The RoadEventFeature
object is the container object for a WZDx road event (WorkZoneRoadEvent or DetourRoadEvent. The RoadEventFeature
object is an instance of a GeoJSON Feature.
Name | Type | Description | Conformance | Notes |
---|---|---|---|---|
id |
String | A unique identifier issued by the data feed provider to identify the WZDx road event. It is recommended that this identifier is a Universally Unique IDentifier (UUID) as defined in RFC 4122 to guarantee uniqueness between feeds and over time. | Required | This is a GeoJSON property. |
type |
String; "Feature" |
The GeoJSON object type. This MUST be the string Feature . |
Required | This is a GeoJSON property. |
properties |
One of: WorkZoneRoadEvent, DetourRoadEvent | The specific details of the road event. | Required | This is a GeoJSON property. |
geometry |
GeoJSON Geometry object with type of LineString or MultiPoint |
The geometry of the road event. The Geometry object's type property MUST be LineString or MultiPoint. LineString allows specifying the entire road event path and should be preferred. MultiPoint should be used when only the start and end coordinates are known. The order of coordinates is meaningful: the first coordinate is the first (furthest upstream) point a road user encounters when traveling through the road event. If a data producer has three or more coordinates that are on the road event path, a LineString geometry should be used because it indicates that the points are ordered. |
Required | Feed producers should aim to provide a higher density of points for sections of roadways with curves so that data consumers can more easily match road events to their road network. This is a GeoJSON property. |
bbox |
GeoJSON Bounding Box | Information on the coordinate range for this RoadEventFeature. Must be an array of length 2n where n is the number of dimensions represented in the geometry property, 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 the geometry . |
Optional | This is a GeoJSON property. |
