What federal agency coordinates the sharing of intelligence on transportation threats?

The correct agency that coordinates the sharing of intelligence on transportation threats is the Department of Homeland Security (DHS). The DHS plays a crucial role in overseeing the overall security of the transportation system in the United States. This includes coordinating intelligence sharing among various federal, state, and local agencies to ensure a unified response to potential threats.

The DHS works closely with other organizations, such as the Transportation Security Administration (TSA) and the Federal Bureau of Investigation (FBI), to collect, analyze, and disseminate information regarding security threats to transportation systems. This collaborative approach is essential for maintaining the safety and security of air travel, rail systems, and other transportation modalities.

While the TSA is responsible for implementing security measures and protocols within the transportation sector and also plays a role in identifying threats, it is the DHS that coordinates the overall intelligence-sharing framework across various agencies. The Transportation Security Oversight Board (TSOB) does not exist as a prominent agency tasked with this specific function, and while the FBI has a critical role in dealing with national security threats, it operates more in a law enforcement capacity rather than in coordinating intelligence across the transportation sector.
