Navigation instructions for unnamed segments/Expanded
When a user is routed through an unnamed segment, Waze will automatically use the name of the next named segment on the route (AKA Road name inheritance). This is useful for getting instructions on ramps and turn lanes. This, however, can be confusing in other areas, like large parking lots.
Conditions for application
When Waze gives navigation instructions to "turn", "exit", or "keep" onto an unnamed segment, it will look for a name it can use. If there is a named segment further along your route, it will use (inherit) that name in the instruction. Named segments connected to the unnamed segment which are not part of your provided route, are not relevant.
The inherited name is only used in the displayed and spoken instruction prompts, it does not affect the actual name of the segment.
This always works forand .
As of January 2015[update], on all other road types (any road type which is not a Freeway or Ramp), this feature only works if:
- The combined length of the consecutive unnamed segments is shorter than 400 meters (1,312 feet),
- There are 3 or fewer unnamed segments in a row.
To explain the above conditions from another perspective: If the consecutive unnamed segments measured together are longer than 400 m (1,312 ft), or if there are 4 or more unnamed segments in a row, Waze will NOT show or speak a name in the instructions.
See the Best continuation article for details on how unnamed segments affect whether an instruction prompt will be given.
See the Wayfinder article for details on how to change what instruction prompt will be given at a fork.
- Roads which really don't have a name, may give confusing instructions if they meet the conditions for Road Name Inheritance. These roads may need to be mapped carefully in WME to avoid Waze giving confusing instructions to drivers to turn onto them using a name from further along their route. Some of the examples provided show this behaviour. Discuss these cases with senior editors when they arise, to decide the best way to map them.
- Road Name Inheritance can be used well for roads which do have the same name, specifically for freeway and highway ramp names. However in some cases this can cause issues and create a false best continuation. Always be cautious and test the map setup to ensure it produces the expected results.
