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  (Planned)  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  (Planned)  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  (Planned)  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.

emergency traveler information  (Existing)  

Public notification of an emergency such as a natural or man–made disaster, civil emergency, or child abduction. This flow also includes evacuation information including evacuation instructions, evacuation zones, recommended evacuation times, tailored evacuation routes and destinations, traffic and road conditions along the evacuation routes, traveler services and shelter information, and reentry times and instructions.

incident information for public  (Existing)  Applicable ITS Standards

Report of current desensitized incident information prepared for public dissemination.

maint and constr archive data  (Planned)  Applicable ITS Standards

Information describing road construction and maintenance activities identifying the type of activity, the work performed, and work zone information including work zone configuration and safety (e.g., a record of intrusions and vehicle speeds) information. For construction activities, this information also includes a description of the completed infrastructure, including as–built plans as applicable. Content may include a catalog of available information, the actual information to be archived, and associated meta data that describes the archived information.

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 archive data  (Planned)  Applicable ITS Standards

Information describing the use and vehicle composition on transportation facilities and the traffic control strategies employed. Content may include a catalog of available information, the actual information to be archived, and associated meta data that describes the archived information.

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.

transit service information  (Existing)  

Transit service information including routes, schedules, and fare information as well as dynamic transit schedule adherence and transit vehicle location information.

traveler archive data  (Planned)  Applicable ITS Standards

Data associated with traveler information services including service requests, facility usage, rideshare, routing, and traveler payment transaction data. Content may include a catalog of available information, the actual information to be archived, and associated meta data that describes the archived information.

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.
