The problem with all of this, is that one-way roads aren't really
one-way roads, they're only "do not enter" signs at one end of them.
Neither TTD nor the patch nor the vehicles know whether they are on a
one-way road or not, they only know that they're not allowed to enter
this tile from one direction.

Well, the pathfinding is really not at all equipped for judging routes
by their "quality". Length is the only variable it keeps internally,
and adding others would be... complicated.

Ah, I understand, and see that that might present a problem.... (o;


How, though does TT decide when a road should have pavement and
streetlights? Is there some property of the bit of road that is
flagged to tell it to display this? If so that would make Steve's
suggestion about speed limit of 50kmh in town more feasible to
implement, as the vehicle could just look at the sort of road it
travels along.... it must do something similar with bridges already?
In that case a flag could be added to one way roads to tell the
vehicle the sort of road it travels along....

Which is a load of ifs and buts, and probably wont work anyway!!

Anyone else with this problem? Or is it something in my configuration
perhaps? I've tried disabling some switches, but it still seems to
occur...

I think it's definitely someething to do with the one way roads.... as
if I take the one way criteria off the northbound carriageway, they
seem to overtake rather than just sitting behind the slowest.

The thing is, sometimes they do overtake, but sometimes not, and I
can't find any reason why they do/don't.....

That might explain it.... I have been creating every tile on the
motorway as a one way tile... in case any towns decide to add their
own entrances/exits while I'm not watching.....

*ponder* (!)

Chris

Looking at their behaviour on long straights of two way roads, I find
that the only place they don't overtake is when two slow vehicles in
front travelling at the same speed as eachother are spaced
sufficiently far apart to prevent the faster vehicle getting back into
the gap between them - the faster one just then tailgates the slower
one, rather than attempting an overtake... perhaps something similar
is happening if every tile is a one way road tile - the road vehicle
assumes that there isn't anywhere to pull in later...?

Actually, that would be useful for testing. Savegame+config files
please to the above address (and yes, it's valid).
