Collapses small, open configurations of road segments that interrupt the general trend of a road network, such as traffic circles, for example, and replaces them with a simplified depiction.

Configurations are collapsed regardless of road class if the diameter across the open area is less than or equal to the Collapse Distance parameter. All uncollapsed roads from the input collection are copied to the output feature class.
