Radioactive Sources: Opportunities Exist for Federal Agencies to Strengthen Transportation Security
GAO-17-58: Published: Feb 7, 2017. Publicly Released: Mar 9, 2017.
Since September 11, 2001, the three federal agencies responsible for securing risk-significant radioactive sources (those considered most dangerous) during ground transport have taken steps to strengthen the security of these sources. The Nuclear Regulatory Commission (NRC) requires source licensees to ensure that motor carriers transporting these sources have security measures, such as 24-hour mo...
School Bus Safety: Crash Data Trends and Federal and State Requirements
GAO-17-209: Published: Jan 12, 2017. Publicly Released: Jan 12, 2017.
Based on GAO's analysis of data for 2000 to 2014, 115 fatal crashes involved a school bus on average each year—which is 0.3 percent of the 34,835 total fatal motor-vehicle crashes on average each year. The school-bus driver and school-bus vehicle (e.g., a defect) were cited as contributing factors in 27 percent and less than 1 percent of fatal school-bus crashes, respectively. Seventy-two percen...
Hazardous Materials Rail Shipments: Emergency Responders Receive Support, but DOT Could Improve Oversight of Information Sharing
GAO-17-91: Published: Nov 17, 2016. Publicly Released: Nov 17, 2016.
Emergency planners from most of the 25 selected counties in 17 states that GAO surveyed reported that training for responders and information about rail shipments of hazardous materials affect preparedness. Emergency planners from almost all of the selected counties reported that a majority of the emergency response personnel, such as fire fighters, who arrive first at an accident receive basic tr...
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...
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 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...
