Maybe slightly better, but still not great. It's skipping the eastern part of the Sarphatistraat. Also it struggles with street names and encourages you to only type a town, which isn't very useful.

I like that it allows you to choose between paved, gravel or any. Although gravel may still be too limited for some; mountainbikers like dirt tracks, and I've had Google Maps send me through loose sand that would probably require a BMX.

Oh, good spot. Fixed. OSM geocoding is better than it used to be - I used to just say "town" because streetnames were partial, but they're pretty good now.

If you have a start and endpoint that should use Sarphatistraat but don't, I'm all ears. (It's my site!)

    That's an amazingly quick fix!

    Try "Feike de Boerlaan" to "Vondelpark". I would expect the trip to take the Czaar Peterstraat and then the Sarphatistraat, but instead it takes the Panamalaan, Zeeburgerdijk, Mauritskade, and only switches to the Sarphatistraat at the Weesperplein, which I think is also the point where the Sarphatistraat changes from a bike street to a regular street with a bike lane. Although it later switches back to bike street again yet the route stays on the bike street.

    So I have no idea what's going on with that first part of the Sarphatistraat. It's a really nice route, yet all apps hate it.

      Really interesting test case - thanks!

      cycle.travel's scoring for the two routes differs by 0.4% so it's very close. In OSM data terms, the challenge is that there's no particular special tagging for the Sarphatistraat - it just gets classed as a "cycleway", same as the route along Mauritskade. Plus there's a couple of very slight advantages for the Panamalaan (which is tagged as part of a designated longer-distance bike route) and the Zeeburgerdijk/Mauritskade (which are beside water so get a scenic uplift).

      I might look at doing some Amsterdam-specific routing tweaks: I doubt the longer-distance bike route consideration should be relevant in this case, for example.
