The WorkZoneFeed object is the root (highest level) object of a WZDx Work Zone Feed. There is one WorkZoneFeed object per WZDx GeoJSON document. The WorkZoneFeed is an instance of a GeoJSON FeatureCollection object.
The WorkZoneFeed contains high-level information about events occurring on roadways (called "road events") that impact the characteristics of the roadway and involve a change from the default state (such as a lane closure). The Work Zone Feed is the original work zone data exchange feed and was previously named WZDxFeed.
| Name | Type | Description | Conformance | Notes |
|---|---|---|---|---|
feed_info |
FeedInfo | Information about the WZDx Work Zone Feed. | Conditional; required if road_event_feed_info is not provided. |
This is a WZDx-specific foreign member and is not part of the GeoJSON specification. |
type |
String; "FeatureCollection" |
The GeoJSON object type. For WZDx, this must be the string FeatureCollection. |
Required | This is a GeoJSON property. |
features |
Array; [RoadEventFeature] | An array of GeoJSON Feature objects which represent WZDx road events. | Required | |
bbox |
GeoJSON Bounding Box | Information on the coordinate range for all RoadEventFeatures in the WZDx feed. Must be an array of length 2n where n is the number of dimensions represented in the contained geometries, with all axes of the most southwesterly point followed by all axes of the more northeasterly point. The axes order of a bbox follows the axes order of geometries. |
Optional | This is a GeoJSON property. |
road_event_feed_info (DEPRECATED) |
FeedInfo | This property is deprecated and will be removed in a future release, use the feed_info property instead — Information about the WZDx Work Zone Feed. |
Conditional; required if feed_info is not provided. |
This is a WZDx-specific foreign member and is not part of the GeoJSON specification. |
WZDx Work Zone Feed GeoJSON document (one WorkZoneFeed object per file).
