Architecture Flow Definitions
alert notification (Planned) Applicable ITS Standards
Notification of a major emergency such as a natural or man–made disaster, civil emergency, or child abduction for distribution to the public. The flow identifies the alert originator, the nature of the emergency, the geographic area affected by the emergency, the effective time period, and information and instructions necessary for the public to respond to the alert. This flow may also identify specific information that should not be released to the public.
alert notification coordination (Planned) Applicable ITS Standards
Coordination of emergency alerts to be distributed to the public. This includes notification of a major emergency such as a natural or man–made disaster, civil emergency, or child abduction for distribution to the public and status of the public notification.
alert status (Planned) Applicable ITS Standards
Information indicating the current status of the emergency alert including identification of the traveler and driver information systems that are being used to provide the alert.
data query publication (Planned) Applicable ITS Standards
Data query publication includes those dialogs necessary to satisfy the response portion of a query–response action using the data distribution architecture. The information content varies widely based on available content and the query, but it generally includes information on the state of transportation system operations including traffic and road conditions, advisories, incidents, transit service information, weather information, parking information, and other related data.
emergency traffic control information (Planned) Applicable ITS Standards
Status of a special traffic control strategy or system activation implemented in response to an emergency traffic control request, a request for emergency access routes, a request for evacuation, a request to activate closure systems, a request to employ driver information systems to support public safety objectives, or other special requests. Identifies the selected traffic control strategy and system control status.
evacuation coordination (Planned) Applicable ITS Standards
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 (Planned) Applicable ITS Standards
Evacuation instructions and information including evacuation zones, evacuation times, and reentry times.
incident command information coordination (Planned) Applicable ITS Standards
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 report (Planned) Applicable ITS Standards
Report of an identified incident including incident location, type, severity and other information necessary to initiate an appropriate incident response.
incident response coordination (Planned) Applicable ITS Standards
Incident response procedures and current incident response status that are shared between allied response agencies to support a coordinated response to incidents. This flow provides current situation information, including a summary of incident status and its impact on the transportation system and other infrastructure, and current and planned response activities. This flow also coordinates a positive hand off of responsibility for all or part of an incident response between agencies.
incident response status (Planned) Applicable ITS Standards
Status of the current incident response including a summary of incident status and its impact on the transportation system, traffic management strategies implemented at the site (e.g., closures, diversions, traffic signal control overrides), and current and planned response activities.
logged vehicle routes (Planned) Applicable ITS Standards
Anticipated route information for guided vehicles, special vehicles (e.g., oversize vehicles) or groups of vehicles (e.g., governor's motorcade) that may require changes in traffic control strategy.
resource coordination (Planned) Applicable ITS Standards
Coordination of resource inventory information, specific resource status information, resource prioritization and reallocation between jurisdictions, and specific requests for resources and responses that service those requests.
resource deployment status (Planned) Applicable ITS Standards
Status of resource deployment identifying the resources (vehicles, equipment, materials, and personnel) available and their current status. General resource inventory information and specific status of deployed resources may be included.
resource request (Planned) Applicable ITS Standards
A request for resources to implement special traffic control measures, assist in clean up, verify an incident, etc. The request may poll for resource availability or request pre–staging, staging, or immediate deployment of resources. Resources may be explicitly requested or a service may be requested and the specific resource deployment may be determined by the responding agency.
road network status assessment (Planned) Applicable ITS Standards
Assessment of damage sustained by the road network including location and extent of the damage, estimate of remaining capacity, required closures, alternate routes, necessary restrictions, and time frame for repair and recovery.
threat information (Planned) Applicable ITS Standards
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 (Planned) Applicable ITS Standards
Sensor, surveillance, and threat data including raw and processed data that is collected by sensor and surveillance equipment located in secure areas.
transportation system status (Planned) Applicable ITS Standards
Current status and condition of transportation infrastructure (e.g., tunnels, bridges, interchanges, TMC offices, maintenance facilities). In case of disaster or major incident, this flow provides an assessment of damage sustained by the surface transportation system including location and extent of the damage, estimate of remaining capacity and necessary restrictions, and time frame for repair and recovery.
