OpenGeofiction
I’ve been working on Albert for a while, but I keep restarting because I can’t seem to get it right. My main problem is dealing with frequently changing altitudes. The place where I live is almost completely flat, so I’m not very familiar with how mountainy roads work. I’ve looked at Openstreetmap for inspiration, but I can’t really figure out the way the roads are designed. I’d appreciate any help, thanks. :)

I’d suggest looking at one of my favorite places to visit: Pittsburgh. Take a look at how the main thoroughfares (which themselves are not entirely flat) go around the main peaks in the city. Take Fifth and Forbes, for example, which go eastward out of downtown; then there’s Bigelow (PA 380) and I-376 to consider. The major roads will go largely around sharp inclines. Then notice that many streets that do climb elevation do so where the slope is more gradual or at wonky angles to make the sloping more gradual. Other streets simply just don’t connect, because the terrain is too difficult. One thing to think about is how tall the hill is. A 6% grade (6ft up for every 100ft forward) is steep enough to cause problems but doable. 10–12% grades exist in some places, but these are tough and should be very sparingly used if at all. I lived for a few years near a three-block 20% mean grade that was just impossible in the winter. Yuck.
