Public Transit Security Information Sharing: DHS Could Improve Information Sharing through Streamlining and Increased Outreach, Report to Congressional Committees [open pdf - 4MB]
From the Highlights: "The Transportation Security Administration (TSA), in the Department of Homeland Security (DHS), is committed to sharing information with public transit agencies. The Implementing Recommendations of the 9/11 Commission Act directed GAO [Government Accountability Office] to report on public transit information sharing. This report describes (1) the primary mechanisms used to share security information with public transit agencies; and evaluates (2) public transit agencies' satisfaction with federal efforts to share security-related information (e.g., security threats) and opportunities to improve these efforts; and (3) the extent to which DHS has identified goals and measures for sharing information. GAO [Government Accountability Office] surveyed 96 of the 694 U.S. public transit agencies based on 2008 ridership and received 80 responses. The 96 public transit agencies surveyed represent about 91 percent of total 2008 ridership. GAO also reviewed documents, such as DHS's Information Sharing Strategy, and interviewed agency officials. […] GAO recommends that DHS, among other things, (1) establish time frames for its working group to develop options for improving information sharing, including assessing opportunities to streamline mechanisms and conducting targeted outreach; and (2) establish time frames for developing goals and outcome-oriented measures of results. DHS concurred. GAO is issuing an electronic supplement with this report--GAO-10-896SP--which provides survey results."
