I noticed that certain lines on AC Transit in Berkeley would routinely have the three back-to-back buses problem and wrote a post on it a while ago: http://andrewfong.com/blog/2009/11/12/bus-scheduling/ http://andrewfong.com/blog/2009/11/12/bus-scheduling/ Long story short, having a slew of people trying to board and disembark at the same time creates a lot of delay. It seems like the sort of thing you could address by having trailing bus(es) during peak hours. But if you're just naively running one bus every X minutes that stops at all stops along a given route, you'll inevitably have back up issues.
