Shows OpenStreetMap restrictions and analyses them to find incorrect or unnecessary restrictions. The Overpass API is used to retrieve the data.

Green ways represent "only_"-restrictions, while red ways respresent "no_"-restrictions. White ways are connected to the via-node of some restriction, but not part of any restriction.

Complete arrows represent one-way streets. Arrows on only one side of the green/red lines represent two-way streets, where the restriction only affects the shown direction.

This tool has some limitations:
- Restrictions where the "via"-member is a way are ignored
- Restrictions for specific vehicle types, eg. "restriction:hgv" are ignored
- Restrictions that contain non-car streets (e.g. cyclways) are ignored
