This is a collection of assignments about public transportation in Atlanta. The assignments are designed to 1) develop mapping and data analysis skills, 2) form an understanding of how MARTA is used today and how the system evolved to be in its current state, and 3) foster thinking about sustainable transportation. The problems are based on the IoT (Internet of Things) datasets of MARTA, which includes passenger counts of vehicles and Breeze card swipes at terminals. Reflection questions about the history of transportation are based on the 2017 report Opportunity Deferred: Race, Transportation, and the Future of Metropolitan Atlanta.
