Visualizations

A visual exploration of BART ridership throughout a typical workday. Watching the video below is fun, but the actual tool – made with HTML/CSS, JS, .d3.js, Sketch and BART ridership data – is even better. Click here to view it

After you’ve watched it through to about 2pm, some controls will appear down the bottom left to change the speed of the simulation, and also switch between “inbound” and “outbound” trains (which I think should be labeled more simply as “westbound” and “eastbound” as the path always follows a train’s trip from one end of the line to the other). Ray tells me that only showing one direction at a time was an intentional tradeoff, so as to not overwhelm the viewer on top of handling performance in the browser.

Ray’s also written a short piece on the background behind the project here, which is an interesting read.
