Biking has many benefits. When people choose to bike over drive, impacts are made in the fields of health, environment, travel, and safety. However, there are obstacles that biking presents compared to other forms of transportation. Bikes are expensive, can be easily stolen, and are bulky to transport. Additionally, women and people of color are more discouraged to routinely bike as a method of transportation as fears of racial profiling and gender-based violence are frequently generated while navigating public spaces.
Chicago’s bike-sharing service, Divvy, helps provides a solution by providing and maintaining over 6,000 bikes across Chicagoland. Divvy Bikes are an easy, accessible, and affordable way to get around the City of Chicago. With growing evidence from previous research, Divvy expanded their services over the summer of 2020 by placing stations in poorer, disadvantaged areas on the Southside of Chicago. Additionally, Divvy introduced ebikes for use during the last week of July which can be parked at a public bike rack and do not need to be docked.
This analysis seeks to provide insight into various aspects of historical Divvy rides. Focusing on 2020, data analyses from the months of March through October is displayed. Noticeable trends are observed in response to a couple of city-wide shutdowns (related to both COVID-19 restrictions and social unrest protesting racial injustices). By examining kernel densities and other key insights, popular travel times and directions as well as demographic data is further explained.
