TrafficSensor Object

The TrafficSensor object describes a traffic sensor deployed on a roadway which captures traffic metrics (e.g. speed, volume, occupancy) over a collection interval. The TrafficSensor can describe lane-level traffic data if available and if associated with a road event (e.g. WorkZoneRoadEvent).

The TrafficSensor is a type of field device; it has a core_details property which contains the FieldDeviceCoreDetails and exists within a FieldDeviceFeature.

Properties

Name Type Description Conformance Notes
core_details FieldDeviceCoreDetails The core details of the field device shared by all field devices types, not specific to traffic sensors. Required This property appears on all field devices.
collection_interval_start_date String; date-time The UTC date and time where the TrafficSensor data began being collected at. The averages and totals contained in the TrafficSensor data apply to the inclusive interval of collection_interval_start_date to collection_interval_end_date. Required All datetime formats shall follow RFC 3339 Section 5.6. Example: 2016-11-03T19:37:00Z.
Please see Business Rule #5.
collection_interval_end_date String; date-time The UTC date and time where the TrafficSensor collection interval ended. The averages and totals contained in the TrafficSensor data apply to the inclusive interval of collection_interval_start_date to collection_interval_end_date. Required All datetime formats shall follow RFC 3339 Section 5.6. Example: 2016-11-03T19:37:00Z.
Please see Business Rule #5.
average_speed_kph Number (>= 0) The average speed of vehicles across all lanes over the collection interval in kilometers per hour. Optional
volume_vph Number (>= 0) The rate of vehicles passing by the sensor during the collection interval in vehicles per hour. Optional
occupancy_percent Number (>= 0) The percent of time the roadway section monitored by the sensor was occupied by a vehicle over the collection interval. Optional
lane_data Array; [TrafficSensorLaneData] A list of objects each describing traffic data for a specific lane. Optional
