The Data and Statistics division of Seoul’s metropolitan government analyzed late night call records provided by the Korean telecom KT Company to plan bus routes in a more inclusive manner. This research redirected Seoul's Owl Bus service, buses that operate late at night, to focus more on women's security and low-income groups. As explained by the Data Impacts website, "Since 2012, Seoul’s "Owl Bus" service has saved the city’s lower-income groups approximately $1.2 million by providing more affordable transportation using cell phone data to plan late night bus routes."
