|Feature : Buses|
|A form of public transport|
Buses, coaches and trolley buses are forms of public transport that operate mainly on the road network. The system consists of bus routes calling at bus stops and bus stations and have a number of related features.

Stops and bus stations
The simplest way to map bus stops is using a node public_transport=platform and bus=yes beside the highway at the point where passengers would wait immediately prior to boarding the vehicle. This may be in a suitably positioned bus shelter, or by the bus stop pole. It might be a few meters from the point where one enters the vehicle. Add the name of the stop (as it appears on the stop, or on a timetable) using name=*.
If you like your bus stops to render on the main page, tag them additionally with highway=bus_stop. There is some talk about adding rendering for public_transport=platform, but it has not happened yet due to conflicting interests.
Bus/public transport stations
Bus services are mapped by marking all elements that belong to a route on members of a relation. This includes all the road segments (ways) the bus runs along and the bus stops (nodes or sometimes polygons) the route serves.
Route master relations
Bus lanes and tracks
- Main article: Bus lanes
There are two schemas in common use in OpenStreetMap for representing bus lanes on normal roads: the busway=* (or bus_bay=*) scheme which indicates the presence of at least one bus lane (or bay) on one or more sides of the road, and the lanes:psv scheme which provides a count of lanes reserved for public service vehicles (which include buses) and their directions. Both schemes are compatible with cycleways. Both can be used at the same time; for more information see Bus lanes.
The two commonly used schemas suffice for most maps. However lane-specific information applicable to bus lanes can be captured too with the advanced :lanes suffix.
Adding a bus route to OpenStreetMap
This method follows the Public Transport version 2 (PTv2) tagging schema.
Step 1 - Make sure that each bus stop in the route has been added to OpenStreetMap
Bus stops should, for more simplicity and ease, be added as a node at the location of the pole or shelter. Some stops have been added as ways or polygons, which is completely valid, however, adding the stops as nodes keeps the route cleaner and easier to maintain.
Some people use stop position nodes on the way covered by the route as well as using a node beside the road. Using a public transport stop position can be useful in some rare cases, but is usually unnecessary. The simple and encouraged way to add a bus stop is as a node at the location of the pole or shelter.
If a bus station is present with several stops all part of the same station, a stop area relation should be used to indicate that the stops are all part of the same station. Only the individual stops, and not the stop area relation, should be added to bus routes.
Add the following tags to the bus stop:
|public_transport=platform||Mandatory||For describing that this feature is a public transit platform, serving public transport routes. This is the correct tag to use for bus stops, even though it is not used in the same way as in common english. Bus stops, even if only a pole and some grass exist, should be given with this tag.||public_transport=platform|
|bus=yes||Mandatory||For indicating that buses stop at this platform.||bus=yes|
|highway=bus_stop||Optional||Add this tag if you would like to have the bus stop render on the main OSM page.||highway=bus_stop|
|name=*||Recommended||Name of the bus stop, especially when there exists no
||name=Martin Luther King Junior Boulevard at Stateside Drive|
|ref=*||Recommended||Reference code of the bus stop.||ref=3154|
|local_ref=*||Recommended||The reference of a bus stop in a bus station. If a bus station has a large number of buses arriving, many smaller bus stops, each with their own
|network=*||Recommended||The network of the bus stop. This can either be an abbreviation or full name, depending on the network. Check other bus routes or bus stops near the one being mapped to find out how the network should be tagged in the area.||network=CHT, network=London Buses, network=NYC Buses, network=TNSW|
|operator=*||Recommended||Name of the company operating the buses that stop at the bus stop. If several different operating companies serve the stop, use a semicolon (;) to separate the different operators in the value of the tag.||operator=Arriva|
|shelter=*||Recommended||'yes' if the stop is protected from the rain by a shelter. 'no' if it is not.||shelter=no|
|passenger_information_display=*||Recommended||'yes' if the stop has a real time electronic passenger information display. 'no' if not. Paper schedules do not count as passenger information displays.||passenger_information_display=yes|
|departures_board=timetable||Recommended||This tag indicates that a paper schedule with the usual arrival times of buses is present at the stop. departures_board=no indicates none.||departures_board=timetable|
|bench=*||Recommended||'yes' if a bench for riders to sit on is present at the stop. 'no' if not.||bench=yes|
|bin=*||Recommended||'yes' if there is a trash can at the bus stop. 'no' if not.||bin=no|
|tactile_paving=*||Recommended||'yes' if tactile paving (small bumps at the edge of the platform to alert visually impaired riders when they are walking into the road) are present. 'not' if not.||tactile_paving=no|
|layer=*||Mandatory in multi-level bus stations.||For where the associated road is not at ground level. Essential with complex multi-level situations where there would otherwise be doubt as to which road (or stop_position) it was associated.||layer=-1|
|lit=*||Recommended||'yes' if the bus stop is lit up at night. 'no' if not.||lit=yes|
|surface=*||Recommended||The surface of the ground where the bus stop is located.||surface=concrete|
After ensuring that each bus stop is present, move on to step 2.
Step 2 - Create the new bus relations
According to the PTv2 schema, one relation must be created for each variation of the route. For example, a bus route with both Northbound and Southbound buses should be mapped as two separate relations. If the bus route is a loop, only one relation is needed. If the bus route has some buses that start out half way through, serving only the second half of the route, but following the same route as other buses, a separate relation is needed for that variation.
To create the bus route relation for one of the directions the bus travels, select the first stop that the bus stops at and create and new relation from it.
Add the following tags to the new relation:
|type=route||Mandatory||For indicating that the relation is a route.||type=route|
|route=bus||Mandatory||For indicating that the route is a bus route.||route=bus|
|ref=*||Very important||For indicating the reference code of the route. If none exists, the name=* tag is required instead. The bus route must have some identifier to be useful.||ref=29C|
|public_transport:version=2||Important||This tag is useful for users of OSM transport data, because it lets them know that the route has been added according to the new system PTv2. It makes parsing and validating easier.||public_transport:version=2|
|roundtrip=*||Important||To specify whether the relation is a round trip. For most routes, the value is 'no'. Routes that complete a loop and are therefore only added with one relation should have the value 'yes'.||roundtrip=no|
|operator=*||Recommended||The name of the company or organization that operates the bus route.||operator=Triangle Transit Authority|
|network=*||Recommended||The network of the bus route. This can either be an abbreviation or full name, depending on the network. Check other bus routes or bus stops near the one being mapped to find out how the network should be tagged in your area.||network=CHT, network=London Buses, network=NYC Buses, and network=TNSW|
|opening_hours=*||Recommended||The opening hours of the bus route. This should include the time between the first bus of the day starting out (in the direction being mapped - different directions can have different opening hours) to the time of the last bus of the day arriving at the last stop of the route.||opening_hours=Mo-Fr 07:23-18:44|
|duration=*||Recommended||The duration of the bus route, or the time between the bus leaving the first stop and arriving at the last stop. Use HH:MM format. The example on the right states that the bus runs for 31 minutes from end to end.||duration=00:31|
|fee=*||Recommended||'yes', if a fee is required for riding the bus route, and an optional (but still important) charge=* for the amount of the fee. 'no', if no fee is required.||fee=yes+charge=$2.25|
|bicycle=*||Recommended||'yes' if bicycles are permitted on the bus. Buses that permit bicycles often have racks on the front for storing them.||bicycle=yes|
|wheelchair=*||Recommended||'yes' if wheelchairs are accommodated. 'no' if not. Routes that accommodate wheelchairs have special ramps that can be laid down for wheelchairs to enter the bus. There will be a dedicated area in the bus for wheelchairs that may have straps or a cushioned pad that the wheelchair can the reversed up to and the brakes applied to hold a wheelchair in place.||wheelchair=yes|
|from=*||Recommended||The name of the location where the bus is coming from. This does not have to be the name of the bus stop.||from=Southern Village|
|via=*||Recommended||The name of an important stop along the route. Many bus routes do not have an important via stop, so in the case of trying to add such a route, don't use this tag.||via=Franklin Street|
|to=*||Recommended||The name of the destination of the bus. Many buses display a banner across the top of the bus with the destination.||to=Eubanks Road Park and Ride Lot|
|name=*||Recommended||The 'name' of a bus route should follow a specific format and is not the official name of the bus route. This tag is more of a description of the route than the actual name of the route. To add the name, use the following format: "name"="Bus <ref>: <from> => <to>". If the bus route has a "via", you can use "name"="Bus <ref>: <from> => <via> => <to>", however using via in the name is optional. Note that "->", "-->", or "→" can be used instead of "=>". Use which ever style you like. As long as the ref=*, from=*, and to=* tags are filled out, data users can create their own names however they prefer.
If the bus route is a round trip, the "to" and "from" tags will be the same, causing a rather silly bus route name to be tagged (eg. Bus 27B: Downtown => Brightley => Downtown). In the case of such a bus route, you can choose to use "Bus <ref>" as the name. Example: name=Bus 27B.
|name=Bus 405: UNC Hospitals => Downtown Durham Transit Center|
|official_name=*||Recommended||For describing the name of the bus route as used on official maps. Most routes have only a reference number and not a name, so for those cases, don't use this tag.||official_name=Bull City Connector|
|colour=*||Recommended||The color of the bus route on official maps. Many bus routes do not have an "official color", so for those routes, simply don't use this tag. The color should be in hex format, however, using HTML color codes will work as well.||colour=#58912F|
Adding bus stops to the relation
The next step is to add each bus stop to the bus route relation in the correct order with the role "platform".
It is very important that the stops be added to the route relation in the order that the bus stops at them. If the bus stops at a stop twice, add that stop to the relation twice. Each stop must have the role "platform" in the route relation. Although many people use the role "stop" for the bus stops, the role is now discouraged.
Some platforms / bus stops have entry only/exit only restrictions. For those cases, use the roles "platform_exit_only" and "platform_entry_only" instead of the role "platform".
Adding streets to the relation
The final step is to add the streets covered by the bus route in the correct order with the role "platform".
To add streets to the relation properly, select the first street that the bus drives over after leaving the first stop in the route. You may need to split the street to only select the part of it that is covered by the bus route. Add the first street covered by the bus route to the relation with an empty role. Then, add the next street covered by the route, and then the next, all in the correct order. Adding the streets in the correct order is just as important as it is for the stops. Using the roles "forward", "backward", "both", "North", "South", "twice", or any other role is invalid. Each street must be added with an empty role (""). The direction that the bus travels on the way can very easily be found by a computer (as long as the member ways are connected), and using roles other than an empty role for streets covered by the bus route is therefore both unnecessary and invalid.
The relation is now finished.
Step 3 - Create a route master relation
Now that each direction of the bus route has been added as a separate relation, they should be connected with a route master relation. The route master relation should include both directions of the route, as well as any variations of the route. For example, if a bus route operates normally Monday through Friday, but has a different route and different opening hours on weekends, then the weekend routes (both directions) should be added as separate relations, for a total of four relations. All relations that are part of the same route should be added to the route master relation.
|type=route_master||Mandatory||To specify that this relation is a route master.||type=route_master|
|route_master=bus||Mandatory||To specify that this route master is a bus route master.|
|ref=*||Mandatory||If no ref exists, you must use official_name=* instead.||ref=800|
|name=*||Recommended||As is true with the individual bus relations, this value should not be the "official" name of the bus route.
Use the following format: "Bus <ref>".
|operator=*||Recommended||Name of the company that operates this bus route.||operator=Transport for London|
|network=*||Recommended||The network of the bus route master. Look to other public transport features in your area to see what the common value of the network=* tag is for your local transit network.||network=London Buses|
|official_name=*||Recommended, if one exists.||For the name of the bus route as it appears on official maps. If no official name exists, don't use this tag.||official_name=Bull City Connector|
|ref:<qualifier>=*||Important, if several refs exist.||The reference by which an operator or network, specified by <qualifier>, refers to the route or service. Important, where the reference code of the bus route is known by two or more different refs depending on which operator is contacted.||ref:OPT=OCH & ref:TTA=420|
Add the child bus route relations to the route master.
After adding the necessary tags to the route master relation, add each of the individual routes to the route master with an empty role, or ("").
- Main article: Relation:network#Public transportation networks
A network relation can be used to link each member of a network together. The network relation represents existing networks (i.e. a common fare system). Network relations can be hard to work with, and have therefore been depreciated in some places (for example Germany). Using network=* on each bus route and route master relation is preferred over network relations.
Example bus routes
Chapel Hill Transit NS: route master relation
London Buses route 12: route master relation
Removing a bus route from OpenStreetMap
When entire lines disappear their route_master and route relations are deleted. Unless the bus stops have also been physically removed, they should not be deleted. If they are renamed and/or their identifier changes and it's obvious that it's all based on an already mapped predecessor, you could 'reuse' the relations. There is no good way to indicate when the new situation starts or the old situation ceases.
