I Tracked an NYC Subway Rider's Movements with an MTA ‘Feature’

In the mid-afternoon one Saturday earlier this month, the target got on the New York subway. I knew what station they entered the subway at and at what specific time. They then entered another station a few hours later. If I had kept monitoring this person, I would have figured out the subway station they often start a journey at, which is near where they live. I would also know what specific time this person may go to the subway each day.

During all this monitoring, I wasn’t anywhere near the rider. I didn’t even need to see them with my own eyes. Instead, I was sitting inside an apartment, following their movements through a feature on a Metropolitan Transportation Authority (MTA) website, which runs the New York City subway system.
