The ArrowBoard object describes an electronic, connected arrow board (example image) which can display an arrow pattern to direct traffic. Arrow boards are often placed at the beginning of a lane closure—thus knowing the location of an arrow board can assist in programmatically generating a WZDx road event with verified spatial information.
The ArrowBoard is a type of field device; it has a core_details property which contains the FieldDeviceCoreDetails and exists within a FieldDeviceFeature.
