wrongWayOK

Specifies whether the router can create wrong-way routes on a layer. By default, wrong-way routing is permitted. When wrongWayOk is set to false, the router will not create wrong-way routes on the layer.

Setting wrongWayOk to false does not prevent fix_errors from adding a wrong-way segment to fix an error.
