I'm working on my last semester project which is based on real-time transit. So, I want to develop website (using Python + Django Fw) that will show all our university buses' real-time Geo-location (Google map API or any other please suggest the best one) to the university students and professors, and also shows the bus arrival times for bus stop nearest to them (From wherever they are). This is main module of my project. So the question is that
"If you provide a transportation service that is open to the public, and operates with fixed schedules and routes, we welcome your participation"
in Google's documentation on
"Why Google Maps?"
So in this case my website can only be accessible by our university persons, and I think it may violet Google's policy. And second question,
About Q1:（May I use Google transit for that? ...） You might be able to use Google transit by using Google Maps Directions API(https://developers.google.com/maps/documentation/directions/). But, there are several limitations. Transportation agency must be in a supported city(http://www.google.com/landing/transit/cities/index.html) and a public transportation agencies(https://developers.google.com/transit/gtfs-realtime/).
About Q2:（If I implement this is it accessible ...） Other peoples may access your transit feed info. But, there are Quality Assurance Review(https://support.google.com/transitpartners/answer/1106422?hl=en&ref_topic=1095593) about the info before launch it.
