I do know the names of some supervisors, but i'd rather not give them out, and I can't really answer the second.
I agree with you about the 116/7 change. It's not fair to not give Mount Hope Dr riders any weekend service without having to loop through Glenmont, and Green St ridership is just about 0, and Pearl St is a block away, so I don't think it's the end of the world for that. (The only problem is that the 7 might be too crowded, because Mt Hope gets significant ridership, but i'm not too sure about the 7's peak ridership levels.) Oh and one more problem, you have to do something with the northern end of the 116, because that end gets pretty good ridership in the peak direction.(The 129 might fix this problem, but i'm not sure yet) If it came down to it, I would rather have the 100 than the 9, but I think we should keep both. I've been meaning to talk to CDTA about this, because the 9 and 100 don't really serve the same areas. The 9 served Eagle, Delaware, Whitehall, Cardinal, Woodlawn, Partidge/Ontario, and Western, while the 100 only does Morton, New Scotland, and Quail. (Sorry if these street names don't make any sense to you), and the 9 had a significant amount of ridership, almost as high as the 100! Regarding BusPlus on the 10/12, I talked to CDTA about this, I don't think the 10 should get BusPlus, because unlike the 12, the majority of riders are going to their homes off of Western, and there isn't really a selection of say ten stops everybody gets on/off at. The 12 tough on the other hand, is a good candidate for BusPlus.
