Curb extensions, also known as bulb-outs or neckdowns, are a traffic calming measure and street design element used to extend the sidewalk, reducing the crossing distance for pedestrians and increasing their visibility at intersections or midblock crossings. By physically and visually narrowing the roadway, curb extensions create a pinch point for traffic, slowing vehicles down and increasing driver awareness. They are typically implemented at intersections, aligning with the parking lane, and can be accompanied by features such as bollards, planters, or seating areas to enhance pedestrian safety and comfort. Curb extensions also provide additional space for streetscape amenities, such as benches, bike racks, or landscaping, contributing to a more vibrant and pedestrian-friendly urban environment. Moreover, they can improve drainage by directing stormwater runoff into green infrastructure elements like rain gardens or bioswales, which filter pollutants and reduce the burden on sewer systems. The design of curb extensions varies depending on the specific context and goals, but they generally aim to prioritize pedestrian safety, calm traffic, and create a more engaging public realm.
