If its about the style of attributes, you could export the segment in OSM, than open the file in Maperative, than export as .svg file, than open and edit the layers in illustrator.
If you would like to edit, query and store OSM attributes to later on perform spatial analysis, the best way to do it is with ArcGIS: Arcmap. I have done it already with a plug-in included in this GIS suite. Check out the link.
