Glossary

The following terms are defined on this page to clarify the meaning of each of them as they relate to Waze. The are provided alphabetically for your convenience.

ASR - Automatic Speech Recognition

The ability of a smartphone to translate a user's voice commands into actions on the device

BGS - Big Green Sign

A large green sign is the US standard road signage for exits and other information.

Central reservation

Strip of land or barrier separating a dual carriageway. Also known as a median.

Cookies, cookie munching

Cookies are the dots on unconfirmed roads (sometimes called pacman roads). Cookie munching (or road munching) is driving over such roads. It also confirms the road is drivable for the Waze server.

Dead-end Node

The small white circle at the end of a road segment without another segment connected to its end

Directionality

Whether a road is one-way, two-way or Unknown.

Divided highway

See dual carriageway

Dual carriageway

A road or highway in which the two directions of traffic are separated by a central barrier or strip of land, known as a central reservation or median

Editable Area

A defined distance from the drives you have taken with Waze running within which you have rights to edit unlocked objects. You retain this area for approximately 90 days after each drive. So, for areas you drive regularly with Waze running, you will have this editable area all the time. For other areas, you ability to edit there will expire.

Express Lane

See HOV

Freeway

Motorway; the major road system in your country

Geometry

The layout or shape of a road segment. Each road is made up of straight line segments. These can be arbitrarily short, effectively allowing curves

Geometry Node (to be revised for latest editor)

When editing a segment or landmark, large white circles (previously large black squares) appear where the segment changes direction changing its shape. Click and drag them individually to alter the geometry of the segment or or landmark. Click and drag the small white circles on a segment to add them to an object or press the d key while the mouse is hovered over them to delete the geometry node.

Grade

The level or elevation of a road with respect to surrounding roads. So a road would normally be at level grade. A road going underneath in a tunnel would be a -1 grade. A road going over would be a +1 grade. At complicated junctions such as freeway interchanges there can be many levels. So on a flat map we assign levels to show that while the roads cross, they do not connect because they are at different heights or elevations.

HOV, HOV Lane - High Occupancy Vehicle

A vehicle with 2 or more occupants. HOV Lanes, also known as Carpool Lanes and Transit Lanes, are lanes restricted for the use of cars carrying a specified number of occupants

Intl or INTL

International abbreviation used to refer to the non-North America server infrastructure and location.

Junction or Junction Point

The point where two or more road segments connect; often 'incorrectly' referred to as a 'node'.

Junctions look differently depending on the situation:

• Selected and editable segment junction
  
• Selected and uneditable segment junction (no permissions to change)
  
• Changed, unsaved junction

Map tile, tile

The Waze map is divided into a grid using 1km-square areas which are called tiles or map tiles. Changes to map are processed on a per-tile basis. Changes to any part of a map tile causes Waze to mark the tile as changed and it will be rebuilt in the next map update cycle.

Median, median barrier

Strip of land or barrier separating a divided highway or motorway. Also known as a central reservation.

Motorway

Freeway; the major road system in your country

Munching

Driving over roads which have not previously been driven (pacman roads). Waze shows these with different coloring to entice drivers to drive them, thereby setting initial speed data. See cookie munching

NA

North America abbreviation.

Node

See Geometry Node

Origin

Starting point for a driving route, with the destination being the ending point.

Pacman roads

Unconfirmed roads marked with dots (cookies) that have not been driven upon since being created or significantly edited in the Waze Map Editor. Driving over these roads earns you points and turns your car icon into a Pacman-type character that "munches the dots"

Pathfinder

The road segments linking roadways that are not necessarily their own named streets. They are often part of the rampways getting on or off freeways and highways or between freeways. After initially exiting a freeway they help further direct drivers through additional turn decisions before reaching the desired roadway or street. See the Junction Style Guide for more information.

Pothole

Also called a kettle or chuckhole, is a type of disruption in the surface of a roadway where a portion of the road material has broken away, leaving a hole.

Ramp

A freeway entrance or exit; sliproad. Ramps may be on-ramps or off-ramps. Ramps used to connect roads at a different grade from the connecting road or freeway. See the Map Legend and the Junction Style Guide for more detail.

RevCon

See #Reverse Connectivity

Reverse Connectivity

A segment is defined in the Waze database as having a connection (turn allowed), via a junction, to another segment in a direction which goes against the directionality of at least one of the segments. This can cause routing irregularities.

Though it is hard to see this in the editor, two segments of a one-way road connected together could have an allowed "turn" in the opposite direction of the flow of traffic, or directionality, of the segments. This can be seen in the editor by turning both segments to 2-way and then seeing where the allowed turns are. The Color Highlighting userscript can also assist in identifying where reverse connectivity exists.

Road munching

Earning points by driving over roads (distance traveled). Also see cookie munching

Segment

Defines a section of roadway on which vehicles may travel or a pathway where only people may travel. Multiple segments are connected by junctions.

SelfCon

See #Self Connectivity

Self Connectivity

A segment is defined in the Waze database as having a connection, via a junction, back to itself. That can cause routing irregularities, but also may be the future of how to define a u-turn. As of today, self connectivity is not desirable. Tools such as the Color Highlighting userscript can help identify this situation.

Sliproad

A motorway entrance or exit; ramp. Sliproads are often at a different grade from the connecting road or motorway

TTS

Text-to-speech - Navigation instructions spoken to the driver by the Waze application

Update Request (UR)

An Update Request is a Map Issue reported by a user from the Waze client app. It is also a layer in the Map Editor. See update requests.

Wayfinder

See Pathfinder

Wazer

A user of the Waze application

WME

Abbreviation for Waze Map Editor

World

"Abbreviation" used to refer to the non-North America server infrastructure and location.
