Routing via highway=service access=customers

[jodastephen]

I’ve got an example where the routing engine is choosing a route through a shop’s customer road rather than via the nearby public highway. I don’t think my tags are inappropriate, but feel free to comment:

OpenStreetMap

(The service road is closed overnight and wouldn’t be a good choice during the day either - it really is just for customers)

Would this route be the preferred from you? And do you think we should just make the customers-only road less likely to be picked or avoid it completely?

Note to self: there is also a customer access on the node: https://www.openstreetmap.org/node/6280188364 And there is also this related discussion about the destination access for foot and bike.

(thx for joda time btw !)

Yes, thats the route it should be offering. (Well strictly speaking, this route is the best as it goes via traffic lights and tactile paving / lowered kerbs rather than across two busy slip roads with neither of those things, but thats a different issue.)

I certainly think access=customers and access=destination should be lower priority than general public roads (assumed access=yes or designated).

More generally, I suspect there are cases where walking across an access=customers/destination area is fine and there are cases when it is not. I don’t think there is a general way to tell the difference via tagging at present - maybe it needs a new tag. In this case, the gate and the building_passage are extra clues, plus the fact that the public highway is a very similar distance.

thanks
