Exit Print Page and Return to Intersection Median Barriers

Intersection Median Barriers:

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.

Intersection median barriers need to keep walking and bicycling flowing freely through the neighborhood.

• Reduce cut-through traffic on a neighborhood street.

• Local residents need to be provided access so they do not have to drive excessive distances to their homes.
• An analysis of traffic patterns should be done to ensure that cut-through traffic would not be diverted to a nearby street.
• Design should ensure safe and convenient bicycle and pedestrian access.
• Ensure that emergency access is not negatively impacted. Some designs (e.g., high mountable curbs) may allow fire truck access, while inhibiting cars.
