Sidewalks and designated paths leading to schools promote the use of nonmotorized modes of travel. For better pedestrian comfort, especially adjacent to high-speed traffic, it is desirable to provide a buffer space between the traveled way and the sidewalk. For rural sections without curb and gutter, sidewalks should be placed between the ditch and right-of-way line if practical. Sidewalks should be wide enough to accommodate the volume and type of pedestrian traffic expected in the area. They should be wider than minimum in the immediate vicinity of schools, where there are heavier pedestrian volumes.
Sidewalks will more likely be used if they are well-maintained and free of debris, encroaching shrubbery, and tree limbs. Bumps and uneven surfaces created by settling or underlying tree roots can cause tripping and discourage sidewalk use by students traveling by foot and in wheelchairs. Public works agencies must not pile snow on sidewalks when clearing snow from streets and should clear curb ramp accessways to sidewalks.
