A traffic sign.

All coordinates and orientations are relative to the global ground truth coordinate system.

Definition of the variability of a traffic sign.

Enumerator
VARIABILITY_UNKNOWN	Variability type of sign is unknown (must not be used in ground truth).
VARIABILITY_OTHER	Other (unspecified but known) variability.
VARIABILITY_FIXED	Sign that can change neither semantically nor positionally, e.g. a fixed, immutable, non-temporary traffic sign.
VARIABILITY_VARIABLE	Sign that can change semantically and/or positionally, i.e. it is left unspecified in which way the sign may change. Note This value represents a legacy definition. If possible, please use the more specific values below to indicate the exact nature of variability.
VARIABILITY_MOVABLE	Sign that can change positionally but not semantically, e.g. a temporary, immutable traffic sign at construction site.
VARIABILITY_MUTABLE	Sign that can change semantically but not positionally, e.g. a digital traffic sign on traffic sign gantry, or an analog prism sign.
VARIABILITY_MOVABLE_AND_MUTABLE	Sign that can change both semantically and positionally, e.g. a temporary, digital traffic sign at a construction site, or a digital traffic sign attached to a road works vehicle.

optional Identifier osi3::TrafficSign::id = 1

The ID of the traffic sign.

optional MainSign osi3::TrafficSign::main_sign = 2

Main sign, e.g.

speed limit 30 km/h

repeated SupplementarySign osi3::TrafficSign::supplementary_sign = 3

Additional supplementary signs, e.g.

time limits, modifying the traffic sign.

repeated ExternalReference osi3::TrafficSign::source_reference = 4

Optional external reference to the traffic sign source.

The external reference point to the source of the traffic sign, if it is derived from one or more objects or external references.

For example, to reference a signal defined in an OpenDRIVE map the items should be set as follows:

reference = URI to map, can remain empty if identical with definition in GroundTruth::map_reference
type = "net.asam.opendrive"
identifier[0] = id of t_road_signals_signal

Note: For non-ASAM Standards, it is implementation-specific how source_reference is resolved.; If an individual identification of MainSign and SupplementarySign is necessary, this should be done via multiple individual entries of this source_reference.; The value has to be repeated, because one lane segment may be derived from more than one origin segment. Multiple sources may be added as reference as well, for example, a map and sensors.
