Junctions with three or more connected segments are necessary if the segments themselves are supposed to intersect for routing purposes. Generally speaking, most two-segment junctions are not required, however some of them are required to ensure the best operation of Waze. The list below includes examples where a two-segment junction is necessary and should NOT be removed.

  • Loop roads. A single segment cannot loop back upon itself, so a junction is required to create two separate segments. It does not matter where the junction is located, so long as each segment meets the minimum segment length.
  • Road, city, or state name change. There are times when a road, city, or state name will change with no other intersecting road at that point. A junction is added to enable each side of the junction to have a different name.
  • Ramp or freeway splits. There are cases where a freeway may split into two separate freeways. In order to provide navigation to drivers, it may be necessary to create short segments on the freeway to show the two different road names at the split. Under certain situations it may be best to make the segments as short as possible, so long as each segment meets the minimum segment length. This is covered in detail in the Junction Style Guide.
  • The segment would otherwise be too long. See the article segment length for more information.
