class py123d.datatypes.TrafficLightDetections

The TrafficLightDetections is a container for multiple traffic light detections. It provides methods to access individual detections as well as to retrieve a detection by lane id. The wrapper is used to read and write traffic light detections from/to logs.

Public Data Attributes:

detections	List of individual TrafficLightDetection.
timestamp	The Timestamp of the traffic light detections.
metadata	The metadata for the traffic light detections.

Inherited from BaseModality

timestamp	Returns the timestamp associated with this modality data, if available.
metadata	Returns the metadata associated with this modality data.
modality_type	Convenience property to access the modality type directly from the modality data.
modality_id	Convenience property to access the modality id directly from the modality data.
modality_key	Convenience property to access the modality key directly from the modality data.

Public Methods:

get_by_lane_id(lane_id)

Retrieve a traffic light detection by its lane id.
