Sidewalks should be continuous and provide a clear path consistent with pedestrian volumes, but always wide enough to allow two people using wheelchairs to pass one another. Allocate space for building entrances and commercial activity outside the clear path. Street furniture, trees, and utilities should serve as a buffer between the clear path and moving traffic.
Safe and frequent pedestrian crossings support a walkable urban environment. Pedestrian crossings should be located at all intersections in addition to mid-block points where pedestrian traffic is anticipated or desire lines are observed. Support marked crossings with signals and stop controls, raised elements, refuge islands, and narrow corner radii. Slow vehicular traffic approaching pedestrian crossings.
Pedestrian refuges reduce crossing distance and provide waiting areas for people who cannot cross the full width of the street in the pedestrian interval. Use pedestrian refuge islands whenever speeds and vehicle volumes make single-stage crossings dangerous for some users, and in most streets of three or more lanes of traffic.
Sidewalk extensions are an extension of the sidewalk, usually at the point of the intersection, visually and physically narrowing the roadway and shortening crossing distances. They make pedestrians waiting to cross the street more visible to drivers, calm traffic speeds, and increase the available curb space for people waiting to cross. Large sidewalk extensions can accommodate street furniture, benches, vendors, transit stops, snow storage, planters, and trees.
