When creating a segment, it is important to ensure that any individual segment is at least Segment length/Minimum. It is less important to keep segments under any particular length, but there are drawbacks to long segments discussed below.

Determine the length

The length of a segment can be determined after it is created and saved by selecting it and looking at the general tab with the segment selected. The length will be displayed toward the bottom of the tab in feet or miles (using the imperial unit setting in WME) or meters or kilometers (using the metric unit setting in WME). The length does not appear before it is saved.

The displayed length for both imperial and metric settings is based on a rounded metric number and does not reflect the actual segment length. However, a developer in the Waze editing community has developed a script called WME True Segment Length. This script will display the true length of the segment in both metric and imperial units with two decimal places of accuracy. Unfortunately, that display is not really important since the server only considers the rounded metric values.

Too short

When a segment is less than 5 m it becomes difficult for the navigation engine to determine traffic speed through that segment. That will in turn negatively affect drive time estimations and best routing.

Between intersections

There may be times when driveways or other roads join a main road with close proximity to each other. This may cause small segments to be created between the two junctions along that main road. If the segment is shorter than Segment length/Minimum, it may be best to simply merge the two intersections into a single junction. It is OK if the joining roads in the map do not exactly align with the visual map in the Waze Map Editor.

See the Junction Style Guide section on offset roads for more details about this situation.

Necessary short segments

There are a few instances where a single short segment may be present between two other segments with no other segments at those junctions. Sometimes these junctions are necessary and should not be removed. These include: Necessary junctions

In the above cases, the segment is necessary so it cannot be deleted, but it can be made at least the minimum length and still meet the needs of the original purpose.

Too long

Segments longer than about 62 miles (100 km) cannot be saved. In addition, there are several good reasons to keep segments shorter than 6.2 miles (10 km):

  • Long roadways or railroads with the city name present will cause a smudged city issue on the city layer.
  • Long segments require more resources in the client and WME to render on the screen.

Fixing long segments

Simply cut the segment to add one or more junction points. Each resulting segment should be shorter than the maximum length and longer than the minimum length.
