    Just wondering does anyone if DB or The NTA have a performance based index based on each bus route. If so what would be best and worst performing route on the DB in terms of punctuality, reliability etc. Does DB, CIE or The NTA have a league table or a points based system as to which routes are performing best or would there be a depot based system for example would routes based in say Ringsend out perform the routes based in say Harristown. If so what would be the best and worst performing routes?

    If this system is not currently in place surely it would need to be introduced espeically with the routes being tendered out to Go Ahead.

    Considering how often you get phantom buses showing as moving according to the RTPI system, I doubt if any data provided by DB would be worth using. If a scheduled bus does not leave the terminus (not late, does not run at all) but after the scheduled departure time it still shows up on RTPI, even on a bus stop that's over 30 minutes from the terminus, it suggests that DB is fiddling the numbers so they're telling the NTA that their routes are more reliable than they really are.

    I accept that on occasions they can't run a particular service because of staff shortages, fleet breakdown, delays caused by traffic etc. but if a service isn't going to run, FFS pull it from the RTPI system so that people don't wait like fools for a bus that claims to be on the way for all of 45 minutes after the scheduled departure time, only for it to disappear from the display 2 minutes before it's predicted arrival time. Then you complain and they copy & paste a generic (PFO) reply.

    Most operators would have a (automated vehicle location system) AVLS: https://en.wikipedia.org/wiki/Automatic_vehicle_location - it's what feeds things like RTPI.

    Depending on the particular system, it would have the features you suggest. As to whether there is comparison across routes and other high level management is another matter, as coylemj indicates.

    Dublin Bus used to commission a company to do an on-street survey. I looked at this some years ago and it did not seem to be a very rigorous process. I don't know if anything like this is done anymore.

    AVLS is not really accurate enough to do this survey work. The RTPI system, as I understand it, was only ever expected to be 90 percent accurate (I think this is shocking.)
