Parking only in one direction possible

I have encountered a problem when it comes to mapping parking spaces.

My given example does only allow parking coming from one direction, as else you are sort of „soft locked“ in your vehicle. You can‘t open the door to exit the vehicle, if you happen to try to park from the other direction. The spaces are marked, but marked too close to the buildings/walls.

The drivers seat cannot be at the side of the buildings.

So I ask if it is possible to map a street as one-way specifically for parking in there. Basically I am searching for a key like parking:oneway ;)

It’s physically possible for the driver to disembark from the front passenger door. This should not be *oneway= for legally. Not prohibited.
Is sidewalk=no for the orientation=parallel not enough? Is it actually a width= question, as bigger cars could have difficulty in other sized spots? There are doors with vertically opening movements (fully or partially), and even some driver sliding door, which may be usable there.

What it be possible to link to that specific example? The context might help people answer (they can look at other tags - oneway, width etc., and can also look at imagery).

Is parking:side:direction=head_in or parking:side:direction=back_in as documented in the street parking wiki page under taggingSpecial rules on parking direction what you are looking for?

… specifically parking:left:direction (98 uses) and parking:right:direction (101 uses)?

They seem to be for perpendicular and diagonal parking though (example). Perhaps use taginfo to search for tags used with parallel parking?

The question doesn’t seem to have regulations. Only driver behavior. It’s physical usability, not legal rules.

The street is a classic residential two-ways street, but the parking is only on one side and only possible if the car is driving on the side the parking spaces are.

But the question is: Are you talking about physical difficulty, or there are signposted rules? The former depends on each vehicle and spot. Sometimes such a spot is slightly wider, and one may be able to park and exit at driver side, then it’s complicated.
As I said, can vertically opened door cars, or sliding driver door van park at there or similar situations? If yes, it’s not universal.

It is theoretically possible to park also from the other side, but you will need a very small vehicle like a hyundai i20 or original mini.

I’ll make a photography soon within half a week or so ;)

I’ll also link the roads, but they are probably a lot more than I orignally thought within the area. I’ll need to check ^^

This sounds like parking:right:orientation=diagonal plus parking:right:direction=head_in (or the appropriate swapped variants).

Why :smirking_face: … parking is parking. what you are trying to bring forward would introduce complexities to the OSM platform.

What does =diagonal have to do with this? You are misunderstanding.
=parallel doesn’t matter whether it’s =head_in or =back_in

Since I won’t be within the area again soon, I’ll try to reconstruct it with paint and a screenshot from iD-Editor.

There are at least four roads where I have seen this problem: Way: ‪Alpengartenstraße‬ (‪12816672‬) | OpenStreetMap , Way: ‪Mariabrunner Straße‬ (‪16289098‬) | OpenStreetMap , Way: ‪Forstmeistergasse‬ (‪12816371‬) | OpenStreetMap and Way: ‪Alois-Behr-Straße‬ (‪12816701‬) | OpenStreetMap
if you are using aerial imagiary you’ll need to use the newest background layer: Vienna: Orthofoto (aerial image)

Here is how that would look like in Practise:

It is practically impossible to get out of the car if you happen to try to park from the wrong direction, so people that use GPS Navigation that directs them on the “wrong side” to search a parking space would have to drive the street along and to turn around so they can exit the vehicle at the parking space. So for visitors or people living in that street it is a defacto one-way street, even though it is not signed.

Friends close to me have noticed this and have asked me if something could be done to make the navigation software act correctly when visitors of them search for a parking space.

The next image is how you would be parking if you parked correctly (as seen above)

At least in German traffic law, the rule requiring vehicles to drive on the right implies that you are only allowed to park on the right-hand side of the road “in the direction of travel.” I would be very surprised if the situation were any different in Austria.

So you’re not allowed to park with the driver’s door facing the wall here anyway (unless it were a real one-way street, but you said it isn’t).

In fact it is legal here, as it is not forbidden, unless:

RIS - Straßenverkehrsordnung 1960 § 7 - Bundesrecht konsolidiert

(4) Beim Zufahren zum linken Fahrbahnrand und beim Abfahren vom linken Fahrbahnrand dürfen andere Straßenbenützer nicht gefährdet oder behindert werden. Bei starkem Verkehr, auf unübersichtlichen Straßenstellen, auf Vorrangstraßen im Ortsgebiet und auf Fahrbahnen mit Gleisen von Schienenfahrzeugen ist das Zufahren zum linken Fahrbahnrand, außer in Einbahnstraßen, verboten.

This should still be valid, as it is still (in year 2025) tought to students in driving schools. (yes it is)

And since none of the 4 examples is a priority road, has rails or heavy traffic it means it is legal.


But the questions should more be: How could it be mapped that it is physically not possible to try to park from the wrong direction, or whether OSM should even contain this information.

How does the rule imply that?

It is physically possible to park from “the wrong direction”. You just need to exit from the passenger side door. Or, if you have a Twizy, you can park front-in or rear-in.

It also explicitly states that in §12:

For parking, the hard shoulder on the right – which includes parking bays along the carriageway – must be used if it is sufficiently paved; otherwise, you must pull over to the right-hand edge of the carriageway. This generally applies even if you only wish to stop; in any case, you must keep to the right-hand side of the carriageway.

Thank you. An explicit rule is very understandable.

Map the wall right next to the roadway. Map roadway width. You could add shoulder=no and verge=no. These are the physical verifiable properties here.
