Ever wonder where everyone at your Metro station is going? This visualization from PlanItMetro shows both how many people enter at any given station on an average weekday along with where, exactly, all of them exit.
I noticed that a lot of Arlington riders use Orange lines to commute to stops on the Silver Line. Specifically, about 8% of the riders who get on at Ballston head out to a new Silver Line station.
What do you see when you use the tool?
