What is the MBTA intent for their open source on GitHub?

• are you encouraging contributions of features or fixes from the public?
• is github.com/mbta the live repository for MBTA software engineers?
• have any local universities had their software classes fork your code and work on improvements?

p.s.

I was poking around looking at the visualizations that are used for the displays around the system. I was admiring them in the stations the other day for their clarity, readability, and understandability. It is really both an art and a science to find ways to display relevant information in a way that is so understandable. Congratulations to the team because I think they did a wonderful job.
