Architecture Flow Definitions

automated lane control data  (Long-term)  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  (Long-term)  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.

barrier system control  (Long-term)  Applicable ITS Standards

Information used to configure and control barrier systems that are represented by gates, barriers and other automated or remotely controlled systems used to manage entry to roadways.

barrier system status  (Long-term)  Applicable ITS Standards

Current operating status of barrier systems. Barrier systems represent gates, barriers and other automated or remotely controlled systems used to manage entry to roadways. Status of the systems includes operating condition and current operational state.

environmental sensor data  (Existing)  Applicable ITS Standards

Current road conditions (e.g., surface temperature, subsurface temperature, moisture, icing, treatment status) and surface weather conditions (e.g., air temperature, wind speed, precipitation, visibility) as measured and reported by fixed and/or mobile environmental sensors. Operational status of the sensors is also included.

environmental sensors control  (Existing)  Applicable ITS Standards

Data used to configure and control environmental sensors.

lane management control  (Long-term)  Applicable ITS Standards

Information used to configure and control dynamic lane management systems.

lane management information  (Long-term)  Applicable ITS Standards

System status of managed lanes including current operational state, violations, and logged information. This includes lane usage information including both traditional traffic flow measures and special information associated with managed lanes such as measured passenger occupancies. It also includes the operational status of the lane management equipment.

right-of-way request notification  (Existing)  Applicable ITS Standards

Notice that a request has occurred for signal prioritization, signal preemption, pedestrian call, multi–modal crossing activation, or other source for right–of–way.

roadway dynamic signage data  (Existing)  Applicable ITS Standards

Information used to initialize, configure, and control dynamic message signs. This flow can provide message content and delivery attributes, local message store maintenance requests, control mode commands, status queries, and all other commands and associated parameters that support remote management of these systems.

roadway dynamic signage status  (Existing)  Applicable ITS Standards

Current operating status of dynamic message signs, highway advisory radios, or other configurable field equipment that provides dynamic information to the driver.

shoulder management control  (Long-term)  Applicable ITS Standards

Information used to configure and control systems that allow use of a shoulder as a lane for vehicular traffic.

shoulder management information  (Long-term)  Applicable ITS Standards

System status including current operational state, violations and logged information.

signal control commands  (Existing)  Applicable ITS Standards

Control of traffic signal controllers or field masters including clock synchronization.

signal control device configuration  (Existing)  Applicable ITS Standards
