This fall, I took a Network Models class (1.022) at MIT. The class covered a lot of cool concepts of networks/graphs, such as node centralities and shortest paths, as well as important applications, like the behaviors of epidemics and social networks. Another application of this theory — the one I chose to do my final project on — is transportation networks. For my final project in this class, I modeled the T and experimented with making some changes to the network.
If you are unfamiliar with the T…
The T is Boston’s subway system. The Massachusetts Bay Transportation Authority (MBTA) operates the T, as well as the buses and commuter rail. There are five lines on the T: the Red, Blue, Green, Orange, and Silver Lines. The Silver Line is actually a bus, and I did not include it in my model.
