I was able to successfully parse through BART's GTFS realtime Service Alerts and TripsUpdate feed. I also looked at the official protocol buffer for Java tutorial page and was able to compile and run the tutorial. https://developers.google.com/protocol-buffers/docs/javatutorial

The next part for me is figuring out how to create a Realtime feed maybe preferably Service Alerts first for my GTFS static data. From what I understand a GTFS realtime feed is like sending protocol buffer data that is serialized to a webpage and then writing a script that takes in the web link that refers to the page and deserialized the data using HTTP GET. I was thinking of using Visual Studio and ASP.NET core to do this. Is there an example project I can refer too and/or am I even on the right track in the first place?

Take a look at the awesome-transit list of gtfs-realtime stuff. A lot of libraries within the OneBusAway project are probably your best bet for seeing code in action that deals with gtfs-realtime. For example, maybe you can look at onebusaway-gtfs-realtime-exporter.

  • Thanks for pointing out the Onebusaway project. I learned something from the Alerts demo page that I should create a new and seperate component that creates a realtime data alert stream in JSON. https://github.com/OneBusAway/onebusaway-gtfs-realtime-alerts-producer-demo/wiki – axesspwns Dec 31 '17 at 22:16
