Architecture Flow Definitions

archive requests  (Existing)  Applicable ITS Standards

A request to a data source for information on available data (i.e., "catalog") or a request that defines the data to be archived. The request can be a general subscription intended to initiate a continuous or regular data stream or a specific request intended to initiate a one–time response from the recipient.

archive status  (Existing)  Applicable ITS Standards

Notification that data provided to an archive contains erroneous, missing, or suspicious data or verification that the data provided appears valid. If an error has been detected, the offending data and the nature of the potential problem are identified.

archived data product requests  (Existing)  Applicable ITS Standards

A user–specified request for archived data products (i.e., data, meta data, or data catalogs). The request also includes information that is used to identify and authenticate the user and support electronic payment requirements, if any.

archived data products  (Existing)  Applicable ITS Standards

Raw or processed data, meta data, data catalogs and other data products provided to a user system upon request. The response may also include any associated transaction information.

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.

device control request  (Existing)  

Request for device control action

device data  (Existing)  

Data from detectors, environmental sensor stations, roadside equipment, and traffic control devices, including device inventory information.

device status  (Existing)  

Status information from devices

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.

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.

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.

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.

work plan feedback  (Existing)  Applicable ITS Standards

Comments and suggested changes to proposed construction and maintenance work schedules and activities. This information influences work plan schedules so that they minimize impact to other system operations and the overall transportation system.

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.
