David Yanofsky of Quartz put together this starkly informative infographic showing the spatial configurations of a few of the world’s biggest bike share programs based on station locations. Elaborating on the imagery, Yanofsky writes, “New York’s new system is compact and dense. Washington DC’s is expansive and sparse. Seoul’s is bifurcated. Paris’s is comprehensive.”

Station density directly reflects a system’s ability to meet the trip demands of a community. In general (though not always), the darker the set of dots, the better system the community has and, thus, the more use the system gets.

The data for the graphic was obtained from Oliver O’Brien’s website, which uses open-source data to keep tabs on the distribution of bike share bikes based on station location. Because O’Brien’s site relies on publicly available data, he has been unable to display data from many of the world’s largest programs found in China. Nonetheless, this graphic provides a great way to understand and compare city layouts, station density, and distribution.
