Released February 2023
New Functionality
- Define the RoadIncidentFeed and IncidentRoadEvent to enable providing a feed of crashes, natural disasters, special events, and weather.
- Add vehicle_impact property to the RestrictionRoadEvent
- Incorporate changes made to the Work Zone Data Exchange (WZDx) Specification versions 4.1 and 4.2 adding new functionality to objects and enumerated types:
- Recommend using Universally Unique Identifiers (UUID) for the id property of the RoadEventFeature and FeedDataSource, noting that a UUID may be required in the next major release.
- Add name property to RoadEventCoreDetails to allow providing a human-friendly name for a road event.
- Add a related_road_events property (and new supporting object RelatedRoadEvent and enumerated type RelatedRoadEventType) to the RoadEventCoreDetails to allow explicitly defining relationships/connections between road events; this replaces the Relationship object concept.
- Add the following values to the Direction enumerated type: inner-loop, outer-loop, undefined, and unknown.
- Add no-passing to the RestrictionType enumerated type.
- Add two-way-center-turn-lane to the LaneType enumerated type to replace the existing center-left-turn-lane with a more generic value.
Refactoring
- Incorporate changes made to the WZDx Specification deprecating objects, properties, and enumerated type values utilized in this specification:
- Deprecate the relationship property on the RoadEventCoreDetails; use the new related_road_events property instead.
- Deprecate the center-left-turn-lane value in the LaneType enumerated type; use the new two-way-center-turn-lane instead.
Cleanup
- Incorporate changes made to WZDx Specification cleaning up objects and values utilized in this specification:
- Expand the description of the geometry property on the RoadEventFeature object to clarify how geometry should be used to represent a road event.
- Update the description of the open and closed enumerations of the LaneStatus enumerated type.
