One pet peeve that gets to me is something that's done on a lot of commuter railways and S-Bahns, the 10/20 minute schedule. The schedule looks like:
2:10
2:20
2:40
2:50
3:10
etc, when it should be like this:
2:10
2:25
2:40
2:55
3:10
This minimizes waiting and allows for frequent service every 15 minutes..
What are your pet peeves?
It's supposed to be some kind of olive branch to suburbanites but they largely fucking hate transit anyway. What gets me is building rail parallel to an interstate so a huge amount of possible TOD space is taken up by the worst civil infrastructure ever built.
