|yes||The public has an official, legally-enshrined right of access; i.e., it's a right of way.|
|no||No access for the general public. Consider using additional access (like foot=yes or bicycle=permissive, etc.) to indicate who can use the element. If only specific transport modes are forbidden, for example, at a vehicle no-entry sign, use a more specific restriction like vehicle=no or motor_vehicle=no over the general key access.|
|private||Only with individual permission|
|permissive||Open to general traffic until such time as the owner revokes the permission which they are legally allowed to do at any time in the future.|
|destination||Only when travelling to this element/area; i.e., local traffic only. NOTE: This restriction often only applies to certain modes of transportation (e.g., only to vehicles). Take care to use the right transport mode restriction; e.g., vehicle=destination when only vehicle traffic is restricted.
Sign text in different languages:
|delivery||Only when delivering to the element. For example motor_vehicle=delivery on a highway=pedestrian. Status: "approved"|
|customers||Only for customers of the element. If access is not open to any person willing to pay, consider using private instead. Membership clubs are generally tagged as private.|
|designated||A preferred or designated route for the class of traffic specified by the tag key, such as foot=designated, in general this means that there is a (explicit) sign saying something like "pedestrians allowed", or a pedestrian icon.|
|use_sidepath||Used to indicate that a mapped parallel way -that belongs to the same road- must be used instead (mostly acting as access=no with some exceptions). A road can legally consist of several ways, such as a single or dual carriageway with parallel tracks for cyclists, mopeds, pedestrians and/or equestrians. Used in countries where these classes must use specific parallel ways when present (following traffic rules, sometimes in conjunction with traffic signs). This tag should only be used to limit specific transport modes (e.g., bicycle=use_sidepath).|
|dismount||Permitted for some vehicle (or animal) only if you dismount. Mostly used for bicycle: Use bicycle=dismount when people are not permitted to cycle (e.g., through a graveyard) but are allowed to dismount and bring the bike. See Bicycle#Bicycle Restrictions. Note that bicycle=no is also commonly used where dismounting and pushing bicycle is legal.|
|agricultural||Only for agricultural traffic. Note a farmer's access track would be private rather than agricultural unless the track is open to any vehicle used for agricultural purposes. Status: "approved"|
|forestry||Only for forestry traffic. Status: "approved"|
|discouraged||A legal right of way exists (see yes) but usage is officially discouraged (e.g., HGVs on narrow but passable lanes). Only if marked by a traffic sign (subjective otherwise).|
|unknown||The access conditions are unknown or unclear. For the access key, where users might assume access rights by definition or some default, this makes it explicit that the actual situation is not known (since an absent access tag might also be mistaken by some users as being compliant to an assumed default). These tags should therefore not be removed without replacing them with a better alternative|
Tags of "access" group can be used for nodes, ways and areas. There are different priorities in OSM-community, where to put access tag: to area (usually it is a square, which have some specific conditions of access), to line (usually it is roads inside square) or to node (usually it is gate in barrier, which surrounds square, where there is a possibility to enter the area). Note that access tags mark legal status of territory and barriers and warning signs are only physical reflections of restrictions in area. In such manner, area with private status should have appropriate values, even there is no surrounding barrier or it is broken. Note, that different entrances can have different access values and different roads inside area can have different access values too. For example, we have area with permissive access - so we mark it with access=permissive. But there are several entrances, one of which is designated for all people, and other - only for persons, which have key. So we mark one entrance with access=permissive and other - with access=private. Another example - we have botanical garden with permissive access, which have roads, which are designated for public, and roads, which are designated only for staff of garden. In such case we have access=permissive at one roads and access=private (or access=no) at another.
When you are tagging some area, it is your decision, where to put "access" tags: to area, to entrances or to roads inside area (because nobody can bring you to add some tags somewhere), but removal of correct tags, which were put but someone else, is a mistake (and is close to vandalism). If you like to put tags to areas, do it, if you like to put tags to roads inside areas, do it, if you like to put tags to entrances, do it. But don't delete tags from type of elements, which you don't like.
Access can be tagged on facilities, typically including
- building entrances, which can be used to model that different entrances are for different groups of users,
- buildings themselves,
- amenities, often used on amenity=parking with restrictions to private (e.g. company employees only) or customers (people visiting a shop),
- leisure entities, such as leisure=sports_centre or leisure=playground where private describes a closed user group, e.g. members only or children of a particular school.
Access time and other conditional restrictions
- For a full description and more examples, please see the conditional restrictions page.
Restrictions may be limited to a particular time or day. Or they may limit the access for vehicles over a certain weight. Such conditions can be tagged as shown in these tagging examples:
- Only destination access is permitted during 8am and 5pm on Mondays to Fridays:
access:conditional=destination @ (Mo-Fr 08:00-17:00)
- Motor vehicles heavier than 5 tonnes may only access this street for the purpose of delivering goods:
motor_vehicle:conditional=delivery @ (weight>5)
Please note that the above tagging style can be used to replace the following time dependent restrictions. It has been suggested that they be deprecated and should therefore no longer be used. date_on=*, date_off=*, day_on=*, day_off=*, hour_on=*, hour_off=*. Also note, that using of conditional tag assumes overt indication of value, which mostly suites as a default value. For example, if access is open on one part of day (on this part of day access=permissive) and is closed on other part of day (on this part of day access=private), we have a situation, when we should mark the object with a tag access=permissive or access=private. There is no concrete, precise and universal algorithm to define, if we should use permissive or private in concrete situation, but we can definitely say, that in such case we can't use access=yes (or not use tag access at all), because access=yes (or absence of tag access) means round-the-clock open access for general public.
Size and statutory restrictions
A number of statutory restrictions based on height, width, weight, etc. can also be defined. A assumed units are the appropriate SI unit and should be specified without any suffix. For lengths use metres, for weights use metric tonnes and for times use hours. Decimal numbers should include a decimal point. Exceptions include speeds which should be in mph in places where speed limits are defined in these units and times which can include a suffix of 'days' if appropriate.
- maxaxleload=* - The legal maximum axleload in metric tonnes.
- maxheight=* - The legal maximum height in metres
- maxheight:physical=* - The maximum height in metres
- maxlength=* - The legal maximum length in metres
- maxspeed=* - Specifies the maximum legal speed limit on a road, railway or waterway (km/h by default, mph where specified)
- maxstay=* - Maximum time you are allowed to stay somewhere. (maximum parking time)
- maxweight=* - permissible maximum actual weight
- maxweightrating=* - Legal access restriction for vehicles with a max allowed weight above the specified weight in metric tonnes.
- maxwidth=* - The legally restricted maximum width of a vehicle (also note width=* for the physical width of the entire road.)
- mindistance=* - minimum trailing distance, often as mindistance:hgv=* on old bridges or in tunnels
- minspeed=* - Specifies the minimum speed limit on a road, railway or waterway.
- maxdraught=* -
Ways may have different access restrictions for each direction. The most simple case is a way designated as a oneway road:
- Driving is only allowed in the direction of the way.
- Driving is only allowed against the direction of the way. If possible reverse the direction of the way and tag with oneway=yes.
- Not normally used, as two-way traffic is the default. Use only where another tag (such as highway=motorway) implies oneway=yes.
For more complex direction dependent restrictions, the postfixes
:forward can be used on the keys, for example:
- When cyclists are allowed to travel in both directions on a oneway street (but no lane is present).
- When a road has a oneway cycleway next to it that must be used, and a cyclelane in the other direction.
Also in use when cyclists are allowed to travel in the opposite direction:
- Only if a separate lane exists.
- Only if a separate track exists.
- Consistent with tags based on conditions. Note: This was previously tagged as "bicycle:oneway=no", but this is deprecated.
The oneway tag can be translated (for routing purposes) to this generic system as follows (oneway restrictions presumably do not apply to pedestrians):
- Heavy good vehicles are not allowed on the leftmost lane of a road with three lanes.
- Buses are not allowed on the leftmost lane of a road with three lanes in forward direction. The rightmost lane is a designated bus lane.
