Hi Felix,
No Johanns (v8) patch actually improves long distance routing (2-3 additional turns), while the remove bogus roads makes long distance routing worse for me (3-4 turns less). Sorry for the wrong text.
OK, thanks for clarifying that. My comments in the last message can therefore be totally ignored. Mind you, I still don't understand how the simplify way patch can work correctly. Perhaps it's time I actually tried it out.
I have no clue why the remove bogus nodes makes routing worse. v3 actually is great insofar as it allows several routable roads with different speed, but so far I have not been able to make such ways opposing oneways - but they are different speed. Currently playing around to find out how I can trick it into two opposing oneways (while the oneway is "artificial" in both directions in so far that I use incomplete rules to set it up).
The change that v3 introduced could be retro-fitted to trunk as it's essentially independent of the bogus node removal. Cheers, Mark
