The 20mph default speed limit on all residential roads in Wales is part of a suite of measures to promote ‘liveable’ communities. 20mph limits have been implemented in many places in the UK but never on a national scale. A substantial shift in driver behaviour will be needed for the limit to achieve its desired effect.

This report aims to address two main questions:

  1. What specific behavioural interventions might be implemented to promote driver compliance with 20mph speed limits in residential areas; and
  2.  Are there particular demographics, community characteristics or other features that should form the basis of a segmentation approach?
