Exploring Nice Ride job accessibility and station choice
Although bike share systems are becoming more popular across the United States, little is known about how people make decisions when integrating these systems into their daily travel. For example, when more than one bike share station is located nearby, how do users choose where to begin their trip, and what factors affect their decision?
In a study funded by CTS, researchers from the U of M’s civil engineering department sought to answer this question by investigating how people use the Nice Ride bike share system in Minneapolis and St. Paul. Professor David Levinson and graduate student Jessica Schoner examined how Nice Ride affects accessibility to jobs and developed a model to predict station choice.
In the first part of the study, the researchers created maps showing accessibility to jobs by census block for both Nice Ride and walking—as well as the difference between the two—at time thresholds ranging from 5 to 55 minutes. At lower thresholds, fewer census blocks have job accessibility via Nice Ride because of the time it takes for a person to walk to the Nice Ride station. However, at higher time thresholds, Nice Ride provides an improvement over walking. Overall, in blocks with both Nice Ride and walking job accessibility, Nice Ride provides access to 0.5 to 3.21 times as many jobs as walking.
“This type of information can be used by bike share system planners to identify where new stations could be built to maximize their impact on job accessibility,” Schoner says. “They could also look at accessibility to other destinations, like parks, grocery stores, or tourist attractions, depending on the goals of their system.”
Levinson and Schoner also developed a theoretical model for bike share station choice. The model considers users’ choice of a station based on their preference for the amount of time spent walking, deviation from the shortest path (the closest station may not be in the direct path of the person’s destination), and station amenities and neighborhood characteristics.
Understanding people’s station preference can help provide guidance to planners for bike share system expansion, densification, and optimization, Schoner says.
“For instance, even though spacing stations along a route would allow people to walk in the direction of their destination to pick up a bike, people’s strong preference to spend more time biking indicates that clustering stations near where they are starting and ending their trips might make more sense,” Schoner says.
