Amsterdam cycling advocate Marjolein de Lange regales us with this tale from 2006 about how cyclists came up with a very simple solution (draw bike box outlines directly on the pavement!) to better organize the chaotic, random bike parking outside of a popular supermarket which is used by many blind patrons, physically challenged individuals and seniors. It's so simple and shows how sometimes engineers might over think a simple solution to a problem.
Marjolein tells us these are now common in many shopping areas in Amsterdam and other cities. Although I will add one comment: this also only works well in cities where nearly all the bikes do have kickstands.
