For those who can’t get enough of charts showing the behaviour of TTC routes, I highly recommend a visit to Visualizing MBTA Data, a project of Mike Barry and Brian Card at Worcester Polytechnic Institute.

In their article, they show data for the movement of trains, for headways and for trip times between points, not to mention station usage counts. All of this can be explored interactively to view specific sections of the network.

(For more details about their project, please see this handout from a recent presentation.)

As they note, the idea of plotting train movements goes back to the 19th century. I certainly didn’t invent it. The biggest challenge has been to take masses of data from the TTC and convert them to a format that is digestible and illustrates various factors of transit operations.

An encouraging note: the TTC is now doing some of this type of analysis itself, and this will inform work on improved scheduling and better monitoring of service quality.
