"no right on red" avoidance -- avoiding choke points and "queue across intersection"
"No right on red" avoidance (mentioned in "choke buster") would avoid a route that includes arriving at a major road where traffic tends queue across the intersection during peak hours.
Waze could also detect and actively avoid or reroute detours around intersections where other fleet movement would indicate the intersection is not clearing traffic during each traffic light cycle.

“Avoid difficult intersections” option is available in Navigation settings. Should ease the issue if not eliminate it.
