When a user is routed through an unnamed segment, Waze will automatically use the name of the next named segment on the route (a.k.a. road name inheritance). This is useful for getting instructions for ramps and turn lanes. However, this can be confusing in other areas, like large parking lots without road names.
Be sure to understand how unnamed segments operate during navigation before adding names to unnamed segments already on the map.
Conditions for application
When Waze gives navigation instructions to "turn", "exit", or "keep" onto an unnamed segment, it will look ahead on your route 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 but which are not part of your provided route will not be used.
The inherited name is only used in the displayed and spoken instruction prompts, it does not affect the actual name of the segment. Unnamed segemnts are often used to help control instructions on ramps and turn lanes. Be sure to understand all the ways in which unnamed segments can affect navigation and navigation instructions before adding names to unnamed segments or removing them from named segments.
This always works for Freeways and Ramps . This never works for Parking Lot Roads .
As of October 2018[update], on all other road types (any road type which is not a Freeway, Ramp, or Parking Lot), this feature only works if:
The combined length of the consecutive unnamed segments is shorter than 400 meters (1,312 feet), AND
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.
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 behavior. Discuss these cases with senior editors when they arise, to decide the best way to map them.
Road name Inheritance can be very useful 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 instruction. Always be cautious and test the map setup to ensure it produces the expected results.
Examples
Exit ramp
If a freeway exit ramp leads to a fork in the road, you can leave the name off of the exit ramp. Only name the segments which go to a specific destination. Waze will use the name of the next named segment after the unnamed exit ramp. This is only useful if the sign for the exit is the same as the sign for the next named segment.
Connecting street between the lanes of a divided highway
If routing from segment A (US-202 N) over the unnamed segment, Waze will use (inherit) the name of the next segment B in the instruction: "Go left to Beta Blvd" If routing from segment C (US-202 S) over the unnamed segment, Waze will use (inherit) the name of the next segment D in the instruction "Go left to Delaney Dr".
Parking lot with unnamed roads
As of October 2018[update], instructions for maneuvers (exit, keep, turn, continue) onto unnamed parking lot road segments do not include a name. Prior to October 2018, Waze did look ahead on the route and often used a name found on a road outside the parking lot for turns inside the parking lot. This was caused by a known side effect of the look ahead/ inheritance feature which was changed for the October 2018 release.
