Some time ago I have missed a good map of the main bus routes in Curitiba. The public transportation system in Curitiba is good, but there is no good map available online, even for the "biarticulado" lines.

I have mapped the path for almost all biarticulado routes. Next, the bus stations and stops need to be mapped.

Maybe in the future we can have all Curitiba bus lines (not only the main lines) mapped on OSM, and a good web frontend to see them. :)
