Segment length View history

Template:GlobalMark/visible When creating a segment, it is important to ensure that any individual segment is at least

  1. REDIRECT USA:Segment length/Minimum. It is less important to keep segments under any particular length, but there are drawbacks to long segments discussed below.

Length issues

Too short

When a segment is less than

  1. REDIRECT USA:Segment length/Minimum 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

  1. REDIRECT USA: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.

Too long

Segments longer than about 100km cannot be saved. In addition, there are several good reasons to keep segments shorter than 10km (though they should still not have unnecessary junctions):

  • 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 screen.

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 meters. The length does not appear before it is saved.

Fixing 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:

  1. REDIRECT USA:Necessary junctions

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

Fixing long segments

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