Here’s some data that might prove useful: http://www.swivel.com/data_set.....et/1010688

It’s the number of riders from each station. Doesn’t specify whether they’re coming/going (or at least I didn’t see it mentioned).

Go Red Line to Shady Grove! It would be great to see directionality inbound/outbound as well…

In Philadelphia (like NYC) we only have entry data. Also muddling is the fact that there are some free transfers between lines in certain places.

well we don’t have trains where I live, but I did a viz on some real data supplied by the authority that runs the bus network.

The MTA does release ridership numbers. I believe they are counts of entries at a station. Search the forums of straphangers.org and I’m sure you can find them – they’re big Excel spreadsheets.

How I wish we had better access to public transportation data.
In Paris, the new passes are RFID-enabled, so they can track you wherever you go, including your trajectories within the station (which are almost never the shortest route from entrance to platform).
but for a general view, having the official, Ã¼berdetailed data won’t help much.

Interesting. The DC Metro actually does (or should) have all the data, because their system is variable-fare, which means you have to swipe a farecard when you get on *and* when you get off. NYC, to take a contrasting example, can’t connect exits from their system with entrances. (On the other hand, they could at least get all the data from the counters in the turnstiles, and that could give them a pretty good picture of the people flow.)
