TEECOM’s Oakland office is practically on top of the 12th Street BART station, so it just makes sense to give our staff a convenient way of checking train departure times. And while there are lots of real time BART information displays, this one is uniquely ours. Starting with an existing open-source project, we improved the functionality by making the signage readable from across the office.
Line-specific colored bars represent the amount of time left before the next train departs. Shorter bars mean hurry up! And when you’re not in a hurry, it’s kind of mesmerizing to watch them tick down as trains approach. It also shows the local weather and current time.
If you’re into the tech that powers a display like this, the content is a dynamic web page in a full screen Chromium window. The browser runs on a tiny Raspberry Pi connected to our network via Wi-Fi. Data sources include the BART API, Forecast.io for weather, and a few of these great historical BART pictures from Eric Fischer.
We already have list of future enhancements, but first and foremost, we’ll be adding a second screen to show even more useful data.
