Yellow feet stickers
Living Streets Aotearoa Inc, together with the Wellington City Council in New Zealand, designed some bright yellow, self-adhesive feet bearing messages about the need to keep footpaths clear for pedestrians.
Then the group started work – wandering around the local streets sticking the feet on cars parked across footpaths.
The Reclaim the footpaths - please don't park on the footpath campaign graphically demonstrated the route walkers would take if the car was not parked on the footpath. The clever campaing attracts media attention and gets a much better reception from drivers than harshly-worded notes or punitive measures such as parking fines.
