The British Medical Journal has published research on road safety indicating that 20mph zones can have a tremendous effect in reducing the number of accidents. The report's abstract says "The introduction of 20 mph zones was associated with a 41.9% (95% confidence interval 36.0% to 47.8%) reduction in road casualties, after adjustment for underlying time trends. The percentage reduction was greatest in younger children and greater for the category of killed or seriously injured casualties than for minor injuries. There was no evidence of casualty migration to areas adjacent to 20 mph zones, where casualties also fell slightly by an average of 8.0% (4.4% to 11.5%)."
This leads to the conclusion that "20 mph zones are effective measures for reducing road injuries and deaths".
This is something which is directly under the control of local authorities like Brent Council. Are there any suggestions for particularly dangerous parts of Kensal Green or Brent that would significantly benefit from a new 20mph zone?
