Wayfinder

A wayfinder is a construction with an extra segment with direction information, for situations in which it may be unclear how to continue on the same road the user is driving on.
Wayfinders are now only useful at on- and off-ramps and at the transitions from one motorway to another. At all other locations, a navigation indication is better used.
