TransitScreen is an experimental project from the Mobility Lab: Digital screens showing real-time transit arrivals and Capital Bikeshare availability. In real time, the web server queries each transit agency for the arrival predictions for selected stops, then relays the data to the screens.

This project is only possible thanks to open APIs from our greater Washington transit agencies.

• Here is a constantly updated table of agencies and their open data and APIs.

Instructions for setting up a local TransitScreen hacking environment:

• Mac
• Linux
• Windows

Some very sketchy notes on the code:

• Backend
• Frontend

Instructions for setting up a TransitScreen kiosk:

• Android Tablet
• iPad Tablet
• Pluggable Linux computer such as these computers
• Raspberry Pi

There are some other transit screen projects.

If installed in the windows of commercial establishments, these real-time information displays may be subject to Sign Regulations.
