delay nationwide implementation of two of the eight interventions that FMCSA uses to address motor carrier safety concerns under its Compliance, Safety, Accountability (CSA) program. This delay is linked to continuing delays in developing software needed to support the two interventions, offsite investigations and the u...
Train Braking: DOT's Rulemaking on Electronically Controlled Pneumatic Brakes Could Benefit from Additional Data and Transparency
GAO-17-122: Published: Oct 12, 2016. Publicly Released: Oct 12, 2016.
DOT based estimates of the business benefits of electronically controlled pneumatic (ECP) brakes on limited data, in part, because railroads that have used ECP brakes to date have shared limited data on their use. ECP brakes provide an electronic brake signal instantaneously throughout the train, allowing train cars to brake faster than with conventional air brakes. In supporting the May 2015 rule...
Federal Air Marshal Service: Additional Actions Needed to Ensure Air Marshals' Mission Readiness
GAO-16-764: Published: Sep 14, 2016. Publicly Released: Sep 14, 2016.
The Transportation Security Administration's (TSA) Office of Training and Development (OTD) assesses air marshals' training needs using several information sources, but opportunities exist to obtain more feedback from air marshals on whether the training courses they must take met their needs. OTD primarily assesses air marshals' training needs by holding curriculum development and review conferen...
Highway Bridges: Linking Funding to Conditions May Help Demonstrate Impact of Federal Investment
GAO-16-779: Published: Sep 14, 2016. Publicly Released: Sep 14, 2016.
Bridge conditions have generally improved nationwide from 2006 to 2015, based on GAO analysis of federal bridge data. For example, the percentage of structurally deficient bridge deck area (the surface area that carries vehicles) decreased from 9 percent to 7 percent nationwide during this period. The number of structurally deficient bridges also decreased from 13 percent to 10 percent nationwide...
Aviation Security: TSA Should Ensure Testing Data Are Complete and Fully Used to Improve Screener Training and Operations
GAO-16-704: Published: Sep 7, 2016. Publicly Released: Sep 7, 2016.
The Transportation Security Administration (TSA) uses a variety of programs to train and evaluate Transportation Security Officers (TSO) who are responsible for screening passengers and baggage for threats to aviation security. For example, by law, TSOs must complete 40 hours of classroom training, 60 hours of on-the-job training, and certification tests before performing screening. Once certified...
Aviation Safety: FAA's Risk-Based Oversight for Repair Stations Could Benefit from Additional Airline Data and Performance Metrics [Reissued on September 2, 2016]
GAO-16-679: Published: Jul 28, 2016. Publicly Released: Jul 28, 2016.
The extent to which U.S. airlines contract out aircraft maintenance to domestic and foreign repair stations (as opposed to performing maintenance in-house) has remained relatively steady from 2010 through 2014. GAO's analysis of Bureau of Transportation Statistics (BTS) data for that period (the most recent available) showed that 28 selected U.S. airlines' annual contracted maintenance spending ra...
Airport and Airway Trust Fund: Less Than Half of Noncommercial Jet Fuel Tax Receipts Are Transferred
GAO-16-746R: Published: Aug 8, 2016. Publicly Released: Aug 8, 2016.
The total number of potentially registerable vendors of jet fuel used in noncommercial aviation is unclear, but is likely greater than the number that have registered with the Internal Revenue Service (IRS) based on industry information. While registered vendors—called “ultimate vendors”—are eligible to receive credits or refunds for sales of such jet fuel, some ultimate vendors are not cl...
Inland Waterways Fuel Tax: Additional Data Could Enhance IRS's Efforts to Ensure Taxpayer Compliance
GAO-16-682: Published: Jul 29, 2016. Publicly Released: Jul 29, 2016.
Based on results of audits, the Internal Revenue Service (IRS) views vessel operators to be substantially in compliance with requirements to report and pay the Inland Waterways Fuel Tax (fuel tax). IRS seeks to ensure compliance by auditing quarterly excise-tax returns filed by these operators, as well as identifying operators that failed to file (nonfilers).Audits of filed returns: IRS data show...
Hazardous Materials Transportation: Better Guidance and Planning Could Enhance DOT's Explosives Classification Oversight
GAO-16-715: Published: Jul 28, 2016. Publicly Released: Jul 28, 2016.
The Department of Transportation's (DOT) Pipeline and Hazardous Materials Safety Administration's (PHMSA) oversight of the labs that issue classification recommendations for new explosives is limited by a lack of guidance, and stakeholders have mixed views on PHMSA's oversight. To receive a classification for a new explosive, manufacturers must have an approved test lab examine the explosive and s...
