We are in the electronic (smart) era and therefore, these physical barriers should be avoided. I personally do not like to drive on these bumps. A smart controller should be used to regulate traffic flow.
Dear Amara Loulizi, I too have similar views regarding road humps. But you can see road humps and raised thresholds constructed to slow down traffic in local residential roads allover the world. Smart controllers to regulate traffic in local residential roads is a far away solution I feel. Anyhow I respect your views. Thanks for the answer.
