Figure 5-2 Curb Extension Example, USDOT/FHWA
The typical curb extension is the
width of a parked car (6') but can be reduced to accommodate turning vehicles if necessary. Extensions are not appropriate at intersections where traffic operates in the curb-lane. The length should be as wide as the crosswalk, at a minimum. An extension can be located on one or multiple approaches depending on the intersection configuration. Street furniture and plantings placed on an extension should not interfere with pedestrian flow or visibility between people walking and driving. PEDESTRIAN REFUGE ISLANDS A pedestrian refuge island creates a protected space for people while crossing multi-lane, bi-directional traffic. Refuges are particularly valuable at unsignalized crossings to reduce the unprotected time that people spend in the intersection and allows for two-stage crossing of larger streets. Refuges resemble median cut-throughs, where pedestrians are provided a space to continue through a median at street level while the median provides protection on both the left and right of the crosswalk. The median refuge dimensions must safely accommodate a wheelchair, stroller, or bike. Considerations Refuges should provide space for a person with a stroller, wheelchair, or bike. The cut-through space should be as wide as the marked crosswalk. Plantings in refuge medians should maintain intersection visibility. Detectable warning strips are required on both sides of the refuge, even for at-grade crossings. Pedestrian Refuge and Offset Crosswalk, FHWA Traffic Calming ePrimer
