Graphhopper VS valhalla

Well I think what he means is that we dropped the explicit support of Android and the example app with offline maps (Mapsforge), see this issue: https://github.com/graphhopper/graphhopper/issues/1940

But offline routing should still work on Android. But as you need JDK 1.8 support this will exclude a few older Android versions and devices, I think.

Graphhopper. It has an Android client that uses its web service. You can also try out the web app.

This is now fixed and deployed. See the route here and the specific fixed examples here. Note that you can still find the dangerous spots via clicking the "stop" icon below the route information multiple times. But this is likely a result of the bad cycling infrastruture as cycle.travel contains these short dangerous parts too and if you do such longer routes for Germany it does not happen.

I'd suggest refactoring to use a self hosted version of Graphhopper (https://www.graphhopper.com/open-source/ - they have a docker image you can use and pass in an OSM file to build a graph on) or OpenRouteService to limit your cost exposure to google.

Open Source. The routing server is open source too and geocoding too.

Valhalla is great (I've contributed a few patches and run it for a while)!

Also check:

if you attached a geolocation to each meeting that should be possible. either using the google maps API or a self-hosted graphHopper instance

I just improved the documentation for the map matching a bit. Maybe this also helps a bit.

Does Tesla even do their own routing? As far as I am aware they use https://github.com/valhalla/valhalla

Also see valhalla for an open source routing engine: https://github.com/valhalla/valhalla/

I use it to implement a solver for the Chinese Postman Problem for an open source routing engine named Valhalla (https://github.com/valhalla/valhalla/).

Love the idea of a blog post like this. I tried something very similar a couple weeks ago on a c++ project, both in hopes it might lead to an improved user experience, and also for others struggling to figure it out.

Note that Wahoo doesn't implement their own routing, the Bolt is using OpenStreetMap and Valhalla (https://github.com/valhalla/valhalla) to do routing. That's probably a reason why bugs are never fixed, it's not their code.
