Give me a little certainty!
I don't think less buses and correlative decrease in frequency per se makes for poorer service; more so, it's the capricious and frustrating unreliability of the service that puts people off I think - a problem spawned from the lack of an anyway useful ETA at your stop for Mr Bus.
You're never quite sure if it's on its way or not, or if the driver has decided to leave early and screw up the inane timetabling that you've eventually figured out. So even though I like buses (especially sitting upstairs on double deckers, oh the thrill!), I eventually pretty much gave up on Dublin Bus for all but extreme circumstances. There were times when I questioned myself, like on the regular cycle with half my body weight in shopping on my back on a blustery day, but given the poor quality of service using the bike still seemed the more sensible option.
So I think if we want to get people to use the bus more, an intelligent timetabling service delivering reasonable levels of certainty is required so that even if you have to wait 20 minutes, at least you know it will be 20ish minutes. You can then go back to your friend's house, or go for a quick pint, coffee, browse in shop, whatever. It would make the worst thing about the bus (the uncertain wait at the stop) significantly less bad.
Has anyone of late been to a city with modern public transport infrastructure? Where you're given information like at Luas or Dart stations but for buses? I appreciate there are more stops for buses but I can't imagine the installation of a (sturdy) little digital box thing being overly expensive, and especially so relative to its benefits.
