Does it still look like this image taken in Aug 2023?

Thanks for getting back to me. I'll edit it in the morning and add a longer explanation of the tagging here.

(Review requested)

That looks fine, thanks for updating OSM.

When you say "private", do you mean that the road is privately owned (unadopted), or only accessible with explicit permission (usually gated)?

If it's the former, appropriate tagging might be ownership=private + access=destination

Also, I note that you have given "Highway NSG data" as a source. Unless this is released under the Open Government Licence (OGL), it is unlikely to be suitable for use with OpenStreetMap. The terms of use for the NSG data released by GeoPlace only allows for personal use.

There are some open datasets available from Ordnance Survey under OGL, which include OS Open Roads and OS Open USRN.

Welcome to OpenStreetMap.

This was originally mapped as a footway.

Is what you are trying to represent here that it is a footpath between Seymour Place and private parking on Bryanston Mews West, and that it is private access due to the presence of a locked gate?

Hi @World_Winner

I visited Lindsell Street yesterday and made some initial edits with StreetComplete and SCEE. I also took some pictures which should be available on Mapillary soon.

On Lindsell Street to the SE of its junction with Plumbridge Street, there is a modal filter with two planters, removable bollard (locked) and "motor vehicles prohibited" signs (TSRGD diagram 619).

As I believe the council's own service vehicles are allowed to pass this point, I have tagged the bollard ( node/13344338810 ) with motor_vehicle=private rather than the motor_vehicle=no implied by the sign.

It would help if the current traffic order were available in The Gazette, but I can only find the experimental orders which preceded it and which have now expired. I suspect that the Westcome Society's website refers to a proposed change, but I'm not sure whether their website is a compatible source for OSM without explicit permission (which TomTom may well have, but I do not).

There is also something of an oddity on Lindsell Street to the E of the modal filter. There are old "weak bridge" signs with a 17 tonne (actual) weight limit. The bridge itself isn't obvious as the railway cutting for the former Greenwich Park branch line was filled in almost 100 years ago. This can be seen on old and out-of-copyright OS maps, e.g. https://maps.nls.uk/geo/explore/side-by-side/#zoom=19.7&lat=51.47332&lon=-0.01384&layers=168&right=osm

Please let me offer my apologies for taking so long to reply to you. I visited Lionel Road South yesterday evening, recorded imagery for Mapillary and made some initial updates using StreetComplete and SCEE.

Although Lionel Road South has (legally dubious) 5 mph signage, which would usually suggest an unadopted road ( ownership=private ), London Borough of Hounslow have made traffic orders for the road suggesting otherwise. The most recent of these are summarised in the notice at https://www.thegazette.co.uk/notice/4178860

For part of the road between the bollards and the mini-roundabout, I have changed the road from highway=tertiary to highway=unclassified and added motor_vehicle=destination + bicycle=designated access tags.

The bollards really ought to have the same access tags as the road beyond them, but as they are locked and cannot be passed without explicit permission I have added motor_vehicle=private with a note=*

The status of one-way working on Lionel Road South seems a little dubious. There is a one way sign (TSRGD diagram 652) at its junction with Kew Bridge Road and one way signs (diagram 606) opposite some of the service/pedestrian roads joining it. However, what I assume were "no entry" signs (diagram 616) near the mini-roundabout have been covered over and I saw a couple of motor vehicles being driven the "wrong" way. It may be worth contacting LB Hounslow's highways department for clarification and I suspect an enquiry from TomTom may get a faster response than from a private individual.

The Mapillary imagery is still processing, but should be available later.

changeset/177173491

In this changeset you added four railway=crossing nodes where a sidewalk crosses railway lines by what is obviously a *bridge*.

This may be the default "upgrade" offered by the Rabid editor, but it is also clearly and obviously wrong.

It also entirely defeats the purported object of adding separate sidewalks if you then add imaginary level crossings over railway lines, as routers are likely to assign a much higher cost to these.

Repaired in changeset/177170440

I saw that thread. It's unlikely that I'll have time next week, so hopefully it will all resolved before I do anything.

(Review requested}

Welcome to OpenStreetMmap and thanks for improving your local area.

There's one thing which you've added which might be better described using a different tag, which is the small park way/1465426695 . It's already within a park ( way/382655893 ) and looking at the aerial imagery, might leisure=pitch be a better fit?

Welcome to OpenStreetMap.

This was correctly tagged and changing it to a locked gate is clearly untrue. Removing the highway=secondary tag also breaks routing for all vehicles at all times. Reverted in changeset/177005172

If your routing software does not understand conditional restrictions in OSM, I suggest you raise a bug report.

What causes drivers to get fines is deliberately ignoring a TSRGD diagram 619 "motor vehicles prohibited" sign.

Thanks!

In the next few weeks I'll walk both loops, update what I can with StreetComplete and add the metal information=route_marker discs set into the footway.

Why did you feel it was necessary to redundantly and incorrectly add access=no here when it was already tagged with motor_vehicle=no and other access tags?

Adding access=permit here would imply that all transport modes, including pedestrians need a permit, routinely granted to everyone requesting it.

It's both a very car-centric way of tagging a modal filter and very unlikely to be correct.

As you haven't had the courtesy to reply and I am reasonably sure that access=no on way/1462752506 (implying a pedestrian prohibition) was incorrect, I've reverted this in changeset/176883372

There's at least one more of your changesets which requires a response.

Unfortunately your edit deleted part of the B3013 Minley Road. As this would break routing, I have reverted it in changeset/176874463

What were you trying to fix?

Set as access=private and name removed. It's included in OS Open Roads as an unnamed "Restricted Local Access Road".
