20mph research study: process and impact evaluation: headline report

In July 2014, Atkins, AECOM and Professor Mike Maher of University College London, were commissioned by the Department for Transport to evaluate the effectiveness of 20mph (signed only) speed limits, based on twelve case study schemes in England and various comparator areas with a 30mph limit in place. The purpose of the research is to: 1. examine the perceptions and attitudes of different user groups towards 20mph speed limits; 2, strengthen the evidence base regarding the effectiveness of 20mph limits; 3. inform future policy development on 20mph speeds and limits at a national and local level; 4. identify lessons learned regarding the implementation and monitoring of 20mph signed only speed limits, to guide local authorities considering introducing 20mph limits. The study comprises a process evaluation which looks at why and how case study schemes were delivered, and an impact evaluation which examines the effectiveness of schemes in delivering intended outcomes. This report presents the headline findings and conclusions based on a broad range of quantitative and qualitative data sources. Further detail on the methodology, data sources and analysis undertaken is provided in the technical report.
