Is this it? http://www.openstreetmap.org/?lat=30.1044&lon=31.3386&zoom=14&layers=B00FTF The reason for the duplicate names on the major roads is that they are dual carriageways with the sane name on both the parallel roads. If you are rendering the data yourself this it would be possible to manually edit the data to remove the name from one carriageway and render the result. You should not upload this change to OSM though, the current data is correct. It is a limitation in the rendering which makes it appear twice. This is often less of an issue in the UK since major roads often have only a reference number (e.g. M25) and no name. There is special code in the renderer to ensure that this reference does not get displayed too often using the min_distance feature on the reference shields in the style file. Actually this feature might exist for road names as well but we don't use it at the moment. You could try setting the min_distance distance parameter for the primary/secondary road text in the osm.xml.
