@4rch hi, as you probably know by now, we have a project in the area, so I went there during the weekend 11-12/7 and took the chance to move around and collect the speed limits that are somewhat critical to our research.

On capacities, I understand your point and I will not add them, however I kindly disagree. I think they are rather important for transportation modelling, transport management, evacuation management, understanding of how traffic behaves etcetera. It is a metric that can be measured (empirical capacity - this is how the highway capacity manual estimations were modelled) and depends on many road specific factors. As we have the measured flow in OSM (which might be deprecated given the temporal dimension of the measurement) I think we should also have capacities which are road specific and can provide valuable information to transportation related experts.

Anyhow, I trust you all that it is better for OSM to not include those characteristics. For us it is much easier to do it offline, as we already have that, but we wanted to contribute to this effort, thinking that it might be useful for others (i.e. transport engineers) who commonly use OSM (as for all the contents we add).

this is geodatas's coordinates, i'm trying to fix them right now

@4rch i used google maps until i understood that it was wrong, then continued with bing aerial but didnt change the google maps reference in my tags.
About the capacity matter, i will try to introduce the new tag i suggest and the way it will be computed according to the Highway Capacity Manual. "Highway capacity manual." Washington, DC (2010)

i begun with this, having collected some information from the local team. I am going to introduce the traffic_capacity and boundary=fire on wiki, if i don't get negative suggestions. osm.wiki/User:Petros_kleid#Source_of_Information

First, thank you very much for the suggestions and the help. It is rather unfortunate that due to a wrong tag ("capacity"), you undid the corrections I made. It also included all the correct max_speeds, and many road names that were correct as I have been working on that for quite some time. On the boundaries, I discussed with the Greek community as suggested in the link you sent and they suggested to use the following tag system: "type=boundary", "boundary = fire". However, I get a lot of conflicts when I try to upload the corrected changes. Is there any way to undo your changes and let me fix it?

No, maybe i just added the tag to that area. In general i have used other sources and I have to say I'm sorry because i had not read the terms of use before those edits

hi @wambacher and 4rch. I am petros and I work for CERTH research institute at Greece.
You are indeed right. We have not uploaded the data we wanted to according to the code of conduct (community buyin at least) and we are really sorry about that. Its not really an excuse, but we read a lot of information, however never found this page.
We will follow the procedure to make it happen formally. The uploaded data you see is not wrong.
The boundaries refer to the fires' departments jurisdiction in the area. We actually need it for a project we are working on, for Civil Protection at the area. The Capacities (although probably require an official tag like highway_capacity) are a way to model the maximum number of vehicles (per hour) for each link. This is also necessary in evacuation modelling.

Hope I shed some light to my uploads and it is better understood now.
Any suggestions would be highly appreciated as we are not very experienced with osm-josm
