Statistical analysis of data in the May 2017 report "A review of recent installations of 20mph area schemes"

Alun Morris made this Freedom of Information request to Bath and North East Somerset Council

This request has been closed to new correspondence from the public body. Contact us if you think it ought be re-opened.

The request was successful.

Dear Bath and North East Somerset Council,

Your report of May 2017 “Setting Local Speed Limits...A review of recent installations
of 20mph area schemes (signage only)" draws conclusions from data sets, many of which have few data points.
I can find no reference to a statistical analysis of the significance of the changes in accident rates and casualty rates. Therefore it is an open question whether changes of such size would have occurred by chance and what reliable conclusions can be drawn.

I request all information and correspondence regarding statistical analysis of the data and also regarding whether to conduct such an analysis.

Yours faithfully,

Alun Morris

Information Governance, Bath and North East Somerset Council

Dear Bath and North East Somerset Council,

 

Your report of May 2017 “Setting Local Speed Limits...A review of recent
installations of 20mph area

schemes (signage only)" draws conclusions from data sets, many of which
have few data points.

I can find no reference to a statistical analysis of the significance of
the changes in accident rates and

casualty rates. Therefore it is an open question whether changes of such
size would have occurred by

chance and what reliable conclusions can be drawn.

 

I request all information and correspondence regarding statistical
analysis of the data and also regarding

whether to conduct such an analysis.

 

Yours faithfully,

 

Alun Morris
