TransitScreens are an experimental project from the Mobility Lab: Digital screens showing real-time transit arrivals and Capital Bikeshare availability.

Every 20 seconds, our web server queries each transit agency for the arrival predictions for selected stops, then relays the data to the screens.

The actual unit inside the shops is just a low-cost, barebones Linux system connected to a standard computer monitor and the business’s own Wi-Fi and power. We’ve configured the box to automatically load up the screen when it starts, so there’s no need to log in or launch an app after the unit is plugged in.

This project is only possible thanks to open data and APIs from our transit agencies.
