Traffic calming

Traffic calming is normally used in residential and urban areas, where by reducing the speed and volume of traffic passing through an area, the quality of the local environment can be improved for the people living in the area.

Deciding where traffic calming is needed

The Department for Infrastructure (DfI), in consultation with police, emergency services, bus companies and local residents' representatives, will decide whether a road needs traffic calming and, if so, which measures are most suitable.

One of the keys to a successful scheme is local community involvement. Local concerns identified through well-planned consultation will help to make sure that the suitable measures are provided.

Potential benefits of traffic calming

Traffic calming can:

  • reduce the number and severity of casualties resulting from road traffic collisions, especially those involving pedestrians and cyclists
  • discourage heavy vehicles and ‘through traffic’ from using unsuitable routes
  • reduce speeding
  • improve the urban street environment for local communities
  • promote a greater feeling of safety
  • promote cycling and walking

Road features used

Measures include:

  • road humps
  • mini roundabouts
  • footway build-outs
  • chicanes
  • priority junctions
  • central islands
  • reduced speed limits

Asking for traffic calming in your area

You need to contact the local DfI Roads divisional traffic management section for your area.

You can find contact details at these links:

You should explain why you feel traffic calming is needed.

They will carry out an assessment of the area. This will consider the following:

  • three-year road traffic injury collision history (as provided by the police)
  • vehicle speeds (recorded on site)
  • volume and type of traffic (recorded on site)
  • environmental reasons (presence of schools, playgrounds or shops)

Each requested traffic calming location is scored based on the above information. 

Traffic-calming measures are developed for the highest scoring locations and residents will be consulted about the proposed layout. 

Once a final layout is agreed, the Department then needs to successfully complete the necessary legislative procedures to allow the measures to be built.

Where traffic calming is not considered suitable, other measures such as signs and road markings may be used to improve road safety in the area.
