[OSM-newbies] Defining circular route bus on twoway streets

[Stefan Breunig]

It's important to note that this tool is only meant to find gaps in
routes, it doesn't draw bus routes. So the markers you see don't
denote "route starts here" but "here ends a connected >line<". It does
not work yet if the routes split: I've mapped train routes that split
on train stations (i.e. different platforms depending on direction)
and it adds markers on the nodes where the routes split.
If you want to mark that the bus only goes in the way's direction, add
it with role "forward", otherwise "backward" (these give the actual
driving direction, not whether the bus "comes from" or "goes to"!). If
you don't give it a role, it is assumed that both directions are fine.
Unfortunately I don't know about a map that renders routes apart from
Germany, but you still might want to have a look here:
http://www.öpnvkarte.de/?lat=50.11946&lon=8.68251&zoom=16 red lines
are bus, you can see line 36 going only into one direction).
If you want to make the route have an order, add the bus stops to it
and give them roles a la:
forward_stop_0
forward_stop_1
forward_stop_…
backward_stop_0
and so on. Very often the last forward stop and the "first" backward
stop are the same, I mark them as forward_stop_123;backward_stop_0.

Note that counting starts with 0.

Hope that helps.
Greetings
