Cycleway smoothness

[slackline]

Hi,

I was notified by a friend of the following project that attempts to use data captured from cycling to estimate the quality, in terms of smoothness, of a given cycle route...

https://github.com/schienenersatzverkehr/byke

It's a bit dated as its written in Python 2.7 which has reached its end of life, but it made me think of two things, the first being BRouter, the second being how it might be incorporated into OSM/BRouter in some manner.  I know there isn't currently tags in OSM to define the quality of a way, nor is BRouter able to use such information (since it doesn't exist).


I should note that I've not yet tested the algorithm in anyway and do not have the requisite skills to translate it into an application of its own (I'm a Data Scientist and have work/life that prevents me from having sufficient time to learn to write applications for smartphones).

Just thought I'd flag it up on the off-chance someone can use it as its an interesting idea. I'd need to purchase a mount for my phone and try capturing and processing some data myself to find out if the methods are reasonable and worth pursuing further.

Hey, it does seem that there's a key for cycleway:smoothness = * as per this part of the wiki: https://wiki.openstreetmap.org/wiki/Key:cycleway#Supplementary_details

I have no idea how widespread it's use is, and of course it's a mapper entered field that would be very subjective. But it would be great for routing apps. An app could have a preference for smoother routes, which would be neat.

For a couple of years now I have been using the surface and smoothness tags for cycling infrastructure and minor roads where I map (Padova, Italy). And others do so as well.

In my understanding, surface=* and smoothness=* is usually mapped and profile evaluated for highway=* themselves, not for  cycleways as highway feature ( highway=*  cycleway=*)

Cool I hadn't realised/searched to see if there were tags for smoothness thanks all for the heads up on that.

It would be interesting to see how the subjective ratings (https://wiki.openstreetmap.org/wiki/Key:smoothness) compare to the scores predicted by this algorithm.

Maybe I'll ask for a bike mount for my phone for xmas and find out.

I revoke my comment seeing they have it.

It least cycleway:surface= is considered by Brouter.
