Dublin City Council has produced a local version of the iconic image showing how much space different modes of transport takes up:
As with the most international examples (see below), the Dublin version is supposed to be an illustration to get people thinking.
It’s not supposed to be exactly measured of how much space the modes of transport take up when moving. But rather it shows that while some car drivers, business people and councillors think that cars fulling up a street means a busy street, the fact is cars with a small average occupancy rate clog up streets.
The same amount of people walking, cycling or on a bus or tram won’t fill up the same space, so, compared to where cars are, streets can look a bit more empty when cars are taken away or the space from them is reduced.
There have been various versions of this image and similar graphics produced, including some animated examples, starting with the first image from the Netherlands from Fietsersbond, the Dutch cycling campaign group.
As a side note, you might also enjoy a collection of images on The Guardian showing 50 years of Dutch anti-car posters, which includes a nice graphic of three parking spaces for cars vs 12 bicycle parking spaces and more space for city life.
And a version with updated graphics:
