Ok so for this one
Here’s what I found in no particular order:
- There are mopeds (I think) using Kleinpolderkade but not super many of them. We do filter cyclists with some success. Mopeds are harder :-/
- The car park in Piet Cottarstraat has many GPS traces going through the middle of it, right down the middle of where satellite shows the car park recently. It looks like either some GPS is snapped to a map with a road through the middle (which is possible but unlikely from looking at the maps), or, there was road work and it was redirected.
- The one way streets in OSM on the West side of the A13 don’t agree with multiple other map providers. No idea who is right without being on the ground.
- There’s a chance that the two living streets from the car park to Ludolf de Jonghstraat aren’t being routed against correctly, we will check.
Zooming around one of the links provided:
For here:
That building(?) at the SE corner of the roundabout is full of vehicle traces. On the satellite I looked at it looks like a rough grass square. From the GPS it looks like a car park or loading docks.
Here’s another
OSM has a cyclepath with a access gate to the east of what looks like a house. From GPS, this looks like a lot of cars with no gate and should “really” be a road. It could be moped riders but looks like cars. It doesn’t look like anyone stops for the gate, if it’s there.
From another link, looking at the red areas here:
If you look at satellite there’s lots of access roads missing around the buildings and connecting to what looks like a taxiway (which I can see a lot of vehicles use).
Similarly:
has roads to the northern buildings, (road or highway:track, or something but there’s no road there in OSM)
For this one:
the “space” in that tile at the top right that runs roughly NW/SE is a heavily trafficed “road” from the GPS.
On the other hand, this one is a complete puzzle to me:
This is also another slightly puzzling one:
It looks to me like a lot of people take mopeds (or something) past that building in this red tile. Filtering out high speed cyclists vs. low speed mopeds is not trivial.
Hope this was useful we will discuss these more internally and see if we can figure out solutions. More feedback is welcome!
