Architecture Flow Definitions
alert notification (Existing) 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 (Existing) 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.
current infrastructure restrictions (Existing) Applicable ITS Standards
Restrictions levied on transportation asset usage based on infrastructure design, surveys, tests, or analyses. This includes standard facility design height, width, and weight restrictions, special restrictions such as spring weight restrictions, and temporary facility restrictions that are imposed during maintenance and construction.
emergency acknowledge (Existing) Applicable ITS Standards
Acknowledge request for emergency assistance and provide additional details regarding actions and verification requirements.
emergency notification (Existing) Applicable ITS Standards
An emergency request for assistance that is automatically initiated by a vehicle or manually initiated by a vehicle occupant. The request includes call–back number, date, time, location, pre–event vehicle heading, vehicle make, model, model year, and fuel type, and crash severity indicators. Crash severity indicators include: airbags deployed, number of impacts, crash delta velocity, principle direction of force, and rollover indication. In addition, seatbelt restraint use, number of occupants, occupant location, and intrusion may be included. For commercial vehicles, this flow may also include freight equipment type (box, flatbed, trailer, container, etc.), type of cargo (refrigerated, non–perishable, liquid, etc.), hazardous material data, quantity of cargo, and cargo permits as applicable (hazmat, special routing permissions).
equipment maintenance request (Existing) Applicable ITS Standards
Identification of field equipment requiring repair and known information about the associated faults.
equipment maintenance status (Existing) Applicable ITS Standards
Current status of field equipment maintenance actions.
evacuation information (Existing) Applicable ITS Standards
Evacuation instructions and information including evacuation zones, evacuation times, and reentry times.
external reports (Existing) Applicable ITS Standards
Traffic and incident information that is collected by the media through a variety of mechanisms (e.g., radio station call–in programs, air surveillance).
incident information for public (Existing) Applicable ITS Standards
Report of current desensitized incident information prepared for public dissemination.
maint and constr work plans (Existing) Applicable ITS Standards
Future construction and maintenance work schedules and activities including anticipated closures with anticipated impact to the roadway, alternate routes, anticipated delays, closure times, and durations.
road network conditions (Existing) 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 weather information (Existing) Applicable ITS Standards
Road conditions and weather information that are made available by road maintenance operations to other transportation system operators.
roadway maintenance status (Existing) Applicable ITS Standards
Summary of maintenance fleet operations affecting the road network. This includes the status of winter maintenance (snow plow schedule and current status).
traffic images (Existing) 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.
traffic information for media (Existing) Applicable ITS Standards
Report of traffic conditions including traffic incident reports for public dissemination through the media. The reports may also include information on diversions and alternate routes, closures, and special traffic restrictions in effect.
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.
work zone information (Existing) Applicable ITS Standards
Summary of maintenance and construction work zone activities affecting the road network including the nature of the maintenance or construction activity, location, impact to the roadway, expected time(s) and duration of impact, anticipated delays, alternate routes, and suggested speed limits. This information may be augmented with images that provide a visual indication of current work zone status and traffic impacts.
