Traffic calming

Traffic calming is a package of measures introduced to control the movements of vehicles and other road traffic. This has a benefit not only on traffic flow and public services, but safety and the environment, too.

Traffic calming is also the term applied to physical measures which change the horizontal and/or vertical alignments of an otherwise normal road, examples being speed humps, build outs or coloured surfacing.

There are several technical and practical issues to consider when investigating the possibility of introducing traffic calming.

Getting traffic calming introduced

Due to funding constraints, we are not able to develop traffic calming schemes in the same manner as we have done historically.

We do not install traffic calming unless there is evidence of significant collision problems. We must prioritise limited funding to areas with an identified collision problem.

Things to consider when requesting new traffic management measures
 Consideration Comments



  • is the introduction of a restriction suitable for the area?
  • consider the advantages and disadvantages
  • does the road already have traffic calming features, such as signs, speed bumps and on-street parking?
  • if the proposal does not meet our various criteria, they are unlikely to be implemented.
Cost Would the proposals be achievable financially? Consider the costs of the advertisement, consultation and materials required, which can run into thousands of pounds 
  • do other residents agree that there is an issue in the area?
  • would the proposal inconvenience others?
  • if your concerns are related to traffic enforcement for driving offences, have you spoken to Dorset Police?
  • if implemented, would the restriction have the desired effect or will it introduce more problems?
  • will the introduction of a restriction just move the problem to another area?
