Architecture Flow Definitions

data collection and monitoring control  (Existing)  Applicable ITS Standards

Information used to configure and control data collection and monitoring systems.

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.

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.

local situation data  (Existing)  Applicable ITS Standards

This general flow represents the traffic, environmental, and emissions situation data that is collected from connected vehicles by an RSE, aggregated, filtered, and provided to a back–office center. It also includes data collected from ITS roadway equipment that provides current intersection and road network status for the area proximate to the RSE.

roadside archive data  (Existing)  Applicable ITS Standards

A broad set of data derived from roadside sensors that includes current traffic conditions, environmental conditions, and any other data that can be directly collected by roadside sensors. This data also indicates the status of the sensors and reports of any identified sensor faults.

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.
