I recently found that the OsmAnd app lets you adjust the safety of your bike routes, so you can prefer safety over distance.
When navigating, click the "Ride Style" button and choose "prefer unpaved roads." That name made me think it would find gravel/off-road trails, but it actually selects safer roads. In my experience this setting chooses the optimal routes--it's finding the same general path that I would pick based on local knowledge, and it found improvements where I could take a slightly different street for a few blocks to avoid cars!
Also, OsmAnd~ is available via Fdroid with all the paywalls removed.
Dude, no. I live off a dirt road and people treat it like a race track.
If they have an option called "prefer safer roads" then maybe, but if the app says unpaved, I'm going to assume that's what they are going for even if some of them are paved. They can "fix the glitch" server side any time they want without alerting your client side app.
Even in a city we have trails but if you use them to get places you will have to go by and large from trails to major roads. better to just stick to the bike lanes for commuting. trails are great for req though or if one fits in well with your commute but I would not have the route go out of the way to get to one.
I wouldn't recommend this option for inexperienced riders. Especially not on a city bike. I'm a somewhat advanced gravel rider and I switched this option off. To many times you can't continue without a machete. I'm in Germany BTW.
Sounds like it might vary. I don't have dirt roads near me, so it selects safe roads with slower traffic instead. Hopefully they can add a proper "prefer safer roads" option, but this works for me in the meantime.
I think the main thing for me in osmand was to uncheck "fastest route" option somewhere in the navigation settings. That was some terrible routing before i found out about that.
However i have been using brouter as the routing engine in osmand and never went back. You can use the brouter profiles from f.e bikerouter, or create your own. Haven't used the osmand internal engine in years so not sure how it developed in the meantime. You lose some details in osmand, road surfaces i think, but not important to me, i see it on the map, super happy with brouter engine.
