this second mail is to think about other ways to determine the importance of a station without any specific tag. I have to say that I have no idea about how difficult it is to render a map and define render rules. So throw eggs if these ideas are not really thought through... One way to define the importance of a station could be to have a look a the route relations. How many different route relations are conected with the stop_positions of the station? Do these relations have a range of service tags (from commuter to long_distance?) Perhaps we could define a system to evaluate this. A different way could be the number of platforms: more platforms means higher importance. Either with the platform*s*-Tag (http://wiki.openstreetmap.org/wiki/Key:platforms). But it is not in really wide use. I don't use it, either. But there could be a way to determine the number of platforms through the stop_area relation. Of course, you can show me a lot of examples where a station with few route relations / platforms has higher importance than another station with more of these. But as far as I understand the question, the problem is a render problem in cases of collision. This happens with a small number of stations per case. So, we don't need absolute importance of stations here, but a relative ranking of these few stations. And I suppose, in most of these cases, a non-perfect method like the 2 I proposed, could work. What do you think?
