This shortened version of a raised curb median extends through the intersection
to prevent cross-street through movements and left turning movements
to cross-streets from the main street.
This treatment can benefit pedestrians who need to cross any leg of the
intersection, but restricts vehicle entry into and out of neighborhoods
and can therefore greatly reduce cut-through traffic. However, since
this treatment can dramatically influence traffic patterns and have potentially
negative consequences caused by shifting traffic, it should be used cautiously.
Crossing islands can provide benefits to pedestrians if that is the desire.
This is also a traffic management technique.
Cut-throughs must be incorporated into the design for pedestrian and bicyclist use.
