field equipment status for METR

This flow provides reports from field equipment (sensors, signals, signs, controllers, etc.) indicating current operational status. Certain METR rules and corresponding physical rules will rely on the supporting data provided by field equipment. For example, a roadside sensor can be used to detect precipitation, which might be defined to activate a rule for a lower speed limit. This infrastructure-sourced supporting data can be provided to a CV RSE and then transmitted to METR user systems so that they can become aware of current status of rules.
