Experimental real-time transit screens come to Arlington, DC
Every 20 seconds, our web server queries each transit agency for the arrival predictions for the stops near both test sites, 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.
We are continuing to build the system so it can be deployed quickly and cheaply throughout the region at participating shops, bars, cafes, and restaurants. Ultimately, a business will be able to sign up, type in their address, and get a screen automatically customized with the nearest bus stops, Metro station, and Capital Bikeshare station. And someone with their own computer connected to a standard computer monitor will be able to set up their own screen for free.
This project is only possible thanks to open data
