Version 1
When a user is routed through an unnamed segment, Waze will automatically use the name of the next named segment on the route. This is useful for getting turn instructions on ramps and turn lanes. This, however, can be confusing in large parking lots.
When Waze uses a name for an unnamed segment
Waze sometimes uses a name for an unnamed segment in a driving instruction. When Waze gives driving directions to turn, exit, or "keep" onto an unnamed segment, it will look for a name it can use. If there is a named segment a little further along your route, it will use that name in the instruction.
As of January 2015[update], on most road types, this can be prevented. If "segment 1" is the segment following the "turn", "keep", or "exit" instruction:
the length of segment 1 and the unnamed segments that follow it adds up to 400m or more. OR
segment 1 is followed by 3 or more unnamed segments.
In this case, when Waze gives instructions to turn into this segment, it will not show or speak a name for the segment. These rules for prevention are ignored for ramp and freeway road types.
Version 2
When a user is routed through an unnamed segment, Waze will automatically use the name of the next named segment on the route (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 name inheritance
When Waze gives driving directions 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. This always works for freeways and ramps.
As of January 2015[update], on all other road types, this feature only works if:
the length of the unnamed segments is less (shorter?) than 400m, OR
there are no more than 3 unnamed segment in a row.
If the following, unnamed segments together are longer than 400 meter, or if there are 4 or more unnamed segments in a row, Waze will not show or speak a name in the instructions.
Examples
exit ramp
If a freeway exit ramp leads to a fork in the road, you can leave the name out of the exit ramp. Only name the ramp segments which go to a specific destination. Waze will use the name of the next named ramp after the unnamed exit ramp. This is only useful if the sign for the exit is the same as the sign for the named ramp.
cross street changes name at divided highway
an unnamed segment in the median of the divided roadway. If coming from segment A, over the unnamed median, Waze will use (inherit) the name of the next segment C in the instruction: "Go left to Main Street.
parking lot with unnamed roads
if there is a turn/keep instruction onto an unnamed road just before the named road outside the parking lot, Waze will give instructions to make a turn INSIDE the parking lot with a name from OUTSIDE the parking lot. This is confusing for drivers. For example, coming from segment A, if the next turn is a left at unnamed segment B, and than right to segment C (Main Street), Waze will give the instruction to turn left onto Main Street, while still in the middle of the parking lot road.
