Hi Felix, yes, it is quite easy to implement that check, I already did it for oneways only (on my pc only) for the dead-end-check. The only problem are roads which cross tile boundaries, for those we have to disable the check because we will not know whether there are other roads on the other side of the boundary. Question is how to implement the change in attributes. As you know, the check occurs after the style was evaluated, so we'd need something like a special tag with a simple rule, maybe "mkgmap:dead-end-check-action=set road_class=&road_class - 2" The interpretation would be quite complex. The only other solution that I see is the two-pass interpreter that I already suggested, with a new rule file roads. I did not find a simple change to implement this, but I did not try long. Any ideas? Gerd Felix Hartmann-2 wrote
Would it be (without too much programming effort, nor too much computation time) possible to extend the current is connected check, to check for streets/lines connected to one side only? I would love to have road_class and road_speed lowered by 2- respectively -1 if this is the case....
Advantage would be a nicer routing graph I imagine - and thereby maybe a little improvement for long distance routing...
