Properties

Name	Type	Description
trip_id	number	The trip the event belongs to, where the source supplies one.
asset_id	number	The asset the event belongs to; today the `ASSET` anchor resolved from the payload's vehicle identifier.
position	object	The event position, carried as one value so it can never be half-populated.
device_id	number	The telematics unit that produced the event.
driver_id	number	The driver the event is attributed to, where the tenant's policy permits storing it.
speed_kmh	number	The peak speed recorded for the event.
duration_s	number	Duration of the overspeed event.
event_type	string	The source event-type label, where a tenant's feed mixes event types.
external_id	string	Source-system event identity, used for idempotent re-harvest and cross-chunk de-duplication.
occurred_at	string	When the overspeed event occurred, not when it was recorded.
recorded_at	string	When the telematics platform stamped/synchronised the event.
event_action	string	The TN360 action discriminator; the demo fixture carries `SE` for speed events.
source_units	object	The source unit per measure, where it is not the canonical unit.
location_label	string	A human-readable place name or address string for the event.
position_datum	string	The datum/CRS identifier the coordinate is in (e.g. the EPSG code), plus the source frame where known.
speed_offset_kmh	number	How far over the threshold the event was.
position_precision	string	Whether the coordinate is full precision or reduced (the US ELD personal-use mode is the worked example).
speed_threshold_kmh	number	The speed limit or threshold the event exceeded.
