London public transport tagging scheme/TfL Barrier-Free
These are the standard elements used to model the indoor parts of the stations. For the entrances and all structures on the surface please see the London public transport tagging scheme
For this part of the tagging scheme, the same rules apply for all the different modes of transport.
Nodes
Elevators
These are the elevator nodes. They represent how the elevator connects walkways at different levels. For the elevator as building part or landmark please look at the area class lift shaft below.
Key | Values | Notes |
---|---|---|
highway | elevator | |
level | semicolon separated numbers | the level numbers of the connected levels |
indoor | yes | only if the structure is entirely underground or inside a building |
Ways
Connecting ways
Key | Values | Notes |
---|---|---|
highway | footway | |
level | number | the level number assigned by the operator |
tunnel | yes | only if the structure is underground |
indoor | yes | only if the structure is underground or inside a building |
Steps
Key | Values | Notes |
---|---|---|
highway | steps | |
step_count | number | TfL uses this information for barrier-free access options |
incline | up or down | |
level | semicolon separated numbers | the level numbers of the connected levels |
tunnel | yes | only if the structure is underground |
indoor | yes | only if the structure is underground or inside a building |
Escalators
Key | Values | Notes |
---|---|---|
highway | steps | |
conveying | forward, backward, or reversible | |
incline | up or down | |
level | semicolon separated numbers | the level numbers of the connected levels |
tunnel | yes | only if the structure is underground |
indoor | yes | only if the structure is underground or inside a building |
Ramps
Key | Values | Notes |
---|---|---|
highway | footway | |
incline | up or down | |
level | semicolon separated numbers | the level numbers of the connected levels |
tunnel | yes | only if the structure is underground |
indoor | yes | only if the structure is underground or inside a building |
Areas
Platforms
Key | Values | Notes |
---|---|---|
public_transport | platform | |
railway | platform | |
area | yes | |
ref | number | the number of the track if and only if the platform has one platform edge |
level | number | the level number assigned by the operator |
subway | yes | only if the structure is underground |
tunnel | yes | only if the structure is underground |
indoor | yes | only if the structure is underground or inside a building |
These structures shall be modeled by ways if they are simple polygons and by multipolygons if they have holes. In this case we recommend to map the platform edges explicitly as way with railway=platform_edge.
Walkable areas (e.g. halls)
Stations as well as underground stations often have halls of substantial width. These are modeled as areas with the following tags:
Key | Values | Notes |
---|---|---|
indoor | corridor | |
area | yes | |
level | number | the level number assigned by the operator |
tunnel | yes | only if the structure is underground |
These structures shall be modeled by ways if they are simple polygons and by multipolygons if they have holes.
The walkable areas inside buildings, esp. subway stations shall be connected to each other by footways to indicate which elements actually are connected. These areas and ways shall be connected to the rest of the city only through designated entrances.
Lift shafts
These structures represent the room occupied by the elevator or group of elevators in its entirety. The information what this elevator connects goes to the elevator node and not this shaft.
Key | Values | Notes |
---|---|---|
bulding:part | elevator | |
level | number | the level number of all levels where the shaft occupies space |
area | yes | |
indoor | yes | only if the structure is underground or inside a building |
