Node Tags And Attributes
------------------------
- None of the node tags are used but the node attributes id, latitude and
- longitude of the node. The id atribute is required to associate the
- node with the ways and the position attributes are required to locate
- the node.

+Transport Specific Tags
+- - - - - - - - - - - -
+
+ One tag is recognised for each of the different modes of transport:
+ foot, horse, bicycle, wheelchair, moped, motorbike, motorcar, goods,
+ hgv and psv. These indicate whether the specific type of transport is
+ allowed to pass through the node or not.
+

Way Tags And Attributes

allowed on the highway or not.

+ highway and specific tags must be used to add the permissions for the

The name Tag
- - - - - -
The tunnel tag is used to identify whether a highway is a tunnel and
therefore set one of the available properties.
+The footroute Tag
+- - - - - - - - -
+
+ The footroute tag is used to identify whether a highway is part of a
+ walking route and therefore set one of the available properties. This
+ is not a standard OSM tag and is normally added to the individual
+ highways by looking for route relations that are designated for foot
+ access.
+
+The bicycleroute Tag
+- - - - - - - - - -
+
+ The bicycleroute tag is used to identify whether a highway is part of a
+ bicycle route and therefore set one of the available properties. This

+ highways by looking for route relations that are designated for bicycle
+ access.

The oneway Tag

The maxweight tag is used to specify the maximum weight of any traffic
- on the way. In other words this must be set to the heaviest weight
- allowed on the way (for example a bridge) in tonnes. If the tag value
- contains "kg" then it is assumed that the value is in these units and
- converted to tonnes.

The maxheight Tag

The maxheight tag is used to specify the maximum height of any traffic

Relation Tags And Attributes
----------------------------
- Currently no relation tags or attributes are used.
+ The tags from the relations are used to associate more properties with
+ the highways that are part of that relation. The id attribute is used
+ so that relations that are members of other relations can be
+ identified.
+
+The footroute Tag
+- - - - - - - - -
+
+ The footroute tag is used to identify whether a relation defines a
+ walking route and therefore should be applied to the individual member
+ highways.

+
+ The bicycleroute tag is used to identify whether a relation defines a
+ bicycle route and therefore should be applied to the individual member

Tag Transformations
Node Tag Transformations
------------------------
- No transformations are applicable since no node tags are recognised.
+Barrier Defaults
+- - - - - - - -
+
+ The first part of the tag transformations is to decide on defaults for
+ each type of node. This uses the barrier tag in the OSM file and
+ converts it into a default set of disallowed transport types.
+
+ Barrier foot horse wheelchair bicycle moped motorbike motorcar goods hgv psv
+ ------- ---- ----- ---------- ------- ----- --------- -------- ----- --- ---
+ bollard yes yes yes yes yes yes no no no no
+ kissing_gate yes no no no no no no no no no
+ stile yes no no no no no no no no no
+ turnstile yes no no no no no no no no no
+Generic Access Permissions
+- - - - - - - - - - - - -
+
+ The access tag is used to specify the default access restrictions
+ through the node. If the tag value is no or private then all transport
+ types are denied access (later tag transformation rules may add
+ specific transport types back again).
+
+Other Access Permissions
+- - - - - - - - - - - -
+
+ A tag named vehicle means any of the bicycle, moped, motorbike,
+ motorcar, goods, hgv and psv transport types. A tag named motor_vehicle
+ is transformed to mean any vehicle except a bicycle.
+
+Specific Access Permissions
+- - - - - - - - - - - - - -
+
+ The final part of the access permissions is to use the specific
+ transport type tags.
+
+ One tag is recognised for each of the different modes of transport:
+ foot, horse, bicycle, wheelchair, moped, motorbike, motorcar, goods,
+ hgv and psv. These indicate whether the specific type of transport is
+ allowed through the node or not.
Way Tag Transformations
-----------------------
- - - - - - - - - - - - -

Relation Tag Transformations
----------------------------
- No transformations are applicable since no relation tags are recognised.
+Routes
+- - -
+
+ The route tag can be used to determine whether a relation is part of a
+ walking of bicycle route so that the footroute and bicycleroute
+ properties can be applied to the highways that make up that relation.
+
+ The tag transformations that are applied for route relations are
+ defined in the table below.
+
+ Relation Tag footroute Property bicycleroute Property
+ foot yes no
+ walking yes no
+ hiking yes no
+ bicycle no yes
+ bicycle;foot or foot;bicycle yes yes
