EM05-Transportation Infrastructure Protection (Service Package*)

Description

This service package includes the monitoring of transportation infrastructure (e.g., bridges, tunnels and management centers) for potential threats using sensors and surveillance equipment and barrier and safeguard systems to control access, preclude an incident, and mitigate the impact of an incident if it occurs. Threats can result from acts of nature (e.g., hurricanes, earthquakes), terrorist attacks or other incidents causing damage to the infrastructure (e.g., stray barge hitting a bridge support). Infrastructure may be monitored with acoustic, environmental threat (such as nuclear, biological, chemical, and explosives), infrastructure condition and integrity, motion and object sensors and video and audio surveillance equipment. Data from such sensors and surveillance equipment may be processed in the field or sent to a center for processing. The data enables operators at the center to detect and verify threats. When a threat is detected, agencies are notified. Detected threats or advisories received from other agencies result in an increased level of system preparedness. In response to threats, barrier and safeguard systems may be activated by Traffic Management Subsystems to deter an incident, control access to an area or mitigate the impact of an incident. Barrier systems include gates, barriers and other automated and remotely controlled systems that manage entry to transportation infrastructure. Safeguard systems include blast shields, exhaust systems and other automated and remotely controlled systems that mitigate impact of an incident.

The following discusses how the National ITS Architecture provides the transportation service described by this service package. Each numbered item describes the operation of that portion of the service package identified with the corresponding number on the transaction set diagram.

  1. The process of transportation infrastructure protection is under the asynchronous monitoring and control of the Emergency System Operator. The Emergency System Operator monitors (emergency operations status) and controls (emergency operations inputs) the sensor and surveillance equipment used to monitor transportation infrastructure.

  2. Physical and environmental characteristics such as visual, audible, chemical, biological, radiological, motion, and presence are monitored by surveillance and sensor systems (secure area characteristics). This equipment is located in areas frequented by travelers (Remote Traveler Support Subsystem, RTS) as well as areas typically away from travelers such as bridges, tunnels, etc. (Security Monitoring Subsystem, SMS).

  3. Environmental threat sensors (e.g., thermal, acoustic, radiological, chemical), object, motion and intrusion detection sensors are used to detect threats to transportation infrastructure. These sensors are located at the RTS or the SMS. The Emergency Management Subsystem (EM) monitors the sensor outputs, receiving either raw sensor outputs or outputs that have been processed at the RTS or SMS (secure area sensor data). The EM also controls (secure area sensor control) the sensors and preliminary processing that may occur in the field.

  4. Audio and video surveillance systems are used to monitor activity at and around transportation infrastructure. These systems can be located at the RTS or the SMS. The Emergency Management Subsystem monitors (secure area surveillance data) and controls (secure area surveillance control) the surveillance systems. The RTS or SMS systems may process the data prior to sending secure area surveillance data to the EM.

  5. Sensors located in the SMS are also used to monitor the condition or integrity of transportation infrastructure including bridges, tunnels, transit rail or guideways, etc. The Emergency Management Subsystem monitors the sensors (infrastructure monitoring sensor data) and controls (infrastructure monitoring sensor control) the sensors. The SMS sensors may process the data prior to sending infrastructure monitoring sensor data to the EM.

  6. The Emergency Management Subsystem collects and/or processes the infrastructure condition and integrity data and provides transportation system status to the Traffic Management, Transit Management, Maintenance and Construction Management Subsystems.

  7. The Maintenance and Construction Management Subsystem is responsible for maintenance and repair of the equipment used to monitor transportation infrastructure. The Emergency Management Subsystem notifies the Maintenance and Construction Management Subsystem of the current operation and fault status of the sensors or surveillance equipment (security field equipment status). When maintenance is performed, the Maintenance and Construction Management Subsystem notifies the Emergency Management Subsystem (security equipment maintenance status).

  8. In addition to the data collected from its own sensors and surveillance equipment, the Emergency Management Subsystem receives information on imminent or in-progress threats or emergencies (alerts and advisories) from Alerting and Advisory Systems. In response to alerts and advisories, the Emergency Management Subsystem may heighten protection of transportation infrastructure.

  9. The Emergency Management Subsystem coordinates and exchanges sensor and surveillance data and threat information (threat information coordination) and incident information (incident report) with Other Emergency Management systems.

  10. The Emergency Management Subsystem analyzes and correlates the sensor and surveillance data it has collected, as well as threat data, alerts and advisories from other agencies. Based on this information, it detects and verifies threats, and then notifies (threat information) the Traffic Management, Transit Management, Maintenance and Construction Management Subsystems and Rail Operations.

  11. In the event of a detected and verified threat to the transportation infrastructure, Emergency Management also notifies (threat information) Alerting and Advisory Systems. Emergency Management may send data from surveillance or sensor equipment (threat data for analysis) to Alerting and Advisory Systems for further analysis. Alerting and Advisory Systems may send additional information to assist Emergency Management Subsystem identify possible threats (threat support data).

  12. In response to a threat or a request (emergency traffic control request) from the Emergency Management Subsystem, barrier systems at the Roadway may be activated by Traffic Management Subsystems (barrier system control). Operational status of this equipment is monitored by the Traffic Management Subsystem (barrier system status). Barrier systems are operated under the command of the Traffic Systems Operator, which controls the systems (part of traffic operator inputs) and monitors the status of the equipment (part of traffic operator data). The barrier systems might also be operated by Emergency Vehicle Subsystem commands. The Traffic Management Subsystem notifies the Emergency Management Subsystem (emergency traffic control information) when the barrier systems have been deployed.

  13. When a closure is in effect, the barrier system may grant access to selected vehicles (e.g., responders, residents). Using Field-Vehicle Communications, the Vehicle requests and receives permission to access the restricted area (access request and access permission). The Driver may provide information that supports the access request (driver inputs) and receives information indicating whether access has been granted (driver updates).

  14. In response to a threat or a request (emergency traffic control request) from the Emergency Management Subsystem, safeguard systems such as blast shields and exhaust system at the Roadway may also be activated by Traffic Management Subsystems (safeguard system control). Operational status of this equipment is monitored by the Traffic Management Subsystem (safeguard system status). Safeguard systems are operated under the command of the Traffic Systems Operator, which controls the systems (part of traffic operator inputs) and monitors the status of the equipment (part of traffic operator data). The Traffic Management Subsystem notifies the Emergency Management Subsystem (emergency traffic control information) when the barrier systems and/or safeguard systems have been deployed.
