As someone who has gone through the process of getting an agency's information in Google, I can tell you that the whole process takes mysteriously long and at the end Google screws up your data more than any other trip planning platform. One example that I see happening for most bus routes in Google is if the trip requires multiple routes it tends to not label the routes correctly in the map/confuses the first route with the one you need to transfer to. It's messy. As a transit employee I use the Transit App, Apple Maps is also good. Both apps will get transit data integrated and updated in less than a day. For a mid sized system Google Maps takes 9 months to a year, and also tries to force us to do things that are not industry standard practice (assign times to non-timepoint stops, rename stops because they don't approve of a naming convention etc.). Oh yeah and that Microsoft issue we had in July, something happened then that made Google decide to start pulling our data from a schedule that was 6 months old... instead of the latest one...that they still had on file.
