Tools to Address Speeding, Volumes and Pedestrian Safety
Bulbouts are extensions to the curb located at intersections, which result in a narrower curb-to-curb roadway width. Costs range from $2,000 for simple designs to $50,000 for highly aesthetic versions. These are often used with plantings and street furniture to enhance the area and make the restricted width more conspicuous.
Their primary purpose is to "pedestrianize" intersections by shortening crossing distances. Vehicle turn speeds can be reduced providing increased pedestrian safety.
Bulbouts are sometimes called nubs, neck-downs, knuckles, intersection narrowing, corner bulges or safe crosses
