A quick question about BusTimes - on the Vehicles by Route page (e.g.
https://bustimes.org/services/113-west-granton-pencaitland/vehicles), what do the numbers on the right mean? (1021, 1022)
Also do the numbers under the Trip column mean anything?
I think that's it trying to match the trip to the board number which is available via traveline data. It's not excellent at it.
If I had to guess the trip numbers continually increase with changes. They were all in the 239* range (some were occasionally 242) before and are now up at 246/7. I previously thought this number might've had more meaning but perhaps not. Obviously they'll have gone through many numbers throughout the process which were never used.
East Coast buses and Lothian Country start with 2467, then Longstone use 2467 into 2468, Marine vehicles are at 2468, Central are 2469 and 2470.
It suggests they do get grouped/completed/assigned in order of garages but I doubt it means anything in particular.
Individual routes all use numbers within a range but I'm not sure what the order is to it if any. Obviously if you look at an individual bus the trip numbers do not increment one by one so it must be done more generally.
In fact across the whole route the trip numbers actually decrease over the course of the day rather than going up!
I'm curious if these are just internal numbers that are used across their systems and whether the trips do have separate numbers assigned to them or not.
