Research and open data on how the city moves.

• ResearchEvaluations of policies already in place, such as congestion pricing, bus cameras and the fare-free bus pilot, and proposals for what to try next.
• ToolsTrackers rebuilt each night from MTA data, such as subway slow zones and bus speeds, and tools to test changes of your own, like closing a bus stop or drawing a bus lane.
• DataThe tables behind every page, cleaned and free to download under CC BY 4.0, with docs for each table and a SQL console that runs in your browser.

We work from public data: MTA subway and bus feeds, which we archive ourselves around the clock; MTA open data; NYC DOT; and NYC Taxi and Limousine Commission trip records.

Each page says where its numbers come from, how we made them and what they can’t tell you. The docs cover every table, and the tables are free to download, so anyone can check our work and redo it.

If you find a mistake, email hello@transitlab.nyc with the page and what looks wrong. We check it, fix it, and add a note to the page that says what changed and when.

Transit Lab is not part of the MTA, the city or any other government body, and doesn’t speak for them. The site has no ads and nothing for sale, and the data is free with nothing to sign up for.
