OSM does not offer live traffic data, which makes it hard to use it for real life navigation. Does anyone know a project that takes care for this kind of data?
Are you from the USA? I'll assume so, because I've often seen this on HN/Reddit: a lot of people there seem to use Waze or other traffic info sources for getting around traffic. I want to know whether I'll be delayed so I'll check before a trip (and also during a trip if it's >2h), but I can recall driving around a jam maybe once in my life. It usually isn't faster, and that's assuming the byways/B-roads aren't congested as well, in which case standing in the jam is definitely faster. It sounds like spreading the load over multiple roads in the USA is a must.
Some of this is probably due to American vs European driving habits, with respect to long trips. It's hard to gain much by routing around congestion along a half-hour trip, but if you're going to spend half a day or longer then you definitely want to know when there's a wreck that makes it worthwhile to get off the interstate to avoid.
I'm in the UK. I have a half hour commute by car when there's light traffic. Congestion can easily add 10-15 minutes to that. There are at least three almost entirely independent routes that I can take to work that are the same without traffic so it's absolutely worth routing around it
So far only proprietary and not shared. https://maps.me/download/ has it (not in the offline mode obviously), mapbox does. Collecting the data requires to have 1000s of users sending their position and speed and OpenStreetMaps usual target audience is rather tracking-averse.
