>What alternative would you suggest? Roads that are not straight, wide and well marked cause drivers to slow down naturally. Bushes trees and other landscaping can be used to make the road seem narrow which also makes people slow down. Having a good S-curve before the slow area works well too and many rural towns do this. For a school zone you should probably stick a traffic light at the school entrance since that will allow you to create a traffic clusterfuck in order to slow traffic for the hours when you want it slow and not reduce the capacity of the road the rest of the time. Turning it into a 4-way stop would probably work well since people approach those slowly since they have to stop anyway.
