Transit
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.
If you run a businesses are interested in finding out more about purchasing one of these screens for your location, let us know at screens@mobilitylab.org.

What are the longterm goals for these sort of displays and how much public investment will be required?

I agree with the above commenters that it'd be awesome if this could be something that anyone could put on a screen or their phone or whatever, just by entering your location. But if Mobility Lab actually has to have its own server request the information for the two specific screens, its scalability is extremely limited.
Couldn't the computers with the screens just request the data themselves?

John Dewar: Yes, this code is open source. The latest code is not up on github right now but Eric is working on doing that. I will post an update as soon as we have it.
James, Charlie: There are a few screens including at the CommuterStore and the Arlington county building. Gabe Klein put one in the Reeves Center when he was running DDOT as well. Most of those are in the several thousand dollar range, which makes it impractical for most businesses to afford putting them in, which is why we did this project to build a much lower cost version.
Ser Amantio di Nicolao: We'd love to see these in bus stops, and WMATA has some funding to do some real-time info in some bus shelters. However, installing anything in bus shelters requires much more robust hardware to prevent being vandalized or damaged by heat and cold, running power to the bus stop, and using a mobile phone network or something for network access, which makes things more expensive. Other companies offer products for that kind of market; we are trying to develop something for a lower cost segment of the market.
Elizabeth again: Having info about Metro waits could be helpful, indeed. It's going to be a tradeoff between making the screen really easy to read and having the info be large, so people can see it from far away, versus having more info.

What would be really cool is an app that let's me plug in a destination and then based on where I am at the moment, it would tell me the various transit options with connections of how to get there. For example, if I was on U ST and wanted to get to Falls Church, the app would tell me when there's a bus/circulator to the orange line, how long till the next train, when I can expect to arrive in Falls Church, and total trip time. The app would provide me say the next 3-5 potential trips so I could say, wait 20 mins to catch the bus/train combo with the shortest total trip time.
Basically, most of this is already provided by google maps already except for the forward looking options which is really the key to minimizing trip time when you're in a position to wait around for the ideal trip.

In terms of bikeshare, what would be interesting is finding a way to locate the nearest station, and the top 5 stations used by that station (if that makes any sense). I dont' think the data feed has that information.

For those locations with only one nearby stop or only a few bus routes, it might be better to allow framing - show weather, menu, map, or twitter feed in the top frame, transit info in the bottom frame.
Also it would be nice to see bus stop numbers, for the off-chance someone needs those things.

For agencies without open data, a halfways step would be to count down the next scheduled departure. It's not the best, but as long as it's clear this is scheduled rather than real-time it could work out.

@Davin, It would be nice if Metro had something like that at their station platforms.
I'm not sure how much different they are but Gplace "had" screens which showed the real time train arrivals but I don't recall seeing them in operation for quite some time. I thought it was a good thing but something happened.

But way to go, this seems like a organizational upgrade from the CTA interface, & hopefully we can learn from it when we institute bike share this spring.

Please remember that not everyone has 20/20 vision. That screen looks far away, and the font tiny.
And remember that someone with bad vision is more than likely relying on transit because they cant drive.
Please install these things at eye level, where someone can walk right up to it and get as close as they need. The current installation (from the picture provided) appears useless to many, many people.

Someone pointed out that a limiting factor is the need to go through a centralized web server to obtain the real-time predictions. This is difficult to get around because different transit providers have very different API's for their real-time feeds, but it shouldn't be impossible.

Then can we get it to do connections? e.g. WMATA to MARC, MetroBus to MetroRail, etc.

As the README says, "The Transit Screen code is in its early stages, so future code changes to improve reliability and coding elegance are on the way. In the meantime, here are some instructions to help you get started."

In general, it would be ideal if the listings mimicked the font and color of the relevant transit system. While this is mostly true, its unclear why WMATA buses are listed with a blue background. In contrast, the use of an orange background for the orange line trains is great -- intuitive and user friendly.
Bus
The white route name next to the bus icon is small and hard to read.
The meaning of the small numbers to the far right of each bus listing is unclear to me. Perhaps they could be better defined or they could be removed.
CaBi
The words Capital Bikeshare are hard to read because of the red script. It may be worthwhile to do something to improve the readability, without altering the color or font. Perhaps it would be as simple as increasing font size.
The term docks can be confusing since the number of docks does not change based on whether or not they are filled. Therefore, it could be changed to say empty docks or available docks.
The use of a pie chart is great -- particularly the fact that the red and gray each refer to the relevant column (that is, bikes or docks).
Again, this is intended as constructive criticism, not a nasty anonymous comment, because these screens are really great.

Could you add GPS functionality to a static location and/or smartphone app to tell the viewer how far of a walk it would be to a certain stop/station? Okay the x bus is coming in y minutes, but how long would it take to walk (or run) there?
