Architecture Flow Definitions
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.
electric charging services inventory (Planned) Applicable ITS Standards
Aggregate information provided for electric charging stations identifying the location, operating hours, current availability, charging capacity and standards supported, access restrictions, and rates/fee structure for each station.
electric charging station information (Planned) Applicable ITS Standards
Information provided for electric charging stations identifying the location, operating hours, current availability, charging capacity and standards supported, access restrictions, and rates/fee structure.
equipment control commands (Planned) Applicable ITS Standards
System–level control commands issued to the RSE such as reset and remote diagnostics.
field equipment commands (Planned) Applicable ITS Standards
System–level control commands issued to field equipment such as reset and remote diagnostics.
field equipment configuration settings (Planned) Applicable ITS Standards
Control settings and parameters that are used to configure field equipment.
field equipment software install/upgrade (Planned) Applicable ITS Standards
This flow supports installation and update of software residing in ITS roadway equipment. It supports download of the software installation files, including executable code and associated support files.
field equipment status (Planned) Applicable ITS Standards
Reports from field equipment (sensors, signals, signs, controllers, etc.) which indicate current operational status.
intersection geometry (Planned) Applicable ITS Standards
The physical geometry of an intersection covering the location and width of each approaching lane, egress lane, and valid paths between approaches and egresses. This flow also defines the location of stop lines, cross walks, specific traffic law restrictions for the intersection (e.g., turning movement restrictions), and other elements that support calculation of a safe and legal vehicle path through the intersection.
local traveler information (Existing) Applicable ITS Standards
Traveler information including traffic, road, and weather conditions for a particular locality. This flow includes the location–specific traveler information and time effectivity of the information.
location correction (Planned) Applicable ITS Standards
Information provided to improve positional accuracy. These corrections allow a mobile GPS receiver, such as a GPS system in a connected vehicle, to achieve a
greater absolute positional accuracy, compensating for errors that exist in satellite positioning.
personal location (Planned) Applicable ITS Standards
The current location (latitude, longitude, and elevation) reported by the personal information device
personal safety warning (Planned) Applicable ITS Standards
Safety alerts and warnings provided to a personal information device. The provided information would identify safety threats (e.g., vehicle encroachment into a work area, personal infringement into a travel lane)
RSE application information (Planned) Applicable ITS Standards
RSE application configuration data and parameters that are used to control applications and configure the application for a specific local use. This flow also supports remote control of the application so the application can be taken offline, reset, or restarted.
RSE application install/upgrade (Planned) Applicable ITS Standards
This flow supports remote installation and update of software applications residing in the RSE. It supports transmission of the secure software installation files, including executable application code and associated support files.
RSE application status (Planned) Applicable ITS Standards
Monitoring of RSE application status including current mode, operational status, and configuration settings. It includes the status of installed applications and the application–specific data provided by the RSE.
traveler information application info (Existing) Applicable ITS Standards
Traveler information and associated parameters, filters, and thresholds that control the RSE's distribution of the traveler information to passing vehicles. This flow also supports remote control of the application so the application can be taken offline, reset, or restarted.
traveler information application status (Existing) Applicable ITS Standards
Application status reported by the RSE. This includes current operational state and status of the RSE and a record of traveler information distribution.
