I did an internship in a bus company several years ago and we finally abandoned the idea of GTFS because they (Google) were so uptight about the correctness of the data. We had a few trips that were non consistent (the average speed was something like 150 km/h - 93 mp/h) that we couldn't do anything about and they refused to integrate those data. Several bus stops were also too close (they were apart of a narrow street) and were generating warnings every time. I wish I had this book back then.
