You should probably drop by on the Belgian mailing list (osm.wiki/Mailing_Lists)
Jo (Polyglot) is active with maintaining bus routes, he uses data from de Lijn. I guess cooperating would be best, else you start destroying each others work.

Dear,
In the past I have been in a dispute with Polyglot on the busroutes.
But you can decide with this info: I, PeeWeeke, have taken all the local busses in Bruges a few years ago and mapped the entire network that way. (on the ground) He, Polyglot, has overwritten all busdata with his import of the data of De Lijn.
An import is fast and good if the data is recent … but it wasn’t. My estimate is that it was at least 5 years old. (Recent import seems to more accurate.)
I did mention old removed busstops and the long forgotten combined routes (80). I did contact Polyglot about this matter numerous times. I did explain that the information he uses is old. I even ask him to exclude the Bruges region out of his script as I would keep an eye on the situation on the ground.
So, I don’t feel like cooperating soon with a user who doesn’t check his sources.
Sorrry :(

Hmm
I also mapped a few bus routes in the past (but I found it hard to map a complete town), and AFAICS, Jo did leave these stops where I put them. So it looks like he did treat the existing data with care.
There were other problems though. Like some inaccurate positions for bus certain stops he added. But I had no idea there was a problem with data being outdated.
Of course, when a bus route is deleted, there’s no existing data, so I guess Jo just imported that.

I have been collaborating with Jo a lot and I have a total different impression on how he handles existing data. I’m pretty sure he is willing to listen to your arguments.
Busroutes are not imported. Jo wrote a script that generates a proposal based on the busstops. Before uploading, he tweaks the busroutes.
Even when you disagree with his method, it would be in the interest of OSM to use the same version of the public transport tagging scheme in all of Belgium. I don’t know whether this is a problem at this moment.
You won’t find a lot of (Belgian) people with an interest in busroutes via your diary I fear. Almost all discussion is going on on the Belgian mailing list. This is by far the most popular way of communicating with other mappers.
Anyhow, good luck with your quest.
regards

The data coming from De Lijn is refreshed 4 to 5 times per month, so I don’t see how it can be outdated. Anyway, after the ‘dispute’ with Peeweeke I’ve mostly left Bruges alone. More recently I’ve been checking and updating all the itineraries all over Flanders region though. It would of course be better that somebody with actual local knowledge does this.
That’s the reason for writing these and for creating some screencasts:
(osm.org/user/Polyglot/diary/28401) (osm.org/user/Polyglot/diary/34222) (osm.org/user/Polyglot/diary/34241)
I hadn’t realised I stepped on people’s toes back when I was adding/updating those thousands of bus stops and I apologise for the inconvenience caused. When stops were already present, I conflated them manually, mostly keeping the positions from the original mapper. The stops with inaccurate positions were the ones which couldn’t be placed based on the aerial imagery available. Each and every one of those stops has been checked manually, so it was certainly not a blind import.
I went digging in my mailbox. Apparently I resurrected a stop that wasn’t served anymore for a line that changed. Since this was in 2014 it surprises me that the current data of De Lijn wasn’t totally accurate at the time. When I hear about a change around here where I can check the ground truth, it’s always accurate.
Anyway, I hope the work I did on the conversion of the data and the scripts can still help you to keep the lines up to date. It’s all meant to make things easier, not harder.
The script to help with creating/updating the routes needs some more work to be really useful, but at the moment my interests are shifting toward Mapillary and their recognition of traffic signs, so I don’t know when I’ll continue to work on the itineraries or on the PT data.
