Circular graphs show relationships between time use and transportation
Andrew Myers uses circular graphs or “Circos graphs” as a visual tool to highlight relationships derived from large amounts of data from the American Time Use Survey. Circos graphs were initially used in the natural sciences to represent genome sequences, however, their utility for visualizing large data is particularly helpful for representing relationships between time use and transportation use among Americans with mobility impairments.
Andrew, a graduate student in Geography, assists Dr. Craig Ravesloot with this research project. The purpose of this study was to examine the effects of having a mobility impairment on the way people use time and transportation. They found that people with mobility impairments spent less time working and more time watching TV. Furthermore, about half of everyone with severe mobility impairments didn’t go anywhere during the day, an issue that makes it difficult for people with mobility impairments to become involved in their communities.
According to Andrew, “People with impairments, like most people, tend to rely on using their own personal vehicle for transportation. When they were able to have their own independent transportation, they spent more time in productive activities such as work and less time in non-productive activities such as watching TV.”
