We are wanting to pull or Estimated Time of Arrival into some Digital Signage - we can't find how to access our API much less (if I'm honest) what to do with that once we get it. Can anyone give me some help?

Hi Graham,
Currently, the Jacksonville State University OpenAPI is not yet enabled for public usage. We have not received request from the university to enable the OpenAPI. Please submit your request through this portal https://transloc.zendesk.com/, or contact our customer care to enable the OpenAPI for Jacksonville State University.
For information on accessing the OpenAPI, please refer to http://api.transloc.com/. If you have any questions about the OpenAPI, feel free to ask here.
Thanks,
Stu

Stu,
Thanks for that info - that would be a good place to start. I've contacted our Bus Manager and she is going to get that submitted.
Can you give me a bit of direction on what to do once that is enabled? I've never used an API before so I'm not sure where to begin.

Graham,
Since you care about estimated arrival times, you need to query the API about the arrival times and then process them. Please find the way to access arrival estimates API here: http://api.transloc.com/doc/#arrival-estimates. Also, you might need to get the internal ID for stops and routes. Please refer to http://api.transloc.com/doc/#routes and http://api.transloc.com/doc/#routes. Note that the IDs do change over time, whenever there schedule change or route/stop change. So you should to refresh the route/stop information every once an hour or so. The agency ID for Jacksonville State University will be 56.

Stu,
I've look at that page, I still don't know what to do with that information. I don't know what HTML or anything to put on the page to use it. Forgive me API ignorance, I have an art degree :)

Sure.
First, if you guys have computer monitors/TVs for the digital signage, you don't have to use OpenAPI. Open this link http://jsu.transloc.com/livedisplay/ in a browser and configure it as you would like. Then copy the URL in the browser URL bar and paste it to the browser that shows up on the signage.
Otherwise, what you need to do is to write a computer program that fetches and parses from the API. With different programming languages it will be slightly different. But in general you would want to make an HTTP request to the URLs that the documentation shows you and grab some JSON documents from there, then parse the document and extract useful information. After you have the information, you can write them to the signage. The program should repeat this process for up-to-date information.
Does this help you?

Stu,
I've been following this thread with interested - I hadn't seen the livedisplay webapp before. Very cool! I do have a question about it though. Is there a way to limit the view to a single agency? I was playing with triangle.transloc.com/livedisplay and could not find an easy way to have just one agency (just Chapel Hill Transit, or just Triangle Transit, for example) to display. While we're lucky in our area to have so many overlapping agencies, it does make for a cluttered display when folks are generally only interested in using the local service, and may be confused by the regional service or the local service from another agency showing up on the edge of the map.
Thanks,

Hi Jason,
Thanks for your email.
No, currently the live display don't have a way to limit what agencies to look at. You suggestion is actually a very good one. We will consider adding this functionality to our live display.
Thanks,
