<h2 id="H_1_1">Tags And Attributes</h2>
The different tags and attributes in the
<a class="ext" title="OpenStreetMap" href="http://www.openstreetmap.org/">OSM</a>
format XML that are used by Routino are described below.
<p>
Routino handles the tags in the input file after they have been processed
according to a set of rules defined in a configuration file. The first half of
this file describes the tags that are recognised by Routino after being
processed; the second half of the file describes the transformations that are in
the default tagging configuration file.
<!-- ==================== Tags Recognised After Processing ==================== -->
<h2 id="H_1_2" title="After Processing">Tags Recognised After Processing</h2>
This section describes the tags that are recognised by Routino after the tag
transformations have been applied. This is therefore a much reduced set of tags
compared to the original OSM data and also includes tags which are specific to
Routino.
<p>
In all cases of tag processing values of <em>true</em>, <em>yes</em>, <em>1</em>
are recognised as being affirmative and any other value is negative.
<!-- ========================= Routino Node Tags ========================= -->
<h3 id="H_1_2_1" title="Nodes">Node Tags And Attributes</h3>
The node attributes <em>id</em>, <em>latitude</em> and <em>longitude</em> are
used. The id attribute is required to associate the node with the ways and the
position attributes are required to locate the node.
<h4 id="H_1_2_1_1" title="transport tags">Transport Specific Tags</h4>
One tag is recognised for each of the different modes of transport: <em>foot</em>,
<em>horse</em>, <em>bicycle</em>, <em>wheelchair</em>, <em>moped</em>,
<em>motorcycle</em>, <em>motorcar</em>, <em>goods</em>, <em>hgv</em>
and <em>psv</em>. These indicate whether the specific type of transport is
allowed to pass through the node or not.
<p>
By default for nodes all types of transport are allowed to pass through a node
and specific tags must be used to remove the permissions for the transport.
<h4 id="H_1_2_1_2" title="roundabout (node)">The roundabout Tag</h4>
The <em>roundabout</em> tag for mini-roundabouts is recognised and used to
improve the description of the route.
<!-- ========================= Routino Way Tags ========================= -->
<h3 id="H_1_2_2" title="Ways">Way Tags And Attributes</h3>
The tags from the ways in the data are the ones that provide most of the
information for routing. The <em>id</em> attribute is used only so that the
many segments associated with a way can share a set of tags taken from the way.
The <em>nd</em> information is used to identify the nodes that make up the way.
<h4 id="H_1_2_2_1" title="highway (way)">The highway Tag</h4>
The most important tag that is used from a way is the <em>highway</em> tag.
This defines the type of highway that the way represents. Any way that does not
have a highway tag is discarded.
<p>
There are more highway types defined than are used by the router. The subset
that the router uses are:
<ul>
<li>motorway
<li>trunk
<li>primary
<li>secondary
<li>tertiary
<li>unclassified
<li>residential
<li>service
<li>track
<li>cycleway
<li>path (1)
<li>steps (2)
</ul>
<p>
<i>
Note 1: This changed in version 1.3 of Routino - the bridleway and footway
types were included within the path highway type.
<br>
Note 2: This changed in version 1.3 of Routino - the steps type was separated
from the footway type.
</i>
<h4 id="H_1_2_2_2" title="transport tags">Transport Specific Tags</h4>
One tag is recognised for each of the different modes of transport: <em>foot</em>,
<em>horse</em>, <em>bicycle</em>, <em>wheelchair</em>, <em>moped</em>,
<em>motorcycle</em>, <em>motorcar</em>, <em>goods</em>, <em>hgv</em>
and <em>psv</em>. These indicate whether the specific type of transport is
allowed on the highway or not.
<p>
By default for ways no types of transport are allowed to pass along a highway
and specific tags must be used to add the permissions for the transport.
<h4 id="H_1_2_2_3" title="name">The name Tag</h4>
The <em>name</em> tag is used to provide the label for the highway when printing
the results.
<h4 id="H_1_2_2_4" title="ref">The ref Tag</h4>
The <em>ref</em> tag is used to provide the label for the highway when printing
the results.
<h4 id="H_1_2_2_5" title="lanes">The lanes Tag</h4>
The <em>lanes</em> tag is used to identify whether a highway has multiple lanes
for traffic and this is used to derive the <em>multilane</em> highway
properties.
<h4 id="H_1_2_2_6" title="paved">The paved Tag</h4>
The <em>paved</em> tag is used to identify whether a highway is paved or not,
this is one of the available highway properties. A <em>paved</em> tag may exist
in the original data but normally the <em>surface</em> tag needs to be
transformed into the <em>paved</em> tag.
<h4 id="H_1_2_2_7" title="multilane">The multilane Tag</h4>
The <em>multilane</em> tag is used to indicate that a highway has multiple lanes
for traffic.
<h4 id="H_1_2_2_8" title="bridge">The bridge Tag</h4>
The <em>bridge</em> tag is used to identify whether a highway is a bridge and
therefore set one of the available properties.
<h4 id="H_1_2_2_9" title="tunnel">The tunnel Tag</h4>
The <em>tunnel</em> tag is used to identify whether a highway is a tunnel and
therefore set one of the available properties.
<h4 id="H_1_2_2_10" title="footroute">The footroute Tag</h4>
The <em>footroute</em> 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.
<h4 id="H_1_2_2_11" title="bicycleroute">The bicycleroute Tag</h4>
The <em>bicycleroute</em> tag is used to identify whether a highway is part of a
bicycle 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 bicycle access.
<h4 id="H_1_2_2_12" title="cyclebothways">The cyclebothways Tag</h4>
The <em>cyclebothways</em> tag is used to identify whether a highway allows
cycling in the opposite direction to a signposted oneway restriction.
<h4 id="H_1_2_2_13" title="oneway">The oneway Tag</h4>
The <em>oneway</em> tag is used to specify that traffic is only allowed to
travel in one direction.
<h4 id="H_1_2_2_14" title="roundabout (way)">The roundabout Tag</h4>
The <em>roundabout</em> tag is used to specify that a highway is part of a
roundabout to improve the description of the calculated route.
<h4 id="H_1_2_2_15" title="maxspeed">The maxspeed Tag</h4>
The <em>maxspeed</em> tag is used to specify the maximum speed limit on the
highway; this is always measured in km/hr in OpenStreetMap data. If the tag
value contains "mph" then it is assumed to be a value in those units and
converted to km/hr.
<h4 id="H_1_2_2_16" title="maxweight">The maxweight Tag</h4>
The <em>maxweight</em> tag is used to specify the maximum weight of any traffic
on the highway. In other words this must be set to the heaviest weight allowed
on the highway (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.
<h4 id="H_1_2_2_17" title="maxheight">The maxheight Tag</h4>
The <em>maxheight</em> tag is used to specify the maximum height of any traffic
on the highway. In other words this must be set to the lowest height of
anything above the highway (like a bridge) in metres. If the tag value contains
a measurement in feet or feet and inches then attempts are made to convert this
to metres.
<h4 id="H_1_2_2_18" title="maxwidth">The maxwidth Tag</h4>
The <em>maxwidth</em> tag is used to specify the maximum width of any traffic on
the highway. This must be set to the minimum width of the constraints at the
wayside in metres. If the tag value contains a measurement in feet or feet and
inches then attempts are made to convert this to metres.
<h4 id="H_1_2_2_19" title="maxlength">The maxlength Tag</h4>
The <em>maxlength</em> tag is used to specify the maximum length of any traffic
on the highway (usually from a traffic sign) in metres. If the tag value
contains a measurement in feet or feet and inches then attempts are made to
convert this to metres.
<h4 id="H_1_2_2_20" title="area">The area Tag</h4>
The <em>area</em> tag is used to specify that a way defines an area. This is
used only so that in the case of duplicated segments those belonging to an area
can be discarded in preference to those that are not.
<!-- ========================= Routino Relation Tags ========================= -->
<h3 id="H_1_2_3" title="Relations">Relation Tags And Attributes</h3>
The tags from the relations are used to associate more properties with the
highways that are part of that relation. The <em>id</em> attribute is used so
that relations that are members of other relations can be identified.
The <em>member</em> information is used to identify the nodes and ways that make
up the relation.
<h4 id="H_1_2_3_1" title="footroute">The footroute Tag</h4>
The <em>footroute</em> tag is used to identify whether a relation defines a
walking route and therefore should be applied to the individual member highways.
<h4 id="H_1_2_3_2" title="bicycleroute">The bicycleroute Tag</h4>
The <em>bicycleroute</em> tag is used to identify whether a relation defines a
bicycle route and therefore should be applied to the individual member highways.
<h4 id="H_1_2_3_3" title="type, restriction, except">The type, restriction & except Tags</h4>
For turn relations the information about the allowed or disallowed turns are
stored in the <em>type</em>, <em>restriction</em> and <em>except</em> tags. For
a turn restriction the <em>type</em> must be equal to "restriction",
the <em>restriction</em> must define the type of turn relation
and <em>except</em> defines transport types which are exempt from the
restriction.
<!-- ==================== Tag Transformations ==================== -->
<h2 id="H_1_3">Tag Transformations</h2>
This section describes the set of tag transformations that are contained in the
default configuration file. The configuration file tagging rules are applied in
sequence and this section of the document is arranged in the same order.
<!-- ==================== Node Tag Transformations ==================== -->
<h3 id="H_1_3_1" title="Nodes">Node Tag Transformations</h3>
<h4 id="H_1_3_1_1">Barrier Defaults</h4>
The first part of the tag transformations is to decide on defaults for each type
of node. This uses the <em>barrier</em> tag in the OSM file and converts it into
a default set of disallowed transport types.

<h4 id="H_1_3_1_2" title="Generic access">Generic Access Permissions</h4>
The <em>access</em> tag is used to specify the default access restrictions
through the node. If the tag value is <em>no</em> or <em>private</em> or a
selection of other values then all transport types are denied access (later tag
transformation rules may add specific transport types back again).
<h4 id="H_1_3_1_3" title="Other access">Other Access Permissions</h4>
A tag named <em>vehicle</em> means any of the <em>bicycle</em>, <em>moped</em>,
<em>motorcycle</em>, <em>motorcar</em>, <em>goods</em>, <em>hgv</em>
and <em>psv</em> transport types. A tag named <em>motor_vehicle</em> is
transformed to mean any vehicle except a <em>bicycle</em>.
<h4 id="H_1_3_1_4" title="Specific access">Specific Access Permissions</h4>
The final part of the access permissions is to use the specific transport type
tags.
<p>
One tag is recognised for each of the different modes of transport: <em>foot</em>,
<em>horse</em>, <em>bicycle</em>, <em>wheelchair</em>, <em>moped</em>,
<em>motorcycle</em>, <em>motorcar</em>, <em>goods</em>, <em>hgv</em>
and <em>psv</em>. These indicate whether the specific type of transport is
allowed through the node or not; the values listed for the <em>access</em> tag
are also accepted here.
<h4 id="H_1_3_1_5">Mini-roundabouts</h4>
If the <em>highway</em> tag has the value <em>mini_roundabout</em> or
the <em>junction</em> tag has the value <em>roundabout</em> then
a <em>junction</em> tag with value <em>roundabout</em>is passed through.
<!-- ==================== Way Tag Transformations ==================== -->
<h3 id="H_1_3_2" title="Ways">Way Tag Transformations</h3>
<h4 id="H_1_3_2_1">Highway Defaults</h4>
The first part of the tag transformations is to decide on defaults for each type
of highway. This uses the <em>highway</em> tag in the OSM file and maps it into
one of the <em>highway</em> tags that are recognised by Routino, defining the
default allowed transport types and adding a number of properties.
<p>
The first part of the highway tag checking is to ignore the <em>highway</em> tag
if it has a value that indicates a non-highway. These are the <em>proposed</em>
and <em>construction</em> values for future highways, the <em>no</em>,
<em>abandoned</em> and <em>disused</em> values for previous highways and a small
number of other values.
<p>
The second part of the highway transformation is to convert the <em>highway</em>
tag into one that is recognised by Routino.

<h4 id="H_1_3_2_2" title="Generic access">Generic Access Permissions</h4>
The <em>access</em> tag is used to specify the default access restrictions on
the highway. If the tag value is <em>no</em> or <em>private</em> or a selection
of other values then all transport types are denied access (later tag
transformation rules may add specific transport types back again).
<h4 id="H_1_3_2_3" title="Other access">Other Access Permissions</h4>
A tag named <em>vehicle</em> means any of the <em>bicycle</em>, <em>moped</em>,
<em>motorcycle</em>, <em>motorcar</em>, <em>goods</em>, <em>hgv</em>
and <em>psv</em> transport types. A tag named <em>motor_vehicle</em> is
transformed to mean any vehicle except a <em>bicycle</em>.
<p>
The <em>designation</em> tag is used as an alternative method of identifying the
legal right of way on a path (in the UK at least). The tag transformations
convert these tags into a set of allowed transport types as shown below.
<p>
<table>

</table>
<p>
In addition to these there are some other tags and values that will modify the
transport permissions on the highway.
<p>
A highway that is tagged as <em>motorroad</em> with a value of <em>yes</em> will
deny access to <em>foot</em>, <em>horse</em>, <em>wheelchair</em>,
<em>bicycle</em> and <em>moped</em> transport.
<p>
A highway that is tagged with <em>footway</em> or <em>sidewalk</em> and one of a
set of popular values will allow <em>foot</em> and <em>wheelchair</em> access
even if the road type would not normally do so.
<p>
A highway that is tagged as <em>cycleway</em> with one of several values will
allow bicycle access. If the value of the <em>cycleway</em> tag
is <em>opposite_lane</em>, <em>opposite_track</em> or <em>opposite</em> then
the <em>cyclebothways</em> tag is set.
<p>
A highway that is tagged as <em>oneway:bicycle</em> with the value <em>no</em>
will also cause the <em>cyclebothways</em> tag to be set.
<h4 id="H_1_3_2_4" title="Specific access">Specific Access Permissions</h4>
The final part of the access permissions is to use the specific transport type
tags.
<p>
One tag is recognised for each of the different modes of transport: <em>foot</em>,
<em>horse</em>, <em>bicycle</em>, <em>wheelchair</em>, <em>moped</em>,
<em>motorcycle</em>, <em>motorcar</em>, <em>goods</em>, <em>hgv</em>
and <em>psv</em>. These indicate whether the specific type of transport is
allowed on the highway or not.
<h4 id="H_1_3_2_5" title="Properties">Highway Properties</h4>
If there is a surface tag then the highway is assumed to be unpaved unless the
tag value matches one of the following: <em>paved</em>, <em>asphalt</em>,
<em>concrete</em> or many other values listed in the configuration file.
<p>
Support for the obsolete <em>paved</em> tag is also provided and the highway is
paved if this is set to a true value.
<p>
The <em>lanes</em> tag is passed through to be used to set the
<em>multilane</em> highway property.
<p>
The <em>bridge</em> and <em>tunnel</em> tags are copied directly from the input
to the output.
<h4 id="H_1_3_2_6" title="Restrictions">Highway Restrictions</h4>
The <em>oneway</em>, <em>maxspeed</em>, <em>maxweight</em>, <em>maxheight</em>,
<em>maxwidth</em> and <em>maxlength</em> are copied directly from the input to
the output without modification.
<h4 id="H_1_3_2_7">Roundabouts</h4>
If a highway is tagged as <em>junction=roundabout</em> then a
<em>roundabout=yes</em> tag created on the output.
<h4 id="H_1_3_2_8" title="Names and Refs">Highway Names and References</h4>
The <em>name</em> and <em>ref</em> tags are copied directly from the input to
the output.
<h4 id="H_1_3_2_9" title="Areas">Highway Areas</h4>
The <em>area</em> tag is copied directly from the input to the output.
<!-- ==================== Relation Tag Transformations ==================== -->
<h3 id="H_1_3_3" title="Relations">Relation Tag Transformations</h3>
The <em>type</em> tag is passed through without change.
<h4 id="H_1_3_3_1">Routes</h4>
The <em>route</em> tag can be used to determine whether a relation is part of a
walking or bicycle route so that the <em>footroute</em> or <em>bicycleroute</em>
properties can be applied to the highways that make up that relation.
<p>
The tag transformations that are applied for route relations are defined in the
table below.
