{{Construcción
Tunnel segments and places have unique editing considerations due to their underground setting. Drawing these segments and any underground junctions can be difficult with lack of aerial imagery and traffic data can be affected by the lack of GPS and/or cellular connections within tunnels. Tunnel places also have specific routing and display considerations dependent on the tunnel's primary use.

Los túneles no son diferentes de cualquier segmento(s) de carretera o vía de circulación, incluyendo puentes, viaductos, pasos sobre nivel, etc. Estos son dibujados y modificados de la misma forma en la que se hace con cualquier calle o vía utilizando los nodos para dar forma a la vía de circulación a través del túnel.


==Teoría de como funcionan==
==Theory of Operation==
La complicación con la navegación a través de túneles es que por lo general las conexiones de datos de comunicación GPS y teléfono celular dejan de funcionar. Los servidores de Waze rastrean cada dispositivo móvil (conductor) cuando entran y salen de cada segmento a lo largo de su ruta. Con los tiempos de inicio y fin de cada segmento, el servidor de Waze puede calcular la velocidad media de los conductores a través de ese segmento. Así es como el servidor de Waze puede determinar si el tráfico del túnel está fluyendo normalmente, o si hay una desaceleración de los vehículos en el túnel, incluso sin la información de seguimiento del GPS, mientras que el vehículo (conductor) se encuentra en el interior del túnel.
While tunnel segments gather data like any other road segment, navigation through tunnels is complicated by poor to absent GPS reception and/or cell phone data connections. The Waze servers track each Wazer as they enter and exit each segment along their route, calculating the average speed of Wazers through that segment. This allows the Waze servers to determine whether the tunnel traffic is flowing normally, even when GPS tracking information within the tunnel is absent. However, if a jam occurs within a tunnel where traffic cannot reach the other end to relay this information or if a tunnel has multiple segments / junctions within the tunnel, Waze may not be able to detect a slowdown of traffic.

===Beacons===
[[File:15 Waze beacon.png|frameless|alt=|left]]
Waze has partnered with municipalities, highway agencies, and other road organizations to install [https://www.waze.com/beacons Waze Beacons] in select tunnels globally. These battery-powered devices generate Bluetooth signals that provide location data to the app when the driver is out of GPS range within the tunnel. In tandem with a cellular data connection, this allows the app to provide real-time traffic data as it would with a typical GPS connection. Tunnel segments with installed beacons have had their geometry and attributes specifically set by staff to work properly with the beacons and should not be altered in the Waze Map Editor without Champ and/or staff approval.
==Tunnel Segments==


==Creación==
===Geometry===
Debido a los problemas de comunicación de los GPS y de transisión de datos del dispositivo móvil dentro de los túneles, el proceso de mapeo o seguimiento al interior del túnel es difícil, si no se sigue una trayectoria recta desde la entrada a la salida. El punto importante para el mapeo o trazado de cualquier túnel es al menos conectar las dos entradas, para permitir que el motor de enrutamiento pueda a utilizar la carretera y los puntos de entrada y proyectar como válido el punto de salida al otro lado del túnel.
Due to GPS and/or mobile device data communication problems inside tunnels, the mapping process of the tunnel is difficult if it does not follow a straight path from the entrance to the exit. The important point of any tunnel mapping is to at least connect the two entrances to enable the routing engine to use the roadway through the tunnel as appropriate for destinations on the other side of the tunnel.


Primero debes encontrar en el mapa las ubicaciones de las dos entradas del túnel. Si sabes que la carretera o vía sigue una trayectoria recta a lo largo del túnel, sólo tienes que dibujar un nuevo camino recto entre las dos entradas y darle a dicho segmento el nombre apropiado. Si no conoce la ruta del túnel personalmente, entonces debes comprobar el trazado o ruta con las trayectorias que registra el GPS de esa área. Si muestra una trayectoria consistente de curvas, entonces los dispositivos móviles activos son capaces de rastrear y comunicar los datos al servidor de Waze y usted debe diseñar la carretera siguiendo ese camino mediante la alteración de los nodos para ajustar la geometría y esta sea coincidente. Evitar la creación de segmentos separados de carretera si no hay cruces (divisiones o uniones) en el interior del túnel.
On the aerial imagery, find the locations of the two entrances of the tunnel. If you know that the tunnel is a straight path through, you can simply draw a new straight road between the two entrances and name the segment appropriately. If you are not personally familiar with the tunnel path, check for GPS tracks through that area. If it shows a consistent path of curves, then the active mobile devices are able to track and communicate the data back to the Waze server, and you should lay out the road following that path by altering the geometry nodes to match it. Avoid creating separate segments for the roadway if there are no junctions inside the tunnel.


Si conoce el camino y este tiene curvas y no hay curvas informadas por el GPS, entonces, tenga en cuenta la estimación acerca de dónde se encuentran las curvas en el interior y proceda a dar forma al segmento utilizando los nodos de geometría. Luego, una vez que el nuevo segmento de carretera está visible en la aplicaciónel cliente puede conducir a través de ese túnel y si el dispositivo móvil tiene la capacidad de generar sus propios GPS internos podrá estimar en dónde se encuentra su vehículo en relación a la carretera. Tenga en cuenta que el camino puede presentar curva(s) antes o después de la visualización del mapa, por lo que si esto ocurre usted podrá hacer los ajustes necestarios cuando regrese al editor de mapas más tarde. Aunque no es crítico que coincida exactamente, es útil para los conductores que la ruta visual sea similar al camino real a medida que pasan por la zona.
If you know that the roadway is curved by personal experience and there are no matching curved GPS tracks, consider estimating the path of the curves and shape the segment using the geometry nodes. Once that new roadway segment is live on the client app you can drive through that tunnel and if the mobile device has the ability to generate its own internal GPS estimate, you can estimate where on the map your vehicle is relative to the roadway. Note where the road turns before or after the map display and make adjustments when you return to the map editor later. Although it is not critical that it match exactly, it is helpful for drivers to have the visual route be similar to the real road as they pass through the area.


===Vista desde la Calle o Street View (SV)===
====Street View====
[[File:TunnelTracking.png|right|400px]]
Use [[Street View]] (SV) from the start of the tunnel to track the tunnel turns. The SV icon on the overhead map will automatically position itself on the roadway as you move forward. Align the overhead map view of the road segment to the SV icon. Continue through to the end of the tunnel.
Para los países que tengan disponible este [[Street View|servicio]], lo deben utilizar desde el inicio del túnel para poder registrar las curvas al interior de éste. El logo de SV en la parte superior del mapa, se posicionará automáticamente en la carretera mientras avanzas en ella. Continúa hasta el final de túnel.

Note the curve of the tunnel segment is visible in Street View.]]
{{clear}}
====Junctions====
Some roadways through tunnels include forks or exits to other roads inside the tunnel. Creating these junctions is done the same as with any other junction. As described in the section above, the GPS tracking and navigation may make it difficult to know exactly where in the tunnel that turn truly exists. In the case of junctions, it is more important to be more accurate in the estimate of the actual roadway fork or exit so the navigation instructions match the roadway as closely as possible. Street View can be a great help here if available.


==Cruces==
===Name===
Some roadways through tunnels include splits or exits to other routes inside the tunnel. Creating the split is done the same as with any other junction. As described in the section above, the GPS tracking and navigation may make it difficult to know exactly where in the tunnel that turn truly exists. In the case of splits and exits, it is more important to be more accurate in the estimate of the actual roadway split or exit so the navigation directions match the roadway as closely as possible. Street View (if available in your country) can be a great help here.
Tunnel segments should follow [[Road names|road name]] standards and should not be changed solely to the name of the tunnel unless it is the road's official name. If the tunnel's significance warrants the inclusion of the name for navigation purposes (i.e., as part of the "let's take..." TTS at the start of navigation, in hazard, closure, and other reports, etc.), the tunnel name can be appended to the primary name using a bullet (•) and proper [[abbreviations and acronyms]] (e.g., "I-376 W • Fort Pitt Tun").


==Peajes==
===Tunnel Checkbox [[File:Checkbox.png|50px]]===
Si un túnel requiere de pago de peaje para poder circular en él, utilice la práctica siguiente de [[Best_map_editing_practice#Toll_roads|peaje]] tal como lo haría con cualquier segmento de carretera o vía.
Ensure that the "Tunnel" checkbox is checked. This attribute provides several benefits across the Waze platform, including GPS trace filtering for the map editor, an alternative crosstime calculation logic for the routing server, and, within the app, user position extrapolation and night mode display toggling.
 
===Headlights Required Checkbox [[File:Checkbox.png|50px]]===
[[File:Headlights_required.png|border|right]]Consult the local state editing community to see whether a tunnel segment should have the "Headlights Required" box checked. Some states require headlights to be used in tunnels by law, whereas others encourage, but do not legally require, headlight use.
 
===Tolls===
If a tunnel requires a toll to be paid in order to pass through the tunnel, use the same [[Best_map_editing_practice#Toll_roads|toll road]] controls as for any other roadway segment. Tolls may be collected outside of the tunnel, so care should be taken to appropriately place the toll segment attribute.
 
===Elevation===
Tunnels should be set to -1 elevation (or lower if necessary for overlapping tunnel segments). Tunnel segments should generally be cut at least 15m/50ft before and after a tunnel to allow time for adequate GPS signal entering and leaving the segment. Do not cut segments for elevation purposes if the tunnel begins or ends within 60m/200ft of an existing junction.
 
==Tunnel Place==
Tunnel places can serve as a routing destination and as a landmark label on the map. As destinations, these places allow users to navigate to a tunnel entrance or to add the tunnel as a stop during navigation to get a preferred route. As a landmark, a tunnel place is represented by a label and polygon on the map to help users orient themselves relative to the rest of the map or identify which tunnel they are traversing.
 
===Geometry===
Active road tunnels should be added as area places. The geometry of the polygon should be limited to the area of the tunnel bore and care should be taken not to cover any open area between multiple bores if they are significantly spaced apart. This prevents the area place layer from covering portions of other map layers between the bores in the app (see [[Places/Bridge#Geometry|bridge place geometry]] for a visual example).
 
Tunnels that are not actively used for traffic (e.g., pedestrian and rail tunnels) should be added as point places to be used solely as a routing destination. As the features are below ground and non-navigable to road vehicles, they do not serve a purpose as a landmark.
 
===Address===
For active road tunnels, use the street name and city of the segments traversing the tunnel with no HN. If the segments on the tunnel are divided and labelled for each direction, the street name should not include the cardinal direction.
 
When a tunnel crosses two or more city names within a state:
 
*If the segments share a common street (primary or alternate), select that street name and check the none box for city
*If the segments do not share a common street (primary or alternate), check the none box for street and city
 
If a tunnel crosses state or country borders, select the state that encompasses a majority of the tunnel or consider mapping two area places in their respective state and/or country.
 
Tunnels that are not active road tunnels should have their address set like any other place.
 
===Name===
This should be an official or locally-used name, preferably signed at each approach. Do not map unnamed tunnels. Tunnels should follow the general standards for naming [[Places]]; do not abbreviate the word "Tunnel".
 
===Entry Points===
{{Mbox|type=important|text=As of April 2021, Multiple Entry Points (MEPs) are not usable in the production app. When adding entry points, keep in mind that production users are routed only to the originally created entry point.}}
Entry points should be added according to the navigation needs of the tunnel place:
 
*As a destination
**If a tunnel has (a) parking area(s) for pedestrian access near the approach for the tunnel and on the same road, they should be set as an entry points and named accordingly.
**If a tunnel does not have pedestrian access but has a nearby lot designated for parking, the entry point should be set to that lot
*As a routing aid
**For single bore with an undivided road, add a single entry point that allows a route to come from either direction. If the tunnel already has a destination entry point near the approach to one or both sides of the tunnel, this point does not need to be added.
**For a single bore with divided roads or multi-bore tunnels, an entry point should be added at the entrance of the tunnel from each direction to allow routing from the selected direction. The name of the points should indicate the direction of the segment they are set to.
 
===Lock===
Completed tunnel places should be locked to at least 2, though regional guidance may require a higher level based on road type, landmark importance, etc.

Tunnel segments and places have unique editing considerations due to their underground setting. Drawing these segments and any underground junctions can be difficult with lack of aerial imagery and traffic data can be affected by the lack of GPS and/or cellular connections within tunnels. Tunnel places also have specific routing and display considerations dependent on the tunnel's primary use.

Theory of Operation

While tunnel segments gather data like any other road segment, navigation through tunnels is complicated by poor to absent GPS reception and/or cell phone data connections. The Waze servers track each Wazer as they enter and exit each segment along their route, calculating the average speed of Wazers through that segment. This allows the Waze servers to determine whether the tunnel traffic is flowing normally, even when GPS tracking information within the tunnel is absent. However, if a jam occurs within a tunnel where traffic cannot reach the other end to relay this information or if a tunnel has multiple segments / junctions within the tunnel, Waze may not be able to detect a slowdown of traffic.

Wazers who select a navigation route that traverses a tunnel with beacons will receive a pop-up prompt at the start of navigation to turn on Bluetooth if it is off or not enabled for the Waze app.

Beacons

Waze has partnered with municipalities, highway agencies, and other road organizations to install Waze Beacons in select tunnels globally. These battery-powered devices generate Bluetooth signals that provide location data to the app when the driver is out of GPS range within the tunnel. In tandem with a cellular data connection, this allows the app to provide real-time traffic data as it would with a typical GPS connection. Tunnel segments with installed beacons have had their geometry and attributes specifically set by staff to work properly with the beacons and should not be altered in the Waze Map Editor without Champ and/or staff approval.

Tunnel Segments

Geometry

Due to GPS and/or mobile device data communication problems inside tunnels, the mapping process of the tunnel is difficult if it does not follow a straight path from the entrance to the exit. The important point of any tunnel mapping is to at least connect the two entrances to enable the routing engine to use the roadway through the tunnel as appropriate for destinations on the other side of the tunnel.

On the aerial imagery, find the locations of the two entrances of the tunnel. If you know that the tunnel is a straight path through, you can simply draw a new straight road between the two entrances and name the segment appropriately. If you are not personally familiar with the tunnel path, check for GPS tracks through that area. If it shows a consistent path of curves, then the active mobile devices are able to track and communicate the data back to the Waze server, and you should lay out the road following that path by altering the geometry nodes to match it. Avoid creating separate segments for the roadway if there are no junctions inside the tunnel.

If you know that the roadway is curved by personal experience and there are no matching curved GPS tracks, consider estimating the path of the curves and shape the segment using the geometry nodes. Once that new roadway segment is live on the client app you can drive through that tunnel and if the mobile device has the ability to generate its own internal GPS estimate, you can estimate where on the map your vehicle is relative to the roadway. Note where the road turns before or after the map display and make adjustments when you return to the map editor later. Although it is not critical that it match exactly, it is helpful for drivers to have the visual route be similar to the real road as they pass through the area.

Street View

Use Street View (SV) from the start of the tunnel to track the tunnel turns. The SV icon on the overhead map will automatically position itself on the roadway as you move forward. Align the overhead map view of the road segment to the SV icon. Continue through to the end of the tunnel.

Example of a tunnel segment in the Waze Map Editor with Street View. Note the curve of the tunnel segment is visible in Street View.

Junctions

Some roadways through tunnels include forks or exits to other roads inside the tunnel. Creating these junctions is done the same as with any other junction. As described in the section above, the GPS tracking and navigation may make it difficult to know exactly where in the tunnel that turn truly exists. In the case of junctions, it is more important to be more accurate in the estimate of the actual roadway fork or exit so the navigation instructions match the roadway as closely as possible. Street View can be a great help here if available.

Name

Tunnel segments should follow road name standards and should not be changed solely to the name of the tunnel unless it is the road's official name. If the tunnel's significance warrants the inclusion of the name for navigation purposes (i.e., as part of the "let's take..." TTS at the start of navigation, in hazard, closure, and other reports, etc.), the tunnel name can be appended to the primary name using a bullet (•) and proper abbreviations and acronyms (e.g., "I-376 W • Fort Pitt Tun").

Tunnel Checkbox

Ensure that the "Tunnel" checkbox is checked. This attribute provides several benefits across the Waze platform, including GPS trace filtering for the map editor, an alternative crosstime calculation logic for the routing server, and, within the app, user position extrapolation and night mode display toggling.

Headlights Required Checkbox

Consult the local state editing community to see whether a tunnel segment should have the "Headlights Required" box checked. Some states require headlights to be used in tunnels by law, whereas others encourage, but do not legally require, headlight use.

Tolls

If a tunnel requires a toll to be paid in order to pass through the tunnel, use the same toll road controls as for any other roadway segment. Tolls may be collected outside of the tunnel, so care should be taken to appropriately place the toll segment attribute.

Elevation

Tunnels should be set to -1 elevation (or lower if necessary for overlapping tunnel segments). Tunnel segments should generally be cut at least 15m/50ft before and after a tunnel to allow time for adequate GPS signal entering and leaving the segment. Do not cut segments for elevation purposes if the tunnel begins or ends within 60m/200ft of an existing junction.

Tunnel Place

Tunnel places can serve as a routing destination and as a landmark label on the map. As destinations, these places allow users to navigate to a tunnel entrance or to add the tunnel as a stop during navigation to get a preferred route. As a landmark, a tunnel place is represented by a label and polygon on the map to help users orient themselves relative to the rest of the map or identify which tunnel they are traversing.

Geometry

Active road tunnels should be added as area places. The geometry of the polygon should be limited to the area of the tunnel bore and care should be taken not to cover any open area between multiple bores if they are significantly spaced apart. This prevents the area place layer from covering portions of other map layers between the bores in the app (see bridge place geometry for a visual example).

Tunnels that are not actively used for traffic (e.g., pedestrian and rail tunnels) should be added as point places to be used solely as a routing destination. As the features are below ground and non-navigable to road vehicles, they do not serve a purpose as a landmark.

Address

For active road tunnels, use the street name and city of the segments traversing the tunnel with no HN. If the segments on the tunnel are divided and labelled for each direction, the street name should not include the cardinal direction.

When a tunnel crosses two or more city names within a state:

  • If the segments share a common street (primary or alternate), select that street name and check the none box for city
  • If the segments do not share a common street (primary or alternate), check the none box for street and city

If a tunnel crosses state or country borders, select the state that encompasses a majority of the tunnel or consider mapping two area places in their respective state and/or country.

Tunnels that are not active road tunnels should have their address set like any other place.

Name

This should be an official or locally-used name, preferably signed at each approach. Do not map unnamed tunnels. Tunnels should follow the general standards for naming Places; do not abbreviate the word "Tunnel".

Entry Points

As of April 2021, Multiple Entry Points (MEPs) are not usable in the production app. When adding entry points, keep in mind that production users are routed only to the originally created entry point.

Entry points should be added according to the navigation needs of the tunnel place:

  • As a destination
    • If a tunnel has (a) parking area(s) for pedestrian access near the approach for the tunnel and on the same road, they should be set as an entry points and named accordingly.
    • If a tunnel does not have pedestrian access but has a nearby lot designated for parking, the entry point should be set to that lot
  • As a routing aid
    • For single bore with an undivided road, add a single entry point that allows a route to come from either direction. If the tunnel already has a destination entry point near the approach to one or both sides of the tunnel, this point does not need to be added.
    • For a single bore with divided roads or multi-bore tunnels, an entry point should be added at the entrance of the tunnel from each direction to allow routing from the selected direction. The name of the points should indicate the direction of the segment they are set to.

Lock

Completed tunnel places should be locked to at least 2, though regional guidance may require a higher level based on road type, landmark importance, etc.
