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 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 provision  (Existing)  Applicable ITS Standards

Data provision provides the source material for a publish–subscribe or query–retrieval data distribution scheme. This is the 1 of the 1:N data distribution architecture. This flow is a super–flow; it does not define data elements but is inclusive of any flow implemented using publish–subscribe or query–retrieval methods.

data publication  (Existing)  Applicable ITS Standards

Data publication includes those dialogs necessary to satisfy the publication portion of a data distribution architecture. The information content varies widely based on available content and the subscription, 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.

data query  (Existing)  Applicable ITS Standards

Data query includes those dialogs necessary to determine what data is available for and also submit a query for near–term response.

data query publication  (Existing)  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.

data subscription  (Existing)  Applicable ITS Standards

Data subscription includes those dialogs necessary to determine what data is available for subscription/query, and also the dialogs necessary to create or modify data subscriptions/queries.

emergency plan coordination  (Existing)  Applicable ITS Standards

Information that supports coordination of emergency management plans, continuity of operations plans, emergency response and recovery plans, evacuation plans, and other emergency plans between agencies. This includes general plans that are coordinated prior to an incident and shorter duration tactical plans that are prepared during an incident.

emergency route request  (Planned)  Applicable ITS Standards

Request for access routes for emergency response vehicles and equipment. This may be a request for ingress or egress routes or other emergency routes.

emergency routes  (Planned)  Applicable ITS Standards

Suggested ingress and egress routes for access to and between the scene and staging areas or other specialized emergency access routes.

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.

emergency traffic control request  (Planned)  Applicable ITS Standards

Special request to preempt the current traffic control strategy in effect at one or more signalized intersections or highway segments, activate traffic control and closure systems such as gates and barriers, activate safeguard systems, or use driver information systems. For example, this flow can request all signals to red–flash, request a progression of traffic control preemptions along an emergency vehicle route, request a specific evacuation traffic control plan, request activation of a road closure barrier system, or place a public safety or emergency–related message on a dynamic message sign.

evacuation information  (Existing)  Applicable ITS Standards

Evacuation instructions and information including evacuation zones, evacuation times, and reentry times.

incident information  (Existing)  Applicable ITS Standards

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 public  (Existing)  Applicable ITS Standards

Report of current desensitized incident information prepared for public dissemination.

incident response status  (Existing)  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.

remote surveillance control  (Existing)  Applicable ITS Standards

The control commands used to remotely operate another center's sensors or surveillance equipment so that roadside surveillance assets can be shared by more than one agency.

resource deployment status  (Existing)  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  (Existing)  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 conditions  (Planned)  Applicable ITS Standards

Current and forecasted traffic information, road and weather conditions, and other road network status. Either raw data, processed data, or some combination of both may be provided by this flow. Information on diversions and alternate routes, closures, and special traffic restrictions (lane/shoulder use, weight restrictions, width restrictions, HOV requirements) in effect is included.

road network status assessment  (Existing)  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.

traffic images  (Planned)  Applicable ITS Standards

High fidelity, real–time traffic images suitable for surveillance monitoring by the operator or for use in machine vision applications. This flow includes the images and meta data that describes the images.

transportation system status  (Existing)  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.
