Usage

Main article: Highways

The key highway=* is the main key used for identifying any kind of road, street or path. The value of the key helps indicate the importance of the highway within the road network as a whole. See the table below for an ordered list from most important (motorway) to least important (service).

See Highway:International equivalence for how different countries apply these tags to their own road networks.

Note that highway=* distinguishes roads by function and importance rather by their physical characteristic and legal classification. Usually these things are highly correlated, but OSM is not obligated to copy official road classifications.

This key is also used for features like bus stops, service areas, pedestrian crossings and other highway related things (see below).

Note that while it can be confusing this key is also used for tagging paths, lamp posts, bus stops, not only major roads.

Examples

We have about a dozen-and-a-half examples each of urban and exurban tagging, with photos.

Roads
This group lists the 7 main tags for the road network, from most to least functionally important for motor vehicle traffic.
highway	motorway		A restricted access major divided highway, normally with 2 or more running lanes plus emergency hard shoulder. Equivalent to the Freeway, Autobahn, etc..
highway	trunk		The most important roads in a country's system that aren't motorways. (Need not necessarily be a divided highway.)
highway	primary		The next most important roads in a country's system. (Often link larger towns.)
highway	secondary		The next most important roads in a country's system. (Often link towns.)
highway	tertiary		The next most important roads in a country's system. (Often link smaller towns and villages)
highway	unclassified		The least important through roads in a country's system – i.e. minor roads of a lower classification than tertiary, but which serve a purpose other than access to properties. (Often link villages and hamlets.) The word 'unclassified' is a historical artefact of the UK road system and does not mean that the classification is unknown; you can use highway=road for that.
highway	residential		Roads which serve as an access to housing, without function of connecting settlements. Often lined with housing.
Link roads
highway	motorway_link		The link roads (sliproads/ramps) leading to/from a motorway from/to a motorway or lower class highway. Normally with the same motorway restrictions.
highway	trunk_link		The link roads (sliproads/ramps) leading to/from a trunk road from/to a trunk road or lower class highway.
highway	primary_link		The link roads (sliproads/ramps) leading to/from a primary road from/to a primary road or lower class highway.
highway	secondary_link		The link roads (sliproads/ramps) leading to/from a secondary road from/to a secondary road or lower class highway.
highway	tertiary_link		The link roads (sliproads/ramps) leading to/from a tertiary road from/to a tertiary road or lower class highway.
Special road types
highway	living_street		For living streets, which are residential streets where pedestrians have legal priority over cars, speeds are kept very low.
highway	service		For access roads to, or within an industrial estate, camp site, business park, car park, alleys, etc. Can be used in conjunction with service=* to indicate the type of usage and with access=* to indicate who can use it and in what circumstances.
highway	pedestrian		For roads used mainly/exclusively for pedestrians in shopping and some residential areas which may allow access by motorised vehicles only for very limited periods of the day. To create a 'square' or 'plaza' create a closed way and tag as pedestrian and also with area=yes.
highway	track		Roads for mostly agricultural or forestry uses. To describe the quality of a track, see tracktype=*. Note: Although tracks are often rough with unpaved surfaces, this tag is not describing the quality of a road but its use. Consequently, if you want to tag a general use road, use one of the general highway values instead of track.
highway	bus_guideway		A busway where the vehicle guided by the way (though not a railway) and is not suitable for other traffic. Please note: this is not a normal bus lane, use access=no, psv=yes instead!
highway	escape		For runaway truck ramps, runaway truck lanes, emergency escape ramps, or truck arrester beds. It enables vehicles with braking failure to safely stop.
highway	raceway		A course or track for (motor) racing
highway	road		A road/way/street/motorway/etc. of unknown type. It can stand for anything ranging from a footpath to a motorway. This tag should only be used temporarily until the road/way/etc. has been properly surveyed. If you do know the road type, do not use this value, instead use one of the more specific highway=* values.
highway	busway		A dedicated roadway for bus rapid transit systems
Paths
highway	footway		For designated footpaths; i.e., mainly/exclusively for pedestrians. This includes walking tracks and gravel paths. If bicycles are allowed as well, you can indicate this by adding a bicycle=yes tag. Should not be used for paths where the primary or intended usage is unknown. Use highway=pedestrian for pedestrianised roads in shopping or residential areas and highway=track if it is usable by agricultural or similar vehicles. For ramps (sloped paths without steps), combine this tag with incline=*.
highway	bridleway		For horse riders. Pedestrians are usually also permitted, cyclists may be permitted depending on local rules/laws. Motor vehicles are forbidden.
highway	steps		For flights of steps (stairs) on footways. Use with step_count=* to indicate the number of steps
highway	corridor		For a hallway inside of a building.
highway	path		A non-specific path. Use highway=footway for paths mainly for walkers, highway=cycleway for one also usable by cyclists, highway=bridleway for ones available to horse riders as well as walkers and highway=track for ones which is passable by agriculture or similar vehicles.
highway	via_ferrata		A via ferrata is a route equipped with fixed cables, stemples, ladders, and bridges in order to increase ease and security for climbers. These via ferrata require equipment : climbing harness, shock absorber and two short lengths of rope, but do not require a long rope as for climbing.
When sidewalk/crosswalk is tagged as a separate way
footway	sidewalk		Sidewalk that runs typically along residential road. Use in combination with highway=footway or highway=path
footway	crossing		Crosswalk that connects two sidewalks on the opposite side of the road. Often recognized by painted markings on the road, road sign or traffic lights. Use in combination with highway=footway or highway=path. Useful information is presence of tactile_paving=*, wheelchair=* suitability and kerb=* represented as a node on the crosswalk way.
footway	traffic_island		The way between two crossings, safespot for pedestrians, has micromapping characteristics as a detailed alternative to =*. Use in combination with highway=footway or highway=path.
When sidewalk (or pavement) is tagged on the main roadway (see Sidewalks)
sidewalk	both | left | right | no		Specifies that the highways has sidewalks on both sides, on one side or no sidewalk at all
When cycleway is drawn as its own way (see Bicycle)
highway	cycleway		For designated cycleways. Add foot=*, though it may be avoided if default-access-restrictions do apply.
Cycleway tagged on the main roadway or lane (see Bicycle)
cycleway	lane		A lane is a route that lies within the roadway
cycleway	opposite		Deprecated variant for ways with oneway=yes where it is legally permitted to cycle in both directions. Replaced by oneway:bicycle=no.
cycleway	opposite_lane		Deprecated variant for ways with oneway=yes that have a cycling lane going the opposite direction of normal traffic flow (a "contraflow" lane). Replaced by oneway:bicycle=no + cycleway:left=lane/cycleway:right=lane + cycleway:left:oneway=-1/cycleway:right:oneway=-1.
cycleway	track		A track provides a route that is separated from traffic. In the United States, this term is often used to refer to bike lanes that are separated from lanes for cars by pavement buffers, bollards, parking lanes, and curbs. Note that a cycle track may alternatively be drawn as a separate way next to the road which is tagged as highway=cycleway.
cycleway	opposite_track		Deprecated variant for ways with oneway=yes that have a cycling track going the opposite direction of normal traffic flow. Replaced by oneway:bicycle=no + cycleway:left=track/cycleway:right=track + cycleway:left:oneway=-1/cycleway:right:oneway=-1.
cycleway	share_busway		There is a bus lane that cyclists are permitted to use.
cycleway	opposite_share_busway		Deprecated variant for ways with oneway=yes that have a bus lane that cyclists are also permitted to use, and which go in the opposite direction to normal traffic flow (a "contraflow" bus lane). Replaced by oneway:bicycle=no + cycleway:left=share_busway/cycleway:right=share_busway + cycleway:left:oneway=-1/cycleway:right:oneway=-1.
cycleway	shared_lane		Cyclists share a lane with motor vehicles, there are markings reminding about this. In some places these markings are known as "sharrows" ('sharing arrows') and this is the tag to use for those.
busway	lane		Bus lane on both sides of the road. (See also: Parallel scheme for bus/psv lane tagging lanes:bus=* / lanes:psv=*)
Street parking tagged on the main roadway (see Street parking)
parking:left / :right / :both (hereafter: parking:side)	lane | street_side | on_kerb | half_on_kerb | shoulder | no | separate | yes		Primary key to record parking along the street. Describes the parking position of parked vehicles in the street.

Assumptions

Unpaved road of major importance, example of highway=tertiary on Highway Tag Africa

Forestry road not used as link between settlements, correctly tagged as highway=track + surface=asphalt + tracktype=grade1

Only highway=motorway and highway=motorway_link indicate quality. Other road types, from trunk to tertiary to residential, service, path, footway, cycleway or track, do not imply anything about road quality, only importance and intended main use.

In a region with poor infrastructure, a road of highest importance, forming the main road network there, should be highway=trunk, regardless of being a high-quality wide asphalt road or a low-quality narrow track worse than highway=service in other regions. Examples include the Kolyma Highway (P-504) and the Vilyuy Highway (A-331) in the Russian Far East, and a long stretch of the Trans-Amazonian Highway (BR-230) and BR-319 in the North Region of Brazil.

A typical highway=primary can also vary drastically between different regions on the planet. Some highway=primary roads in parts of Africa, Asia, South America, Canada, Alaska, Australia and Iceland are unpaved. Examples include the Anadyr Highway (A-384) in the Russian Far East and the Juba–Rumbek Road (route 69) in South Sudan.

It is highly recommended to add tags describing road quality, such as surface=*. In one region, it may be obvious that all highway=tertiary are paved and all highway=track are not paved, but this kind of assumption does not work worldwide. Tagging at least some common values allows building a set of default values ​​for each area.

In the absence of surface=*, tracktype=* and other tags describing road quality, one may try to extrapolate this information from the value of the highway tag. This should be fine-tuned for each region.
