#1080: Feetback

Pedestrian crossings often get put where people don’t actually want to cross the road. Today’s invention simply detects where people cross most frequently and puts the crossing there.

This consists of a small, motorised cart which moves very slowly, and changes direction randomly, along the edge of a street -staying in contact with the kerb.

It projects a set of bright, laser light zebra stripes across the road so that the current position of the crossing is very visible to both vehicle drivers and pedestrians.
The cart keeps track of its historical positions along the kerb and the the number of times that its projected bars are reflected back by crossing pedestrians at each location (it would ignore things passing over the crossing in the road direction, like wheels). The cart would also remain unaware of people crossing in other places (ie whenever it happened to be inconveniently placed).

The device moves less as its foot traffic rises and eventually positions itself so as to be where people choose to cross most frequently (until eg some change in the street forces people to cross elsewhere, at which time the process of adaptation restarts).
