Mandated to screen all checked baggage using explosive detection systems at airports by December 31, 2003, the Transportation Security Administration (TSA) deployed two types of screening equipment: explosives detection systems (EDS), which use computer-aided tomography X-rays to recognize the characteristics of explosives, and explosives trace detection (ETD) systems, which use chemical analysis...
Federal-Aid Highways: FHWA Needs a Comprehensive Approach to Improving Project Oversight
GAO-05-173: Published: Jan 31, 2005. Publicly Released: Jan 31, 2005.
The federal-aid highway program provides over $25 billion a year to states for highway and bridge projects, often paying 80 percent of these projects' costs. The federal government provides funding for and oversees this program, while states largely choose and manage the projects. Ensuring that states effectively control the cost and schedule performance of these projects is essential to ensuring...
Highway And Transit Investments: Options for Improving Information on Projects' Benefits and Costs and Increasing Accountability for Results
GAO-05-172: Published: Jan 24, 2005. Publicly Released: Jan 24, 2005.
Mobility is critical to the nation's economy. Projections of future passenger and freight travel suggest that increased levels of investment may be needed to maintain the current levels of mobility provided by the nation's highway and transit systems. However, calls for greater investment in transportation come amid growing concerns about fiscal imbalances at all levels of the government. As a res...
Surface Transportation: Many Factors Affect Investment Decisions

Military Aircraft: DOD Needs to Determine Its Aerial Refueling Aircraft Requirements
GAO-04-349: Published: Jun 4, 2004. Publicly Released: Jun 4, 2004.
With the heavy pace of operations in support of the war on terrorism, the Department of Defense (DOD) and the Air Force have become increasingly concerned about their aging aerial refueling aircraft. We last reviewed the aerial refueling fleet in 1996 and found that KC-135 aircraft were aging and becoming increasingly costly to maintain and operate. In December 2001, we began new work on the Air F...
Comparison of States' Highway Construction Costs
GAO-04-113R: Published: Nov 3, 2003. Publicly Released: Dec 3, 2003.
We are reporting to Congress on whether Federal Highway Administration (FHWA) data can help transportation stakeholders understand how states' costs to build, reconstruct, and maintain federally financed highways, roads, and bridges (termed "constructing highways" for this report) compare. Durig our review, we became aware of significant issues regarding the quality of the data that FHWA collects...

In 2002, when major U.S. airlines posted net operating losses of almost $10 billion, they paid over $7 billion to distribute tickets to consumers. Of these total distribution expenses, airlines paid hundreds of millions of dollars in booking fees to global distribution systems--the companies who package airline flight schedule and fare information so that travel agents can query it to "book" (i.e...

Airport Finance: Past Funding Levels May Not Be Sufficient to Cover Airports' Planned Capital Development
GAO-03-497T: Published: Feb 25, 2003. Publicly Released: Feb 25, 2003.
Since Congress enacted the Wendell H. Ford Aviation Investment and Reform Act for the 21 Century (AIR-21) 3 years ago, much has changed. At that time, the focus was on reducing congestion and flight delays. Today, flights are being canceled for lack of business, two major air carriers are in bankruptcy, and attention has shifted from increasing the capacity of the national airspace system to enhan...
National Airspace System: Better Cost Data Could Improve FAA's Management of the Standard Terminal Automation Replacement System
