A few more things:
- Please look at the latest dates. On the layer panel on the right you should see 07 (july), 08, 09. 10 is coming. We had some issues with 09 tiles we’re fixing now. You should notice that the detection gets better over time, especially with railways.
- We may actually just remove old months if you folks find the old ones confusing or not useful, and just always show the latest data
- Any feedback on the comparison (month-to-month) layers?
- We’re working on figuring out cyclists but it will take time
Generally speaking I think the “red tiles” are pretty good with the caveats about cyclists and (in the past) trains. It’s unfortunate we can’t open up GPS but there it is. Red tiles with one road in them are generally trivial to see what the problem is (as you can see in some of my prior examples). Red tiles with 20 roads need some sleuthing but generally are still pretty good. We can make smaller tiles to give a higher resolution grid, we’ll investigate this.
- “multiple other map providers” - I also looked at google and tomtom I think, purely to see if they agreed or not.
- cycle lanes - we route right now for cars. So if mopeds or cyclists get in the data, and use cycle paths, which they do a lot in NL, then we have problems. As I mentioned, we are working on a variety of solutions for this.
- GPS - it’s primarily privacy reasons and unfortunately a heatmap is not a sufficient obfuscator.
