Another thought on street clutter...although widely recognised as a significant problem for pedestrians (both because it reduces the available space for walking and because it can represent a serious hazard for some people, most obviously those with visual impairments) what is less widely acknowledged is the apparent effect that street clutter has on attracting other clutter.
From my observations, there seems to be a clear pattern where temporary obstacles of one kind or another are often placed next to other obstacles. For example, an ‘A-board’ may be placed next to (or chained to) a signage pole. Old roadworks debris (cones, signs, sandbags etc) are left beside or behind a utility box or cycle stand. Wheelie bins may be placed next to a phone box and so on. Fly tipping of old mattresses or pallets etc is most likely to be next to some pre-existing clutter. Cycle stands on the pavement will invite the addition of A-boards or bins. The more untidy the space is, the more likely something will be added to it. So clutter attracts clutter - I’ve come to think of this as “the Iron Law of Street Clutter”.
This is important because not only does one form of clutter seem to encourage the accumulation of more clutter, but it is often the combination of different forms of clutter - say ‘A-boards’ and signage poles - which most restrict pavement space and which most cause danger. No clutter is much better than some clutter.
