Experimental real-time transit screens come to Arlington, DC
If you go into the Java Shack coffee shop near Court House in Arlington, or walk past the Red Palace bar on H Street in DC, you will see a new experimental project from the Mobility Lab: Digital screens showing real-time transit arrivals and Capital Bikeshare availability.
At Java Shack, customers waiting for coffee or sitting at a table can see the next Metrobus, ART, or Orange Line arrivals, and bike availability at the Capital Bikeshare station across the street. The Red Palace screen faces outward onto the sidewalk on H Street, letting passersby see their bus and CaBi options.
Stop by one of these businesses and let us know what you think! This project is still in an early stage, so the screen displays will evolve over time. Moreover, we're hoping to add screens in more businesses soon.
One of the main challenges in convincing people to switch to transit is the unpredictability of bus arrivals. If every stop featured a digital screen displaying the number of minutes until each bus arrived, more people would be willing to take the bus.
Outdoor screens, however, are expensive to install, which is why we created this indoor alternative at a fraction of the cost. For the past few months I have been working with Andy Chosak and David Alpert at the Mobility Lab in Arlington to bring this low-cost alternative to fruition.
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 from our transit agencies. We can only pull bus and train predictions as well as the status of each CaBi station because the agencies behind these systems have wisely chosen to provide stop locations, route information, and real-time arrival predictions to outside software developers.
