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.
What still needs live data
Signal timings, path-choice thresholds and optimal junction layouts.
We will update this guide before opening individual database records. Unverified shells are excluded from search and the sitemap.
