View source for User:Voludu2/Navigation instructions for unnamed segments View history

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 ==
{{:user:Voludu2/Navigation instructions for unnamed segments/Conditions}}

== Side effects ==
* 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 ===
:[[File:Inheritance_exit_ramp.PNG|thumb|right]]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 ===
:[[File:InheritanceDividedHighway.JPG|thumb|right]]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}}, 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.
