Seems so? https://traffxml.gitlab.io/app-navit.html https://traffxml.gitlab.io/app-navit.html (also at https://www.navit-project.org/ https://www.navit-project.org/ apparently) https://traffxml.gitlab.io/ https://traffxml.gitlab.io/ seems to be a better landing page than the submission URL which just contains a bunch of loosely organized git repositories.

I am looking for the other direction. What the above describes is Navit receiving traffic information, I want Navit (or ideally, an even simpler app) to submit data to an open source traffic server. The idea is to crowd-collect traffic information just like how Google does it (monitoring speed of those who have their Android phones with Google GPS services on, but out of willing participants): basically transparent to the users (other than them having to install the app and then figure out a way to allow them to run it in the background on recent Android systems :). I'd feel much more comfortable submitting to a server where I've got full control of the data it emits (I can better ensure it retains my privacy by using new route ids often, for instance).

  Maybe this is more what you're looking for? https://www.openstreetmap.org/traces https://www.openstreetmap.org/traces Seems to be public traces the public are submitting willingly. What's missing is a service to integrate that data into the map view/routing, unless this is exactly what Traff integrates as well, unsure.

    Nope: those are not anonimized nor real time. Basically, Google knows a road is congested by having dozens of people (with their Android phones and location services turned on) slow down on a road where they would usually go much faster. I want the same thing with better privacy guarantees and that's open source and free to use.

      You’re looking for a sensor fabric that can track mobile devices with their signal strength and time of flight, as it’s likely you’ll never get enough critical mass of devices to do this with open source apps. This allows you to distill traffic velocity without device access or onboard device telemetry being shipped. Google can do this because they control the Android and Google Maps ecosystem. Without such scale, you’re at a significant disadvantage.

        Yes, I understand that. But the same variation in resources holds true for eg. Google Maps vs OpenStreetMaps, yet OSM is still sometimes much better than GMaps. And Google also crowdsources their data even with all the resources at their disposal. Whether there'd be a critical mass depends on a lot of factors, and it's a safe bet that there wouldn't be one. But I would wish us to try :) FWIW, there would huge commercial interests for other parties to provide these, eg all the taxi and delivery services could have their drivers participate, while allowing their app developers to integrate that traffic information into their own route estimations and optimizations.

        Btw, your suggestions make me think of another interesting approach that local governments could take. Instead of devices reporting themselves, we could have hotspots observing mobile phone signals (eg. integrate them into traffic lights): we'd need at least 3 nearby for triangulation, and they'd have to be everywhere, so it would require government support and desire to provide traffic info for the public.
