My post #62 has links about TSA VIPR and Bus Safe.

From the Whitehouse, defining the role of TSA in regard to surface transportation. Some salient points from the PDF. I added the bold:

page 8
Sector-Specific Agency
(SSA)
 The Transportation Security Administration is the SSA for the security
of the land and air modes of the Transportation Systems Sector.


page 9, includes intercity buses specifically


Surface Transportation Modes
Mass transit, commuter and long-distance
passenger rail, freight rail, commercial
vehicles (including intercity buses), and
pipelines, and related infrastructure
(including roads and highways), that are
within the territory of the United States.
Executive Order 13416

The strategy guiding surface transportation security should focus on the following:
 Using intelligence to identify potential threats
 Employing programs and procedures that allow for better identification and interdiction
of threats prior to their arrival in the United States
 Engaging system operators in intelligence sharing, security planning, and operations
 Ensuring that key transportation workers are vetted
 Increasing frontline worker and public security awareness
 Creating a more stringent, less opportunistic environment for terrorist attack planning
(e.g., non-intrusive inspection devices, canine teams, random bag checks, VIPRs, and
counter-surveillance)
 Changing operations to reduce vulnerabilities and potential consequences and to thwart
attempts to circumvent security measures
 Hardening critical infrastructure (e.g., intrusion detection, facility hardening, smart
surveillance, and common operating picture development)
