Allow Polygon Geometry Type

[DeraldDudley]

Summary

The Extension Subgroup has identified use cases where data consumers can use polygons to mark roads within an area as closed or restricted due to events or incidents.

Motivation

Remove the administrative burden of marking individual roads within an area as closed or restricted by bounding them with a polygon. E.g. All roads within this polygon are closed.

@DeraldDudley does this apply to the events defined in TDx only or are you proposing it for work zones as well?

The City of Portland uses polygons to represent restrictions to the public right-of-way. The polygon allows us to represent an impact to the parking and sidewalk as well as travel lanes. Having this option available would be helpful in avoiding duplicate data entry.
