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...
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...
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...
