If people currently driving across from Grove Hill Road to Champion Hill wont. So they wont queue beside Dog kennel hill waiting for the green light. So Dog Kennel hill school should see a reduction in traffic idling besides their school.
Traffic displacement. If the traffic is coming along Avondale Rise it would need to turn left and join Dog kennel hill via Quorn or Pytchley. Both would be serious delays meaning much traffic will evaporate from the area. If they turn down Camberwell Grove they'll be delayed by the filtered traffic lights and then going through Camberwell Grove. Again much traffic will evaporate if they decide that is the next best alternative.
Minimal queue on Champion Park joining Denmark Hill currently. The loss of the through route E to W if it all went via via Champion Grove, the parallel A road would see that A road have less than 50% increase in traffic.
I do live on champion Hill - but I think such measures should be widespread. I'd personally prefer them to be cameras enforced and limited to non Southwark residents. No Southwark residents should be on our A & B roads not our unclassified residential streets. And vice cress when I'm in a car in other boroughs. It could also then be trisected to the most approripaite times of day, etc.
