WorkZoneRoadEvent Object

The WorkZoneRoadEvent object describes a work zone road event including where, when, and what activities are taking place within a work zone on a roadway. A full "work zone" is represented by one or more WorkZoneRoadEvents.

The WorkZoneRoadEvent is a type of road event; it has a core_details property which contains the RoadEventCoreDetails and exists within a RoadEventFeature.

Properties

Name Type Description Conformance Notes
core_details RoadEventCoreDetails The core details of the road event that are shared by all types of road events, not specific to work zones. Required Please see Business Rule #1.
start_date String; date-time The UTC time and date when the event begins. Required All datetime formats shall follow RFC 3339 Section 5.6. Example: 2016-11-03T19:37:00Z.
Please see Business Rule #5.
end_date String; date-time The UTC time and date when the event ends. Required All datetime formats shall follow RFC 3339 Section 5.6. Example: 2016-11-03T19:37:00Z.
Please see Business Rule #5.
is_start_date_verified Boolean Indicates if work has been confirmed to have started, such as from a person or field device. Conditional; required if start_date_accuracy is not provided.
is_end_date_verified Boolean Indicates if work has been confirmed to have ended, such as from a person or field device. Conditional; required if end_date_accuracy is not provided.
is_start_position_verified Boolean Indicates if the start position (first geometric coordinate pair) is based on actual reported data from a GPS-equipped device that measured the location of the start of the work zone. Conditional; required if beginning_accuracy is not provided.
is_end_position_verified Boolean Indicates if the end position (last geometric coordinate pair) is based on actual reported data from a GPS-equipped device that measured the location of the end of the work zone. Conditional; required if ending_accuracy is not provided.
work_zone_type WorkZoneType The type of work zone road event, such as if the road event is static or actively moving as part of a moving operation. Optional
location_method LocationMethod The typical method used to locate the beginning and end of a work zone impact area. Required
vehicle_impact VehicleImpact The impact to vehicular lanes along a single road in a single direction. Required
impacted_cds_curb_zones Array; [CdsCurbZonesReference] A list of references to external CDS Curb Zones impacted by the work zone. Optional
lanes Array; [Lane] A list of individual lanes within a road event (roadway segment). Optional Please see Business Rules #1 and #2.
beginning_cross_street String Name or number of the nearest cross street along the roadway where the event begins. Optional
ending_cross_street String Name or number of the nearest cross street along the roadway where the event ends. Optional
beginning_milepost Number The linear distance measured against a milepost marker along a roadway where the event begins. Optional A milepost or mile marker is a surveyed distance posted along a roadway measuring the length (in miles or tenth of a mile) from the south west to the north east. These markers are typically notated on State and local government digital road networks.
ending_milepost Number The linear distance measured against a milepost marker along a roadway where the event ends. Optional A milepost or mile marker is a surveyed distance posted along a roadway measuring the length (in miles or tenth of a mile) from the south west to the north east. These markers are typically notated on State and local government digital road networks.
types_of_work Array; [TypeOfWork] A list of the types of work being done in a road event and an indication of if each type results in an architectural change to the roadway. Optional
worker_presence WorkerPresence Information about whether workers are present in the road event area. Optional
reduced_speed_limit_kph Number The reduced speed limit posted within the road event, in kilometers per hour. This property only needs to be supplied if the speed limit within the road event is lower than the posted speed limit of the roadway. Optional
restrictions Array; [Restriction] A list of zero or more road restrictions that apply to the roadway segment described by this road event. Optional Restrictions can also be provided on an individual lane.
event_status (DEPRECATED) EventStatus This property is deprecated and will be removed in a future release The status of the event. Optional
start_date_accuracy (DEPRECATED) TimeVerification This property is deprecated and will be removed in a future release, use is_start_date_verified instead A measure of how accurate the start date-time is. Conditional; required if is_start_date_verified is not provided.
end_date_accuracy (DEPRECATED) TimeVerification This property is deprecated and will be removed in a future release, use is_end_date_verified instead A measure of how accurate the end date-time is. Conditional; required if is_end_date_verified is not provided.
beginning_accuracy (DEPRECATED) SpatialVerification This property is deprecated and will be removed in a future version, use is_start_position_verified instead. Indicates how the beginning coordinate was defined. Conditional; required if is_start_position_verified is not provided.
ending_accuracy (DEPRECATED) SpatialVerification This property is deprecated and will be removed in a future version, use is_end_position_verified instead. Indicates how the ending coordinate was defined. Conditional; required if is_end_position_verified is not provided.
