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...
Vehicle Safety: Enhanced Project Management of New Information Technology Could Help Improve NHTSA's Oversight of Safety Defects
GAO-16-312: Published: Feb 24, 2016. Publicly Released: Mar 24, 2016.
The National Highway Traffic Safety Administration (NHTSA) faces several challenges in its oversight of vehicle safety defects and has initiated or proposed some actions to address them. Challenges include improving data collection and analysis, providing adequate guidance and standard business processes to the staff who identify and investigate potential vehicle defects, and keeping pace with new...
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...
Pedestrians and Cyclists: Cities, States, and DOT Are Implementing Actions to Improve Safety
GAO-16-66: Published: Nov 19, 2015. Publicly Released: Dec 10, 2015.
Pedestrian and cyclist fatalities and injuries represent a growing percentage of all traffic fatalities and injuries. For example, pedestrian fatalities comprised 10.9 percent of all traffic deaths nationwide in 2004, but 14.5 percent in 2013. 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...
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...
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...
