An Analysis of Interactions on the Boston Subway

less than 1 minute read

Published:

I made my first ever visit to Boston this past week, and while I was there, I was able to put together a small research project. On a subway ride, I carefully noted each of the interactions between the 50 riders in the train car I was in, during a 15 minute ride. Edge weight represents number of minutes spent talking to each other.

Nodes are colored based on degree centrality, sized based on eigenvector centrality, and spaced with Fruchterman-Reingold in Gephi.


So far, the research is merely descriptive, but I think some real insights could be made through running an actor-oriented model.
