Dropping a limit from 60 to 50 may well have a significant effect, but taking a road that is clearly designed for 50 and expecting traffic to drop to 30 with a bit of signage is not realistic. Now if the whole street were re-designed so it feels unsafe to go 40, you might get a better result.
Exactly. The speed limit and the road design limit should reinforce each other.
