A few people I know on Honor Oak Road and Perry Rise complain about vibrations whenever trucks go over the speed humps (particularly I suspect when going too fast).

Rumble strips are equally unfair on anybody trying to sleep or live close to such roads. They work well on trunk roads and in the countryside (outside villages), but are anti-social when implemented in residential areas.

Traffic lights that turn red if you are speeding (with cameras on top) can work well to reduce speeds as people know that if they slow down they will get where they want faster. But I don't think such measures are necessary on Fairlie Gardens.
