Architecture Flow
Description
equipment availability
An inventory of the maintenance and construction equipment available at the
storage facility. This flow includes the type of equipment, enough descriptive
information to indicate its suitability for use, and its current status. This flow
may contain information for a specific type of equipment or include all
equipment available at the facility.
equipment maintenance status
Current status of field equipment maintenance actions.
evacuation coordination
Coordination of information regarding a pending or in-process evacuation.
Includes evacuation zones, evacuation times, evacuation routes, forecast
network conditions, and reentry times.
evacuation information
Evacuation instructions and information including evacuation zones,
evacuation times, and reentry times.
event plans
Plans for major events possibly impacting traffic.
external reports
Traffic and incident information that is collected by the media through a variety
of mechanisms (e.g., radio station call-in programs, air surveillance).
fare collection data
Fare collection information including the summary of on-board fare system
data and financial payment transaction data.
field device status
Reports from field equipment (sensors, signals, signs, controllers, etc.) which
indicate current operational status.
field equipment status
Identification of field equipment requiring repair and known information about
the associated faults.
freeway control data
Control commands and operating parameters for ramp meters, mainline
metering/lane controls and other systems associated with freeway operations.
freeway control status
Current operational status and operating parameters for ramp meters, mainline
metering/lane controls and other control equipment associated with freeway
operations.
hazmat information
Information about a particular hazmat load including nature of the load and
unloading instructions. May also include hazmat vehicle route and route
update information.
hazmat information request
Request for information about a particular hazmat load.
hazmat spill notification_ud
hri advisories
Notification of Highway-Rail Intersection equipment failure, intersection
blockage, or other condition requiring attention, and maintenance activities at
or near highway rail intersections.
hri control data
Data required for HRI information transmitted at railroad grade crossings and
within railroad operations.
hri operational status
Status of the highway-rail grade crossing equipment including both the current
state or mode of operation and the current equipment condition.
hri request
A request for highway-rail intersection status or a specific control request
intended to modify HRI operation.
hri status
Status of the highway-rail intersection equipment including both the current
state or mode of operation and the current equipment condition.
incident command information coordination
Information that supports local management of an incident. It includes
resource deployment status, hazardous material information, traffic, road, and
weather conditions, evacuation advice, and other information that enables
emergency or maintenance personnel in the field to implement an effective,
safe incident response.
incident information
Notification of existence of incident and expected severity, location, time and
nature of incident. As additional information is gathered and the incident
evolves, updated incident information is provided. Incidents include any event
that impacts transportation system operation ranging from routine incidents
(e.g., disabled vehicle at the side of the road) through large-scale natural or
human-caused disasters that involve loss of life, injuries, extensive property
damage, and multi-jurisdictional response. This also includes special events,
closures, and other planned events that may impact the transportation system.
incident information for media
Report of current desensitized incident information prepared for public
dissemination through the media.
incident report
Report of an identified incident including incident location, type, severity and
other information necessary to initiate an appropriate incident response.
