Original research: Effect of 20 mph speed limits on traffic injuries in Edinburgh, UK: a natural experiment and modelling study
https://jech.bmj.com/content/78/7/437
Conclusion: Our results indicate that the introduction of 20 mph limits resulted in a reduction in collisions and casualties 3 years post implementation. However, the effect exceeded expectations from changes in speed alone, possibly due to a wider network effect.
