Evaluating Efforts to Improve the Equity of Bike Share Systems

Nathan McNeil John MacArthur , Jennifer Dill , Joe Broach
BREAKING BARRIERS TO BIKE SHARE: Insights on Equity. Public bike share systems have rapidly expanded across the United States in recent years. However, there is evidence that significant portions of the population are underrepresented among bike share users, including people of color, along with lower-income, female, older adults and less-educated groups.

The project demonstrates how an inexpensive system can add new functionality to existing signal controllers, giving bicyclists an efficient way to cross a controlled intersection. The system proposed and demonstrated integrates three components: (1) a Bike Connect box that resides near the signal-controller and is connected to it, (2) an application that runs on a Bike Connect device… Read More
