Architecture Flow Definitions

conflict monitor status  (Future)  Applicable ITS Standards

A control flow that supports failsafe operation in the event that a conflict is detected that requires the RSE to enter a failsafe operating mode.

environmental sensor data  (Future)  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  (Future)  Applicable ITS Standards

Data used to configure and control environmental sensors.

roadway dynamic signage data  (Future)  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  (Future)  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.

vehicle signage local data  (Future)  Applicable ITS Standards

Information provided by adjacent field equipment to support in–vehicle signing of dynamic information that is currently being displayed to passing drivers. This includes the dynamic information (e.g., current signal states, grade crossing information, local traffic and road conditions, detours, advisories, parking availability, etc.) and control parameters that identify the desired timing, duration, and priority of the signage data.
