I'm not very enthusiastic about this...
How would double track lines link up with single track for example?
My assumption was that the system would be incompatible; that the "rail" vehicles would, in fact, be special road vehicles, and would therefore not be able to interact with "standard" rail vehicles/track in any way.
My preferred solution is to make all roads one way, and to allow construction of two way roads by placing one way roads adjacent to each other automatically. Road and rail vehicles would have collision detection, so that both would be affected by congestion (maybe with some way of stopping road vehicles moving onto a level crossing if other side was occupied). Rails would then be placed directly over roads (on same alignment) - so you could decide to have on or off street trams depending on your budget and need to avoid congestion.
I didn't suggest this because it's basically been denied forever -- with good reason, I realize it would be a bear to impliment. Thus the request for something that might be an acceptable solution... My thinking was that if there was already code that could be adapted *easily*, or pretty easily.... maybe this would be allowed.
A side affect would be the need for city buildings to be allowed that are greater than 1x1 (else would be tiny in comparison to roads, that would be 2 tiles + wide. Another problem would be that rail station would have quite thin platforms compared to the current ones. Default station coverage would probably have to be doubled as well (and passenger generation balanced). Also no idea how road and tram, crossing with railways would be handled (possibly by allowing 3 ways per tile).
Just my opinion, and note - this would require a *lot* of work (even if it were decided this was the way forward), definitely a Simutrans 2 rather than 1 feature! However I would prefer for this to be implemented in a long term way rather than in an inflexible, short term way.
In regards to scale, check out the pak160 proposed scale...
This is an actual implementation of it:http://forum.simutrans.com/index.php/topic,4357.msg35847.html#msg35847
Also, here are my [...] attempts to show:http://forum.simutrans.com/index.php/topic,4349.msg35775.html#msg35775
I have two variants of the idea; the "four lane" and the "five lane".
The four lane is outlined with the above links, and consists of (left to right):
- 1/2 lane wide shoulder (which can be sidewalk, grass, shoulder, whatever)
- Single lane of traffic
- Single lane multi-purpose (center turn lane, center grass, extra "lane" space, tram)
- Single lane of traffic (see above)
- 1/2 lane shoulder (see above)
In other words, each full lane is 25% width of the tile...
BTW, for freeways, you can see in my screenshot -- although traffic only actually flows in the "right" of the three lanes, it's all aligned properly...
For the "five" lane system, it's as above, but the shoulders are full lane wide.(Above posted at 2006.11.26 - 15.50.52)_______________________________________ _______________
