Bicycle Count Map
What does a city look like if we visualize only the cyclists? This map shows daily bicycle counts at several hundred locations throughout the City of Portland.

Each count is marked by a circle; its area represents the number of daily cyclists. The circles are connected using a modified Delaunay triangulation in order to suggest cyclist movement throughout Portland. The triangulation was adjusted to remove connections between points that are not physically connected, such as those crossing the Willamette River at locations that do not offer a bridge.

The map invites speculation and interpretation. It describes several of the most-traveled routes such as the Springwater Trail corridor and the North Williams route. Areas that are seldom used or under-served by bicycle infrastructure, such as outer-east Portland, are also revealed.
