In answer to the questions about cost (The Argus August 26 and 30): 20mph schemes represent very good value for money for taxpayers.

Brighton & Hove City Council confirmed earlier this year that a total of £788,578.60 has been spent on phases one and two of the current 20mph scheme in the city, covering the cost of consultation, road signs, road markings, etc.

Meanwhile, government figures suggest even a slight road traffic injury costs nearly £20,000 to deal with in terms of the emergency response, lost output, and expenditure by those affected.

More serious accidents cost many, many times more.

Of course, only some of the 978 injuries recorded in 2012 on the roads of Brighton and Hove occurred in areas which will benefit from 20mph.

But it’s clear that if slower speeds avoid even a few injuries, especially serious ones, the cost of implementation will be recovered very quickly.

If the indirect benefits of slower speeds in residential areas are added – more active people, more adventurous children, more pleasant public spaces, more cohesive communities, etc – 20mph limits represent even better value still.

That’s something all taxpayers should be happy about, not least those of us who drive.
