The Veterans Administration does research on sidewalks.
A pavement test area sits behind the Veterans Administration laboratory in Pittsburgh, PA. Wheelchair users rode over test sidewalks with different brick patterns to measure vibration and comfort.

Once that relationship is understood, standards can be developed for allowable roughness in sidewalks and walkways.
