As 20mph limits become a defining feature of safer, more liveable streets across the UK, understanding how to deliver them successfully has never been more important. Delivering 20 – Making 20mph Work brings together leading experts to explore what the latest data, psychology, and policy thinking reveal about how communities can make lower speed limits effective, accepted, and enduring.

This focused, one and a half hour session will unpack the behavioural and cultural factors that shape the success of 20mph implementation, drawing lessons from Wales and beyond. Attendees will gain insights from new casualty data, learn from behavioural science research, and hear reflections on the evidence behind national reviews and professional guidance.

Topics include:

• Data and delivery: Latest Welsh casualty figures and the speed limit exceptions review – compared with DfT 2024 data for England. (Sue Nicholls)
• Insight Warehouse (presenter tbc): Update/report on UK 20mph road mapping - how Local Authorities are already changing behaviour
• Professional perspectives: Insights from the CIHT 2024 report on 20mph limits and evolving perceptions of their value. (Kate Carpenter)
• Behavioural change: Understanding the “Goodwin Curve” and how it applies to implementing 20mph policies. (Professor Phil Goodwin)

Chaired by Adrian Berendt, this webinar will close with a live Q&A session, giving participants the opportunity to put questions to the panel and explore how best to navigate the challenges of change.

Join us to learn how data, behaviour, and communication can combine to make 20mph work.
