Traffic calming

Traffic calming devices are used to improve road safety and the local environment. They work by controlling drivers' speeds to match local conditions. This section explains who installs them and how to request traffic calming in your area.

Road features used

Measures include:

  • road humps
  • speed cushions
  • build-outs
  • chicanes
  • rumble strips
  • traffic islands

Who decides where traffic calming is needed?

The highway or road authorities decide whether a road needs traffic calming and, if so, which measures are most suitable. The specific traffic problem will dictate the location, type and size of traffic calming measures. These are usually chosen after discussion with road safety officers, local residents and the emergency services.

How can I ask for traffic calming in my area?

You need to contact your local highway or road authority. Your local council should be able to put you in touch with them. You should explain why traffic calming is needed and the authority may then conduct an independent study to assess the problem.
