I am trying to make sense of wheelchair width requirements.
I understood required width of floor space for wheelchair is 30". Whereabout solid vertical obstruction is in the way and handrail is normally absent, this increases to 34" to include handgrips on the wheels like drinking fountain alcove, restroom door, or front approach niche, etc, and 32" for short passage of less than 24" in pathway bottle neck.
I just don't understand why require 33" (or 36") width in assembly area, and 36" in hotel/motel room or 36" for retail aisles and elevator door ? Sure I can memorize these differences, yet it seems a little hair-splitting matter considering the code would better served being consistent.
