is_transitioning Flag Behavior for Lanes with LaneTransitionType = Split or Merge

Summary

In HERE Lanes data, lanes that have LaneTransitionType set to Split or Merge are flagged with is_transitioning = true by design.

Details

The is_transitioning attribute indicates that a lane is in a transitional state — either a new lane is forming (split) or an existing lane is ending/combining (merge).

Rules:

* When LaneTransitionType is set to Split or Merge, the system applies is_transitioning = true automatically.

Expected Behavior

| | |
| --- | --- |

| Merge | true |
| (none / other) | Determined by other rules |
