Architecture Flow Definitions
automated lane control data (Future) Applicable ITS Standards
Control commands and operating parameters provided to RSEs that control and monitor automated vehicle operations, including tightly coupled platooned groups of vehicles operating in dedicated or mixed–mode lanes. This flow includes platoon parameters including maximum platoon size, target speeds and gaps, and vehicle restrictions.
automated lane status (Future) Applicable ITS Standards
Current operational status of lanes supporting automated vehicle operations. The flow includes the status of the RSEs, associated field equipment, and vehicles using the facility.
environmental monitoring application info (Future) Applicable ITS Standards
Environmental monitoring application parameters and thresholds that control the filtering, aggregation, and range of measures that are collected, derived, and reported. This flow also supports remote control of the application so the application can be taken offline, reset, or restarted.
environmental monitoring application status (Future) Applicable ITS Standards
Environmental monitoring application status reported by the RSE. This includes current operational state and status of the RSE and a record of system operation.
environmental situation data (Future) Applicable ITS Standards
Aggregated and filtered vehicle environmental data collected from vehicle safety and convenience systems including measured air temperature, exterior light status, wiper status, sun sensor status, rain sensor status, traction control status, anti–lock brake status, and other collected vehicle system status and sensor information. This information flow represents the aggregated and filtered environmental data sets that are provided by the RSE to the back office center. Depending on the RSE configuration and implementation, the data set may also include environmental sensor station data collected by the RSE.
intersection management application info (Future) Applicable ITS Standards
Intersection and device configuration data, including intersection geometry, and warning parameters and thresholds. This flow also supports remote control of the application so the application can be taken offline, reset, or restarted.
intersection management application status (Future) Applicable ITS Standards
Infrastructure application status reported by the RSE. This includes current operational state and status of the RSE and a log of operations.
intersection safety application info (Future) Applicable ITS Standards
Intersection and device configuration data, including intersection geometry, and warning parameters and thresholds. This flow also supports remote control of the application so the application can be taken offline, reset, or restarted.
intersection safety application status (Future) Applicable ITS Standards
Infrastructure safety application status reported by the RSE. This includes current operational state and status of the RSE and a record of intersection safety issues identified and alerts and warnings issued.
queue warning application information (Future) Applicable ITS Standards
Information regarding formed or impending queues (location of the end of queue, estimated duration of the queue, and other descriptions of the queue condition) and recommendations for upstream vehicles including speed reduction, lane change, or diversion recommendations. This flow also supports remote control of the application so the application can be taken offline, reset, or restarted.
queue warning application status (Future) Applicable ITS Standards
Queue warning application status reported by the RSE. This includes current operational state and status of the RSE and a record of measured vehicle speeds and identified queues.
restricted lanes application info (Future) Applicable ITS Standards
Restricted lane application configuration data and messaging parameters. This flow defines the location, duration, and operating parameters for lanes that are reserved for the exclusive use of certain types of vehicles (e.g., transit vehicles) or vehicles that meet other qualifications (e.g., number of occupants, low emissions criteria). It identifies the lane(s), the start and stop locations, start and end times, vehicle restrictions, speed limits and platooning parameters. This flow also supports remote control of the application so the application can be taken offline, reset, or restarted.
restricted lanes application status (Future) Applicable ITS Standards
Current RSE application status that is monitored by the back office center including the operational state of the RSE, current configuration parameters, and a log of lane use (aggregate profiles of vehicles that checked in to the lane and reported vehicle speeds in the lanes) and RSE communications activity.
situation data collection parameters (Future) Applicable ITS Standards
The parameters that are used to control the flow of situation data from the RSE. This flow identifies the type of data/snapshots that are requested from passing vehicles and reporting parameters such as snapshot frequency, filtering criteria (data thresholds for reporting), and reporting interval that control the type and volume of data reported to the back office center.
speed management application information (Future) Applicable ITS Standards
Current speed targets, advisories, and limits including time of day, week, or season speed limits as necessary, and application parameters and thresholds. This flow also supports remote control of the application so the application can be taken offline, reset, or restarted.
speed management application status (Future) Applicable ITS Standards
Speed management application status reported by the RSE. This includes current operational state and status of the RSE and a record of measured vehicle speeds and current speed targets, advisories, and limits.
traffic monitoring application info (Future) Applicable ITS Standards
Traffic monitoring application parameters and thresholds that control the filtering, aggregation, and range of measures that are collected, derived, and reported. This flow also supports remote control of the application so the application can be taken offline, reset, or restarted.
traffic monitoring application status (Future) Applicable ITS Standards
Traffic monitoring application status reported by the RSE. This includes current operational state and status of the RSE and a record of system operation.
traffic situation data (Future) Applicable ITS Standards
Current, aggregate traffic data collected from connected vehicles that can be used to supplement or replace information collected by roadside traffic detectors. It includes raw and/or processed reported vehicle speeds, counts, and other derived measures. Raw and/or filtered vehicle control events may also be included to support incident detection.
vehicle signage application info (Future) Applicable ITS Standards
In–vehicle signing application configuration data and messaging parameters. This flow provides a list of regulatory, warning, and information messages to be displayed and parameters that support scheduling and prioritizing messages to be issued to passing vehicles. This flow also supports remote control of the application so the application can be taken offline, reset, or restarted.
vehicle signage application status (Future) Applicable ITS Standards
In–vehicle signing application status reported by the RSE. This includes current operational state and status of the RSE and a log of messages sent to passing vehicles.
