Architecture Flow Description
secure area sensor control Information used to configure and control threat sensors (e.g., thermal,
acoustic, radiological, chemical), object, motion and intrusion detection
sensors. The provided information controls sensor data collection,
aggregation, filtering, and other local processing.
secure area sensor data Data provided by threat sensors (e.g., thermal, acoustic, radiological,
chemical), and intrusion, motion, and object detection sensors in secure areas
indicating the sensor's operational status, raw and processed sensor data, and
alarm indicators when a threat has been detected.
secure area surveillance control Information used to configure and control audio and video surveillance
systems used for transportation infrastructure security in secure areas. The
provided information controls surveillance data collection, aggregation,
filtering, and other local processing.
secure area surveillance data Data collected from surveillance systems used to monitor secure areas.
Includes video, audio, processed surveillance data, equipment operational
status, and alarm indicators when a threat has been detected.
security field equipment status Identification of security sensors and surveillance equipment requiring repair
and known information about the associated faults.
selected routes Routes selected based on route request criteria.
short range communications status Status of the short range communications equipment including the current
state or mode of operation and the current equipment status.
signal control data Information used to configure and control traffic signal systems.
signal control status Status of surface street signal controls including operating condition and
current operational state.
speed monitoring control Information used to configure and control automated speed monitoring, speed
warning, and speed enforcement systems.
speed monitoring information System status including current operational state and logged information
including measured speeds, warning messages displayed, and violation
records.
storage facility request Request for information about the equipment and/or materials available at a
maintenance storage facility.
suggested route Suggested route for a dispatched emergency or maintenance vehicle that may
reflect current network conditions and the additional routing options available
to en route emergency or maintenance vehicles that are not available to the
general public.
tag data Unique tag ID and related vehicle information.
tag update Data written to a tag to support electronic toll collection or parking payment.
threat information Threats regarding transportation infrastructure, facilities, or systems detected
by a variety of methods (sensors, surveillance, threat analysis of advisories
from outside agencies, etc.
threat information coordination Sensor, surveillance, and threat data including raw and processed data that is
collected by sensor and surveillance equipment located in secure areas.
toll instructions Information provided to configure and support toll plaza operations including
toll pricing information.
toll transactions Detailed list of transactions from a toll station.
track status Current status of the wayside equipment and notification of an arriving train.
traffic archive data Information describing the use and vehicle composition on transportation
facilities and the traffic control strategies employed. Content may include a
catalog of available information, the actual information to be archived, and
associated meta data that describes the archived information.
traffic control coordination Information transfers that enable remote monitoring and control of traffic
management devices. This flow is intended to allow cooperative access to,
and control of, field equipment during incidents and special events and during
day-to-day operations. This flow also allows 24-hour centers to monitor and
control assets of other centers during off-hours, allows system redundancies
and fail-over capabilities to be established, and otherwise enables integrated
traffic control strategies in a region.
traffic control priority request Request for signal priority at one or more intersections along a particular route.
traffic control priority status Status of signal priority request functions at the roadside (e.g. enabled or
disabled).
