This is great - bookmarked! I see that while it does try to avoid busy roads, it often takes the road that's right next to the motorway (even when not strictly necessary - probably because it's shorter and has little traffic).
It'd be better to prefer roads that are further from busy roads. I understand that's very hand-wavey and probably super tricky to implement.
- Doctor_Fegg 7y agoIt would! As you say, roads (or cycleways) beside motorways are usually short, have little traffic, gentle gradients and often a prized position in a valley rather than lumbering up a hillside. Ideal cycle routes... apart from the motorway a few metres (/feet) away. I've got a page of notes on possible ways of fixing this - it is a hard problem. One possibility I'm toying with is a massive grid of "scenic value" for (say) each 0.01° x 0.01° square, so I could downrate the surroundings of motorways and uprate routes through (say) national parks.
- tasuki 7y agoCalculating "scenic value" sounds like a very good idea indeed! Plus points for points of interest and greenery, minus points for busy roads. Again, I understand it's not easy to implement :)
