Hey, welcome to OSM.

This cycle lane wasn't missing from Lombard Street.
It is already mapped using the cycleway tag here: way/49974586#map=19/53.34478/-6.24886

See cycleway=* for more about this approach to mapping cycle lanes.

Your approach of mapping a cycle lane/track as a separate way is common in some cases, but not typically done for a cycle lane like this which is an inherent part of the road.

I'm not here to convince to you choose one cycle lane/track mapping approach over the other, but to make sure you are aware of these two approaches.

Using both approaches for the same section of cycle lane/track should not be done as it results in duplication of information. So you should either keep the separetely mapped way, or change/remove the cycleway tags on the main road way.

The CycleOSM map layer is a handy way to see what cycle facilities have been mapped. The map layer can be changed in the menu on the right hand side of the screen on osm.org, if you didn't know.

Is there really an ATM here?

137611052 over 2 years ago

I'm not challenging your choice to map the footpath as a separate way. I respect that your approach is one of several acceptable approaches.

1. I don't see why OSM cannot accommodate mapping for both vulnerable and non-vulnerable classes of footpath users.

If you feel that a connection which somebody added between a footpath and road is unsafe for use by a subset of footpath users, then the solution is to tag it as such, rather than delete it.

I imagine that tags such as wheelchair=* and tactile_paving=* and kerb=* and lit=* would be useful when it comes to placing importance on the safety of vulnerable users?

For example if you deem an otherwise valid connection that somebody added unsafe to use because it involves a raised kerb, the solution is to map the raised kerb rather than deleting the connection.

2. In the example journeys I gave, there are crossings (with dished kerbs too) at the t-junctions of roads along the route (see See node/10754018268 and node/10754018234 for example of such locations), but you neglected to connect your footpath with the road at those locations.

It is when connections such as way/1180320076 are deleted that the separately mapped footpaths become the only option for the router. Consequently, if the separately mapped footpath isn't connected to the road at the applicable pedestrian crossing points along the way, we end up with these convoluted pedestrian navigation routes.

Have a good night.

Are you saying you want to ensure that the navigation is safe for vulnerable road users?

The walking distance for this trip is 224 metres (your change hasn't taken effect in routing terms yet) osm.org/directions?engine=fossgis_osrm_foot&route=53.27359%2C-6.35571%3B53.27375%2C-6.35324#map=19/53.27371/-6.35417

Once your change takes effect, the walking distance will increase by about 100 metres. This doesn't reflect the reality of what route a pedestrian would actually take to reach that destination from that origin.

Here is another example.
870 metres walking distance.
osm.org/directions?engine=fossgis_osrm_foot&route=53.27902%2C-6.35530%3B53.28299%2C-6.35576#map=17/53.28114/-6.35252

Same origin and destination as above, but in google maps: 450 metres walking distance.
https://www.google.com/maps/dir/53.2790614,-6.3552574/53.2830658,-6.3556906/@53.2812425,-6.3551525,17z/data=!4m2!4m1!3e3?entry=ttu

I would ask that when deleting the footpath connection that existed at the end of a cul-de-sac and creating a separate highway=footway alongside a highway=* road, you ensure that connections are added at junctions with other roads so that pedestrian navigation is not compromised like this.

137611052 over 2 years ago

Hi, please explain why you are removing connections between footpaths and roads?
This is detrimental to navigation use cases.

Hi, it's difficult to tell from your changeset description what you've done, but I've seen several cases of houses and housing estate roads/greens that were once covered by a residential area no longer being covered by a residential area where you are the last person to change those residential areas.

Can you explain why you are reducing the coverage of mapped residential areas to not cover greens and roads, in many cases cul-de-sacs, whose main purpose is for use by residents of the houses covered by said residential area?

Hi, the cycle lanes are already mapped on Rock Road, see `cycleway` tag e.g. way/4899944#map=18/53.30366/-6.18527

I found it mapped as a (non-mini) roundabout with one of the nodes on the circle being a mini roundabout tag on one of the nodes in the circular way. I wasn't certain that it was a mini roundabout so decide to simply delete the mini roundabout tag and keep the circular way.

Hi, if the English name is a correct translation it should be retained in name:en tag rather than deleted altogether.

Hi.
Why was the footpath between Killakee View and Ballycullen Drive deleted?

133644220 almost 3 years ago

Hi.
Why was the footpath between Kilakee Walk and Firhouse Shopping Centre deleted?

Thanks, I joined the list, but I'm waiting for another email to be sent in that thread, so I have something in my inbox which enables me to reply in the thread.

There are merits to each approach. The internationally practiced approaches are compatible with Ireland.
osm.wiki/Bicycle gives sufficient guidance.

131572095 almost 3 years ago

1. Yes, not good to have a conflicting approaches. I prefer tagging on the roadway for the most part, but to convince everyone to use one consistent approach, and replace everything that has already been mapped, is just not feasible.

2. Yes of course.

3. That is unfortunate. I haven't seen what it actually looks like on a Garmin, but I find it hard to lay the blame on osm data for a map readability issue.

4. To give some examples,
when I'm going to cycle to somewhere far away that I've never cycled to before, I sometimes find it useful to know which roads have cycle lanes/tracks, e.g. to plan a route that is faster/safer/less hilly/more direct/more enjoyable/[insert preference here].
Someone could also do this to optimise their commute to work/school etc.

I suppose someone could analyse the data using a tool such as overpass turbo to generate statistics about cycle provisions in a given area if they wanted to. This statistical information could then be used for many purposes.

*I meant to say "I wasn't informed of this agreement" in point 1.

131572095 almost 3 years ago

I'll answer with respect to the section north of Grand Canal heading past the petrol station on Adamstown Road. (It's hard to tell from your changeset where the other deleted sections (if any) are, since osm doesn't plot the location of deleted objects).

I'm not against having on-road cycleway tags in cases like Adamstown Road, but you just deleted the separately mapped cycle paths without replacing them with on-road cycleway tags.
That's why I posted my comment yesterday.

Anyway, to address your points:
1. When I started contributing to OSM, I asked the OpenStreetMap Ireland group on Telegram what the consensus was on which cycle track/lane mapping approach to use in Ireland. I was informed of this agreement, rather to follow the guidelines/examples given by OSM (wiki).
I would like to know more about this general agreement.

2. The cycle path is not still mapped as part of the road. North of the Grand Canal, where you deleted the separately mapped cycle paths, there isn't a cycle path mapped as part of the road.

3. Readability of the map depends on what application you are using to view the map?
If you want to show that there is only one bridge when there are several ways marked as bridge, you can add a bridge area/outline as per man_made=bridge
This approach is widely used around Dublin for example.

4. The crossing node at intersections with the cycle path and minor roads showed this need to yield. For example I added crossings where the path intersects the petrol station entrace/exit: node/9840063853
Admittedly I didn't tag every single minor road intersection node with a highway=crossing node, but anyone who wishes to add this extra level of detail is free to do so.

It was exactly because of the frequent yielding that I chose to use a separately mapped cycle path here.
With the on-road cycleaway tag there is no way to indicate that cyclists must yield at every junction. How can the on-the-road cycleway tag convey the need to yield to every minor road/driveway?

131572095 almost 3 years ago

Hi Dafo43,
Can you please give an explanation for deleting some shared cycle+foot paths around Adamstown Road?

Hi, your source of information for naming this road way/598950660 is copyrighted. It can't be used as a source for adding stuff in OSM.

My previous comment was supposed to contain this link aswell: way/1123737263

130305796 almost 3 years ago

Some of the roads you added don't seem to exist anymore.

If you look at the Bing aerial imagery (Apr 2021) and compare with Maxar, it looks like some of the roads were only built for temporary construction vehicle access, and removed once the north runway was completed.

These are the two roads I noticed. I didn't go through your whole changeset.
