Lane control
The lane tool can define connections or block particular paths through a junction.

What we know
Operations schematicConceptual
Locate the first persistent queue

Loading positionService time
DepartureExit clear?
Downstream pathCan the line move?
How to approach the decision
Editorial planning advice based on the confirmed systems above.
- Inspect a single problem movement, then change its connection.
- Watch downstream queues after changing a signal phase.
A mistake to avoid
Giving one movement more time can move the queue to another approach.
Unknown values and independent test scope
Signal timings, path-choice thresholds and optimal junction layouts.
Official documentation, historical developer statements and editorial inspection advice have separate scopes. Exact unobserved values remain Unknown. A published global patch does not establish an independent test of this guide.
