Maybe the word 'transparent' is a bit confusing. With transparent I don't mean to omit line type 0x01 from the typ files at all. Like Henning said, you have to use a bitmap pattern without colours (=transparent) in the TYP file. On top of this, you use another bitmap with an arrow in the middle, for highways with oneway. This has to be a non routable line to avoid problems. For highways without oneway, you use another line type with a solid colour.
This isn't stupid, it works, only if you know what you are doing.
The only thing to watch out for is what your GPS uses when it pops up a routing instruction. On mine, it shows the routeable lines. When I set routeable lines as transparent in the TYP file, then the GPS ignores the transparency and used a 1px grey line instead, which was a bit confusing. It would be even worse if it just displayed the roads transparently as the routing instruction would just show a routing arrow, and no roads. In the end, I set the routeable way as a thinner version of the "display" road, using the same colouring. This way, when browsing the map you see the display road (because it's wider), but when the routing instruction pops up you see road styles that correspond to the overall map style, rather than thin grey lines. -- Charlie
