In its analysis of bike-share systems across the U.S., NACTO found that stations that are close to other stations see more use. In addition, bike-share systems with higher overall density — New York and Paris are leaders — tend to have higher ridership than more dispersed systems like Minneapolis’s Nice Ride.
Riders from systems around the U.S. report the primary reason they use bike-share is because it is easier or more convenient than available alternatives. But users don’t want to have to travel a long distance searching for a place to pick up or return a bike. So the accessibility of bike stations — and, crucially, accessibility by walking — is a primary determinant of their usefulness.
“Research on transit users finds that most people will walk no more than a 1/2 mile to get to commuter rail, with a large drop-off beyond a 1/4 mile,” the report says. “The distance someone will walk to use a bike appears to be much smaller — about 1,000 feet or 5 minutes walking.”
Furthermore, placing stations close together across a contiguous area offers “exponentially” more destinations than those that are isolated.
