The Department of Homeland Security’s Science and Technology Directorate and the Transportation Security Administration (TSA) research, develop, and test technologies to address threats to mass transit systems.

In particular, TSA tests the effectiveness of commercially available technologies that could help secure mass transit systems, and produces written assessments of these products. However, TSA does not routinely or comprehensively share its assessments with the mass transit operators.

We recommended that it do so to better inform these operators about the capabilities of technology they may buy to secure their systems.

What GAO Found

The Department of Homeland Security's (DHS) Science and Technology Directorate (S&T) has one research and development (R&D) effort focused on surface transportation, the Surface Transportation Explosive Threat Detection (STETD) program, which is developing technologies to secure mass transit systems (see figure). DHS guidance requires S&T to develop results-oriented milestones to track progress. GAO found, however, that S&T has not used milestones that fully adhered to DHS guidance. For example, most STETD program milestones did not clearly link to key activities described in program plans. As a result, DHS may not have the information needed to determine whether the STETD program is meeting its goals.

S&T, TSA, and stakeholders effectively collaborate, but TSA could better share test results with mass transit stakeholders. For example, S&T, TSA, and mass transit operators regularly collaborate on issues related to identifying mass transit capability gaps and testing security technologies to address those gaps. Nevertheless, GAO found TSA's efforts to share information on existing technologies to secure mass transit could be improved. Specifically, TSA regularly assesses commercially available technologies, but does not routinely or comprehensively share its results with mass transit operators. For example, TSA's reports on its testing of commercially available products would provide mass transit operators with technical assessment information. However, seven of the nine mass transit operators GAO spoke with asked for more technical assessment information on existing commercial technologies, indicating that they may not be receiving the TSA products that would provide this information. Sharing this information more routinely and comprehensively with mass transit operators would allow TSA to better inform them about the capabilities of technologies that could be acquired to secure thteir systems.

Why GAO Did This Study

Since 2016, bombings of subways and bus systems in foreign cities and attempted attacks in U.S. cities demonstrate continued security threats to mass transit and other surface transportation systems. S&T and TSA are the primary federal entities responsible for researching, developing, and testing technologies designed to address threats to these systems. GAO has previously identified challenges with S&T's oversight of R&D projects.

GAO was asked to review S&T and TSA's roles in developing and testing surface transportation security technologies. This report, among other objectives, (1) assesses the extent to which S&T is developing technologies to secure surface transportation systems and progress made, and (2) identifies the key mechanisms that S&T, TSA, and stakeholders use to collaborate and share information on identifying capability gaps and security technologies, and analyzes the extent to which they are effective.

GAO assessed S&T's mass transit program because it was the only active R&D effort for surface transportation security. GAO interviewed officials from S&T, TSA, and nine mass transit operators; observed technologies; reviewed documentation; and analyzed budget information from fiscal years 2013 to 2018. GAO also used GAO's leading collaboration practices to assess collaboration on security technologies.

What GAO Recommends

GAO is making two recommendations: that S&T incorporate DHS milestone guidance for its STETD program, and that TSA develop a mechanism to routinely and comprehensively share security technology information with mass transit operators. DHS concurred with both recommendations.

Recommendations for Executive Action

  1. Status: Open

    Comments: In September 2019, GAO reported on a Department of Homeland Security's (DHS) Science and Technology Directorate (S&T) research and development (R&D) program to develop technologies to secure mass transit systems. DHS budget guidance requires S&T to develop results-oriented milestones to track program progress. GAO found that the S&T program's milestones did not clearly link to key activities described in program plans, and thus, were not results oriented. Therefore, we recommended that DHS develop milestones to track its progress developing the technologies that fully adhered to guidance. DHS concurred with our recommendation, and in February 2020, reported that S&T's Finance and Budget Division validated that milestones for the program were compliant with DHS guidance. GAO is currently working with DHS S&T to review documentation related to the validation process in order to close the recommendation..

    Recommendation: The Deputy Secretary of Homeland Security should ensure that S&T take steps to more fully incorporate practices for developing milestones within DHS's budget preparation guidance, into the Surface Transportation Explosive Threat Detection program. (Recommendation 1)

    Agency Affected: Department of Homeland Security

  2. Status: Open

    Comments: In September 2019, GAO reported on key mechanisms that TSA uses to collaborate and share information on identifying capability gaps and security technologies with stakeholders, including mass transit operators. We found that TSA regularly assesses commercially available technologies, but does not routinely or comprehensively share its results with mass transit operators. Therefore, we recommended that TSA develop a mechanism to routinely and comprehensively share security technology information with mass transit operators. TSA concurred with our recommendation, and in February 2020, reported implementing two of three planned efforts to better share security technology information, including steps to increase distribution of its annual publication on security technologies and to provide regular updates on assessed technologies at routine stakeholder meetings. We will continue to monitor TSA efforts with a third effort in order to close this recommendation.

    Recommendation: The Administrator of TSA should develop a mechanism to more routinely and comprehensively share appropriate information on the performance of mass transit security technologies (such as the annual sensor catalog and security technology assessments) with mass transit operators and stakeholders until DHS completes work on a more permanent information sharing resource. (Recommendation 2)

    Agency Affected: Department of Homeland Security: Transportation Security Administration
