Description

Many types of ways should not share edges, particularly highways, railways, and waterways. Generally these should not share edges with buildings either. We should flag these instances.

Note that many ways can share edges, such as adjacent buildings or a curb line along a pedestrian area.

Contributor guide

Research direction
Examine the existing validation system in iD to understand how warnings are generated, then add a new check for collinear ways that should not share edges (e.g., highways, railways, waterways, buildings).
