Popular routes/ heatmap

[Ben Listman]

I'm looking for something that shows popular routes for cycling in the city.

Using origin/ destination data with Google's Routes API could work I think, but I thought maybe someone had already done this sort of thing. I just didn't see it doing a quick search.

I know Strava published a heat map six-ish years ago.

Anyone know of something like this that's more recent? Any other suggestions?

Thanks!
